2021-12-17drm/amdgpu: introduce new amdgpu_fence object to indicate the job embedded fenceHuang Rui
The job embedded fence donesn't initialize the flags at dma_fence_init(). Then we will go a wrong way in amdgpu_fence_get_timeline_name callback and trigger a null pointer panic once we enabled the trace event here. So introduce new amdgpu_fence object to indicate the job embedded fence.

2021-08-20drm/amdgpu: Cancel delayed work when GFXOFF is disabledMichel Dänzer
schedule_delayed_work does not push back the work if it was already scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms after the first time GFXOFF was disabled and re-enabled, even if GFXOFF was disabled and re-enabled again during those 100 ms. This resulted in frame drops / stutter with the upcoming mutter 41 release on Navi 14, due to constantly enabling GFXOFF in the HW and disabling it again (for getting the GPU clock counter). To fix this, call cancel_delayed_work_sync when the disable count transitions from 0 to 1, and only schedule the delayed work on the reverse transition, not if the disable count was already 0. This makes sure the delayed work doesn't run at unexpected times, and allows it to be lock-free. v2: * Use cancel_delayed_work_sync & mutex_trylock instead of mod_delayed_work. v3: * Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König) v4: * Fix race condition between amdgpu_gfx_off_ctrl incrementing adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off checking for it to be 0 (Evan Quan) Cc: stable@vger.kernel.org Reviewed-by: Evan Quan <evan.quan@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> # v3 Acked-by: Christian König <christian.koenig@amd.com> # v3 Signed-off-by: Michel Dänzer <mdaenzer@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2021-08-05drm/amdgpu: avoid over-handle of fence driver fini in s3 test (v2)Guchun Chen
In amdgpu_fence_driver_hw_fini, no need to call drm_sched_fini to stop scheduler in s3 test, otherwise, fence related failure will arrive after resume. To fix this and for a better clean up, move drm_sched_fini from fence_hw_fini to fence_sw_fini, as it's part of driver shutdown, and should never be called in hw_fini. v2: rename amdgpu_fence_driver_init to amdgpu_fence_driver_sw_init, to keep sw_init and sw_fini paired.

Fence driver was enabled per ring when sw init on per IP block before. Change to enable all the fence driver at the same time after amdgpu_device_ip_init finished. Rename some function related to fence to make it reasonable for read.

2021-07-23drm/amdgpu: Clear doorbell interrupt status for Sienna CichlidChengzhe Liu
On Sienna Cichlid, in pass-through mode, if we unload the driver in BACO mode(RTPM), then the kernel would receive thousands of interrupts. That's because there is doorbell monitor interrupt on BIF, so KVM keeps injecting interrupts to the guest VM. So we should clear the doorbell interrupt status after BACO exit. v2: Modify coding style and commit message Signed-off-by: Chengzhe Liu <ChengZhe.Liu@amd.com> Reviewed-by: Luben Tuikov <luben.tuikov@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2021-07-23drm/amd/amdgpu: consider kernel job always not guiltyJingwen Chen
[Why] Currently all timedout job will be considered to be guilty. In SRIOV multi-vf use case, the vf flr happens first and then job time out is found. There can be several jobs timeout during a very small time slice. And if the innocent sdma job time out is found before the real bad job, then the innocent sdma job will be set to guilty. This will lead to a page fault after resubmitting job.
