'''Coreboot-15h''', also known as '''Mike's Coreboot''', is a distribution of [[Coreboot]] for the ASUS [[KGPE-D16]], developed by [[User:Mrothfuss|mrothfuss]], focused on improving reliability and hardware compatibility over upstream Coreboot 4.11 and [[Dasharo]] 0.4.0. coreboot-15h includes changes for dramatically more stable memory initialization, significantly improved HyperTransport configuration, support for hardware monitoring and fan control, and patches to the build system to allow building on current Linux distributions. It is, at the time of writing, believed to be the most stable and complete Coreboot variant available for the hardware it targets.

'''coreboot-15h''', also known as '''Mike's coreboot''', is a distribution of [[coreboot]] for various [[Family 15h]] motherboards, developed by [[User:Mrothfuss|mrothfuss]], using AMD's open-source fam15h AGESA and CIMX for initialization. This has allowed for the reintroduction of several boards long-deprecated upstream (such as the [[H8QGi+-F]]), and has allowed several previously-unsupported Family 15h boards (particularly others from [[Supermicro]]) to be ported. On [[ASUS]] boards that were once supported by [[Raptor Engineering]]'s native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and [[Dasharo]] 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.


== History ==
== History ==
As '''coreboot-D16''', coreboot-15h was previously provided in two versions - <code>coreboot-4.11</code> and <code>coreboot-4.15</code>. The former was based on upstream Coreboot 4.11, while the latter is based on Dasharo's KGPE-D16 port (an earlier out-of-tree effort to reintroduce KGPE-D16 support in Coreboot, ultimately not upstreamed), which is itself effectively a fork of Coreboot around the 4.15 release. Despite being based on an older version of Coreboot, the coreboot-4.11 version was more actively developed, was in much more widespread use, has seen significantly more testing, and was generally considered more stable and performant. The older <code>coreboot-4.15</code> version can be found in [https://github.com/mrothfuss/coreboot-D16/ the old GitHub repo].


coreboot-D16 also includes a modified version of <code>fand.cpp</code>, for use with OpenBMC, providing improved BMC-based fan control for KGPE-D16 users running [[OpenBMC]]. At present, you will need to manually replace this file in your OpenBMC source with the coreboot-D16 version before building OpenBMC in order to use it.
Attempts were made in 2022 to complete the [[Raptor Engineering]] port of coreboot for the [[KGPE-D16|ASUS KGPE-D16]] motherboard. This involved an effort by [[User:Mrothfuss|mrothfuss]] to fix bugs in the previous 4.11 codebase<ref>https://github.com/mrothfuss/coreboot-D16 coreboot-D16</ref> and development by [[Dasharo]] to migrate the platform to coreboot 4.15<ref>https://docs.dasharo.com/variants/asus_kgpe_d16/overview/</ref>. Improvements made by [[User:Mrothfuss|mrothfuss]] were upstreamed to [[Dasharo]]'s fork<ref>https://github.com/Dasharo/coreboot/pull/116</ref>. Both efforts ultimately failed to produce reliable firmware for the [[KGPE-D16|ASUS KGPE-D16]] motherboard.
 
Initial testing and development of AMD's open source AGESA/CIMx codebases by [[User:Mrothfuss|mrothfuss]] began in 2023 as a fork of coreboot 4.0 called [https://github.com/mrothfuss/coreboot-agesa coreboot-agesa]. Support for AMD Fam15 on the existing [[Supermicro]] [[H8SCM]] and [[H8QGi%2B-F]] motherboards was confirmed and improved. A new port for the [[H8DGi]] was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the [[KGPE-D16|ASUS KGPE-D16]]. Compilation of this old source code, however, required an inconvenient Debian 6 environment.
 
In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the [[coreboot-15h]] project. Initially the previous [[Supermicro]] motherboards ([[H8QGi%2B-F]], [[H8DGi]], [[H8SCM]]) were supported. New AGESA/CIMx ports for the [[ASUS]] motherboards, [[KGPE-D16]] and [[KCMA-D8]], were developed and tested by [[User:Mrothfuss|mrothfuss]] and [[User:Rane|rane]]. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, [[coreboot-15h]] surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.

Latest revision as of 18:17, 19 November 2025

coreboot-15h, also known as Mike's coreboot, is a distribution of coreboot for various Family 15h motherboards, developed by mrothfuss, using AMD's open-source fam15h AGESA and CIMX for initialization. This has allowed for the reintroduction of several boards long-deprecated upstream (such as the H8QGi+-F), and has allowed several previously-unsupported Family 15h boards (particularly others from Supermicro) to be ported. On ASUS boards that were once supported by Raptor Engineering's native initialization implementation (removed upstream in coreboot 4.12), coreboot-15h offers improved reliability and hardware compatibility over upstream coreboot 4.11 and Dasharo 0.4.0. Improvements include dramatically more reliable memory initialization (including support for more memory and denser modules), improved stability once booted, significantly improved HyperTransport configuration, native support for hardware monitoring and fan control, and patches to the build system to allow building on modern platforms. It is, at the time of writing, believed to be the most stable and complete coreboot variant available for the hardware it targets, and it currently appears to be the only actively-developed coreboot variant supporting family 15h.

