Yet Another AtomBIOS Editor
YAABE is an AMD/ATI GPU VBIOS editor with a major focus on exposing the full data structures of the VBIOS, rather than just the notable tidbits an overclocker may want.
This VBIOS editor does not hold your hand; it exposes a lot and you should have
an idea what you're looking for and what it does. It is recommended to view the
header files under atom/ in tandem.
TODO
This BIOS editor is still in its early stages. The most important thing is
simply populating the tables; making ATUI representations for the tables within
atomfirmware.h et al. and hooking it up into the atomtree. There is also a
bunch of smaller things to figure out, which can be be found through
grep -RHine TODO.
Compiling
YAABE is compiled with the Meson build system, and uses the (upcoming) C standard ISO/IEC 9899:2024 (c2x) with GNU extensions (gnu2x), GTK 4.12 UI toolkit, and json5 for python.
Linux
Make sure you have the GTK 4 suite and meson installed. For Debian and kin,
apt-get install libgtk-4-dev python3-json5 mesonthen,
meson setup build
cd build && meson compileHowever, meson is configured by default to make development easier, so if you wish for a release build,
meson setup build --buildtype=release -Db_lto=true
cd build && meson compileWindows
Install MSYS2 (MSYS2 must be installed on an NTFS partition as FAT and ReFS filesystems are incompatible).
Launch MSYS2's MINGW64 environment by running mingw64.exe (you should see a
purple "MINGW64" in your command prompt).
Install mingw toolchain and the gtk4 libraries,
pacman -Syuu # update if it's an old install
pacman -S mingw-w64-x86_64-toolchain base-devel mingw-w64-x86_64-meson mingw-w64-x86_64-gtk4 mingw-w64-x86_64-python-json5 mingw-w64-x86_64-nsisThe msys2 shell root / is the msys2 install location. Your current working
directory when you open the msys2 shell is your username under home/. Plop
the YAABE source in a place you can reach it within msys2, cd to it, and then,
meson setup build
cd build && meson compileOptionally, it is possible to create an installer wizard through NSIS.
To package a theme, place the theme in gtk-assets/share/themes/ and edit
gtk-assets/etc/gtk-4.0/settings.ini accordingly. That said I do reccomend a
theme, which is linked as a submodule and can be pulled in via
git submodule init; git submodule update. Finally,
meson setup build --buildtype=release -Db_lto=true -Dnsis_installer=true
cd build && meson compile nsis_installerUseful Resources
