What is this?

pf-kernel is a desktop-oriented Linux kernel fork. Its name is by no means related to BSD Packet Filter. “pf” stands for “post-factum”, the author’s nickname.

OK, what’s there in your patchset?

Currently, pf-kernel incorporates:

• stable kernel update
• graysky’s GCC patch
• userspace-assisted KSM
• v4l2loopback device
• BBRv2
• zstd v1.5.4
• AMD EPP P-state driver with guided autonomous mode support
• DDCCI driver
• CPU parallel bringup
• random fixes here and there

This improves interactiveness and performance, saves some memory and fixes nasty bugs.

How do I get it?

The full list of all the releases, including the latest one, is available here.

But I want binary builds!

There are Arch Linux official binaries available for some architectures (64-bit only):

• generic x86_64
• x86_64_v2
• x86_64_v3
• x86_64_v4
• Intel Core 2
• Intel Silvermont
• Intel Skylake
• Intel Tiger Lake

Where is Fedora, Gentoo etc?

Some unofficial packages are maintained here:

• Gentoo

Please don’t ask me to fix or update them, I just host some links. But if you know that some other distributions also support pf-kernel, let me know.

I saw linux-pf package in AUR, is it supported?

No, since it is maintained by other people. But I still leave some links to it here:

• linux-pf with some enhancements
• linux-pf-git to be on the very edge
• linux-pf-stable-git to be in the middle of two above

I have an idea for you!

Please let me know.
