I was some days in the hospital and couldnt update the kernel or anything else.

I hope you are well now, keep safe.

5.13.9-1 Changes:

Mostly these are many changes:

• Ill provide now for every kernel version also a lto/llvm version in the aur, soon i will try to implement them all together
• Cacule is now only one patch but all in one. So, normal Cacule, RDB, RDB-Autogroup,it depends on the config flags which will be used then
• First we got with auto group and rdb really bad experiences, but @Hamadmarri got it again to slove these problems.
• Also there are some new sysctl commands, ill write a readme soon.
• Then the usual patches got updated.

You will find all Kernels following mirrors compiled in x86-v1 and x86_64_v3:

Finnland 1 GBIT : https://build.cachyos.org
Germany 2.5 GBIT: https://aur.cachyos.org
Amsterdam 1 GBit: https://mirror1.cachyos.org

I think in the next 2 HRs the Kernels will be up.

Regards.

5.13.10 and upcoming 5.13.11 Changes:

• Config got complete reworked with the 5.13.11 and also some changes already in 5.13.10
• At the RDB-Kernel autgroup is now as default enabled, since its performance really good
• Kernels in the AUR and also my repo are automatically compiled with LTO, for Nvidia Users i will write a workaround to get there DKMS running for it.
• RT Kernel will be only the LTS Kernel (5.10) maintained, since most changes are getting backported and the 5.10 RT Patch gets more frequently updated
• Also we are working on a own hardened kernel, which is enhanced to the stndard Linux-hardened patch
• The README will be also soon complete reworked

[ptr1337]

Sorry, for the last issues.

For the people who compile their kernel itself we added a nice script for setting your march automatically.

Also arch-patches got updated.

Rewriting now the README.

Have fun.

[dr460nf1r3]

The update is currently compiling for Chaotic-AUR as well

[ptr1337]

5.13.12 Changes:

• There are now 2 variables to set for the CPU detection. One which is default enabled will auto detects your CPU and set the correct FLAG in the CONFIG.
• Due a request in the AUR i also included the old script, which can be enabled if you want to use the old "configure" script for the CPU March
• CPU Patches got updated
• The README.md got a little rework right now. Some things like all the general added sysctl options are missing, which can be "tuned", can improve the performance.

Hey there, first of all thank you for the kernel. It’s amazing when it works which unfortunately isn’t happening today. Please check out the following thread when you have a minute. Thanks you

Debugging current linux-cacule issues

Hey, so as of yesterday or today, problems have arisen such as no audio in Youtube and kernel errors with VirtualBox and a few other things here and there like the splash screen appearing on boot up instead of the two lines showing loading kernel ramdisk and which kernel. I am on Linux-Cacule, so just wondering if something in the kernel update recently was broken? I have restored an old snapshot where everything is working again so no issues so I don't see posting logs as useful in this situat…

Works.

[Grimy1928]

Yeah not for everyone, must be a specific issue to some hardware?

[ptr1337]

Which Kernel are you running ?
5.13.12-2 you should have no issues .

Also which CPU/Soundcard are you using?

Also QEMU i got reported that the performance is insane with this kernel.
@Soong reported that to me. Everything is tested fine.

Could be any other update create these issues? Some more informations would be nice.

[ptr1337]

5.13.12-3 Changes:

• AMD CSTATES C3 Cache will be fixed.
• GCC/CLANG CPU patch got updated, since there were some typos

Update will be later pushed if the other issue is resolved.

[ptr1337]

Its sloved. Thanks for sharing the issue.

[Grimy1928]

Thank you for fixing it. You're a very nice dev haha. Good luck with the future of the kernel and the OS and thanks for talking to me on DIscord. Glad everything is solved and working as before.

[ptr1337]

5.13.13-1 Changes:

• Cacule RDB patch got updated, some issues from the rdb version got fixed
• lru patches, bfq patches got updated

I also prepared for the upcoming 5.14 Kernel, also got some new patches in.
I already run since 3 Days the 5.14-rc7 version and im mostly really impressed about it. Feels like more smooth then 5.13.

Tomorrow it will be released i think. Also it runs so far very stable without any issues.

[Grimy1928]

No issues? Including my issue? Just pulling your leg haha, but seriously is it still an issue?

[ptr1337]

5.14.0-1 Changes:

• Added folio-mm patches, which provides a better performance
• added all other usual patches for 5.14
• added allpollingrate.patch

Right now futex2 is not running, will be added as far as a compatible patch is their, im working on it. winesync and futex are running ( proton-ge is working )

For the allpollingrate.patch you need to add options to your boot options : usbhid.poll=1 which forces to use 1000 hz on your mouse, keyboard, joystick and all other usb stuff.

Precompiled kernels are available for in my repo, also the lto compiled ones.

Just run the following script for the repo, but you need to add chaotic-aur after using the script.

wget https://build.cachyos.org/cachyos-repo.tar.xz
tar xvf cachyos-repo.tar.xz
cd repo
sudo ./cachyos-repo.sh

5.14.0-2 Changes

• Several patched added
• Soundfix, same which was before one time

With the next update will be anbox again available and futex2.

Regards

[Maldevich]

Finally. My internal laptop screen error flickering glitch is gone since 5.13. It made me stay at 5.12 or 5.10 lts

Thanks @ptr1337

[ptr1337]

5.14.0-4 Changes:

• fsync, futex2 are now working
• some config changes
• anbox is now also working again

I got finally a kernel compiled with full lto + PGO.
Performance seems very good with it, but did not benchmarked it.
The patch needs some work to be completly stable.

PGO Kernels should be compiled on his own machine. Since it needs one compile for profiling, after that the profile must be proccesed with llvm.
Then adding the profile into the PKGBUILD's source and changing some config flags.

Also a custom compiled llvm is at the moment needed.
