Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. limine-10.3.0/libfdt/BSD-2-Clause0000644000000000000000000000315115103344045014715 0ustar rootrootValid-License-Identifier: BSD-2-Clause SPDX-URL: https://spdx.org/licenses/BSD-2-Clause.html Usage-Guide: To use the BSD 2-clause "Simplified" License put the following SPDX tag/value pair into a comment according to the placement guidelines in the licensing rules documentation: SPDX-License-Identifier: BSD-2-Clause License-Text: Copyright (c) .

Included is a fast framebuffer backend. ### Quick usage To quickly set up and use a framebuffer Flanterm instance, it is possible to use the `flanterm_fb_init()` function as such: ```c #include #include struct flanterm_context *ft_ctx = flanterm_fb_init( NULL, NULL, framebuffer_ptr, width, height, pitch, red_mask_size, red_mask_shift, green_mask_size, green_mask_shift, blue_mask_size, blue_mask_shift, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, 0, 0, 1, 0, 0, 0 ); ``` Where `framebuffer_ptr, width, height, pitch` and `{red,green,blue}_mask_{size,shift}` represent the corresponding info about the framebuffer to use for this given instance. The meaning of the other arguments can be found in `flanterm_backends/fb.h`. To then print to the terminal instance, simply use the `flanterm_write()` function on the given instance. For example: ```c #include const char msg[] = "Hello world\n"; flanterm_write(ft_ctx, msg, sizeof(msg)); ``` limine-10.3.0/flanterm/LICENSE0000644000000000000000000000242115103344044014360 0ustar rootrootCopyright (C) 2022-2025 mintsuki and contributors.

This file serves as the protocol's specification and as the official, centralised collection of [features](#features) that the Limine boot protocol is comprised of. Bootloaders may support extra unofficial features, but it is strongly recommended to avoid fragmentation and submit new features by opening a pull request to the [limine-protocol Codeberg repository](https://codeberg.org/Limine/limine-protocol). The [limine.h](include/limine.h) file provides an implementation of all the structures and constants described in this document, for the C and C++ languages. --- ## Table of Contents - [General Notes](#general-notes) - [Requests Delimiters](#requests-delimiters) - [Limine Requests Section](#limine-requests-section) - [Base Revisions](#base-revisions) - [Base Revision Changes Summary](#base-revision-changes-summary) - [Base Revision 0](#base-revision-0) - [Base Revision 1](#base-revision-1) - [Base Revision 2](#base-revision-2) - [Base Revision 3](#base-revision-3) - [Base Revision 4](#base-revision-4) - [Memory Layout at Entry](#memory-layout-at-entry) - [Caching](#caching) - [x86-64](#x86-64) - [aarch64](#aarch64) - [riscv64](#riscv64) - [loongarch64](#loongarch64) - [Machine State at Entry](#machine-state-at-entry) - [x86-64](#x86-64-1) - [aarch64](#aarch64-1) - [riscv64](#riscv64-1) - [loongarch64](#loongarch64-1) - [Features](#features) - [Request](#request) - [Response](#response) - [Feature List](#feature-list) - [Bootloader Info](#bootloader-info-feature) - [Executable Command Line](#executable-command-line-feature) - [Firmware Type](#firmware-type-feature) - [Stack Size](#stack-size-feature) - [HHDM (Higher Half Direct Map)](#hhdm-higher-half-direct-map-feature) - [Framebuffer](#framebuffer-feature) - [Paging Mode](#paging-mode-feature) - [MP (Multiprocessor)](#mp-multiprocessor-feature) - [RISC-V BSP Hart ID](#risc-v-bsp-hart-id-feature) - [Memory Map](#memory-map-feature) - [Entry Point](#entry-point-feature) - [Executable File](#executable-file-feature) - [Module](#module-feature) - [RSDP](#rsdp-feature) - [SMBIOS](#smbios-feature) - [EFI System Table](#efi-system-table-feature) - [EFI Memory Map](#efi-memory-map-feature) - [Date at Boot](#date-at-boot-feature) - [Executable Address](#executable-address-feature) - [Device Tree Blob](#device-tree-blob-feature) - [Bootloader Performance](#bootloader-performance-feature) - [File Structure](#file-structure) --- ## General Notes The "executable" is the kernel or otherwise the freestanding application being loaded by the Limine boot protocol compliant bootloader. The Limine boot protocol does not enforce any specific executable binary format to use, though ELF is strongly recommended. Only 64-bit, Little Endian machines are supported or will be supported in the future. All pointers are 64-bit wide. All non-NULL pointers point to the object with the [Higher Half Direct Map](#hhdm-higher-half-direct-map-feature) (HHDM) offset already added to them, unless otherwise noted. All [responses](#response) and associated data structures are placed in [bootloader-reclaimable memory](#memory-map-feature) regions. The ABIs the Limine protocol uses and expects the executable to comply with are as follows: - SysV Itanium ABI for x86-64 - AAPCS LP64 for aarch64 - LP64 for riscv64 - LP64S for loongarch64 All of these are with FPU/SIMD disabled (sometimes also referred to as Soft-Float). ## Requests Delimiters The bootloader can be told to start and/or stop searching for [requests](#request) (including [base revision](#base-revisions) tags) in an executable's loaded image by placing start and/or end markers, on an 8-byte aligned boundary. The bootloader will only accept requests placed between the last start marker found (if there happen to be more than 1, which there should not, ideally) and the first end marker found. ```c #define LIMINE_REQUESTS_START_MARKER { 0xf6b8f4b39de7d1ae, 0xfab91a6940fcb9cf, \ 0x785c6ed015d3e316, 0x181e920a7852b9d9 } #define LIMINE_REQUESTS_END_MARKER { 0xadc0e0531bb10d03, 0x9572709f31764c62 } ``` For base revisions [0](#base-revision-0) and [1](#base-revision-1), the requests delimiters are *hints*. The bootloader can still search for requests and base revision tags outside the delimited area if it doesn't support the hints. [Base revision 2](#base-revision-2)'s sole difference compared to [base revision 1](#base-revision-1) is that support for request delimiters has to be provided and the delimiters must be honoured, if present, rather than them just being a hint. ## Limine Requests Section > [!WARNING] > This behaviour is deprecated and removed as of [base revision 1](#base-revision-1) For executables requesting deprecated [base revision 0](#base-revision-0), if the executable file contains a `.limine_reqs` executable section, the bootloader will, instead of scanning the whole executable's loaded image for [requests](#request), fetch the requests from a NULL-terminated array of pointers to the provided requests, contained inside said section. ## Base Revisions The Limine boot protocol comes in several base revisions; so far, 5 base revisions are specified: [0 through 4](#base-revision-changes-summary). Base revisions change certain behaviours of the Limine boot protocol outside any specific feature. The specifics are going to be described as needed throughout this specification, but are also coalesced in the [Base Revision Changes Summary](#base-revision-changes-summary) section. Base revision 0 through 3 are considered deprecated. [Base revision 0](#base-revision-0) is the default base revision an executable is assumed to be requesting and complying to if no base revision tag is provided by the executable, for backwards compatibility. A base revision tag is a set of 3 64-bit values placed somewhere in the loaded executable image on an 8-byte aligned boundary; the first 2 values are a magic number for the bootloader to be able to identify the tag, and the last value is the requested base revision number. ```c #define LIMINE_BASE_REVISION(N) { 0xf9562b2d5c95a6c8, 0x6a7b384944536bdc, (N) } ``` If a bootloader drops support for an older base revision, the bootloader must fail to boot an executable requesting such base revision. If a bootloader does not yet support a requested base revision (i.e. if the requested base revision is higher than the maximum base revision supported), it must boot the executable using any arbitrary revision it supports, and communicate failure to comply to the executable by *leaving the 3rd component of the base revision tag unchanged*. On the other hand, if the executable's requested base revision is supported, *the 3rd component of the base revision tag must be set to 0 by the bootloader*. > [!NOTE] > This means that unlike when the bootloader drops support for an older base > revision and *it* is responsible for failing to boot the executable, in case the > bootloader does not yet support the executable's requested base revision, > it is up to the executable itself to fail (or handle the condition otherwise). For any Limine-compliant bootloader supporting [base revision 3](#base-revision-3) or greater, it is *mandatory* to load executables requesting higher unsupported base revisions with at least base revision 3, and it is mandatory for it to always set the 2nd component of the base revision tag to the base revision actually used to load the executable, regardless of whether it was the requested one or not. ```c #define LIMINE_BASE_REVISION_SUPPORTED(VAR) ((VAR)[2] == 0) #define LIMINE_LOADED_BASE_REVISION_VALID(VAR) ((VAR)[1] != 0x6a7b384944536bdc) #define LIMINE_LOADED_BASE_REVISION(VAR) ((VAR)[1]) ``` ## Base Revision Changes Summary This section consolidates all changes introduced by each [base revision](#base-revisions) for easy reference. ### Base Revision 0 This is the default base revision used if no base revision tag is provided. - Supports the `.limine_reqs` executable section for providing a list of [requests](#request). - Request delimiters (start/end markers) are treated as hints only. - Identity mapping (starting at offset 0x1000) available. - [HHDM](#hhdm-higher-half-direct-map-feature) (Higher Half Direct Map) covers **all** memory map regions. - Memory between 0 and 0x1000 is **never** marked as usable in the [memory map](#memory-map-feature). - **aarch64**: `TTBR0_EL1` points to bootloader-provided identity mapping page tables. ### Base Revision 1 **Changes from Base Revision 0**: - Dropped support for the `.limine_reqs` executable section [request](#request) search method. - Dropped identity mapping. - [HHDM](#hhdm-higher-half-direct-map-feature) mappings no longer include [memory map regions](#memory-map-feature) of types: - Reserved - Bad memory - **aarch64**: `TTBR0_EL1` is now **unspecified** and can be freely used by the executable. - [Requests delimiters](#requests-delimiters) remain hints only. ### Base Revision 2 **Changes from Base Revision 1**: - [Requests delimiters](#requests-delimiters) must now be **honoured** if present (no longer optional hints). - All other behaviors remain the same as [base revision 1](#base-revision-1). ### Base Revision 3 **Changes from Base Revision 2**: - [HHDM](#hhdm-higher-half-direct-map-feature) mapping becomes **restrictive** - only the following [memory map regions](#memory-map-feature) are mapped: - Usable - Bootloader reclaimable - Executable and modules - Framebuffer - Dropped unconditional direct map of the first 4 GiB of memory to the [Higher Half Direct Map](#hhdm-higher-half-direct-map-feature). - Memory between 0 and 0x1000 **can now** be marked as usable in the [memory map](#memory-map-feature). - [RSDP](#rsdp-feature) address is returned as **physical** (base revision 3 **only**). - [SMBIOS](#smbios-feature) entry point addresses are returned as **physical**. - [EFI system table](#efi-system-table-feature) address is returned as **physical**. - **Bootloader requirement**: Must support loading executables requesting higher unsupported revisions with at least base revision 