Trying to patch the kernel with an AMDGPU color format fix [SOLVED]

This is the issue:

https://gitlab.freedesktop.org/drm/amd/-/issues/476

There's a patch linked towards the end. When I try to apply it, this happens:

Is this patch already applied to the archlinux kernel? Or am I doing something wrong?

EDIT: Here's the PKGBUILD, the only changes from default is adding this one patch.

Re: Trying to patch the kernel with an AMDGPU color format fix [SOLVED]

It looks like that patch was only tested against 6.2.0  , not later versions .

It probably needs to be rebased against 6.2.11 , which is beyond my skill level wrt kernel patches.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

The patch is applied successfully by the patch command you added then fails by the later patch command already contained in prepare.  Drop the line you added to prepare() and the kernel should then start to build.

That did it, thank you!
