Why does this package hard depend on llvm-minimal-git ?

  • performance

archlinux repo packages are build with -march=x86-64 -mtune=generic which works on lots of machines but makes limited use of modern processor capabilities. For many packages this has little impact, but with llvm my experience is different.

My local builds for llvm / mesa are done with -march=native and this has a noticeable effect on their performance.

How big the benefit of this is depends heavily on the exact hardware you use. Worse, the software setup also impacts this. The only way to find out if it benefits your system/software setup is to try it out yourself.

  • easier maintenance and troubleshooting

Since i started my first mesa trunk package late in 2010 I have maintained versions without any llvm, one llvm implementation, split versions, singular versions, versions supporting multiple llvm implementations , switch from libgl hacks libglvnd to allow mesa & nvidia to cooperate etc.

Depending on one llvm variant in a non-splitted singular version results in a simple PKGBUILD that is easy to maintain.

Troubleshooting is also much easier if maintainer uses the same llvm variant as users.

If people feel those reasons are not good enough to hard depend on llvm-minimal-git , maybe I should transfer ownership .

Why does this exist ?

Basically mesa/mesa-git build almost everything they can build.

This package tries to build just enough so everyone can use it, but disables older and/or unused components.

Check https://bbs.archlinux.org/viewtopic.php?id=261629 for a discussion about this package.

libffi has been updated, so llvm-minimal-git needs a rebuild .

After that rebuild has finished you will need to rebuild this pacakge also .

Lone_Wolf commented on 2021-10-09 12:36

Patch added to solve a build failure, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/5471

clover patch has also been commited now: https://cgit.freedesktop.org/mesa/mesa/commit/?id=d4f7337d14eb8c135a9a89dcd0e01fc93214a927

Thanks for the alert, Xenu.

Patch edited & renamed, working on lib32-mesa-minimal-git now. .

MR 12715 has been commited to main: https://cgit.freedesktop.org/mesa/mesa/commit/?id=09cf2584bdf2184a67115b4e36038bba9f3e0ff1

Though this only fixes "src/amd/llvm/ac_llvm_helper.cpp". Patching "src/gallium/frontends/clover/llvm/codegen/common.cpp" was not part of this MR.

Thank you for your work Lone_Wolf.

Patch as posted by xenu applied.

Thanks for creating it.

Created a short patch for current build issue with llvm14 (based on https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/12715)

I had an issue with opengl games freezing after a short time and causing a GPU reset (Radeon 6900XT). Same game run with zink worked fine. Downgrading llvm/clang to version 12 and rebuilding this package resolved the issue. Anyone else run into this?

Lone_Wolf commented on 2021-07-05 13:35

Depends on which functionality you need.

  • libunwind is for debugging

  • lmsensors adds graphics related sensors to lmsensors database

  • gallium-opencl enables opencl through libclc, but mainly works on polaris (like RX 580) and earlier cards.

If you feel you don't need / want that functionality, you can disable them and simplify dependencies a bit .

Oops! you're right. I cloned that one instead!

Thanks for maintaining this really! Now I want to go more minimal with only AMD stuff, should I only edit the vulkan-drivers and gallium-drivers or are there extra stuff to modify in PKGBUILD as well?
