Mesa git frequently built with llvm svn snapshots and LTO enabled. In addition to that libdrm updates are provided aswell.
For x86_64 you have to enable both the 64bit and 32bit repositories for llvm and mesa:
For llvm manually create a che-llvm.repo file in /etc/yum.repos.d/ with the following content:
[che-llvm] name=Copr repo for llvm owned by che baseurl=https://copr-be.cloud.fedoraproject.org/results/che/llvm/fedora-$releasever-$basearch/ skip_if_unavailable=True gpgcheck=1 gpgkey=https://copr-be.cloud.fedoraproject.org/results/che/llvm/pubkey.gpg enabled=1 enabled_metadata=1 [che-llvm-x86] name=Copr repo for llvm i386 owned by che baseurl=https://copr-be.cloud.fedoraproject.org/results/che/llvm/fedora-$releasever-i386/ skip_if_unavailable=True gpgcheck=1 gpgkey=https://copr-be.cloud.fedoraproject.org/results/che/llvm/pubkey.gpg enabled=1 enabled_metadata=1
For mesa and libdrm create a che-mesa.repo file in /etc/yum.repos.d/ with the following content:
[che-mesa] name=Copr repo for mesa owned by che baseurl=https://copr-be.cloud.fedoraproject.org/results/che/mesa/fedora-$releasever-$basearch/ skip_if_unavailable=True gpgcheck=1 gpgkey=https://copr-be.cloud.fedoraproject.org/results/che/mesa/pubkey.gpg enabled=1 enabled_metadata=1 [che-mesa-x86] name=Copr repo for mesa i386 owned by che baseurl=https://copr-be.cloud.fedoraproject.org/results/che/mesa/fedora-$releasever-i386/ skip_if_unavailable=True gpgcheck=1 gpgkey=https://copr-be.cloud.fedoraproject.org/results/che/mesa/pubkey.gpg enabled=1 enabled_metadata=1
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!
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:
