drm/amdgpu: A workaround for JPEG_v4_0_3 ring test fail

2023-06-09T13:56:15+00:00

The jpeg_v4_0_3 jpeg_pitch register uses UVD_JRBC_SCRATCH0. It needs to move WREG() to after jpeg_start. Switch to a posted register write when doing the ring test to make sure the register write lands before we test the result.

These are used internally in the driver to align location based memory coherency requirements from memory allocated in the KFD with how we manage GPUVM PTEs. They are currently blocked in the GEM_CREATE IOCTL as we don't have a user right now. They are just used internally in the kernel driver for now for existing KFD memory allocations. So a change to the UAPI header, but no functional change in the UAPI.
