rusticl is now provided by opencl-mesa.

Note that only a few hardware drivers are supported by default, see https://docs.mesa3d.org/envvars.html#rusticl-environment-variables for info about enabling others.

Mesa and llvm are closely tied together. Everytime the llvm mesa is built against changes/updates , mesa needs to be rebuilt.

I expect anyone building mesa-git against one of the llvm trunk variants to be able to do that themselves, but atleast some of the people that built against repo llvm don't understand how to deal with such a rebuild.

The rest of this post is meant for those people.

  • Verify if latest PKGBUILD requirements match llvm repo versions.
  • If they don't , post to alert the maintainer of this.
  • DELAY the update of llvm/clang suite and their lib32- counterparts
  • Once the PKGBUILD does match, download it.

Option A - best one

  • run pacman -Syu to ensure your system is in sync with your mirrror server
  • build mesa-git in a clean chroot

see https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_clean_chroot for the official way or https://aur.archlinux.org/packages/clean-chroot-manager for an alternative method.

  • install the newly built mesa-git
  • run pacman -Syu
  • ready

Option B - 2nd best

  • revert to repo mesa
  • pacman -Syu
  • build mesa-git
  • switch from mesa to mesa-git
  • ready

  • choosing which llvm variant to build against

WARNING : aur helpers don't support this method at all. They check .SRCINFO and that doesn't include this variable so it will use the default which is hardcoded to build against repo llvm.

Why would I want to use llvm development versions ?

For full functionality and latest features mesa trunk master needs to be build against llvm trunk master.
If you build against stable llvm things MAY work, but you're likely to lack some features and face stability issues.

Mesa-git uses a custom environment variable MESA_WHICH_LLVM for flexibility.
It has 4 values.
1 : aur llvm-minimal-git
2 : aur llvm-git
3: llvm-git from LordHeavy' unofficial repo
4: llvm from extra repo

I use value 1 95% of the time and set this in ~/.bash_rc .
If MESA_WHICH_LLVM is unset or empty, the default value of 4 (extra llvm) is used.

  • main difference with stable repo package
[extra]mesa is a split package, but aur mesa-git isn't.
Basically with aur mesa-git you get everything in one package, while [extra]/mesa allows you to leave out some parts if you don't want/need them.
Having a single package reduces maintenance and makes switching from stable to mesa-git rather easy, though reverting back to stable can be tricky.
  • meson settings
Those who compare PKGBUILDs will notice I don't use arch-meson, but meson setup.
I disagree with some of the settings made by arch-meson (especially the buildtype and enabling LTO by default) and feel using meson setup is cleaner.
  • how to update

run pacman Syu update non-repo packages for llvm if you use them

build mesa-git, log out , update mesa-git and restart X .

run glxinfo -B to verify basic OpenGL functionality

build lib32-mesa-git

run glxinfo32 -B to verify basic OpenGL functionality for multilib programs

New package is not suited for use , mesa can currently only use venus-protocol as meson subproject.

venus-protocol support added to PKGBUILD

Lone_Wolf commented on 2026-08-11 15:57 (UTC)

New package https://aur.archlinux.org/packages/venus-protocol-git created & submitted, working on using it.

Lone_Wolf commented on 2026-08-07 20:28 (UTC)

Using --wrap-mode=default is a bad idea as you loose control and allow meson to download anything it detects as 'missing' which has a high chance of pulling in unwanted stuff.

Adding support for the venus-protocol requires a new package. For aur that's blocked and since venus-protocol became a dep in master just 4 days ago and is not included in 26.2 arch devs have no need to add it to extra.

Removing virtio from the vulkan-drivers line is much simpler and has no bad consequences apart from loosing vulkan support in VMs .

quark23 commented on 2026-08-07 06:34 (UTC)

If build fails due to missing venus-protocol dependency for meson just change --wrap-mode=nofallback to --wrap-mode=default

Note that builds in the last day or so include a patch that detects the broken libclc distributed with LLVM 22.x and prevents the compilation of OpenCL kernels that rely on it. If your OpenCL support suddenly stopped working, maybe that's why.

There's an issue here with a patch for libclc that'll fix the issue: https://gitlab.archlinux.org/archlinux/packaging/packages/libclc/-/work_items/13

EDIT: I made an AUR package with the patch: https://aur.archlinux.org/packages/libclc-patch-broken-flush-denormal

Lone_Wolf commented on 2026-06-28 11:39 (UTC)

Note that the gallium virgl and vulkan virtio driver are build so it's not like mesa-git has no support for VMs.

If we add -D amdgpu-virtio=true we should also add -D intel-virtio-experimental=true to ensure both amd and intel are supported.

BadAtNames commented on 2026-06-27 22:26 (UTC)

I think this package should set -Damdgpu-virtio=true, like the main arch package, otherwise it doesn't work in gpu native contexts

@LandonDeam, @JasonKhew96, @linkmauve,

Thanks for your comments. Python is no longer a runtime dependency. crates.io download is now pointing to CDN to avoid the rate-limit problem.

LandonDeam commented on 2026-06-03 01:14 (UTC) (edited on 2026-06-03 01:15 (UTC) by LandonDeam)

This patch should fix the API error by just talking directly to the CDN as mentioned by JasonKhew96

crates.io now returns 403 due to the rate limit and user agent blocking [0]

should change the download url to static.crates.io [1]