3. - **Bootloader requirement**: Must set the 2nd component of the base revision tag to the actual base revision used. ### Base Revision 4 **Changes from Base Revision 3**: - [HHDM](#hhdm-higher-half-direct-map-feature) additionally maps the following [memory map regions](#memory-map-feature): - ACPI tables - ACPI reclaimable - ACPI NVS - Added new [memory map](#memory-map-feature) region type: `LIMINE_MEMMAP_ACPI_TABLES`. - Guaranteed that ACPI tables (RSDP, RSDT, XSDT, all tables pointed to by RSDT and XSDT, FACS, X_FACS, DSDT, X_DSDT) are mapped within any of the ACPI [memory map regions](#memory-map-feature). - [RSDP](#rsdp-feature) address is returned as **virtual** **([HHDM](#hhdm-higher-half-direct-map-feature))** again (physical only in [base revision 3](#base-revision-3)). - **aarch64**: - `MAIR_EL1.Attr0` is guaranteed to be `0xff` (Normal Write-Back RW-Allocate non-transient). - `MAIR_EL1.Attr1` is guaranteed to be the framebuffer's correct caching type. - All other `MAIR_EL1` entries are guaranteed unused unless specified by a request (no such requests are specified yet). ## Memory Layout at Entry The protocol mandates executables to load themselves at or above `0xffffffff80000000`. Lower half executables are *not supported*. For relocatable executables asking to be loaded at address 0, a minimum slide of `0xffffffff80000000` is applied. A "slide" is an offset applied to the executable's base load address. At handoff, the executable will be properly loaded and mapped with appropriate MMU permissions, as supervisor, at the requested virtual memory address (provided it is at or above `0xffffffff80000000`). No specific physical memory placement is guaranteed, except that the loaded executable image is guaranteed to be physically contiguous. In order to determine where the executable is loaded in physical memory, see the [Executable Address feature](#executable-address-feature). Alongside the loaded executable, the bootloader will set up memory mappings as such: ``` Base Physical Address | | Base Virtual Address ----------------------+-------------------------------+----------------------- | (4 GiB - 0x1000) and any | 0x0000000000001000 | additional memory map region | 0x0000000000001000 | (Base revision 0 only) | ----------------------+-------------------------------+----------------------- | 4 GiB and additional | 0x0000000000000000 | memory map regions depending | HHDM start | on base revision | ``` Where "HHDM start" is returned by the [Higher Half Direct Map feature](#hhdm-higher-half-direct-map-feature). These mappings are supervisor, read, write, execute (-rwx). When a memory map region is mapped to the Higher Half Direct Map, mappings will use a minimum page size of 4KiB; if a region's start or end address is not 4KiB aligned, the mappings will overshoot the region boundaries in order to align to 4KiB while also covering the entire region. For [base revision 0](#base-revision-0), the above-4GiB identity and HHDM mappings cover any memory map region. For [base revisions 1](#base-revision-1) and [2](#base-revision-2), the above-4GiB HHDM mappings do not comprise memory map regions of types: - Reserved - Bad memory For [base revision 3](#base-revision-3) or greater, the only memory map regions mapped to the HHDM are: - Usable - Bootloader reclaimable - Executable and modules - Framebuffer Additionally, the unconditional direct map of the first 4GiB is dropped, and only memory map regions of complying types are mapped in. For [base revision 4](#base-revision-4) or greater, the following regions are also mapped in addition to those mapped by [base revision 3](#base-revision-3): - ACPI tables - ACPI reclaimable - ACPI NVS The bootloader page tables are in [bootloader-reclaimable memory](#memory-map-feature) (see the [Memory Map feature](#memory-map-feature)), and their specific layout is undefined as long as they provide the above memory mappings. If the executable is a position independent executable, the bootloader is free to relocate it as it sees fit, potentially performing slide randomisation. ## Caching ### x86-64 The executable, loaded at or above `0xffffffff80000000` in virtual memory, sees all of its segments mapped using write-back (WB) caching at the page tables level. That being `PAT[0]`, if the PAT is supported. All HHDM and identity map memory regions are mapped using write-back (WB) caching at the page tables level (again, `PAT[0]`), except framebuffer regions which are mapped using write-combining (WC) caching at the page tables level (`PAT[5]`, if the CPU support the PAT, see below). If the CPU supports the PAT (Page Attribute Table), its layout is specified to be as follows: ``` PAT0 -> WB PAT1 -> WT PAT2 -> UC- PAT3 -> UC PAT4 -> WP PAT5 -> WC PAT6 -> unspecified PAT7 -> unspecified ``` The MTRRs are left as the firmware set them up. ### aarch64 The executable, loaded at or above `0xffffffff80000000` in virtual memory, sees all of its segments mapped using Normal Write-Back RW-Allocate non-transient caching mode (`MAIR_EL1.Attr0`). All HHDM and identity map memory regions are mapped using the Normal Write-Back RW-Allocate non-transient caching mode (guaranteed to be in `MAIR_EL1.Attr0` for [base revision 4](#base-revision-4) or greater), except for the framebuffer regions, which are mapped in using an unspecified caching mode (guaranteed to be in `MAIR_EL1.Attr1` for [base revision 4](#base-revision-4) or greater), correct for use with the framebuffer on the platform. For base revisions < 4, the `MAIR_EL1` register will at least contain entries for the above-mentioned caching modes, in an unspecified order. For [base revision 4](#base-revision-4) and greater, `MAIR_EL1.Attr0` is guaranteed to be `0xff` (AKA Normal Write-Back RW-Allocate non-transient caching mode), `MAIR_EL1.Attr1` is guaranteed to be the entry used to map the framebuffer, of the correct caching type for it, and all other entries in `MAIR_EL1` are guaranteed unused unless otherwise specified by a request (no such requests are specified yet). ### riscv64 The executable, loaded at or above `0xffffffff80000000`, in virtual memory, and all HHDM and identity map memory regions are mapped with the default `PBMT=PMA`. If the `Svpbmt` extension is available, all framebuffer memory regions are mapped with `PBMT=NC` to enable write-combining optimizations. If the `Svpbmt` extension is not available, no PMAs can be overridden (effectively, everything is mapped with `PBMT=PMA`). ### loongarch64 The executable, loaded at or above `0xffffffff80000000`, in virtual memory, sees all of its segments mapped using the Coherent Cached (CC) memory access type (MAT). All HHDM and identity map memory regions are mapped using the Coherent Cached (CC) MAT, except for the framebuffer regions, which are mapped in using the Weakly-ordered UnCached (WUC) MAT. ## Machine State at Entry ### x86-64 `rip` will be the entry point as defined as part of the executable file format, unless the [Entry Point feature](#entry-point-feature) is requested, in which case, the value of `rip` is going to be taken from there. At entry all segment registers are loaded as 64 bit code/data segments, limits and bases are ignored since this is 64-bit mode. The GDT register is loaded to point to a GDT, in [bootloader-reclaimable memory](#memory-map-feature), with at least the following entries, starting at offset 0: - Null descriptor - 16-bit code descriptor. Base = `0`, limit = `0xffff`. Readable. - 16-bit data descriptor. Base = `0`, limit = `0xffff`. Writable. - 32-bit code descriptor. Base = `0`, limit = `0xffffffff`. Readable. - 32-bit data descriptor. Base = `0`, limit = `0xffffffff`. Writable. - 64-bit code descriptor. Base and limit irrelevant. Readable. - 64-bit data descriptor. Base and limit irrelevant. Writable. The IDT is in an undefined state. Executable must load its own. IF flag, VM flag, and direction flag are cleared on entry. Other flags undefined. PG is enabled (`cr0`), PE is enabled (`cr0`), PAE is enabled (`cr4`), WP is enabled (`cr0`), LME is enabled (`EFER`). NX is enabled (`EFER`) if available. If 5-level paging is requested and available, then 5-level paging is enabled (LA57 bit in `cr4`). The A20 gate is opened. Legacy PIC (if available) and IO APIC IRQs (only those with delivery mode fixed (0b000) or lowest priority (0b001)) are all masked. If booted by EFI, boot services are exited. `rsp` is set to point to the top of a stack, in [bootloader-reclaimable memory](#memory-map-feature), which is at least 64KiB (65536 bytes) in size, or the size specified in the [Stack Size feature](#stack-size-feature). An invalid return address of 0 is pushed to this stack before jumping to the executable's entry point. All other general purpose registers (`rax`-`r15`) are set to 0. ### aarch64 `PC` will be the entry point as defined as part of the executable file format, unless the [Entry Point feature](#entry-point-feature) is requested, in which case, the value of `PC` is going to be taken from there. The contents of the `VBAR_EL1` register are undefined, and the executable must load its own. The `MAIR_EL1` register contents are described above, in the [caching section](#caching). All interrupts are masked (`PSTATE.{D, A, I, F}` are set to 1). The executable is entered in little-endian AArch64 EL1t (EL1 with `PSTATE.SP` set to 0, `PSTATE.E` set to 0, and `PSTATE.nRW` set to 0). Other fields of `PSTATE` are undefined. At entry: the MMU (`SCTLR_EL1.M`) is enabled, the I-Cache and D-Cache (`SCTLR_EL1.{I, C}`) are enabled, data alignment checking (`SCTLR_EL1.A`) is disabled. SP alignment checking (`SCTLR_EL1.{SA, SA0}`) is enabled. Other fields of `SCTLR_EL1` are reset to 0 or to their reserved value. Higher ELs do not interfere with accesses to vector or floating point instructions or registers. Higher ELs do not interfere with accesses to the generic timer and counter. The used translation granule size for both `TTBR0_EL1` and `TTBR1_EL1` is 4KiB. `TCR_EL1.