drm/amdgpu: Fix some unload driver issues

2021-05-12T06:37:20+00:00

[ Upstream commit bb0cd09be45ea457f25fdcbcb3d6cf2230f26c46 ] When unloading driver after killing some applications, it will hit sdma flush tlb job timeout which is called by ttm_bo_delay_delete. So to avoid the job submit after fence driver fini, call ttm_bo_lock_delayed_workqueue before fence driver fini. And also put drm_sched_fini before waiting fence.

commit 9aa26019c1a60013ea866d460de6392acb1712ee upstream. During system hibernation suspend still need un-gate gfx CG/PG firstly to handle HW status check before HW resource destory.

drm/amdgpu: fix shutdown and poweroff process failed with s0ix

2021-03-04T11:15:23+00:00

commit b092b19602cfd47de1eeeb3a1b03822afd86b136 upstream. In the shutdown and poweroff opt on the s0i3 system we still need un-gate the gfx clock gating and power gating before destory amdgpu device.

drm/amdgpu: fix a GPU hang issue when remove device

2021-01-06T21:17:27+00:00

When GFXOFF is enabled and GPU is idle, driver will fail to access some registers. Therefore change to disable power gating before all access registers with MMIO. Dmesg log is as following: amdgpu 0000:03:00.0: amdgpu: amdgpu: finishing device. amdgpu: cp queue pipe 4 queue 0 preemption failed amdgpu 0000:03:00.0: amdgpu: failed to write reg 2890 wait reg 28a2 amdgpu 0000:03:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706 amdgpu 0000:03:00.0: amdgpu: failed to write reg 2890 wait reg 28a2 amdgpu 0000:03:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706 Signed-off-by: Dennis Li Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher
