Public bug reported:
[Impact]
We need to support new hardware from AMD and Intel, but backporting support to
oem-5.13 is very laborous and prone to errors.
[Fix]
There only sane way to add a better base for the new hw is by syncing the whole
drivers/gpu/drm directory from current 5.14. We also need to update
drivers/dma-buf and include a minor abi revert for NVIDIA.
[Test case]
Boot current and new hw from AMD & Intel with the new kernel, and also test
that NVIDIA dkms still builds.
[Where things could go wrong]
any drm driver could regress, but since v5.14 is already at rc6 this is less
likely, and for oem-5.13 we mostly care about drm/amdgpu and drm/i915 anyway.