{T0SZ, T1SZ}` are set to 16 under 4-level paging, or 12 under 5-level paging. Additionally, for 5-level paging, `TCR_EL1.DS` is set to 1. `TTBR1_EL1` points to the bootloader-provided higher half page tables. For [base revision 0](#base-revision-0), `TTBR0_EL1` points to the bootloader-provided identity mapping page tables, and is unspecified for all other base revisions and can thus be freely used by the executable. If booted by EFI, boot services are exited. `SP` is set to point to the top of a stack, in [bootloader-reclaimable memory](#memory-map-feature), which is at least 64KiB (65536 bytes) in size, or the size specified in the [Stack Size feature](#stack-size-feature). All other general purpose registers (including `X29` and `X30`) are set to 0. Vector registers are in an undefined state. ### riscv64 At entry the machine is executing in Supervisor mode. `pc` will be the entry point as defined as part of the executable file format, unless the [Entry Point feature](#entry-point-feature) is requested, in which case, the value of `pc` is going to be taken from there. `x1`(`ra`) is set to 0, the executable must not return from the entry point. `x2`(`sp`) is set to point to the top of a stack, in [bootloader-reclaimable memory](#memory-map-feature), which is at least 64KiB (65536 bytes) in size, or the size specified in the [Stack Size feature](#stack-size-feature). `x3`(`gp`) is set to 0, executable must load its own global pointer if needed. All other general purpose registers, with the exception of `x5`(`t0`), are set to 0. If booted by EFI, boot services are exited. `stvec` is in an undefined state. `sstatus.SIE` and `sie` are set to 0. `sstatus.FS` and `sstatus.XS` are both set to `Off`. Paging is enabled with the paging mode specified by the [Paging Mode feature](#paging-mode-feature). The (A)PLIC, if present, is in an undefined state. ### loongarch64 At entry the machine is executing in PLV0. `$pc` will be the entry point as defined as part of the executable file format, unless the [Entry Point feature](#entry-point-feature) is requested, in which case, the value of `$pc` is going to be taken from there. `$r1`(`$ra`) is set to 0, the executable must not return from the entry point. `$r3`(`$sp`) is set to point to the top of a stack, in [bootloader-reclaimable memory](#memory-map-feature), which is at least 64KiB (65536 bytes) in size, or the size specified in the [Stack Size feature](#stack-size-feature). All other general purpose registers, with the exception of `$r12`(`$t0`), are set to 0. If booted by EFI, boot services are exited. `CSR.EENTRY`, `CSR.MERRENTRY` and `CSR.DWM0-3` are in an undefined state. `PG` in `CSR.CRMD` is 1, `DA` is 0, `IE` is 0 and `PLV` is 0 but is otherwise unspecified. `CSR.TLBRENTRY` is filled with a provided TLB refill handler. ## Features The protocol is centered around the concept of request/response - collectively named "features" - where the executable requests some action or information from the bootloader, and the bootloader responds accordingly, if it is capable of doing so. In C terms, a feature is comprised of 2 structures: the request, and the response. ### Request A request has 3 mandatory members at the beginning of the structure: ```c struct limine_example_request { uint64_t id[4]; uint64_t revision; struct limine_example_response *response; ... optional members follow ... }; ``` * `id` - The ID of the request. This is an 8-byte aligned magic number that the bootloader will scan for inside the loaded executable image to find requests. Request IDs are composed of 4 64-bit unsigned integers, but the first 2 are common to every request: ```c #define LIMINE_COMMON_MAGIC 0xc7b1dd30df4c8b88, 0x0a82e883a194f07b ``` Requests may be located anywhere inside the loaded executable image as long as they are 8-byte aligned. There may only be 1 of the same request. The bootloader will refuse to boot an executable with multiple of the same request IDs. * `revision` - The revision of the request that the executable provides. This starts at 0 and is bumped whenever new members or functionality are added to the request structure. Bootloaders process requests in a backwards compatible manner, *always*. This means that if the bootloader does not support the revision of the request, it will process the request as if it were the highest revision that the bootloader supports. * `response` - This field is filled in by the bootloader at load time, with a pointer to the response structure, if the request was successfully processed. If the request is unsupported or was not successfully processed, this field is *left untouched*, meaning that if it was set to `NULL`, it will stay that way. ### Response A response has only 1 mandatory member at the beginning of the structure: ```c struct limine_example_response { uint64_t revision; ... optional members follow ... }; ``` * `revision` - Like for requests, bootloaders will instead mark responses with a revision number. This revision is not coupled between requests and responses, as they are bumped individually when new members are added or functionality is changed. Bootloaders will set the revision to the one they provide, and this is *always backwards compatible*, meaning higher revisions support all that lower revisions do. This is all there is to features. For a list of official Limine features, read the "Feature List" section below. ## Feature List ### Bootloader Info Feature ID: ```c #define LIMINE_BOOTLOADER_INFO_REQUEST_ID { LIMINE_COMMON_MAGIC, 0xf55038d8e2a1202f, 0x279426fcf5f59740 } ``` Request: ```c struct limine_bootloader_info_request { uint64_t id[4]; uint64_t revision; struct limine_bootloader_info_response *response; }; ``` Response: ```c struct limine_bootloader_info_response { uint64_t revision; char *name; char *version; }; ``` `name` and `version` are 0-terminated ASCII strings containing the name and version of the loading bootloader. ### Executable Command Line Feature ID: ```c #define LIMINE_EXECUTABLE_CMDLINE_REQUEST_ID { LIMINE_COMMON_MAGIC, 0x4b161536e598651e, 0xb390ad4a2f1f303a } ``` Request: ```c struct limine_executable_cmdline_request { uint64_t id[4]; uint64_t revision; struct limine_executable_cmdline_response *response; }; ``` Response: ```c struct limine_executable_cmdline_response { uint64_t revision; char *cmdline; }; ``` `cmdline` is a 0-terminated ASCII string containing the command line associated with the booted executable.

ID: ```c #define LIMINE_PAGING_MODE_REQUEST_ID { LIMINE_COMMON_MAGIC, 0x95c1a0edab0944cb, 0xa4e5cb3842f7488a } ``` Request: ```c struct limine_paging_mode_request { uint64_t id[4]; uint64_t revision; struct limine_paging_mode_response *response; uint64_t mode; /* Request revision 1 and above */ uint64_t max_mode; uint64_t min_mode; }; ``` * `mode` - the preferred paging mode by the OS; the bootloader should always aim to pick this mode unless unavailable or overridden by the user in the bootloader's configuration file. * `max_mode` - the highest paging mode in numerical order that the OS supports. The bootloader will refuse to boot the OS if no paging modes of this type or lower (but equal or greater than `min_mode`) are available. * `min_mode` - the lowest paging mode in numerical order that the OS supports. The bootloader will refuse to boot the OS if no paging modes of this type or greater (but equal or lower than `max_mode`) are available. If no Paging Mode Request is provided, the values of `mode`, `max_mode`, and `min_mode` that the bootloader assumes are `LIMINE_PAGING_MODE__DEFAULT`, `LIMINE_PAGING_MODE__DEFAULT`, and `LIMINE_PAGING_MODE__MIN`, respectively. If request revision 0 is used, the values of `max_mode` and `min_mode` that the bootloader assumes are the value of `mode` and `LIMINE_PAGING_MODE__MIN`, respectively. Response: ```c struct limine_paging_mode_response { uint64_t revision; uint64_t mode; }; ``` The response indicates which paging mode was actually enabled by the bootloader. #### x86-64 Values assignable to `mode`, `max_mode`, and `min_mode`: ```c #define LIMINE_PAGING_MODE_X86_64_4LVL 0 #define LIMINE_PAGING_MODE_X86_64_5LVL 1 #define LIMINE_PAGING_MODE_X86_64_DEFAULT LIMINE_PAGING_MODE_X86_64_4LVL #define LIMINE_PAGING_MODE_X86_64_MIN LIMINE_PAGING_MODE_X86_64_4LVL ``` #### aarch64 Values assignable to `mode`, `max_mode`, and `min_mode`: ```c #define LIMINE_PAGING_MODE_AARCH64_4LVL 0 #define LIMINE_PAGING_MODE_AARCH64_5LVL 1 #define LIMINE_PAGING_MODE_AARCH64_DEFAULT LIMINE_PAGING_MODE_AARCH64_4LVL #define LIMINE_PAGING_MODE_AARCH64_MIN LIMINE_PAGING_MODE_AARCH64_4LVL ``` #### riscv64 Values assignable to `mode`, `max_mode`, and `min_mode`: ```c #define LIMINE_PAGING_MODE_RISCV_SV39 0 #define LIMINE_PAGING_MODE_RISCV_SV48 1 #define LIMINE_PAGING_MODE_RISCV_SV57 2 #define LIMINE_PAGING_MODE_RISCV_DEFAULT LIMINE_PAGING_MODE_RISCV_SV48 #define LIMINE_PAGING_MODE_RISCV_MIN LIMINE_PAGING_MODE_RISCV_SV39 ``` #### loongarch64 Values assignable to `mode`, `max_mode`, and `min_mode`: ```c #define LIMINE_PAGING_MODE_LOONGARCH_4LVL 0 #define LIMINE_PAGING_MODE_LOONGARCH_DEFAULT LIMINE_PAGING_MODE_LOONGARCH_4LVL #define LIMINE_PAGING_MODE_LOONGARCH_MIN LIMINE_PAGING_MODE_LOONGARCH_4LVL ``` ### MP (Multiprocessor) Feature ID: ```c #define LIMINE_MP_REQUEST_ID { LIMINE_COMMON_MAGIC, 0x95a67b819a1b857e, 0xa0b61b723b6a73e0 } ``` Request: ```c #define LIMINE_MP_REQUEST_X86_64_X2APIC (1 << 0) struct limine_mp_request { uint64_t id[4]; uint64_t revision; struct limine_mp_response *response; uint64_t flags; }; ``` * `flags` - Bit 0: Enable x2APIC, if possible.

The executable should make absolutely sure that no data contained in these regions is still needed before deciding to reclaim these memory regions for itself. Refer to the ACPI specification for further information. * `LIMINE_MEMMAP_ACPI_NVS` entries represent regions of the address space used for ACPI non-volatile data storage. Refer to the ACPI specification for further information. * `LIMINE_MEMMAP_BAD_MEMORY` entries represent regions of the address space that contain bad RAM, which may be unreliable, and therefore these regions should be treated the same as reserved regions. * `LIMINE_MEMMAP_BOOTLOADER_RECLAIMABLE` entries represent regions of the address space containing RAM used to store bootloader or firmware information that should be available to the executable (or, in some cases, hardware, such as for MP trampolines). The executable should make absolutely sure that no data contained in these regions is still needed before deciding to reclaim these memory regions for itself. * `LIMINE_MEMMAP_EXECUTABLE_AND_MODULES` entries are meant to have an illustrative purpose only, and are not authoritative sources to be used as a means to find the addresses of the executable or modules. One must use the specific Limine features ([Executable Address](#executable-address-feature) and [Module](#module-feature) features) to do that. * `LIMINE_MEMMAP_FRAMEBUFFER` entries represent regions of the address space containing memory-mapped framebuffers. These entries exist for illustrative purposes only, and are not to be used to acquire the address of any framebuffer. One must use the [Framebuffer feature](#framebuffer-feature) for that. * `LIMINE_MEMMAP_ACPI_TABLES` ([base revision 4](#base-revision-4) or greater) entries represent regions of the address space containing the ACPI tables as described by the [Memory Layout at Entry](#memory-layout-at-entry) section, if the firmware did not already map them within either an ACPI reclaimable or an ACPI NVS region. For [base revisions](#base-revisions) <= 2, memory between 0 and 0x1000 is never marked as usable memory. For [base revision 4](#base-revision-4) or greater, ACPI tables (that being RSDP, RSDT, XSDT, all tables pointed to by RSDT and XSDT, FACS, X_FACS, DSDT, X_DSDT - if present) are guaranteed to be mapped within any of the 3 ACPI memory map regions. The entries are guaranteed to be sorted by base address, lowest to highest. Usable and bootloader reclaimable entries are guaranteed to be 4096 byte aligned for both base and length. Usable and bootloader reclaimable entries are guaranteed not to overlap with any other entry. To the contrary, all non-usable entries (including executable/modules) are not guaranteed any alignment, nor is it guaranteed that they do not overlap other entries. #### EFI Memory Map Entry Type to Limine Memory Map Type In case the booting firmware is EFI, the following EFI memory map entry types to Limine memory map type are guaranteed to be upheld, unless overridden by any previous rules: * EfiLoaderCode, EfiLoaderData -> `BOOTLOADER_RECLAIMABLE` * EfiBootServicesCode, EfiBootServicesData -> `BOOTLOADER_RECLAIMABLE` * EfiACPIReclaimMemory -> `ACPI_RECLAIMABLE` * EfiACPIMemoryNVS -> `ACPI_NVS` * EfiConventionalMemory -> `USABLE` * [anything else] -> `RESERVED` ### Entry Point Feature ID: ```c #define LIMINE_ENTRY_POINT_REQUEST_ID { LIMINE_COMMON_MAGIC, 0x13d86c035a1cd3e1, 0x2b0caa89d8f3026a } ``` Request: ```c typedef void (*limine_entry_point)(void); struct limine_entry_point_request { uint64_t id[4]; uint64_t revision; struct limine_entry_point_response *response; limine_entry_point entry; }; ``` * `entry` - The requested entry point.

