Built from this Github source but still don’t see my Array

You do know that 5.9 is still an rc kernel and not officially released?
https://www.kernel.org/

Ok TY for the info. The module compiled manually but I think I need GPT partition table, I had a dmraid before which didn’t work with GPT so the raid disk is still MBR.

Downgraded to 5.4 expecting the patch would work but when I try to install the package it doesn’t see 5.4 header files, just 5.8 and 5.9. Tried with 5.8 headers and it failed to build.

I think I can’t use AMD-RAID with builtin AHCI

The headers of your active kernel need to be installed. There is a nice command allways installing the needed headers:

sudo pacman -S $(ls /boot | awk -F "-" '/^linux/ { print $1"-headers" }')
