The [[SimNow]] simulator is a fast and configurable x86 and AMD64 dynamically-translating instruction-level platform simulator. With SimNow users can connect complex software models to form a PC platform emulation environment. [[SimNow]] emulates AMD Athlon 64 and AMD Opteron uniprocessor and multiprocessor based systems that run several commercial operating systems and applications. Specifically, AMD and its partners use SimNow for:

* BIOS and device driver development.
* Prototyping software visible architectural changes.
* Non-intrusive and deterministic measurement and testing of software at the instruction-level.
* Modeling of future platform tradeoffs for correctness and performance analysis.

The simulator contains all the classic pieces of a PC system (CPU, memory, Northbridge, Southbridge, display, IDE drives, floppy, keyboard, and mouse support). Images (hard disk, DVD/CD-ROM, and floppy) can be created in custom sizes with the DiskTool program that is provided with the simulator. A simulation can be saved at any point in the simulation to a media file, from which the simulation can be re-run at a later time.

The configuration of the simulated system (how models are connected together and their settings) and the logical state of all the devices in the simulator are saved in a ‘BSD’ file format.

'''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 ==

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.

== 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'.

'''Tested GCC Versions'''
* GCC12 Works
* GCC14 Fails, run-time errors.
* GCC15 Fails, compile-time errors.

'''Debian 12 Dependencies'''

apt install git build-essential m4 bison flex zlib1g-dev libncurses-dev imagemagick python-is-python3 gnat libssl-dev pkg-config curl

'''FreeBSD 14.2 Dependencies'''

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

'''Configuring and Compiling'''

<nowiki>
### 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
</nowiki>

'''Listing Source Files'''

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

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

'''Fetching Updates'''

<nowiki>
git pull</nowiki>

'''Switching Motherboards'''

If you want to switch motherboards, you must first clean the build environment. Afterwards, continue from the config selection step.
<nowiki>
make distclean</nowiki>

=== Why 15h? ===
Released between 2011 and 2014, AMD's [[fam15h]] (and its approximately-contemporaneous relatives, [[fam10h]], [[fam14h]] and [[fam16h]]) are the final high-performance x86_64 microprocessors lacking most of the limitations newer x86 platforms are encumbered by. In many cases, fam15h hardware can provide a performant, full-featured system, using entirely free and open source software. It enforces no firmware signing (allowing things such as [[coreboot]]), can be booted entirely with free firmware (including memory initialization), and it requires no privileged management coprocessor (such as the Platform Security Processor or Management Engine, found on newer AMD and Intel platforms respectively). Where a [[Board Management Controller]] is present, it can usually reliably disabled, or better yet, flashed with [[OpenBMC]]. On fam10h, even microcode is unencrypted and unsigned, and can be modified by the user.

Beyond their currently-unparalleled degree of firmware freedom for a modern x86_64 platform, AMD hardware of this era (in particular, 6200 and 6300-series [[Opteron]] platforms) remains a powerful and cost-effective option for many systems, especially under parallel workloads. Despite this, the comparative popularity of competing Intel processors during this era has limited the familiarity and uptake of these pre-Zen AMD platforms among many enthusiasts.

If you are looking for an x86_64 platform under your complete control, this website serves to demystify fam15h and its relatives, so that these systems can remain in operation well into the future.

=== What hardware was that again? ===
Robust support for coreboot on select fam15h motherboards has been developed and thoroughly tested at 15h.org. The current, production ready motherboards are [[KGPE-D16]], [[KCMA-D8]], [[H8QG6]], [[H8SGL]], and [[H8SCM]]. A handful of other fam15h motherboards have [[Motherboards|preliminary support]]. For these motherboards, the [[Bulldozer]] and [[Piledriver]] microarchitectures are supported by [[coreboot-15h]].
