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

Extra repo LLVM has been updated to 10.0.0. PKGBUILD needs to be updated, I beleive

Thanks for checking. I was using ccm and didn't realise it wouldn't fail if git pull failed for Mesa. As a result, I missed the error in the terminal output. After deleting the Mesa folder it build normally now

Lone_Wolf commented on 2020-04-14 22:01 (UTC)

just did a fresh build of llvm-minimal-git 11.0.0_r351289.994543abc9b-1 and mesa-git 20.1.0_devel.122256.68b40cfe272-1 without problems.

Also checked src/gallium/auxiliary/gallivm/lp_bld_format_srgb.c and it does have the change.

Try again, if that doesn't help you may have a local issue.

Had to add this patch https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4473 to get it to build against llvm-minimal-git. Not sure why it hasn't been merged yet

Lone_Wolf commented on 2020-04-08 11:27 (UTC)

If you apply the patch manually, add --noextract to makepkg.

It's ok to put those lines in prepare() though. If the patch is confirmed to work but takes some time to get merged just let me know and i'll add it.

Many archlinux package maintainers (both aur & repos) do the same when needed.

evernow commented on 2020-04-07 23:09 (UTC)

Ah ok, so I removed my changes in the pkgbuild and placed the patch in the folder and did this:

[daniel@daniel-pc mesa]$ patch --forward --strip=1 --input="$srcdir"./ksp.patch patching file src/amd/llvm/ac_nir_to_llvm.c patching file src/amd/llvm/ac_shader_abi.h patching file src/gallium/drivers/radeonsi/si_pipe.c patching file src/gallium/drivers/radeonsi/si_pipe.h patching file src/gallium/drivers/radeonsi/si_shader_llvm.c Hunk #1 succeeded at 441 with fuzz 1.

I assume I can now do makepkg -si like normal?

Lone_Wolf commented on 2020-04-07 22:02 (UTC) (edited on 2020-04-07 22:06 (UTC) by Lone_Wolf)

prepare() starts in $srcdir, but the patch expects to be run from the folder where src is found. cd into mesa first, then apply the patch. example

  # test patch for kerbal space program
  # see https://gitlab.freedesktop.org/pepp/mesa/-/commit/1b219f2a6106c0045ac2c391b3fc2ba10991e2fc
  cd mesa
  patch --forward --strip=1 --input="$srcdir"/ksp.patch

MESA_WHICH_LLVM is best set in ~/.bashrc or equivalent file for other shells.

evernow commented on 2020-04-07 16:09 (UTC)

How exactly does one apply a patch to this? Need to add this: https://gitlab.freedesktop.org/pepp/mesa/-/commit/1b219f2a6106c0045ac2c391b3fc2ba10991e2fc

To help identify an issue, but I can't figure out how to build it.

I changed prepare() to this:

prepare() { # although removing _build folder in build() function feels more natural, # that interferes with the spirit of makepkg --noextract patch -Np1 < ../ksp.patch if [ -d _build ]; then rm -rf _build fi

Changed top section to this:

source=('mesa::git+https://gitlab.freedesktop.org/mesa/mesa.git' 'ksp.patch' 'LICENSE') md5sums=('SKIP' 'ddf72fc9148f2e5e7c6b0c2be0d73ed2' '5c65a0fe315dd347e09b1f2826a1df5a') sha512sums=('SKIP' '6475a0b381b34a84f54eac0ce55afb6240059561101d3d5467b45ce88da95d308734d24e1fde902b9826f31a1f88f0b1899ba68505f586726447aa68264a034a' '25da77914dded10c1f432ebcbf29941124138824ceecaf1367b3deedafaecabc082d463abcfa3d15abff59f177491472b505bcb5ba0c4a51bb6b93b4721a23c2')

And I edited this section due to me using LLVM from Carlier's repo:

if [[ ! $MESA_WHICH_LLVM ]] ; then MESA_WHICH_LLVM=3 fi

case $MESA_WHICH_LLVM in 1) # aur llvm-minimal-git makedepends+=('llvm-minimal-git') depends+=('llvm-libs-minimal-git') ;; 2) # aur llvm-git # depending on aur-llvm- to avoid mixup with LH llvm-git makedepends+=('aur-llvm-git') depends+=('aur-llvm-libs-git') ;; 3) # mesa-git/llvm-git (lordheavy unofficial repo) makedepends+=('llvm-git' 'clang-git') depends+=('llvm-libs-git') ;; ) esac

But it fails to build, I keep getting this:

ksp.patch ... Passed
LICENSE ... Passed

==> Extracting sources... -> Creating working copy of mesa git repo... Reset branch 'makepkg' ==> Starting prepare()... can't find file to patch at input line 5 Perhaps you used the wrong -p or --strip option? The text leading up to this was:

Any Help is greatly appreciated

Lone_Wolf commented on 2020-03-06 20:43 (UTC)

Confirmed, error appears to be between llvm/clang/polly as mesa doesn't use polly at all.

No idea how to solve that or even where to report it.

Fortunately mesa-git has 3 other choices for llvm.
