lucjan-kernels's Introduction

My own kernels. Use at your own risk.

HP 850 G3 with Sixth Gen Intel Core i3/i5/i7 optimized.
linux-lucjan varies considerably from stock kernel.

As of July 19, 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.

linux-lucjan incorporates:
Some patches for BFQ/block-stable conflict with patches for BFQ-dev/block-mainline.
To use lucjan-kernels smoothly apply ll-reverts before linux-lucjan patch. Otherwise the kernel will not compile.

Download:

git clone https://github.com/sirlucjan/lucjan-kernels.git

or

git clone https://gitlab.com/sirlucjan/lucjan-kernels.git

Install:

Testing

cd /some_path/lucjan-kernels/lucjan-kernels-testing/package_name
makepkg -srci

Unstable

cd /some_path/lucjan-kernels/lucjan-kernels-unstable/package_name
makepkg -srci

Rolling

cd /some_path/lucjan-kernels/lucjan-kernels-rolling/package_name
makepkg -srci

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)

You've been warned.

lucjan-kernels's Issues

cannot resolve "initramfs-lucjan"

I build your rolling kernel, but when I try to run
pacman -U "package_name"
I got something like this:

warning: cannot resolve "initramfs-lucjan", a dependency of "linux-lucjan-git-kernel"
:: The following package cannot be upgraded due to unresolvable dependencies:
      linux-lucjan-git-kernel

What I'm doing wrong?

UKSM and lru

Hello, sorry to bother you, I have two questions, is UKSM effective to use? Can I enable UKSM and lru at the same time?

bfq is not enabled by default on nvme disks.

Hey, thank you for maintaining the kernel.

But, I noticed that bfq does not seem to enabled by default on my pc.(OS: Arch Linux [x86_64])


# cat /sys/block/nvme0n1/queue/scheduler
[none] bfq 

# dmesg | grep -i 'io scheduler'
[    0.463912] io scheduler bfq registered

# dmesg | grep -i 'bfq'
[    0.463912] io scheduler bfq registered
[    0.463914] BFQ I/O-scheduler: BFQ-lucjan v5.14 (with cgroups support)

# journalctl -b | grep -i bfq
kernel: io scheduler bfq registered
kernel: BFQ I/O-scheduler: BFQ-lucjan v5.14 (with cgroups support)

# uname -a
Linux 5.14.6.ll43-0-lucjan #1 SMP PREEMPT Sat, 18 Sep 2021 02:01:38 +0000 x86_64 GNU/Linux

I have not changed the default config.

#
# IO Schedulers
#
# CONFIG_MQ_IOSCHED_DEADLINE is not set
# CONFIG_MQ_IOSCHED_KYBER is not set
CONFIG_IOSCHED_BFQ=y
CONFIG_BFQ_GROUP_IOSCHED=y
# CONFIG_BFQ_CGROUP_DEBUG is not set
# end of IO Schedulers

DXVK broken

For Overwatch at least, it freezes and hardlocks, changing kernels fixes the issue. No issues with native linux games, csgo runs really good compared to linux-ck.

wpis w pkgbuild

Zauwazylem ze pkgbuild (wpis wylaczajacy nume) jest taki wpis

-i -e '/CONFIG_NODES_SHIFT=6/d' \

natomiast w pliku konfiguracyjnym kernela jest wpis:

CONFIG_NODES_SHIFT=2

czyli prawdopodobnie komenda sed nie odnajdzie poprawnego wpisu w konfigu bo te dwa wiersze roznia sie cyfra 6 i 2