This is honoured if the response is revision 2 or greater. Internal Limine modules are guaranteed to be loaded *before* user-specified (configuration) modules, and thus they are guaranteed to appear before user-specified modules in the `modules` array in the response.

The pixel data consists of *y scanlines of *x pixels, // with each pixel consisting of N interleaved 8-bit components; the first // pixel pointed to is top-left-most in the image. There is no padding between // image scanlines or between pixels, regardless of format. The number of // components N is 'desired_channels' if desired_channels is non-zero, or // *channels_in_file otherwise. If desired_channels is non-zero, // *channels_in_file has the number of components that _would_ have been // output otherwise. E.g. if you set desired_channels to 4, you will always // get RGBA output, but you can check *channels_in_file to see if it's trivially // opaque because e.g. there were only 3 channels in the source image. // // An output image with N components has the following components interleaved // in this order in each pixel: // // N=#comp components // 1 grey // 2 grey, alpha // 3 red, green, blue // 4 red, green, blue, alpha // // If image loading fails for any reason, the return value will be NULL, // and *x, *y, *channels_in_file will be unchanged. The function // stbi_failure_reason() can be queried for an extremely brief, end-user // unfriendly explanation of why the load failed. Define STBI_NO_FAILURE_STRINGS // to avoid compiling these strings at all, and STBI_FAILURE_USERMSG to get slightly // more user-friendly ones. // // Paletted PNG, BMP, GIF, and PIC images are automatically depalettized. // // To query the width, height and component count of an image without having to // decode the full file, you can use the stbi_info family of functions: // // int x,y,n,ok; // ok = stbi_info(filename, &x, &y, &n); // // returns ok=1 and sets x, y, n if image is a supported format, // // 0 otherwise. // // Note that stb_image pervasively uses ints in its public API for sizes, // including sizes of memory buffers. This is now part of the API and thus // hard to change without causing breakage. As a result, the various image // loaders all have certain limits on image size; these differ somewhat // by format but generally boil down to either just under 2GB or just under // 1GB. When the decoded image would be larger than this, stb_image decoding // will fail. // // Additionally, stb_image will reject image files that have any of their // dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, // which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, // the only way to have an image with such dimensions load correctly // is for it to have a rather extreme aspect ratio. Either way, the // assumption here is that such larger images are likely to be malformed // or malicious. If you do need to load an image with individual dimensions // larger than that, and it still fits in the overall size limit, you can // #define STBI_MAX_DIMENSIONS on your own to be something larger. // // =========================================================================== // // UNICODE: // // If compiling for Windows and you wish to use Unicode filenames, compile // with // #define STBI_WINDOWS_UTF8 // and pass utf8-encoded filenames. Call stbi_convert_wchar_to_utf8 to convert // Windows wchar_t filenames to utf8. // // =========================================================================== // // Philosophy // // stb libraries are designed with the following priorities: // // 1. easy to use // 2. easy to maintain // 3. good performance // // Sometimes I let "good performance" creep up in priority over "easy to maintain", // and for best performance I may provide less-easy-to-use APIs that give higher // performance, in addition to the easy-to-use ones. Nevertheless, it's important // to keep in mind that from the standpoint of you, a client of this library, // all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. // // Some secondary priorities arise directly from the first two, some of which // provide more explicit reasons why performance can't be emphasized. // // - Portable ("ease of use") // - Small source code footprint ("easy to maintain") // - No dependencies ("ease of use") // // =========================================================================== // // I/O callbacks // // I/O callbacks allow you to read from arbitrary sources, like packaged // files or some other source. Data read from callbacks are processed // through a small internal buffer (currently 128 bytes) to try to reduce // overhead. // // The three functions you must define are "read" (reads some bytes of data), // "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). // // =========================================================================== // // SIMD support // // The JPEG decoder will try to automatically use SIMD kernels on x86 when // supported by the compiler. For ARM Neon support, you must explicitly // request it. // // (The old do-it-yourself SIMD API is no longer supported in the current // code.) // // On x86, SSE2 will automatically be used when available based on a run-time // test; if not, the generic C versions are used as a fall-back. On ARM targets, // the typical path is to have separate builds for NEON and non-NEON devices // (at least this is true for iOS and Android). Therefore, the NEON support is // toggled by a build flag: define STBI_NEON to get NEON loops. // // If for some reason you do not want to use any of SIMD code, or if // you have issues compiling it, you can disable it entirely by // defining STBI_NO_SIMD. // // =========================================================================== // // HDR image support (disable by defining STBI_NO_HDR) // // stb_image supports loading HDR images in general, and currently the Radiance // .HDR file format specifically. You can still load any file through the existing // interface; if you attempt to load an HDR file, it will be automatically remapped // to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; // both of these constants can be reconfigured through this interface: // // stbi_hdr_to_ldr_gamma(2.2f); // stbi_hdr_to_ldr_scale(1.0f); // // (note, do not use _inverse_ constants; stbi_image will invert them // appropriately). // // Additionally, there is a new, parallel interface for loading files as // (linear) floats to preserve the full dynamic range: // // float *data = stbi_loadf(filename, &x, &y, &n, 0); // // If you load LDR images through this interface, those images will // be promoted to floating point values, run through the inverse of // constants corresponding to the above: // // stbi_ldr_to_hdr_scale(1.0f); // stbi_ldr_to_hdr_gamma(2.2f); // // Finally, given a filename (or an open file or memory block--see header // file for details) containing image data, you can query for the "most // appropriate" interface to use (that is, whether the image is HDR or // not), using: // // stbi_is_hdr(char *filename); // // =========================================================================== // // iPhone PNG support: // // We optionally support converting iPhone-formatted PNGs (which store // premultiplied BGRA) back to RGB, even though they're internally encoded // differently. To enable this conversion, call // stbi_convert_iphone_png_to_rgb(1). // // Call stbi_set_unpremultiply_on_load(1) as well to force a divide per // pixel to remove any premultiplied alpha *only* if the image file explicitly // says there's premultiplied data (currently only happens in iPhone images, // and only if iPhone convert-to-rgb processing is on). // // =========================================================================== // // ADDITIONAL CONFIGURATION // // - You can suppress implementation of any of the decoders to reduce // your code footprint by #defining one or more of the following // symbols before creating the implementation. // // STBI_NO_JPEG // STBI_NO_PNG // STBI_NO_BMP // STBI_NO_PSD // STBI_NO_TGA // STBI_NO_GIF // STBI_NO_HDR // STBI_NO_PIC // STBI_NO_PNM (.ppm and .pgm) // // - You can request *only* certain decoders and suppress all other ones // (this will be more forward-compatible, as addition of new decoders // doesn't require you to disable them explicitly): // // STBI_ONLY_JPEG // STBI_ONLY_PNG // STBI_ONLY_BMP // STBI_ONLY_PSD // STBI_ONLY_TGA // STBI_ONLY_GIF // STBI_ONLY_HDR // STBI_ONLY_PIC // STBI_ONLY_PNM (.ppm and .pgm) // // - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still // want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB // // - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater // than that size (in either width or height) without further processing. // This is to let programs in the wild set an upper bound to prevent // denial-of-service attacks on untrusted data, as one could generate a // valid image of gigantic dimensions and force stb_image to allocate a // huge block of memory and spend disproportionate time decoding it.

