drm/amdgpu: fix scatter-gather mapping with user pages

2020-03-25T16:10:40Z

Calls to dma_map_sg may return less segments / entries than requested if they fall on page bounderies. The old implementation did not support this use case.

drm/amdgpu: add fbdev suspend/resume on gpu reset

2020-03-13T13:20:31Z

This can fix the baco reset failure seen on Navi10. And this should be a low risk fix as the same sequence is already used for system suspend/resume. Signed-off-by: Evan Quan Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amd/amdgpu: Fix GPR read from debugfs (v2)

2020-03-13T13:20:31Z

The offset into the array was specified in bytes but should be in terms of 32-bit words. Also prevent large reads that would also cause a buffer overread. v2: Read from correct offset from internal storage buffer.

drm/amdgpu: clean wptr on wb when gpu recovery

2020-03-05T05:50:07Z

The TDR will be randomly failed due to compute ring test failure. If the compute ring wptr & 0x7ff(ring_buf_mask) is 0x100 then after map mqd the compute ring rptr will be synced with 0x100. And the ring test packet size is also 0x100. Then after invocation of amdgpu_ring_commit, the cp will not really handle the packet on the ring buffer because rptr is equal to wptr.
