Updated cacule to cacule-rev2
switched back to 1000Hz as default, 2000 Hz can be still used if compiling with the PKGBUILD
zstd module compression removed until mkinitcpio will be updated into mainstream; thanks to @anon44840303
Added 2000HZ as an option
Added Responsive wakup/new task to be placed in a CPU with least Interactive score (to balance out interactive tasks among cpus)
Added Interactivity levels mechanism
Increased the precision of lifetime normalize from x8 to x1024
Decoupled se.vruntime from cn.vruntime
kernel.sched_nr_fork_threshold=0
kernel.sched_fake_interactive_win_time_ms=1000
You can set kernel.sched_nr_fork_threshold to your threads -1
Example: I have a Intel i8700k with 6 Cores but 12 Threads because SMT, so the value would be 11 to set.
If the value is set to kernel.sched_nr_fork_threshold=0 ; the scheduler will auto detect your cpu and set the value with ' "x" -1 '
Kernel will be deployed soon to the Chaotic-AUR, Skylake build is as always available on my server.
Regards!

I'm not a gamer but using this kernel with kde/compiz and the 99-sysctl-cacule.conf tweaks above and my amd ryzen 9 garuda system flies. any plans for a linux-cacule-zen2? (just asking lol)

Why would you run kde with compiz?

because I prefer its desktop effects and because i can.

You can easily compile the kernel with zen2 gcc optimizing yourself.
Maybe add some hours then I can add some amd fixes and some other things will be updated and fixed.

stripped the used config and removed things which are not needed
disabled bpf preloading --> grub booting error fixed
reverted the previous update since it seems to be perform on every system different and not stable
disabled NO_HZ_FULL
decreased preemption latency to 2ms
since there were many changes the last time at cacule's patch, i decided to create extra "testing-kernel" which include some experimental things
its for a better overview feedback to improve the kernel
The readme will be updated and also the first post for some sysctl config values.
Both kernels are already deployed to the chaotic-aur and the skylake build variant can be found at my fileserver https://ptr1337.dev
Would be good if users want to test also the testing kernel to get a more feedback due improvements or decreasedments or bugs.
Regards.

Feedback from me (Main linux-cacule tester)
Desktop Environment smooth without micro lags, KVM machines runs very well.
CacULE 5.12.2-6 looks solid, stable and I recommend compile kernel for your CPU architecture.

Hey,
It got updated now to 5.12.3 and got also several changes in the config.
Are you using grub or systemd-boot ?
Did you got any error or anything else ?

Not at all. It just threw me rootfs

Did you reintall the Kernel from the chaotic aur ?
Have you done after mkinitcpip -P ?
also grub mkconfig is needed.
i dont use garuda, i dont know their behavuour

Both of these commands happen automatically after installing a kernel using pacman hooks, so that shouldn't be an issue

I'm not sure if it true, because I remember scenario when I missed use sudo mkinitcpio -P and i faced boot issues.
I always write following commands after any kernel, drivers changes.sudo mkinitcpio -Psudo grub-mkconfig -o /boot/grub/grub.cfgsudo bootctl update
EDIT:linux-cacule on Garuda works perfectly.

Yep
Yep, I did that.
Anyways, I will delete all the other kernels except zen and reinstall in cleaner way…

Wait, error is
mount: /new_root : can't find UUID= 306Bf <some long UUID>
You are now being dropped into an emergency shell.
sh : can't access tty: job control turned off
Seems like your grub didnt created the correct cofnig.
so far every tester didnt got that problem.

For those who can’t remember this long formula, like me
sudo update-grub