inside > ${PREFIX}/share/, installed there as a product of the steps described in > [INSTALL.md](INSTALL.md). ## UEFI The `BOOT*.EFI` files are valid EFI applications that can be simply copied to the `/EFI/BOOT` directory of a FAT formatted EFI system partition. These files can be installed there and coexist with a BIOS installation of Limine (see below) so that the disk will be bootable on both BIOS and UEFI systems. A valid config file should also be provided as described in [CONFIG.md](CONFIG.md). ## Secure Boot Limine can be booted with secure boot if the executable is signed and the key used to sign it is added to the firmware's keychain. This should be done in combination with enrolling the BLAKE2B hash of the Limine config file into the Limine EFI executable image itself for verification purposes. For more information see the `limine enroll-config` program and [the FAQ](FAQ.md). ## BIOS/MBR In order to install Limine on a MBR device (which can just be a raw image file), run `limine bios-install` as such: ```bash limine bios-install ``` The boot device must contain the `limine-bios.sys` and `limine.conf` files in either a `boot/limine`, `boot`, `limine`, or root directory of one of the partitions, formatted with a supported file system. See [CONFIG.md](CONFIG.md). ## BIOS/GPT If using a GPT formatted device, create a partition on the GPT device (usually of "BIOS boot" type) of at least 32KiB in size, and pass the 1-based number of the partition to `limine bios-install` as a second argument; such as: ```bash limine bios-install <1-based stage 2 partition number> ``` The boot device must contain the `limine-bios.sys` and `limine.conf` files in either a `boot/limine`, `boot`, `limine`, or root directory of one of the partitions, formatted with a supported file system. See [CONFIG.md](CONFIG.md). ## BIOS/UEFI hybrid ISO creation In order to create a hybrid ISO with Limine, place the `limine-uefi-cd.bin`, `limine-bios-cd.bin`, `limine-bios.sys`, and `limine.conf` files into a directory which will serve as the root of the created ISO. (`limine-bios.sys` and `limine.conf` must either be in the root, `limine`, `boot`, or `boot/limine` directory; `limine-uefi-cd.bin` and `limine-bios-cd.bin` can reside anywhere). After that, create a `/EFI/BOOT` directory and copy the relevant Limine EFI executables over (such as `BOOTX64.EFI`). Place any other file you want to be on the final ISO in said directory, then run: ``` xorriso -as mkisofs -R -r -J -b \ -no-emul-boot -boot-load-size 4 -boot-info-table -hfsplus \ -apm-block-size 2048 --efi-boot \ -efi-boot-part --efi-boot-image --protective-msdos-label \ -o image.iso ``` *Note: `xorriso` is required.* And do not forget to also run `limine bios-install` on the generated image: ``` limine bios-install image.iso ``` `` is the relative path of `limine-bios-cd.bin` inside the root directory. For example, if it was copied in `/boot/limine-bios-cd.bin`, it would be `boot/limine-bios-cd.bin`. `` is the relative path of `limine-uefi-cd.bin` inside the root directory. For example, if it was copied in `/boot/limine-uefi-cd.bin`, it would be `boot/limine-uefi-cd.bin`. ## BIOS/PXE boot The `limine-bios-pxe.bin` binary is a valid PXE boot image. In order to boot Limine from PXE it is necessary to setup a DHCP server with support for PXE booting. This can either be accomplished using a single DHCP server or your existing DHCP server and a proxy DHCP server such as dnsmasq. `limine.conf` and `limine-bios.sys` are expected to be on the server used for boot. ## UEFI/PXE boot The `BOOT*.EFI` files are compatible with UEFI PXE. The steps needed to boot Limine are the same as with BIOS PXE, except that the `limine-bios.sys` file is not needed on the server. ## Configuration The `limine.conf` file contains Limine's configuration. More info on the format of `limine.conf` can be found in [`CONFIG.md`](CONFIG.md). limine-10.3.0/LICENSES/0000755000000000000000000000000015103344043012750 5ustar rootrootlimine-10.3.0/LICENSES/LicenseRef-scancode-bsd-no-disclaimer-unmodified.txt0000644000000000000000000000066515103344043024727 0ustar rootroot * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

Furthermore, `gcc` or `llvm/clang` must also be installed, alongside the respective binutils. ## Configure If using a release tarball (recommended, see https://codeberg.org/Limine/Limine/releases), run `./configure` directly. If checking out from the repository, run `./bootstrap` first in order to download the necessary [dependencies](3RDPARTY.md) and generate the configure script (`GNU autoconf` required). `./configure` takes arguments and environment variables; for more information on these, run `./configure --help`. > **NOTE:** `./configure` by default does not build any Limine port. Make sure > to read the output of `./configure --help` and enable any or all ports! Limine supports both in-tree and out-of-tree builds. Simply run the `configure` script from the directory you wish to execute the build in. The following `make` commands are supposed to be run inside the build directory. ## Building To build Limine, run: ```bash make # (or gmake where applicable) ``` ## Installing This step will install Limine files to `share`, `include`, and `bin` directories in the specified prefix (default is `/usr/local`, see `./configure --help`. To install Limine, run: ```bash make install # (or gmake where applicable) ``` limine-10.3.0/GNUmakefile.in0000644000000000000000000004353115103344043014230 0ustar rootroot.SUFFIXES: override

limine-10.3.0/FAQ.md0000644000000000000000000000346215103344043012501 0ustar rootroot# Frequently Asked Questions ### Why not support filesystem X or feature Y? (eg: LUKS, LVM) The idea with Limine is to remove the responsibility of parsing filesystems and formats, aside from the bare minimum necessities (eg: FAT*, ISO9660), from the bootloader itself. It is a needless duplication of efforts to have bootloaders support all possible filesystems and formats, and it leads to massive, bloated bootloaders as a result (eg: GRUB2). What is needed is to simply make sure the bootloader is capable of reading its own files, configuration, and be able to load kernel/module files from disk. The kernel should be responsible for parsing everything else as it sees fit. ### What about LUKS? What about security? Encrypt the kernel! Simply put, this is unnecessary. Putting the kernel/modules in a readable FAT32 partition and letting Limine know about their BLAKE2B checksums in the config file provides as much security as encrypting the kernel does. ### What if a malicious actor modifies the config file? While this is a pointless effort on legacy x86 BIOS, it is a reasonable expectation to secure the boot sequence on UEFI systems with Secure Boot. Limine provides a way to modify its own EFI executable to bake in the BLAKE2B checksum of the config file itself. The EFI executable can then get signed with a key added to the firmware's keychain. This prevents modifications to the config file (and in turn the checksums contained there) from going unnoticed. ### I do not want to have a separate FAT boot partition! What can I do? It is `$year_following_2012` now and most PCs are equipped with UEFI and simply won't boot without a FAT EFI system partition anyways. It is not unreasonable to share the EFI system partition with the OS's /boot and store kernels, initramfses, and any other files needed for boot there. limine-10.3.0/ChangeLog0000644000000000000000000014551315103344043013326 0ustar rootroot2025-11-07 Mintsuki *** Release 10.3.0 *** Noteworthy changes compared to the previous release, 10.2.1: **Special notes:** Despite there being breaking changes in this release, no major version bump is done; this is because the changes are minor enough, there are no big new features, and version 10.x was not released long enough ago. This is technically in violation of Semantic Versioning, but considered to be an acceptable exception. Breaking changes: - Change default paths and default path ordering for configuration file search. Mainly, search first for a configuration file in the same directory as the EFI application file of Limine, on EFI ports. - Change default path ordering for stage 3 file search on BIOS ports. - No longer install the limine.h header file on the host. - No longer install PROTOCOL.md (Limine Boot Protocol specification) on the host. Bug fixes: - Fix an issue where code assumed that the RSDT address in the RSDP was always non-NULL, which could cause crashes or hangs when using base revision 4 of the Limine Boot Protocol. 2025-10-29 Mintsuki *** Release 10.2.1 *** Noteworthy changes compared to the previous release, 10.2.0: Bug fixes: - Add workaround for skipping SPI flash devices exposed as EFI volumes. This fixes the hanging issues on many ARM laptops, without breaking U-Boot unlike the previous workaround. 2025-10-26 Mintsuki *** Release 10.2.0 *** Noteworthy changes compared to the previous release, 10.1.1: New features: - Implement base revision 4 of the Limine boot protocol as per documentation (read documentation for specific details). Bug fixes: - "Fix" multiboot1 framebuffer structure to match GRUB instead of the multiboot1 specification. 2025-10-13 Mintsuki *** Release 10.1.1 *** Noteworthy changes compared to the previous release, 10.1.0: Bug fixes: - DTBs: Always reallocate DTBs to bootloader-reclaimable memory. This is to prevent pointers to EFI/reserved memory from being leaked to Limine protocol executables, which is against said protocol, which mandates that DTBs have to be in bootloader-reclaimable memory. 2025-10-05 Mintsuki *** Release 10.1.0 *** Noteworthy changes compared to the previous release, 10.0.1: New features: - Expand safety checks of the `limine bios-install` command and replace the `--force-mbr` flag with just `--force`. - Add autodetection of the BIOS boot partition if no explicit partition index is passed to `limine bios-install`. Bug fixes: - Only use ASCII characters for terminal output when graphical output fails to initialise and the EFI standard output console is used instead. Miscellaneous: - Remove left-over logic that was meant to supplement the removed GPT embedding feature. - Remove workaround to allow building the RISC-V port with LLVM <=16. - Update a bunch of output messages from the `limine` host tool. 2025-09-21 Mintsuki *** Release 10.0.1 *** Noteworthy changes compared to the previous release, 10.0.0: Bug fixes: - Fix a potential use-after-free issue when flushing interrupts on x86 UEFI systems. - Prefer using the 32-bit Linux protocol unless it is strictly necessary to use the 64-bit protocol due to allocation constraints. This is due to reports of the 32-bit protocol being more reliable on certain rare systems where the 64-bit protocol crashes or hangs. 2025-09-15 Mintsuki *** Release 10.0.0 *** Noteworthy changes compared to the previous release, 9.6.7: Breaking changes: - GPT embedding is no longer supported as a deployment method for GPT-with-BIOS configurations. The rationale for this being that it is far too fragile, especially with regards to growing or shrinking disk images, and it may cause certain machines to refuse to boot such setups as they are technically in violation of the GPT specification. - The default baud rate for serial I/O on BIOS systems is now 115200, instead of 9600. - BIOS (chainloading) boot menu entries are now hidden when booting in UEFI mode, and EFI (chainloading) entries are hidden when booting in BIOS mode. - For the Limine boot protocol, for relocatable executables, KASLR now defaults to being disabled. The rationale for this being that KASLR is a somewhat niche and fairly bypassable security technique, which can cause headaches for kernels not wanting to support it, and make troubleshooting harder. - For the Limine boot protocol, for PE format kernels, do not discard discardable sections, as code put to a discardable section like INIT might be intended to only be discarded after early kernel init, not before the kernel is even loaded. 2025-09-13 Mintsuki *** Release 9.6.7 *** Noteworthy changes compared to the previous release, 9.6.6: Bug fixes: - Relax EFI handle validation before running fallback volume detection. This further addresses issues caused by 9.5.4. 2025-09-06 Mintsuki *** Release 9.6.6 *** Noteworthy changes compared to the previous release, 9.6.5: Bug fixes: - Fix regression introduced by 9.5.4 that caused Limine to fail to boot with U-Boot. 2025-08-30 Mintsuki *** Release 9.6.3 through 9.6.5 *** Noteworthy changes compared to the previous release, 9.6.2: These are special hotfix releases attempting to address issues with the Forgejo release workflow after the migration to Codeberg. Other than that, they have no differences compared to 9.6.2. 2025-08-30 Mintsuki *** Release 9.6.2 *** Noteworthy changes compared to the previous release, 9.6.1: Miscellaneous: - The Limine project has moved its home to Codeberg. - Nyu-EFI was rebranded to PicoEFI. - Minor build system improvements and subproject bumps. 2025-08-16 Mintsuki *** Release 9.6.1 *** Noteworthy changes compared to the previous release, 9.6.0: Bug fixes: - EFI chainloading: Make EFI device path of loaded image relative to the loaded image device handle. This now complies with the EFI specification, and, amongst others, it fixes chainloading Shim. Miscellaneous: - Miscellaneous build system changes and improvements. - Do not disable linker relaxations for LoongArch64. - `limine` host tool: Add check to ensure that a provided GPT BIOS partition is at least 32KiB in size. 2025-08-07 Mintsuki *** Release 9.6.0 *** Noteworthy changes compared to the previous release, 9.5.4: Miscellaneous: - Get rid of the fragile and messy "freestanding-toolchain" build helper tool. This allows for a simpler and more predictable way of selecting the target toolchain components via ./configure. 