History

Attempts were made in 2022 to complete the Raptor Engineering port of coreboot for the ASUS KGPE-D16 motherboard. This involved an effort by mrothfuss to fix bugs in the previous 4.11 codebase[1] and development by Dasharo to migrate the platform to coreboot 4.15[2]. Improvements made by mrothfuss were upstreamed to Dasharo's fork[3]. Both efforts ultimately failed to produce reliable firmware for the ASUS KGPE-D16 motherboard.

Initial testing and development of AMD's open source AGESA/CIMx codebases by mrothfuss began in 2023 as a fork of coreboot 4.0 called coreboot-agesa. Support for AMD Fam15 on the existing Supermicro H8SCM and H8QGi+-F motherboards was confirmed and improved. A new port for the H8DGi was successfully made using this codebase, providing a reliable and performant dual socket G34 motherboard similar to the ASUS KGPE-D16. Compilation of this old source code, however, required an inconvenient Debian 6 environment.

In early 2025, the AGESA/CIMx codebases were successfully reintegrated into coreboot 4.11 under the coreboot-15h project. Initially the previous Supermicro motherboards (H8QGi+-F, H8DGi, H8SCM) were supported. New AGESA/CIMx ports for the ASUS motherboards, KGPE-D16 and KCMA-D8, were developed and tested by mrothfuss and rane. Integration of the AGESA/CIMx codebase into coreboot was subsequently improved, namely adding IOMMU support for AMD Fam15 motherboards. At this point, coreboot-15h surpassed all other firmware options for the supported motherboards; providing more features, better multicore performance, better power efficiency, and speculative-execution mitigation support.

Compiling coreboot from source

Compilation has been tested on Debian 12 and FreeBSD 14.2. Building on FreeBSD is the same as building on Linux, but 'make' is replaced with 'gmake'.

Debian 12 Dependencies 

apt install git build-essential m4 bison flex zlib1g-dev libncurses-dev imagemagick python-is-python3

FreeBSD 14.2 Dependencies 

### This list may be incomplete
pkg install git bash gmake gcc12 m4 bison ImageMagick7  python autoconf automake gettext-tools gnu-unifont

Configuring and Compiling 

### Fetch coreboot-15h source
# Tip: Add the '--depth=1' argument to save bandwidth. You
#      will not be able to checkout previous commits if you
#      use this shallow clone option.
git clone https://git.15h.org/mrothfuss/coreboot-15h.git
cd coreboot-15h

### Optional: Checkout a specific commit to reproduce a release
# git commit-id's are included at the end of a release name
# Example: 2025.11.09-v4.11-6f1fd5cf220
git checkout 6f1fd5cf220

### Optional: Fetch blobs (required for VGABIOS ROMs)
# Blobs can be explicitly excluded from the build by menuconfig
# Tip: Add the '--depth=1' argument to save bandwidth
git submodule update --init --checkout 3rdparty/blobs

### Optional: Manually fetch the vboot submodule
# This submodule will be fetched automatically, but needs to be
# manually downloaded if you want to use the 'UPDATED_SUBMODULES=1'
# option during the coreboot.rom compilation (see below).
# Tip: Add the '--depth=1' argument to save bandwidth
git submodule update --init --checkout 3rdparty/vboot

### Build the cross compiler (may take a while)
make crossgcc-i386 CPUS=$(nproc)

### Select a config template from ./configs
# These config files are used to compile the releases distributed on 15h.org
# Copy the config you want to start with, you can adjust it in the next step
cp configs/config.asus_kgpe-d16_seabios_ucode_ast2050-oprom_vga-oproms_2mb .config

### Optional: Review or adjust your configuration
make menuconfig

### Build coreboot, your ROM will be at ./build/coreboot.rom
# Tip: Add the 'UPDATED_SUBMODULES=1' argument to skip fetching/updating all submodules
make

Listing Source Files

To review a precise list of files compiled into your ./build/coreboot.rom file, use this command. 

make filelist

This command works after a successful 'make' and changes depending on the motherboard and configuration options selected.

Fetching Updates 

git pull

Switching Motherboards

If you want to switch motherboards, you must first clean the build environment. Afterwards, continue from the config selection step. 

make distclean
