unofficial linux-ck repo with cpu optimized packages is ONLINE

graysky · 2021-09-05 20:45:02

I was toying with the idea of building regular kernels just with the optimizations enabled.

MischievousTomato · 2021-09-07 15:52:50

linux-pf is a kernel I found to be well performant too.
But yeah, normal kernels optimized would be great.

graysky · 2021-09-08 00:53:50

Done. Now providing generic-v2, generic-v3, and generic-v4.

% pacman -Sl repo-ck

Cool! Apologies if this has been mentioned before, but what do the different versions mean?

Dumb question, but is there a typo in the section you linked? Looks like v2 appears twice whereas I expect to see v3 in one of the rows, in the left column?

graysky · 2021-09-10 06:27:31

Nope legit typo, fixed.

cowlick · 2021-09-11 00:10:27

I can provide feedback on generic-v2. It works.

graysky · 2021-09-11 01:09:30

I'm using generic-v3 on my systems.

graysky · 2021-09-14 17:08:40

OK gang, linux-ck is back. No MuQSS, but it includes CK's hrtimer patches and the 1000 Hz tick rate:
From https://ck-hack.blogspot.com/2021/08/51 … -once.html

CK wrote:

Final word. If you want to get the most out of the mainline kernel without trying to port MuQSS, then using at least the hrtimer patches from -ck and 1000Hz should make a significant difference.

These are available again in four flavors:
generic
generic-v2
generic-v3
generic-v4

They correspond to -march= settings. See: https://wiki.archlinux.org/title/Unoffi … ed_package

I have learned about the sad news concerning linux-ck fate last week. TBH, a component very valuable of the package is the compiler optimization switches patch which I think you are the author. So if you keep maintaining it, despite what CK decides, this is a worthwhile addition.

I'm not too sure exactly what is added to it every few months or so but I do use it as well when I compile a custom RT kernel... It is very cool...

sudo pacman -Syuw linux-ck is giving this:

error: could not open file /var/lib/pacman/sync/repo-ck.db: Lzma library error: Corrupted input data
error: target not found: linux-ck

What to do about it?

glenb77 · 2021-10-02 01:36:07

same error here. did the key change or something ?

Cotton · 2021-10-02 10:10:07

FWIW
sudo pacman-key -r 5EE46C4C --keyserver hkp://pool.sks-keyservers.net && pacman-key --lsign-key 5EE46C4C
gpg: keyserver receive failed: No name

graysky · 2021-10-02 10:29:06

Problem on the host. They are "working" on it. You can manually download the packages in the meantime.

Cotton · 2021-10-02 21:12:10

Thanks - appears to be fixed now.

Not working again for about two days

graysky · 2021-11-03 21:06:33

Use a different keyserver:

# pacman-key -r 5EE46C4C --keyserver hkp://keys.gnupg.net
# pacman-key --lsign-key 5EE46C4C

Hello graysky,

I actually used the linux-lqx kernel until today. But then today I accidentally found out that this kernel does not support numa.

I found out because I was bored and wondered to which DIE my NVME disks and the GPU's (2x 1080ti, 1 AMD PRO WX3100) are connected. And the output of lstopo made me skeptical. And numactl --hardware confirmed that my system only runs in uma.

So quickly rebooted, and selected the linux-zen kernel and voila, now numa.

(And yes, I know that the lqx kernel is probably not optimal for a TR1950x system anyway )

But after that I got bored again, and kept looking for great kernels and came across linux-ck. And at the same time with the news that the linux-ck will probably no longer give. And apparently it is probably so. Since among other things in newer releases now e.g. the MuQSS Sheduler is missing.

Long speech, short sense:

Have now actually two questions.

1) Is the ck kernel still "worth it"?
and
2) I have read https://wiki.archlinux.org/title/Unoffi … ls_package, and have the following outputs:

/lib/ld-linux-x86-64.so.2 --help | grep supported
x86-64-v3 (supported, searched)
x86-64-v2 (supported, searched)
x86_64 (AT_PLATFORM; supported, searched)
tls (supported, searched)
x86_64 (supported, searched)

gcc -c -Q -march=native --help=target | grep march
-march= znver1
Known valid arguments for option "-march=":

What should I use now? I didn't find a zenver1 linux-ck package, so I guess V3?

In general, I would like to know the differences between all those.

Thanks a lot!

And sry, my English is really poor. So the text is translated with deepl.

PS:

BTW I use Arch!

(Sorry, that had to be! )

With generic-v3 kernel I still experience the docker issue I had with linux-ck-skylake with MuQSS. Launching a container ends with:

$ docker run -d -p 80:80 --name nextcloud nextcloud
33eb7bb577bca6f068405630c8b410ca3a3e86b6588221178edc000a267b9157
docker: Error response from daemon: failed to create shim: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: process_linux.go:508: setting cgroup config for procHooks process caused: bpf_prog_query(BPF_CGROUP_DEVICE) failed: invalid argument: unknown.

Now at least it's clear that MuQSS is not the culprit. So what are the differences between the vanilla kernel and generic-v3? And among these, is there any that looks suspect? Thanks.

FIreFaced · 2021-11-12 00:17:52

I'm probably screwing something up, but how do I debug the display going glitchy and the kernel just not working before systemd's init can even run?

The file host repo-ck uses fails at times, make sure the entry in pacman.conf is as follows

[repo-ck]
Server = https://mirror.lesviallon.fr/$repo/os/$arch
Server = http://repo-ck.com/$arch

EDIT: Just saw you have that lesviallon mirror. Hm, try doing pacman -Syyu and try again?

@graysky Thanks for keeping the ck kernels going!

graysky · 2022-04-14 11:43:40

Is anyone interested in testing the 5.17.y ck kernel? I'd like some broader feedback before I push it out to the AUR and to the repo. Please try it here if interested and feel free to reply to this thread with feedback, good and bad.

http://repo-ck.com/testing/

You can download a prebuilt package or build yourself.

I compiled with clang and got the following error

kernel/sysctl.c:1681:14: error: initializing 'void *' with an expression of type 'const int *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]

with gcc its warning

kernel/sysctl.c:1681:35: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
 1681 |                 .extra2         = &ten_thousand,

 1690 |                 .extra2         = &ten_thousand,

but I want to use clang for compilation