2025-08-06 Mintsuki *** Release 9.5.4 *** Noteworthy changes compared to the previous release, 9.5.3: Bug fixes: - Exclude non-PCI devices from the volume discovery process on UEFI. This is because on (especially, but not limited to) Snapdragon X systems, firmware/flash devices, which are non-PCI, are exposed as block I/O volumes too. This skips them, which makes the bootloader more reliable and avoids long hangs at boot. - Miscellaneous changes and fixes to the fallback volume discovery path, to increase reliability and reduce the chance of accidental damage or data loss. See GitHub issue #525. - Minor assembly improvement that fixed Limine not building with old NASM. 2025-08-04 Mintsuki *** Release 9.5.3 *** Noteworthy changes compared to the previous release, 9.5.2: Bug fixes: - Miscellaneous build system fixes, mainly to sort out possible issues introduced by 9.5.2. 2025-08-01 Mintsuki *** Release 9.5.2 *** Noteworthy changes compared to the previous release, 9.5.1: Bug fixes: - Revert change that moved to `nm` from `objdump` for generating the symbol table, as that broke section-specific symbol dumps and caused BIOS stage 2 to be bloated with the full symbol table. Miscellaneous: - Miscellaneous build system updates and improvements. 2025-07-29 Mintsuki *** Release 9.5.1 *** Noteworthy changes compared to the previous release, 9.5.0: Bug fixes: - Unbreak build using ld.gold as linker. Miscellaneous: - Miscellaneous build system updates and improvements. 2025-07-14 Mintsuki *** Release 9.5.0 *** Noteworthy changes compared to the previous release, 9.4.0: New features: - protocols/efi: Hybridise loading mechanism with old memory-device based approach. This may work around the redundant requirement that EFI applications be signed, and it may fix certain issues created when the chainload mechanism was changed in 9.0.1. Bug fixes: - `limine` host tool: Fix some mismatched printf format specifiers. Miscellaneous: - Miscellaneous build system updates and improvements. - Many dependencies had their commits bumped, some new dependencies were added (limine-protocol), some were changed (libfdt moved to a different repository that only includes BSD-2-Clause licensable code). 2025-07-10 Mintsuki *** Release 9.4.0 *** Noteworthy changes compared to the previous release, 9.3.4: New features: - BLI: Implement `LoaderTimeInitUSec` and `LoaderTimeExecUSec`. These are variables used by `systemd-analyze` and are useful for boot performance metrics. - Limine boot protocol: Add bootloader performance feature. This feature provides the same information as the new Boot Loader Interface variables, but encoded in a nicer way for Limine protocol executables. Miscellaneous: - Use `nm` instead of `objdump` for generating the symbol table, which results in a better, more consistent output, especially for non-x86 architectures. - Miscellaneous build system updates and improvements. 2025-06-21 Mintsuki *** Release 9.3.4 *** Noteworthy changes compared to the previous release, 9.3.3: Bug fixes: - ELF: Make an optimisation related to skipping scanning of .bss regions for finding of structures in the loaded image (for Limine protocol structures or otherwise) less overeager as that could break in certain cases. - SMP: On x86, ensure that the value of IA32_APIC_BASE is the same on the APs as it is on the BSP. - PMM: Mark EfiLoader{Code,Data} regions as bootloader reclaimable rather than reserved memory, as for certain protocols, like the Limine boot protocol, reserved memory is unmapped at runtime, while these regions may contain hot data that is still needed, like Limine bootloader memory stacks. 2025-05-27 Mintsuki *** Release 9.3.3 *** Noteworthy changes compared to the previous release, 9.3.2: Bug fixes: - Reinstate the limit for scanned drives to 0xf0. This is due to a report of int 13h hangs when used on drives >=0xf0. 2025-05-19 Mintsuki *** Release 9.3.2 *** Noteworthy changes compared to the previous release, 9.3.1: Bug fixes: - PMM: Mark EfiBootServices{Code,Data} memory regions as bootloader reclaimable instead of usable free memory as apparently the ACPI and UEFI specifications make no guarantees about useful structures being left in these areas after leaving boot services (namely BGRT and ESRT). 2025-05-15 Mintsuki *** Release 9.3.1 *** Noteworthy changes compared to the previous release, 9.3.0: Bug fixes: - Remove .git directory mistakenly left over inside release tarballs. - Fix bug that would lead to panics when booting Linux protocol kernels without modules on x86. 2025-05-07 Mintsuki *** Release 9.3.0 *** Noteworthy changes compared to the previous release, 9.2.3: New features: - Add optional support for the 64-bit x86-64 boot protocol for Linux. This is supported on the UEFI/x86-64 port of Limine, and it is preferred over the 32-bit boot protocol if supported by the given kernel. This helps with loading larger modules on certain systems with low amounts of low memory which would otherwise panic. Bug fixes: - Fix away some ungraceful handling of out-of-memory situations when loading files using the Linux boot protocol. Make into panics instead of crashes or hangs. Miscellaneous: - Improve performance and memory usage of loading modules for the Linux boot protocol. 2025-04-12 Mintsuki *** Release 9.2.3 *** Noteworthy changes compared to the previous release, 9.2.2: Bug fixes: - Fix issues introduced by the stb_image fix introduced in 9.2.1 which could cause hangs or crashes when certain wallpaper images are used. Miscellaneous: - Update cc-runtime to new, integer-only, packed version. 2025-03-31 Mintsuki *** Release 9.2.2 *** Noteworthy changes compared to the previous release, 9.2.1: Bug fixes: - Two quick bug fixes and workarounds in order to make multiboot2 more resilient when booting specific kernels such as Xen. - Avoid mistakenly allocating more memory than necessary when creating the volume index. 2025-03-25 Mintsuki *** Release 9.2.1 *** Noteworthy changes compared to the previous release, 9.2.0: Bug fixes: - Fix potential buffer overflow bug with our stb_image support code. Miscellaneous: - Dynamically allocate volume index instead of relying on a hard coded limit and a fixed allocation. This fixes potential panics or failure to access volumes on systems with a lot of drives/partitions. - Limine boot protocol/ELF: Print the name of unresolved symbols on panic. 2025-03-16 Mintsuki *** Release 9.2.0 *** Noteworthy changes compared to the previous release, 9.1.3: New features: - Introduce initial support for the Boot Loader Interface specification. - Add /EFI/limine/limine.conf to the paths tried for config file when using EFI. Miscellaneous: - Do not try config path /EFI/BOOT/limine.conf unless booted using EFI. 2025-03-13 Mintsuki *** Release 9.1.3 *** Noteworthy changes compared to the previous release, 9.1.2: Bug fixes: - Loongarch64: Fix alignment of TLB-refill handler. Miscellaneous: - Many fixes and improvements to documentation, installed or otherwise, including further licensing clarifications. 2025-03-11 Mintsuki *** Release 9.1.2 *** Noteworthy changes compared to the previous release, 9.1.1: This release does not change anything code-wise, but rather it focuses on sorting out the licensing mess of Nyu-EFI, by updating it to the latest revision which tackles this problem, and furthermore it improves the COPYING file to be more explicit about submodules and their licensing. 2025-03-10 Mintsuki *** Release 9.1.1 *** Noteworthy changes compared to the previous release, 9.1.0: Bug fixes: - Do not use ConOut for serial output exclusively unless serial is verified to be present to the best of our abilities. This fixes an issue where if `serial=yes` is used on some machines (including several Apple Mac models) a black screen will be shown instead of the Limine menu. Miscellaneous: - Begin signing tarballs and (most) commits. 2025-03-07 Mintsuki *** Release 9.1.0 *** Noteworthy changes compared to the previous release, 9.0.1: New features: - `limine` host tool: When using the `bios-install` command on an ISOHYBRID with a GPT, automatically convert it to MBR, if possible and unless explicitly disabled, in order to enhance compatibility of said ISOHYBRIDs with many systems (of note, Lenovo Thinkpads). 2025-02-25 Mintsuki *** Release 9.0.1 *** Noteworthy changes compared to the previous release, 9.0.0: Miscellaneous: - EFI chainload: Replace old chainload method with one that is more friendly to other EFI bootloaders such as rEFInd. - Limine boot protocol/PE: Map previously unmapped PE image headers. 2025-02-17 Mintsuki *** Release 9.0.0 *** Noteworthy changes compared to the previous release, 8.7.0: Breaking changes: - Support for the ext2/3/4 filesystems has been once again dropped due to lack of maintenance and to avoid extra potential attack surface during Secure Boot Limine usage. - Drop support for the legacy config format (limine.cfg) and only keep around the new one (limine.conf) introduced with Limine 8.x. - Drop support for the (barely worked and seldom used) `chainload_next` protocol. New features: - Limine boot protocol: Introduce API revision 3, for the `limine.h` file with several renamed identifiers for better clarity. - Limine boot protocol: Specify and implement a new, convenience, "Executable Command Line feature". - Limine boot protocol: Use monitor/mwait CPU instructions, when available, to reduce CPU usage and increase performance during multiprocessor initialisation. - Add preferred aliases for BIOS and EFI chainload (namely `bios` and `efi`) protocol names for the `protocol` config option. Bug fixes: - EFI (chainload) boot protocol: Fix `path` option alias not working. Miscellaneous: - Update Flanterm submodule to latest. 2025-01-10 Mintsuki *** Release 8.7.0 *** Noteworthy changes compared to the previous release, 8.6.1: New features: - Limine boot protocol: Add support for PE executables. - Linux boot protocol: Enable support for Loongarch64. - Add support for selecting a random wallpaper every boot if multiple are provided. - Add `path` aliases for `kernel_path` and `image_path` for the Linux and EFI Chainloading protocols respectively. Miscellaneous: - Submodule version/commit bumps. 2024-12-26 Mintsuki *** Release 8.6.1 *** Noteworthy changes compared to the previous release, 8.6.0: Bug fixes: - Propagate EFI PXE device handle properly when chainloading. - Ensure that, when specifying a `dtb_path`, extra space is properly allocated just as is done for EFI-provided DTBs. Miscellaneous: - Linux on RISCs: General code clean up; pass EFI memory map and initrd information as EFI configuration tables alongside already passed DTB parameters for the same, in preparation for loongarch64 support. 2024-12-05 Mintsuki *** Release 8.6.0 *** Noteworthy changes compared to the previous release, 8.5.0: New features: - Limine boot protocol: Specify and implement new "RISC-V BSP Hart ID" feature. - Limine boot protocol: Add a new "SBI" firmware type to the firmware type feature - Limine boot protocol: Add a new API revision 2 to the limine.h header file. This replaces many mentions of 'kernel' with a more neutral 'executable' instead. - Config: add 'path' alias for 'kernel_path' for the Limine and multiboot1 and 2 protocols. 2024-11-30 Mintsuki *** Release 8.5.0 *** Noteworthy changes compared to the previous release, 8.4.1: New features: - Limine boot protocol: Introduce limine.h API revisions to avoid API breaks. Bug fixes: - Limine boot protocol: Amend base revision 3 to keep EFI memmap pointer as virtual. Making it physical made no sense and is henceforth considered a bug. Miscellaneous: - Limine boot protocol: Rename SMP feature to MP feature for limine.h API revision 1+. - Limine boot protocol: Make some types that were void pointers into uint64_t's to better represent their physical nature; limine.h API revision 1+. 2024-11-25 Mintsuki *** Release 8.4.1 *** Noteworthy changes compared to the previous release, 8.4.0: Miscellaneous: - Limine boot protocol: Ensure machines with pre-enabled x2APIC are properly supported. - Reuse a viable framebuffer for UEFI fallback terminal output (like on panics) if boot services have been exited instead of bailing out. - Miscellaneous build system updates. 2024-11-08 Mintsuki *** Release 8.4.0 *** Noteworthy changes compared to the previous release, 8.3.2: New features: - Support passing Limine its configuration via SMBIOS tables.

Miscellaneous: - Documentation: USAGE.md: Update `xorriso` command to produce ISOHYBRIDs with Joliet info and an HFS+ filesystem for broader compatibility. - Increase the size of the `limine-cd-uefi.bin` image to 5760 sectors; this allows more and/or larger EFI executables to fit (like for example those generated when compiling with -O0). - Bump cc-runtime revision to d5425655388977fa12ff9b903e554a20b20c426e. 2024-10-15 Mintsuki *** Release 8.1.2 *** Noteworthy changes compared to the previous release, 8.1.1: Bug fixes: - Add missing register saves and restores around call from assembly to C code for the x86-64 UEFI port. This bug could have caused crashes with certain compiler optimisation levels (like -O0). - Adjust size of reserved area of VBE mode info struct to be the right size. This bug could have caused crashes with certain compiler optimisation levels (like -O0). - Ignore UEFI memory map entries of length 0. This fixes crashes that could have happened on quirky UEFI firmwares passing such entries. 2024-10-12 Mintsuki *** Release 8.1.1 *** Noteworthy changes compared to the previous release, 8.1.0: Bug fixes: - Limine boot protocol: Do not hard depend on the CPU supporting the Page Attribute Table (PAT) *for SMP processors as well*. 2024-10-12 Mintsuki *** Release 8.1.0 *** Noteworthy changes compared to the previous release, 8.0.14: Bug fixes: - Limine boot protocol: Do not hard depend on the CPU supporting the Page Attribute Table (PAT).

