Linux kernel 5.17 compatibility and patch

[birdie]

I cannot build 510.47.03 with Linux 5.17:

Anyone seen patches to fix this?

Edit:

Solved it by CONFIG_DRM_BOCHS=m which enables the missing kernel modules/support (CONFIG_DRM_TTM=m).

This rather looks like you enabled “cut unused symbols” in your kernel config. So by enabling a different drm driver they appeared in symvers.

I used the same config as for my 5.15 kernel and for some reasons DRM_TTM is no longer enabled - again, fixed it by enabling CONFIG_DRM_BOCHS=m.
