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

I am unable to update it I get when updating llvm-libs: 

error: failed to prepare transaction (could not satisfy dependencies)
:: installing lib32-llvm-libs (11.0.1-1) breaks dependency 'lib32-llvm-libs=11.0.0' required by lib32-mesa-git
:: installing llvm-libs (11.0.1-1) breaks dependency 'llvm-libs=11.0.0' required by mesa-git

I get this when updating mesa-git:

==> Missing dependencies:
  -> llvm-libs=11.0.1
==> Checking buildtime dependencies...
==> ERROR: Could not resolve all dependencies.
error making: mesa-git

@le_tucan i just logged in to comment the same thing. Thanks for reporting

le_tucan commented on 2021-01-11 14:18 (UTC)

llvm got an update, so the dependencies are outdated, line 74 and 75 in PKGBUILD need to be ">=11.0.0"

Lone_Wolf commented on 2021-01-03 15:37 (UTC)

That's an adjustment for building with devtools, correcting now.

elovin commented on 2021-01-03 15:28 (UTC)

In the last commit "57e4140fd5bb" you added the line:

MESA_WHICH_LLVM=1

above the if statement:

if [[ ! $MESA_WHICH_LLVM ]] ; then MESA_WHICH_LLVM=4 fi

now the script always uses option 1 for MESA_WHICH_LLVM (minimal llvm)

VK_ICD_FILENAMES as a launch option has always worked for me in Steam. Now you got me wondering, I am going to recompile mesa with the swrast option and see what happen here.

EDIT:

Tested with amdvlk, vulkan-radeon, vulkan-mesa, and vulkan-intel. Without using VK_ICD_FILENAMES, Steam used amdvlk for the five games I tested. Without amdvlk, Steame use vulkan-radeon on every game. I don't see how swrast is causing a problem, unless it a dx12 proton issue. all games I tested were dx11.

Using VK_ICD_FILENAMES worked on every game also.

A script like that will be very compilcated to get right, as there are atleast 7 possible vulkan drivers that theoretically can all be present at same time. vulkan-intel, nvidia-utils , vulkan-radeon, amdvlk, vulkan-amdgpu-pro and lavapipe (vulkan-mesa) .

I did some searching to get clear what the real problem is .

vulkaninfo from my own system

Layers: count = 2
=================
VK_LAYER_MESA_device_select (Linux device selection layer) Vulkan version 1.1.73, layer version 1:
        Layer Extensions: count = 0
        Devices: count = 2
                GPU id = 0 (AMD RADV POLARIS10 (ACO))
                Layer-Device Extensions: count = 0

                GPU id = 1 (llvmpipe (LLVM 12.0.0, 256 bits))
                Layer-Device Extensions: count = 0

So lavapipe does support VK_LAYER_MESA_device_select .

I found several bugreports that appear relevant [1][2].

quoting from [2]

Using a custom per-game driver (like with VK_ICD_FILENAMES or LIBGL_DRIVERS_PATH) doesn't work

This suggests that the problem is not with lavapipe, but in steam / proton having trouble if there's more then one vulkan driver present.

That means disabling lavapipe won't solve the issue since there will still be 2 vulkan drivers present : RADV (vulkan-radeon) & ANV (vulkan-intel) .

Even splitting of the 3 vulkan drivers to their own packages will still allow installing 2 or more unless I have them conflict .

Telling people to remove drivers they don't use from /usr/share/vulkan/icd.d/ seems an easier and cleaner workaround .

another option which you probably won't like is to put a shell script in "etc/profile.d" that checks what graphic card vendor is installed.

something like

 if [[ $(lspci) == *"AMD/ATI"* ]]
 then
 export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json 
 else 
 export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/intel_icd.x86_64.json
 fi

just and idea.
