I wanted to switch from kernel 5.4.80-r1 to 5.10.61, but the mentioned nvidia driver does not compile for this kernel. I do not want to use a 470.* driver because switching monitor input programmatically does not work there for my gfx card. But 460.91.03 is still available in portage, so it should compile. Reproducible: Always Steps to Reproduce: 1. Try to compile nvidia driver for kernel 5.10.61 2. 3. Actual Results: Compile fails. Expected Results: Should compile. Going to attach the build log.
Created attachment 744423 [details] build.log
Seems nvidia's own fallback PAT implementation is broken with newer kernels. But it's using this fallback most likely because you don't have CONFIG_X86_PAT=y in your kernel's .config (normally this is default and only visible with EXPERT=y), please check. I'll update the ebuild to check for this option after more testing.
Yes, you are right. CONFIG_X86_PAT was not set, I don't know why. After setting this option, the driver compiled. Thanks for the quick response and help!

All versions are affected.
