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

Can confirm also, now works on Manjaro also. Pardon my ignorance, but what is this "LTO" supposed to do anyway? Make compiling the package faster or actually make drivers performance faster?

rjahanbakhshi commented on 2024-02-01 09:06 (UTC)

Seems there are still issues with LTO so I disabled it again.

I can confirm, after disabling LTO everything works again.

If you are running arch and plasma and would like to edit the PKGBUILD, On line 124, change -D b_lto=true to -D b_lto=false

Here is the command: yay -S mesa-git --editmenu --editor kate

I can confirm, after disabling LTO everything works again.

For anyone interested do: paru -S mesa-git --fm vim

and edit PKGBUILD then set -D b_lto=true to false

deemon commented on 2024-01-31 21:53 (UTC)

@Lone_wolf yes it did, but not anymore... since Timeshifting back also rolled journald back :D But pretty much exactly that happened what ArchUsr1 commented on. Am using Plasma Wayland and after bootup there was black screen and only mouse. CTRL-ALT-F3 and logged into terminal and checked journald and it did show sddm crash.

Beiruty commented on 2024-01-31 20:28 (UTC)

The bug I am seeing is described here: https://bugzilla.redhat.com/show_bug.cgi?id=2262065

ArchUsr1 commented on 2024-01-31 18:04 (UTC)

Looks like kwin wayland is crashing since yesterday. SDDM works if it uses X11, but after login in with wayland session screen is black and only cursor is visible SDDM will crash if configured with wayland as well I've created an issue in mesa, but I'm not sure if some latest mesa update causing this issue or some package https://gitlab.freedesktop.org/mesa/mesa/-/issues/10536

Lone_Wolf commented on 2024-01-31 17:59 (UTC)

Latest comments in https://gitlab.freedesktop.org/mesa/mesa/-/issues/6376 indicate lto may still have issues.

Beiruty, I suggest you disable lto again, re-buoild and test.

I used $NINJAFLAGS="-j8" And the load went to 56 with firefox. I closed firefox and load stabilized at 24 Prior to "lto1-tran" builds, build time on my machine was 8-mins. Now, it is 17-mins. I let the build completes, and I restarted my machine, I am still seeing incomplete renderings of pixelated images such as user icons, taskmanger preview icons and flicking at the Plasma top panel. It looks like a regression.

I restored to before mesa-git upgrade.

LTO builds do increase buildtime and memory & IO resources used at buildtime in exchange for runtime performance improvements. Also ninja is known to be resource greedy .

options to mitigate the load :

  • prepend NINJAFLAGS="-j N -l N" to the build command (replace N with the number of threads you're willing to use for compiling)

  • If you have < 32 GiB memory, consider settting TMPDIR to a location on a SSD (preferably one on a different controller). This slows down the build some, but reduces the memory and IO pressure substantially.
