Use it at your own risk!

This repo is a modified version of che-mesa.

Triggered to be rebuilt every few hours if code update is detected. <br /> Is set to follow the official mesa gitlab repo https://gitlab.freedesktop.org/mesa/mesa<br /> Built with Distro's LLVM. Due to this, it might happen for rawhide builds to fail until upstream adapts mesa with the changes required for new llvm versions. <br />

For x86_64 you have to enable both the 64bit and 32bit repositories, because most of the games are still 32 bit applications.

Usually, the recommended command should work:

dnf copr enable xxmitsu/mesa-git

However, if you encounter issues, create a mesa-git.repo file in /etc/yum.repos.d/ with the following content:

[mesa-git]
name=Copr repo with mesa built from the official mesa git - x86_64
baseurl=https://copr-be.cloud.fedoraproject.org/results/xxmitsu/mesa-git/fedora-$releasever-$basearch/
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://copr-be.cloud.fedoraproject.org/results/xxmitsu/mesa-git/pubkey.gpg
enabled=1
enabled_metadata=1

[mesa-git-x86]
name=Copr repo with mesa built from the official mesa git - i386
baseurl=https://copr-be.cloud.fedoraproject.org/results/xxmitsu/mesa-git/fedora-$releasever-i386/

Rawhide users:

Due to the following issue, rawhide users, might need to manually modify their $releasever to rawhide.

For AMDGPU owners, ACO backend is now default backend for RADV:

• The ACO backend was enabled by default for RADV(Vulkan) as of 2020-06-25.
• RADV_DEBUG=llvm option can be used to enable legacy LLVM backend.
• RustiCL enabled as of October 2023. To test it, see RUSTICL_ENABLE env var.
• NVK Vulkan driver (nouveau experimental) has been included as of February 2024. To test it use: NVK_I_WANT_A_BROKEN_VULKAN_DRIVER=1 and potentially NVK_USE_NAK=all.
• As of August 2024, it was requested not to compile mesa with patented codecs enabled. Unfortunately, this action will disable hardware acceleration for: h264 and h265 codecs.

Vulkan selection layer:

• This is the vulkan equivalent of DRI_PRIME=1. Usage instructions:

• Get your device's vendor id and device id

  # lspci -nn | grep -i vga
  43:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Vega 20 [Radeon VII] [1002:66af] (rev c1)

• Set before game launch command:

  MESA_VK_DEVICE_SELECT=vendor:device

• Example for Steam launch options, using the above determined device id:

  MESA_VK_DEVICE_SELECT=1002:66af %command%

Knowledgebase:

In case you encounter a recent regression introduced in mesa-git, don't forget to report it using mesa official bug tracker.

Here is how you can make your system stable again in this situation:

Temporary revert to official stable packages:

dnf --disablerepo=copr:copr.fedorainfracloud.org:xxmitsu:mesa-git* distro-sync

Re-install the mesa-git packages from this repo after code changes to see if the bug was fixed:

dnf  update --refresh   -y

Copr key expires periodically:

If you encounter a similar error:

error: Verifying a signature using certificate 108E08A840EB2548E6B43856702E7C6094CBA2BC (xxmitsu_mesa-git (None) <xxmitsu#mesa-git@copr.fedorahosted.org>):
    1. Certificiate 702E7C6094CBA2BC invalid: certificate is not alive
        because: The primary key is not live
        because: Expired on 2024-07-07T08:17:02Z
    2. Key 702E7C6094CBA2BC invalid: key is not alive
        because: The primary key is not live
        because: Expired on 2024-07-07T08:17:02Z

• Find out the name of the old expired key:

host$ rpm -q --qf "%{NAME}-%{VERSION}-%{RELEASE}\t%{SUMMARY}\n" gpg-pubkey | grep xxmitsu
gpg-pubkey-94cba2bc-5d244d7e	xxmitsu_mesa-git (None) <xxmitsu#mesa-git@copr.fedorahosted.org> public key

• Erase it:

host$ sudo rpm -e gpg-pubkey-94cba2bc-5d244d7e

• Then, re-accept the new key when running the update command again or manually import it using:

host$ sudo rpm --import https://download.copr.fedorainfracloud.org/results/xxmitsu/mesa-git/pubkey.gpg

Chromium-based browsers display garbled web pages after Mesa is updated:

After a recent update to the Mesa graphics library, many users have reported that Chromium-based browsers or Electron-based apps fail to render webpages/interface correctly and produce garbled results. As a known workaround, please delete the old chromium cache as the following:

rm -rf ~/.config/google-chrome/GrShaderCache
rm -rf ~/.config/google-chrome/ShaderCache
rm -rf ~/.config/google-chrome/Default/GPUCache

• For potential other solutions, see the bug reports from here and here.

Visual Studio Code produces misrendering

It suffers from the same issue described above that affects Electron-based apps.

Current workaround is to delete the GPU cache located at ~/.config/Code/GPUCache.

See official release note.

Game not launching since Fedora 38 update:

Try disabling lavapipe:

VK_LOADER_DRIVERS_DISABLE=*lvp* steam

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!

For SI cards the following kernel boot parameters will enable the amdgpu kernel driver and turn off radeon support:

amdgpu.si_support=1 radeon.si_support=0 

For CIK cards the following kernel boot parameters will enable the amdgpu kernel driver and turn off radeon support:

amdgpu.cik_support=1 radeon.cik_support=0

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:

dnf distro-sync
