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

First, llvm / lib32-llvm , clang / lib32-clang and their svn counterparts are only needed at build time. at runtime llvm-libs/ lib32-llvm-libs and their svn counterparts are all that's needed.

In order to figure out what is needed, check the provides lines of the *-git PKGBUILDS.

provides=('mesa' 'vulkan-intel' 'vulkan-radeon' 'libva-mesa-driver' 'mesa-vdpau' 'vulkan-driver' 'opencl-mesa' 'opengl-driver' 'opencl-driver') opengl-driver is supplied by mesa opencl-driver is supplied by opencl-mesa vulkan-driver is supplied by vulkan-intel & vulkan-radeon

to get full mesa-git functionality with extra packages you need to install mesa vulkan-intel vulkan-radeon libva-mesa-driver mesa-vdpau opencl-mesa

Use the same method for lib32-mesa.

After reverting to stable mesa, make sure to re-start X or reboot . run 'glxinfo | grep -i opengl' from an X-terminal to verify the switch has worked (glxinfo32 for lib32)

I would like to return to stable mesa but am having trouble doing so.

I tried pacman -S vulkan-radeon lib32-vulkan-radeon lib32-mesa mesa lib32-llvm-libs llvm-libs lib32-llvm llvm clang but Steam fails to launch with "Main.cpp (332) : Assertion Failed: Fatal Error: glXChooseVisual failed" and Dolphin Emulator will tell me "Failed to create shared context for shader compiling." a couple times before it boots.

How do I return to completely stock stable mesa after having installed mesa-git?

libedit error was caused by llvm-libs-svn, has been fixed there.

After investigating I've found libxrandr is a required makedepend, added that.

Thought 'llvm-config --version' shows '8.0.0svn', during config it fails not finding llvm-config >= 6.0.0. Anyone else having this? I'm building from a clean chroot...

EDIT: Nevermind. For some reason on clean chroot llvm-svn is not installing libedit...

EDIT#2: xrandr seems to be required for building mesa-git thought.

Check the last paragraph of the sticky comment, "how to update"

Incase you're already using the llvm-svn unofficial repo, building just mesa-git should take 10-30 minutes .

How to update mesa-git without have to remove it and build again? because building from the beginning takes about 9 hours!

Lone_Wolf commented on 2018-10-26 12:09 (UTC) (edited on 2018-10-26 12:10 (UTC) by Lone_Wolf)

I guess you're referring to the patches mentioned here : https://www.phoronix.com/scan.php?page=news_item&px=DXVK-Transform-Feedback ?

I've tried to follow the thread on mesa-dev, but there are several patchsets involved and the consensus appears to be more testing is needed.

Also looking at commits by Samuel Pitoiset to mesa-git,

https://cgit.freedesktop.org/mesa/mesa/log/?qt=grep&q=samuel+pitoiset

there's no sign yet of VK_EXT_Transform making it in.

You can try subscribing to mesa-dev to follow development or check cgit regularly.

torbido commented on 2018-10-25 14:20 (UTC)

No, I am just waiting for the RADV patches for VK_EXT_transform_feedback to land on Mesa 18.3. I heard there will be an update on next Wednesday 10/31.
