Clang AutoFDO & Propeller Optimization Support Sent In For Linux 6.13: 5~10% More Performance

[Draget]

your garbage distro fails on all kinds of fronts.

Ah, such good, old, classic and fish-hungry, disgruntled troll deserves a good old *LOL*. Seems to be his thing, looking at the posts.


Anyways:
It's interesting to see such patches from Google. If they claim that they have tested the patches and seen performance benefits, it means they have done so across millions of devices. I hope the tooling gets picked up by more distros.

The best black friday present :P

Really glad to see AutoFDO merged, which makes it easier for distribution and users to implement this.
The PKGBUILD Integration in CachyOS is more or less done and simplifies the process. We also aim the provide the default "linux-cachyos" optimized with AutoFDO with 6.12.2, since the testing in the community with the current testing kernel goes quite well.

Pretty excited when Arch pushes LLVM 19 to their repository, so that I can also work on propeller optimization.

A GCC implementation for AutoFDO and the kernel would be really cool, but the complete "create_gcov" tool from the autofdo repository seems more or less unmaintained, and the autofdo maintainer asked GCC to pick this up into the GCC tree, but there didnt happen anything yet.

Phoronix: Clang AutoFDO & Propeller Optimization Support Sent In For Linux 6.13: 5~10% More Performance

Making for an even more exciting Black Friday is the Kbuild pull request submitted today for the near-over Linux 6.13 merge window... And it includes Clang Auto Feedback Directed Optimization (AutoFDO) support for kernel builds as well as Clang's Propeller...
