ACO was merged in mesa mainline!
This repo will continue building from Daniel Schuermann's github - master branch..
You should also consider using mesa-and-llvm-git or mesa-git for the future, to benefit from latest improvements!
This repo is a modified version of che-mesa.
- Triggered to be rebuilt every few hours if code update is detected.
- Is set to follow Valve's Radeon ACO compiler patches from Daniel Schuermann's github - master branch.
- More details in Valve's official announcement.
- Testing instructions
- Backend capabilities. (Check here supported hardware)
- Built with LLVM 9 and LTO enabled. At least because of this, it should provide a smoother transition for Navi. In addition to that libdrm updates are provided as well.
For the ones feeling adventurous, highly experimental, it might break from time to time: mesa-git built against llvm-git at regular intervals, can be found here
For x86_64 you have to enable both the 64bit and 32bit repositories, because most of the games are still 32 bit applications.
For mesa and libdrm create a mesa-aco.repo file in /etc/yum.repos.d/ with the following content:
[mesa-aco] name=Copr repo for mesa with ACO patches - x86_64 baseurl=https://copr-be.cloud.fedoraproject.org/results/xxmitsu/mesa-aco/fedora-$releasever-$basearch/ skip_if_unavailable=True gpgcheck=1 gpgkey=https://copr-be.cloud.fedoraproject.org/results/xxmitsu/mesa-aco/pubkey.gpg enabled=1 enabled_metadata=1 [mesa-aco-x86] name=Copr repo for mesa with ACO patches - i386 baseurl=https://copr-be.cloud.fedoraproject.org/results/xxmitsu/mesa-aco/fedora-$releasever-i386/ skip_if_unavailable=True gpgcheck=1 gpgkey=https://copr-be.cloud.fedoraproject.org/results/xxmitsu/mesa-aco/pubkey.gpg enabled=1 enabled_metadata=1
Due to the following issue, rawhide users, might need to manually modify their $releasever to rawhide.
Important for distribution upgrades or first time installs:
The packages beignet and pocl are not supplied by the repository but installed by default with new installs and distro upgrades, since they both rarely build against llvm svn and mesa git. Please remove the packages manually to avoid any errors when installing the mesa and llvm updates the first time or after a distribution upgrade. For various reasons i do not want to obsolete both packages to get them removed automatically:
dnf remove beignet pocl
GDM Startup hangs, I can see a black screen and a mouse cursor that can not be moved
This is a known issue, see: https://gitlab.gnome.org/GNOME/mutter/merge_requests/619 The only way of fixing this is to either manually patch mutter or wait until a new mutter package is provided.
NOTE: updated mutter packages are now available in updates for f29 and f30! Thanks to the official Fedora maintainer Florian Muellner!
Possible workaround: If you do not care about wayland sessions you can edit /etc/gdm/custom.conf and uncomment: WaylandEnable=false This will make gdm start but you will have no more wayland options until you comment it out again.
Mouse clicks not working in GDM/Gnome-Shell/Mutter:
Additionally the latest mesa exposes RGB10 with radeonsi by default. This leads to the problem with gdm and gnome-shell that mouse clicks are not recieved by the applications when using wayland. If you are affected by the problem the workaround is to turn off RGB10 exposure to gdm/gnome-shell:
echo "allow_rgb10_configs=false" >> /etc/environment
The problem has been reported by Mikhail Gavrilov and he was also kind enough to notify me of the workaround that was provided on the amd-gfx mailinglist. He also reported the problem upstream: Bug Report. Thank you Mikhail!
How do i use amdgpu for my si/cik card to get vulkan support?
Important: If you make your system unbootable by screwing up your grub.cfg, do not blame me! I am not recommending you to do this change!
BUG: With kernel-4.18.18 it still works, but all kernel-4.19 versions seem to have a bug that prevents this from working (I will follow up on this here), resulting in a black screen when the login manager is supposed to appear. This is not a bug in mesa!
ACO backend won't work for those users because as of now, it only supports VI+ cards (Tonga and newer). However, the official llvm backend still works and can be toggled using:
For SI cards the following kernel boot parameters will enable the amdgpu kernel driver and turn off radeon support:
For CIK cards the following kernel boot parameters will enable the amdgpu kernel driver and turn off radeon support:
If you want to run Xorg based sessions with your SI or CIK card and the amdgpu kernel driver you will also need to install the amdgpu xorg driver:
dnf install xorg-x11-drv-amdgpu
How do i get back to stock versions of mesa and llvm?
For that you simply disable the repositories and run:
