drm/amd/amdgpu: add error handling to amdgpu_virt_read_pf2vf_data

2021-01-25T22:46:48+00:00

[Why] when vram lost happened in guest, try to write vram can lead to kernel stuck. [How] When the readback data is invalid, don't do write work, directly reschedule a new work. Signed-off-by: Jingwen Chen Reviewed-by: Monk Liu Signed-off-by: Alex Deucher

drm/amd/amdgpu: remove redundant flush_delayed_work

2021-01-20T21:38:17+00:00

When using cancel_delayed_work_sync, there's no need to flush_delayed_work first. This sequence can lead to a redundant loop of work executing. Signed-off-by: Jingwen Chen Reviewed-by: Monk Liu Signed-off-by: Alex Deucher

drm/amdgpu/sriov Stop data exchange for wholegpu reset

2021-01-14T04:47:39+00:00

[Why] When host trigger a whole gpu reset, guest will keep waiting till host finish reset. But there's a work queue in guest exchanging data between vf&pf which need to access frame buffer. During whole gpu reset, frame buffer is not accessable, and this causes the call trace. [How] After vf get reset notification from pf, stop data exchange.
