Those interested in profile-guided optimization may try a time-consuming process.

  1. Make instrumented package:
    • Set environment variable or edit PKGBUILD: _build_instrumented=true
    • Resulting package: pcsx2-instrumented-avx-git
  2. Create raw profiles using instrumented package.
    • LLVM_PROFILE_FILE="default_%9m.profraw" pcsx2-qt
    • Use a "representative" sample of roms.
    • After 9 runs, profraw files will be overwritten.
  3. Process profiles:
    • llvm-profdata merge -output=pcsx2-avx-git.profdata *.profraw
  4. Rebuild package.
    • Put pcsx2-avx-git.profdata in same folder with PKGBUILD.
    • Look for message: "Compiling with profile-guided optimization."
    • Profile can be reused. Re-profile when there are too many "function control flow change" warnings.
    • Resulting package: pcsx2-avx-git

By default, this package targets x86-64-v3 instructions (avx/avx2). Performance benefit over standard builds is probably minimal because of dynamic dispatch.

Other microarchitecture levels (v2, v3, v4) may also work by editing some config files.

  • makepkg.conf — CARCH="x86_64_v4"
  • pacman.conf — Architecture = auto x86_64 x86_64_v2 x86_64_v3 x86_64_v4
  • /usr/share/devtools/setarch-aliases.d/x86_64_v4 — Contents: x86_64

Problems:

  • Try building in a clean chroot.
  • Try other packages. Try the upstream AppImage.
  • Comment or flag for packaging issues.
    • Avoid flagging and commenting at the same time for the same issue.
    • Flag for common issues with standard solutions, like submodule updates, depends adjustments, fixing typos.
    • Comment for issues requiring explanation or debugging.
    • Use a pastebin for blocks of text more than a few lines.

@xiota. Now is building ok.

After I installed pcsx2-latest-bin and reinstalled this package the games are starting but with graphics error and that error message in the log is still there. Strange.

And I'm always deleting the mesa cache.

@xiota pcsx2-latest-bin is working.

I hope it gets fixed, but I think the OpenGL renderer is better than Vulkan on my machine.

@rodrigo21 A recent git commit broke it. While I look at it, can you see if you get the Failed to find function shaderc_compilation_status_to_string error with pcsx2-latest-bin?

I'm getting this error when building in a clean chroot: /build/pcsx2-avx-git/src/google.shaderc/third_party/spirv-tools/source/opcode.cpp:726:19: error: no member named 'OpExtInstWithForwardRefs' in 'spv::Op'; did you mean 'OpExtInstWithForwardRefsKHR'?

The previous version builds fine.
