Unofficial user repositories/Repo-ck
Repo-ck is an unofficial Arch Linux repository hosting generic and CPU-optimized kernels and support packages, featuring MuQSS (pronounced mux) and rest of the ck patchset by Con Kolivas. It has been in operation since 2011 and is maintained by graysky.
Add the repo to
/etc/pacman.conf under the Arch official repositories:
[repo-ck] Server = http://repo-ck.com/$arch
Sign graysky's key:
# pacman-key -r 5EE46C4C --keyserver hkp://pool.sks-keyservers.net && pacman-key --lsign-key 5EE46C4C
aviallon hosts a mirror with better bandwidth and stability, synchronized every 6 hours. You can add it to your
[repo-ck] Server = https://mirror.lesviallon.fr/$repo/os/$arch Server = http://repo-ck.com/$arch
Update your sync database and install the chosen kernel variant (see below for available variants):
# pacman -Syu linux-ck
Update Boot Loader Config
If you are using grub with a common setup, then you can update its config by running this command:
# grub-mkconfig -o /boot/grub/grub.cfg
The official Arch Linux kernel provides a generic package which is built for the x86_64 architecture that will run on any compatible x86_64 CPU. Repo-ck also hosts a generic version of linux-ck, and two other generic packages which are targeted at newer x86-64 hardware. Finally, selected versions of model-specific packages are offered. Model specific packages should offer the highest level of tuning and performance. See #Selecting the correct CPU optimized package below for more.
|Brand||Group Alias||Description||Build flags enabled by patchset|
|Any||ck-generic||x86-64 generic kernel good for any supported CPU||-march=x86-64|
|ck-generic-v2||x86-64-v2 generic kernel good for any supported CPU||-march=x86-64-v2|
|ck-generic-v3||x86-64-v3 generic kernel good for any supported CPU||-march=x86-64-v3|
|Intel||ck-nehalem||Intel 1st Generation Core i3/i5/i7-family||-march=nehalem|

|ck-zen3||CPUs based on AMD 4th Gen Ryzen cores||-march=znver3|
Selecting the correct CPU optimized package
If a model specific kernel is not offered, users should select one of the three generic packages that is best matched to the specific hardware. To tell which generic package is best, simply run:
$ /lib/ld-linux-x86-64.so.2 --help | grep supported
x86-64-v3 (supported, searched) is in the output, use the ck-generic-v3 group. If only
x86-64-v2 (supported, searched) is in the output, use the ck-generic-v2 group. If neither are in the output, use the ck-generic group.
Those wanting CPU-specific optimized packages can run the following command (assuming thatis installed):
$ gcc -c -Q -march=native --help=target | grep march
-march is what GCC would use natively. Refer to the table above for a mapping of this value to the correct group; again, not every possible value will have a specific group.

Downloads interrupt regularly
Graysky is using Go Daddy as his web host. Some of the transfers from their poorly implemented server end in an incomplete transfer. To combat this, list the repository address multiple times and pacman will automatically try the next available server.
