Thanks for mentioning!

Awesome! But I don't see a kernel update for exisiting users (like me). Is this only available for new users?

If you are on 6.11.7, then it is fine. Im generally writining into the changelog some fundamental changes of the kernel since the last release.
Most of the testing and communication happens in the discord and forum, but many users might do not use these and the blog gives a good way to present, what has been changed over the months.

sudo pacman -Syu is enough most at the time

The AutoFDO Kernel is available for x86-64-v3, x86-64-v4 and Zen4 users. We dont know, if we keep it up for all, since it is a quite long process to do the profiling for each architecture.

Where are the thp splitting patches located? I want to apply them to my local kernel as well but Google only gives me patches from 2022.
