Linux-Cacule Kernels for several architectures (armv7/aarch64 and x86_64)

General Informations

- Linux-cacule is the stable kernel
- The linux-cacule-rdb is still a expermiental kernel.At the moment not maintained, needs to be updated
- Follow the readme, the sysctl options can improve much your expierence!!!

amd64 / x86_64

# Linux 5.13.y
    - linux-cacule                         https://aur.archlinux.org/packages/linux-cacule/
    - linux-cacule-rdb                     https://aur.archlinux.org/packages/linux-cacule-rdb/
# Linux 5.12.y
    - linux-hardened-cacule                https://aur.archlinux.org/packages/linux-hardened-cacule/
# Linux 5.14-rc
    - linux-cacule-rc                      https://aur.archlinux.org/packages/linux-cacule-rc/
    - linux-cacule-rdb-rc                  https://aur.archlinux.org/packages/linux-cacule-rdb-rc/

• When building the kernel, you can edit the PKGBUILD to your prefences regarding the user specific wishes
• Also at building the kernel, you will be asked for some things like your cpu architecture, disabling debug settings for better performance, ...

aarch64/armv7h

# Linux 5.11.y
    - linux-raspberrypi4-cacule-stable      
    - linux-raspberrypi4-cacule             

Some infos for building arm devices:

-  it is automaticly collecting your architecture, so you can use the pkgbuild for armv7h/aarch64 without changes
-  All kernels are tested and working

Tips & Tricks:

You can tune the scheduler with following commands:
