Kernels (v 5.x) and modules from Kernel.org git repositories

As of August 8, 2022, the project will cease to be developed. Thank you to all users for their willingness to use the project and bug reports.

I encourage all users to use CachyOS kernels, in the development of which I will take an active part from now on.

Kernels and modules:

• linux-aufs-git from "Linux kernel stable tree"

• linux-aufs-git from "Linux Stable -rc releases"

• linux-bfq-dev-git from "Linux kernel stable tree"

• linux-bfq-dev-git from "Linux Stable -rc releases"

• linux-uksmd-git from "Linux kernel stable tree"

• linux-uksmd-git from "Linux Stable -rc releases"

linux-aufs-git incorporates:

• AUFS / AUFS - advanced multi-layered unification filesystem

• graysky's GCC/Clang patch - version for gcc v11/clang v12

linux-bfq-dev-git incorporates:

• bfq improvements - latest fixes authored by Paolo Valente and BFQ Team

• bfq-dev - latest fixes authored by Paolo Valente and BFQ Team

• bfq-dev-lucjan - latest fixes authored by Paolo Valente and BFQ Team and forked by Piotr Gorski

• bfq-dev-lucjan-patches / bfq-dev-lucjan-patches - specific patches authored by Paolo Valente and Piotr Gorski

• bfq-lucjan / bfq-lucjan - specific patches authored by Paolo Valente and Piotr Gorski

• graysky's GCC/Clang patch - version for gcc v12/clang v13

• LL-patches / LL-patches - specific patches authored by Piotr Gorski

Some patches for BFQ conflict with patches for BFQ-dev.

To use linux-bfq-dev-git smoothly apply bfq-reverts before bfq-dev patch. Otherwise the kernel will not compile.

• bfq-reverts / bfq-reverts - specific patches authored by Piotr Gorski

linux-uksmd-git incorporates:

• UKSMD - Userspace KSM helper daemon authored by Oleksandr Natalenko

• graysky's GCC/Clang patch - version for gcc v11/clang v12

Enable bfq

For now, you can use sudo tee /sys/block/sda/queue/scheduler <<< bfq to enable "bfq".

You can also add this to file 60-schedulers.rules:

# Non-rotational disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="bfq"
# Rotational disks
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="1", ATTR{queue/scheduler}="bfq"

and run a command sudo udevadm control --reload && sudo udevadm trigger

For now, bfq is enabled by default! (since 5.0-lucjan-ll1-rc1.patch and LL-elevator-set-default-scheduler-to-bfq-for-blk-mq.patch)