This ensures that certain relocatable ELF files that were previously misidentified as non-relocatable are recognised as such. 2024-05-22 Mintsuki *** Release 7.5.2 *** Noteworthy changes compared to the previous release, 7.5.1: Bug fixes: - Fix missing checks in the FAT filesystem driver that could cause divide-by-0 exceptions when parsing malformed/corrupted filesystems. - Limine boot protocol: Do not reject relocatable kernels with ELF PHDR load addresses at or around 0, instead slide them all the way to the topmost 2GiB (0xffffffff80000000). This allows setting a base load address of 0 in LD BFD/LLD linker scripts which makes LD BFD (the default GNU LD) actually emit an ELF with ET_DYN type. 2024-05-08 Mintsuki *** Release 7.5.1 *** Noteworthy changes compared to the previous release, 7.5.0: Bug fixes: - Workarounds for issues related to drive iteration on BIOS. Discovered on an HP Pavilion dv6-3152er. 2024-05-03 Mintsuki *** Release 7.5.0 *** Noteworthy changes compared to the previous release, 7.4.1: New features: - Limine boot protocol: Add support for requests start marker, to complement the previously called delimiter, now renamed to "end marker". - Limine boot protocol: Add base revision 2. The sole difference compared to base revision 1 being that it mandates bootloaders to support request delimiters. Bug fixes: - Fix an issue regarding commit date parsing in the bootstrap script. Miscellaneous: - General documentation updates and improvements; split USAGE.md from README.md and install the former only. 2024-04-29 Mintsuki *** Release 7.4.1 *** Noteworthy changes compared to the previous release, 7.4.0: Miscellaneous: - Bump max volume limit for UEFI from 64 to 256. - Improve how ISA name and firmware type is reported as part of the default branding. 2024-04-20 Mintsuki *** Release 7.4.0 *** Noteworthy changes compared to the previous release, 7.3.1: New features: - ISA name and firmware type is now printed as part of the default bootloader branding. - Add 'B' key shortcut to menu to open up a blank entry. Bug fixes: - Fix missing NULL pointer check in configuration related function. Miscellaneous: - Console has been removed. 2024-04-11 Mintsuki *** Release 7.3.1 *** Noteworthy changes compared to the previous release, 7.3.0: Bug fixes: - Fix a minor issue with scrolling when using the EFI console fallback. Miscellaneous: - Bump the Flanterm revision to current latest. - Some dead code removal. 2024-03-31 Mintsuki *** Release 7.3.0 *** Noteworthy changes compared to the previous release, 7.2.1: New features: - Limine boot protocol: Add a `MAX_PAGING_MODE` configuration option to override kernel/bootloader selected paging mode. Bug fixes: - Fix a couple of minor bugs with the 4GiB workaround introduced in version 7.2.1. Miscellaneous: - No longer produce xz compressed release tarballs. Add bzip2, lzip, and zstd as alternatives in its place. 2024-03-28 Mintsuki *** Release 7.2.1 *** Noteworthy changes compared to the previous release, 7.2.0: Bug fixes: - Implement workaround to allow Limine loaded above 4GiB by UEFI on x86-64 to work in some configurations, instead of panicking. 2024-03-24 Mintsuki *** Release 7.2.0 *** Noteworthy changes compared to the previous release, 7.1.0: New features: - Add support for remembering the last booted entry on UEFI by means of the `REMEMBER_LAST_ENTRY` config option. 2024-03-19 Mintsuki *** Release 7.1.0 *** Noteworthy changes compared to the previous release, 7.0.5: New features: - Limine boot protocol: Add support for requests delimiter. Bug fixes: - Fixed a potential security vulnerability in the ISO9660 driver. 2024-02-15 Mintsuki *** Release 7.0.5 *** Noteworthy changes compared to the previous release, 7.0.4: Bug fixes: - Build system related fixes and improvements. This fixes an issue that caused Limine 7.0.4 to fail building on Busybox systems. 2024-02-14 Mintsuki *** Release 7.0.4 *** Noteworthy changes compared to the previous release, 7.0.3: Bug fixes: - Minor build system related fixes and improvements. Miscellaneous: - Significantly improve reproducibility of builds. 2024-02-08 Mintsuki *** Release 7.0.3 *** Noteworthy changes compared to the previous release, 7.0.2: Bug fixes: - multiboot2 protocol: Do not panic if there is a ENTRY_ADDRESS_EFI64 tag, but there is a valid alternative entry point. This further aligns our behaviour with GRUB2. Miscellaneous: - Terminal: Significantly improve serial and fallback UEFI console's rendition (especially colour palettes). - Serial: Add a baud rate config setting for Limine's BIOS version. 2024-01-26 Mintsuki *** Release 7.0.2 *** Noteworthy changes compared to the previous release, 7.0.1: Bug fixes: - Fix a cosmetic bug in the menu where, when the editor was disabled, the controls showed "ENTER Expand" even for boot entries instead of only for menu directories. Miscellaneous: - Exclusively use git for obtaining dependencies in "bootstrap" script. 2024-01-22 Mintsuki *** Release 7.0.1 *** Noteworthy changes compared to the previous release, 7.0.0: Bug fixes: - Fix ARM64/aarch64 spinup code to properly support Apple Silicon chips. - Prevent users from building Limine with a GNU Make version older than 4.2, as that is not supported, by gracefully erroring out with a useful error message. - Avoid usage of reserved C identifiers in certain cases. Miscellaneous: - Drop usage of "libgcc-binaries" for "cc-runtime". This finally makes us able to ship Limine tarballs without included binary blobs, and should improve compatibility with more obscure toolchain set ups. 2024-01-14 Mintsuki *** Release 7.0.0 *** Noteworthy changes compared to the previous release, 6.20240107.0: Bug fixes: - Minor fix of newline handling when reading user input lines. Miscellaneous: - Bump major version to 7. Note: There is no breaking change in 7.x compared to 6.x; the major version bump is done due to a change in the versioning scheme used by Limine (move to proper Semantic Versioning). - Fix versions of external dependencies in "bootstrap" script. 2024-01-07 Mintsuki *** Release 6.20240107.0 *** Noteworthy changes compared to the previous release, 6.20231227.0: New features: - Limine boot protocol: Add support for compressed internal modules. Miscellaneous: - Improve error reporting from host "limine" executable. - Track "master" branch of stb_image upstream. 2023-12-27 Mintsuki *** Release 6.20231227.0 *** Noteworthy changes compared to the previous release, 6.20231226.0: Bug fixes: - Actually regenerate build system with GNU Autoconf 2.72 instead of GNU Autoconf 2.71. 2023-12-26 Mintsuki *** Release 6.20231226.0 *** Noteworthy changes compared to the previous release, 6.20231216.0: New features: - Ignore trailing whitespace in Limine config file.

On BIOS, or on EFI if that file is not found, Limine scans for the config file on *the boot drive*. Every partition of the boot drive is scanned sequentially - first partition first (or, on EFI, the partition containing the EFI executable of the booted Limine is scanned first), last partition last - for the presence of either a `/boot/limine/limine.conf`, `/boot/limine.conf`, `/limine/limine.conf`, or a `/limine.conf` file, in that order. Once the file is located, Limine will use it as its config file. Other possible candidates in subsequent partitions or directories are ignored. It is thus imperative that the intended config file is placed in a location that will not be shadowed by another candidate config file. ### Config via SMBIOS Alternatively, if present, Limine considers first and foremost configurations supplied to it as SMBIOS OEM String entries (Type 11). Such configurations are accepted if the first string of such an entry starts with the prefix of `limine:config:`. The rest of the string is taken as the config file. If such a configuration is found, no further scanning for config files is done. As such, in this SMBIOS-provided config file scenario, the `boot():` drive is undefined on BIOS, and set to the boot device of Limine on UEFI. ## Structure of the config file The Limine configuration file is comprised of *menu entries* and *options*. Comments begin in '#' and can only be on their own lines. ### Menu entries and sub-entries *Menu entries* describe *entries* which the user can select in the *boot menu*. A *menu entry* is opened by a line starting with `/` followed by a newline-terminated string, that being the title of the entry which the user will see. Any *local option* that comes after it, and before another *menu entry*, or the end of the file, will be part of that *menu entry*. A *menu entry* can be a directory, meaning it can hold sub-entries. In order for an entry to become a directory, it needs to have a sub-entry following right after it. (A `comment` option may be present between the beginning of the directory entry and the beginning of the sub-entry). A *sub-entry* is a menu entry started with a number of `/` greater than 1 prepended to it. Each `/` represents 1 level deeper down the tree hierarchy of directories and entries. Directories can be expanded (meaning they will not show up as collapsed in the menu) by default if a `+` is put between the `/`s and the beginning of the entry's title. ### Options *Options* are simple `option_name: string...` style "assignments". The string can have spaces and other special characters, without requiring quotations. New lines are delimiters. Option names are not case sensitive. Some *options* are part of an entry (*local*), some other options are *global*. *Global options* can appear anywhere in the file and are not part of an entry, although usually one would put them at the beginning of the config. Some *local options* work the same between entries using any *protocol*, while other *local options* are specific to a given *protocol*. Some options take *paths* as strings; these are described in the next section. *Global options* are: Miscellaneous: * `timeout` - Specifies the timeout in seconds before the first *entry* is automatically booted. If set to `no`, disable automatic boot. If set to `0`, boots default entry instantly (see `default_entry` option). * `quiet` - If set to `yes`, enable quiet mode, where all screen output except panics and important warnings is suppressed. If `timeout` is not 0, the `timeout` still occurs, and pressing any key during the timeout will reveal the menu and disable quiet mode. * `serial` - If set to `yes`, enable serial I/O for the bootloader. * `serial_baudrate` - If `serial` is set to `yes`, this specifies the baudrate to use for serial I/O. Defaults to `115200`. BIOS only, ignored with Limine UEFI. * `default_entry` - 1-based entry index of the entry which will be automatically selected at startup. If unspecified, it is `1`. * `remember_last_entry` - If set to `yes`, remember last booted entry. (UEFI only). * `graphics` - If set to `no`, force CGA text mode for the boot menu, else use a video mode. Ignored with Limine UEFI. * `wallpaper` - Path to a file to use as a wallpaper. BMP, PNG, and JPEG formats are supported. There can be multiple of this option, in which case the wallpaper will be randomly selected from the provided options. * `wallpaper_style` - The style which will be used to display the wallpaper image: `tiled`, `centered`, or `stretched`. Default is `stretched`. * `backdrop` - When the background style is `centered`, this specifies the colour of the backdrop for parts of the screen not covered by the background image, in RRGGBB format. * `verbose` - If set to `yes`, print additional information during boot. Defaults to not verbose. * `randomise_memory` - If set to `yes`, randomise the contents of RAM at bootup in order to find bugs related to non zeroed memory or for security reasons. This option will slow down boot time significantly. For the BIOS port of Limine, this will only randomise memory below 4GiB. * `randomize_memory` - Alias of `randomise_memory`. * `hash_mismatch_panic` - If set to `no`, do not panic if there is a hash mismatch for a file, but print a warning instead. Limine interface control options: * `interface_resolution` - Specify screen resolution to be used by the Limine interface (menu, editor, console...) in the form `x`. This will *only* affect the Limine interface, not any booted OS. If not specified, Limine will pick a resolution automatically. If the resolution is not available, Limine will pick another one automatically. Ignored if using text mode. * `interface_branding` - A string that will be displayed on top of the Limine interface. * `interface_branding_colour` - A value between 0 and 7 specifying the colour of the branding string. | Code | Color | |------|----------------| | 0 | Black | | 1 | Red | | 2 | Green | | 3 | Yellow | | 4 | Blue | | 5 | Magenta | | 6 | Cyan (Default) | | 7 | White | * `interface_branding_color` - Alias of `interface_branding_colour`. * `interface_help_hidden` - Hides the help text located at the top of the screen showing the key bindings. Limine graphical terminal control options: These are ignored if using text mode. * `term_font` - Path to a font file to be used instead of the default one for the menu and terminal. The font file must be a code page 437 character set comprised of 256 consecutive glyph bitmaps. Each glyph's bitmap must be expressed left to right (1 byte per row), and top to bottom (16 bytes per whole glyph by default; see `term_font_size`). See e.g. the [VGA text mode font](https://github.com/viler-int10h/vga-text-mode-fonts) collection for fonts. * `term_font_size` - The size of the font in dots, which must correspond to the font file or the display will be garbled. Note that glyphs are always one byte wide, and columns over 8 are empty. Many fonts may be used in both 8- and 9-dot wide variants. Defaults to `8x16`. Ignored if `term_font` not set or if the font fails to load. * `term_font_scale` - Scaling for the font in the x and y directions. `2x2` would display the font in double size, which is useful on high-DPI displays at native resolution. `2x1` only makes the font twice as wide, similar to the VGA 40 column mode. `4x2` might be good for a narrow font on a high resolution display. Values over 8 are disallowed. Default is no scaling, i.e. `1x1`. * `term_font_spacing` - Horizontal spacing, in pixels, between glyphs on screen. It is equivalent to setting a font width of `+`, except this value is preserved even in case font loading fails, and it also applies to the built-in Limine font. Defaults to 1. 0 is allowed. * `term_palette` - Specifies the colour palette used by the terminal (RRGGBB). It is a `;` separated array of 8 colours: black, red, green, brown, blue, magenta, cyan, and gray. Ignored if not using a graphical terminal. * `term_palette_bright` - Specifies the bright colour palette used by the terminal (RRGGBB). It is a `;` separated array of 8 bright colours: dark gray, bright red, bright green, yellow, bright blue, bright magenta, bright cyan, and white. Ignored if not using a graphical terminal. * `term_background` - Terminal text background colour (TTRRGGBB). TT stands for transparency. * `term_foreground` - Terminal text foreground colour (RRGGBB). * `term_background_bright` - Terminal text background bright colour (RRGGBB). * `term_foreground_bright` - Terminal text foreground bright colour (RRGGBB). * `term_margin` - Set the amount of margin around the terminal. * `term_margin_gradient` - Set the thickness in pixel for the gradient around the terminal. Editor control options: * `editor_enabled` - If set to `no`, the editor will not be accessible. Defaults to `yes` unless a config hash is enrolled. * `editor_highlighting` - If set to `no`, syntax highlighting in the editor will be disabled. Defaults to `yes`. * `editor_validation` - If set to `no`, the editor will not alert you about invalid options or syntax errors. Defaults to `yes`. *Locally assignable (non protocol specific) options* are: * `comment` - An optional comment string that will be displayed by the bootloader on the menu when an entry is selected. * `protocol` - The boot protocol that will be used to boot the kernel/executable. Valid protocols are: `linux`, `limine`, `multiboot` (or `multiboot1`), `multiboot2`, `efi`, and `bios`. * `cmdline` - The command line string to be passed to the kernel/executable. Can be omitted. * `kernel_cmdline` - Alias of `cmdline`. > **NOTE:** `uefi` and `efi_chainload` are aliases of the `efi` protocol > option. `bios_chainload` is an alias of the `bios` protocol option. > **NOTE:** BIOS chainloading entries will be hidden when booting using UEFI > and vice-versa. *Locally assignable (protocol specific) options* are: * Linux protocol: * `path` - The path of the kernel. * `kernel_path` - Alias of `path`. * `module_path` - The path to a module (such as initramfs). This option can be specified multiple times to specify multiple modules. * `resolution` - The resolution to be used. This setting takes the form of `xx`. If the resolution is not available, Limine will pick another one automatically. Omitting `` will default to 32. * `textmode` - If set to `yes`, prefer text mode. (BIOS only) * `dtb_path` - A device tree blob to pass instead of the one provided by the firmware. * Limine protocol: * `path` - The path of the executable. * `kernel_path` - Alias of `path`. * `module_path` - The path to a module. This option can be specified multiple times to specify multiple modules. * `module_string` - A string to be associated with a module. This option can also be specified multiple times. It applies to the module described by the last module option specified. * `module_cmdline` - Alias of `module_string`. * `resolution` - The resolution to be used. This setting takes the form of `xx`. If the resolution is not available, Limine will pick another one automatically. Omitting `` will default to 32. * `kaslr` - For relocatable executables, if set to `yes`, enable kernel address space layout randomisation. KASLR is disabled by default. * `randomise_hhdm_base` - If set to `yes`, randomise the base address of the higher half direct map. If set to `no`, do not. By default it is `yes` if KASLR is supported and enabled, else it is `no`. * `randomize_hhdm_base` - Alias of `randomise_hhdm_base`. * `max_paging_mode`, `min_paging_mode` - Limit the maximum and minimum paging modes to one of the following: - x86-64 and aarch64: `4level`, `5level`. - riscv64: `sv39`, `sv48`, `sv57`. - loongarch64: `4level`. * `paging_mode` - Equivalent to setting both `max_paging_mode` and `min_paging_mode` to the same value. * `dtb_path` - A device tree blob to pass instead of the one provided by the firmware. * multiboot1 and multiboot2 protocols: * `path` - The path of the executable. * `kernel_path` - Alias of `path`. * `module_path` - The path to a module. This option can be specified multiple times to specify multiple modules. * `module_string` - A string to be passed to a module. This option can also be specified multiple times. It applies to the module described by the last module option specified. * `resolution` - The resolution to be used should the executable request a graphical framebuffer. This setting takes the form of `xx` and *overrides* any resolution requested by the executable. If the resolution is not available, Limine will pick another one automatically. Omitting `` will default to 32. * `textmode` - If set to `yes`, prefer text mode. (BIOS only) * EFI Chainload protocol: * `path` - Path of the EFI application to chainload. * `image_path` - Alias of `path`. * `resolution` - The resolution to be used. This setting takes the form of `xx`. If the resolution is not available, Limine will pick another one automatically. Omitting `` will default to 32. * BIOS Chainload protocol: * `drive` - The 1-based drive to chainload, if omitted, assume boot drive. * `partition` - The 1-based partition to chainload, if omitted, or set to 0, chainload drive (MBR). * `mbr_id` - Optional. If passed, use an MBR ID (32-bit hex value) to identify the drive containing the volume to chainload. Overrides `drive`, if present, but does *not* override `partition`. * `gpt_uuid` or `gpt_guid` - Optional. If passed, use the GPT GUID to identify the drive containing the volume to chainload. Overrides `drive` and `mbr_id`, if present, but does *not* override `partition`. ## Paths A Limine path is used to locate files in the whole system. It is comprised of a *resource*, a *resource argument*, and a *path*. It takes the form of: ``` resource(argument):/path ``` The format for `argument` changes depending on the resource used. A resource can be one of the following: * `boot` - If booted off PXE this is an alias of `tftp`. Else the `argument` is the 1-based decimal value representing the partition on the boot drive (values of 5+ for MBR logical partitions). If omitted, the partition containing the configuration file on the boot drive is used. For example: `boot(2):/...` will use partition 2 of the boot drive and `boot():/...` will use the partition containing the config file on the boot drive. * `hdd` - Hard disk drives. The `argument` takes the form of `drive:partition`; for example: `hdd(3:1):/...` would use hard drive 3, partition 1. Partitions and drives are both 1-based (partition values of 5+ for MBR logical partitions). Omitting the partition is possible; for example: `hdd(2:):/...`. Omitting the partition will access the entire volume instead of a specific partition (useful for unpartitioned media). * `odd` - Optical disk drives (CDs/DVDs/...). The `argument` takes the form of `drive:partition`; for example: `odd(3:1):/...` would use optical drive 3, partition 1. Partitions and drives are both 1-based (partition values of 5+ for MBR logical partitions). Omitting the partition is possible; for example: `odd(2:):/...`. Omitting the partition will access the entire volume instead of a specific partition (useful for unpartitioned media, which is often the case for optical media). * `guid` - The `argument` takes the form of a GUID/UUID, such as `guid(736b5698-5ae1-4dff-be2c-ef8f44a61c52):/...`. The GUID is that of either a filesystem, when available, or a GPT partition GUID, when using GPT, in a unified namespace. * `uuid` - Alias of `guid`. * `fslabel` - The `argument` is the name of the filesystem label of a partition. * `tftp` - The `argument` is the IP address of the tftp server to load the file from. If the argument is left empty (`tftp():/...`) the file will be loaded from the server Limine booted from. This resource is only available when booting off PXE. A path can optionally be suffixed with a blake2b hash for the referenced file, by appending a pound character (`#`) followed by the blake2b hash. E.g.: `boot():/somemodule.tar#ca6914d2...446b470a`. ## Macros Macros are strings that can be arbitrarily assigned to represent other strings. For example: ``` ${MY_MACRO}=Some text ``` Now, whenever `${MY_MACRO}` is used in the config file (except for an assignment as above), it will be replaced by the text `Some text`. For example: ``` CMDLINE=something before ${MY_MACRO} something after ``` Macros must always be placed inside `${...}` where `...` is the arbitrary macro name. ### Built-in macros Limine automatically defines these macros: * `ARCH` - This built-in macro expands to the architecture of the machine. Possible values are: `x86-64`, `ia-32`, `aarch64`, `riscv64`, `loongarch64`. In the case of IA-32, BIOS or UEFI, the macro will always expand to `x86-64` if the 64-bit extensions are available, else `ia-32`. * `FW_TYPE` - This built-in macro expands to `UEFI` if booted using UEFI firmware, or `BIOS` if booted using legacy x86 BIOS. limine-10.3.0/3RDPARTY.md0000644000000000000000000000575115103344043013305 0ustar rootroot# 3rd Party Software Acknowledgments The Limine project depends on several other projects.
