removed obsolete options, build now works again.

building opencl clover is disabled for now, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/11863

Those that need opencl should use rusticl instead. Note that rusticl at runtime is disabled by default, see https://docs.mesa3d.org/envvars.html#rusticl-environment-variables for info about enabling it.

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

@Nefsen402,

Thanks for the report. Mesa classic drivers removed. Removed drivers are Radeon R100 and R200, old (non-gallium) Nouveau, and Intel i915 and i965.

Nefsen402 commented on 2021-12-05 10:28 (UTC)

Please remove the flag for dri drivers from the pkgbuild. As of https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10153 the classic drivers have been deleted and mesa-git will no longer build as it tries to build mesa with the old legacy drivers still.

@enen92, thanks for the report. PKGBUILD updated to use llvm 13.0.0

enen92, please check the first pinned commit.

The installed llvm version needs to be the same as the version mesa-git was build against. Incase the installed version changes, mesa-git MUST be rebuilt or there will be all kinds of graphical failures including black screens.

The strict version depend for repo llvm is to protect users from such issues.

Those that know enough about their own system/pacman/makepkg to not need such protection should also be able to adjust 3 values on 2 lines in the PKGBUILD themselves.

Edit: thanks for reporting this.

enen92 commented on 2021-11-13 12:11 (UTC)

Hey, getting the following dependency failures after my last pacman sync:

==> Missing dependencies: -> llvm=12.0.1 -> clang=12.0.1

Installed packages from arch repos:

➜ ~ pacman -Q | grep clang clang 13.0.0-2 ➜ ~ pacman -Q | grep llvm-libs lib32-llvm-libs 13.0.0-1 llvm-libs 13.0.0-3

Mesa-git compiles, installs and runs fine with the above dependencies installed (--nodeps). Maybe the above required dependencies versions can be relaxed?

Cheers

@hkto
You can look at https://mesamatrix.net/#OpenCL which tracks the Mesa Git features.txt in a nice, HTML'ed interface.

In short, yes. Currently, mesa only provides OpenCL 1.2 but with limited OpenCL image support plus some OpenCL 3.0 support.

For AMD cards, if you want to have a conformant OpenCL alongside this package, you can use https://aur.archlinux.org/packages/opencl-amd/
It provides OpenCL userspace driver as provided in the amdgpu-pro driver stack.

hkto commented on 2021-11-09 11:37 (UTC)

Sorry if this is an obvious question, but could somebody tell me what version of OpenCL this provides? I'm trying to get 1.2 or above.

Lone_Wolf commented on 2021-10-26 11:07 (UTC)

The time has come for me to transfer ownership of this package to Reza and step down as maintainer.

Since xorg-server has mesa-libgl in its makedepends list, it makes sense for xorg-server user packages to also have the same requirement. So they need mesa-git to provide it in order to be able to be built against. As @Lone_Wolf mentioned previously, mesa-libgl is no longer a real package so it seems all xorg-server packages could remove it from their makedepends list but this change is sort of unrealistic to expect. Since there's no harm in adding mesa-libgl to the mesa-git, I'm going to go ahead and add it. It also makes mesa-git more conformant with the official mesa package. Let me know if you have any objections to this.
