Is there a better way to add patches to the kernel package?

[okawo80085]

Hi,

i need 2 patches added to the kernel for my vr headset to work, and im wondering if there is a better way to do it?

currently i made a copy of the 6.18 kernel package with a different name and patches added (also had to disable the no patches check) in my local void-packages repo, the diff of the thing compared to the actual kernel package looks like this:

diff -r -u linux6.18 linux6.18-bsb-fix
Only in linux6.18-bsb-fix/patches: 0001-Change-device-uvc_version-check-on-dwMaxVideoFrameSi.patch
Only in linux6.18-bsb-fix/patches: amd-bsb-dsc-fix.patch
Only in linux6.18-bsb-fix/patches: bigscreen-beyond-kernel.patch

the patches themselves are from the Linux VR Adventure wiki page on the big screen beyond (i only added the patches for amd cuz thats what i run on): https://wiki.vronlinux.org/docs/hardware/bigscreen-beyond/

so uhhh, is there a better way to do this? cuz i keep forgetting to update the package template to be in sync with the 6.18 kernel package xd

don't copy the whole template, just drop your patches in srcpkgs/linux6.18/patches, build the package, install it, and repolock linux6.18 and any subpackages

thanks! thats way more convenient!

If you remove the patch-${version}.xz you are going to build version 6.18.0.

just out of curiosity, and for completeness: if someone wants to have multiple kernels, then is there anything beyond what @okawo80085 did?
