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

Thanks for the input , HurricanePootis . If mesa-git only needed to build against repo llvm/clang your patch would work. Unfortunately that's not the case.

Mesa-git package supports building against 4 llvm variants (three of which are llvm trunk versions). Any options used need to work with all of them. I see four changes in your patch and will discuss them below.

  • adding intel-nullhw: while it seems to be exlusively used for debugging on intel hardware, it is an official vulkan extension and could be added.

  • enabling intel-clc : supports raytracing with vulkan on some intel hardware. I am not aware of it being enabled in any aur mesa trunk package so it will need to be tested. If you (or others) want to help try building mesa-git with that option enabled against llvm-minimal-git or llvm-git (once those are confirmed to work, building against lordheavy's llvm trunk packages would also help).

  • opencl-mesa in repos provides 2 things : clover and rusticl .

  • clover (aka gallium-opencl) build has been broken with llvm trunk (17+) since februari and continues to fail. The bug ticket https://gitlab.freedesktop.org/mesa/mesa/-/issues/8591 hasn't seen recent activity. Until it is solved mesa-git can't re-enable it.

  • rusticl

quoted from https://docs.mesa3d.org/rusticl.html SPIRV-LLVM-Translator for a libLLVMSPIRVLib.so matching your version of LLVM, i.e. if you’re using LLVM 15 (libLLVM.so.15), then you need a libLLVMSPIRVLib.so.15.1

extra/spirv-llvm-translator is build against repo llvm and doesn't work with llvm trunk. All llvm trunk varaints need their own version of spirv-llvm-tranalator AND libclc build against their specific llvm variant.

currently those packages don't exist for llvm-git. Someone needs to create and maintain them. Once that has been done rusticl will work with all 4 llvm variants supported by this package and can be added.

If anyone wants to give it a try, look at my aur spirv-llvm-translator-minimal-git & libclc-minimal-git packages to get started.

HurricanePootis commented on 2023-06-28 03:48 (UTC)

Hello, this is a comment with a patch that will make mesa-git more in-line with mesa. This patch adds Rusticl, intel-clc, renables opencl-mesa, and adds the required makedeps and depends for rusticl and intel-clc. I have also left a comment on lib32-mesa-git that has a singular patch that will make it more in-line with lib32-mesa.

@kanadeaur : that output indicates you're not using this package but Lordheavy's mesa-git repository, see https://wiki.archlinux.org/title/Unofficial_user_repositories#mesa-git .

We can't help with that.

This package builds mesa trunk. mesa 3.1 was branched off from trunk on april 10 . That means trunk is now hundreds of commits ahead of mesa stable.

Do you have proof that your error is also present in (recent) mesa trunk builds ?

apostol commented on 2023-06-12 16:43 (UTC)

Today's update broke WebGL in browser (for example - maps.google.com).

Downgrading mesa to mesa-23.0.3-1 solved the issue for me: pamac install downgrade && downgrade mesa

If you run:

git config — global http.postBuffer 157286400

It should get past that... but yeah a proper fix may be good?
