drm/amdgpu: check tiling flags when creating FB on GFX8-

2021-10-07T05:53:09+00:00

commit 98122e63a7ecc08c4172a17d97a06ef5536eb268 upstream. On GFX9+, format modifiers are always enabled and ensure the frame-buffers can be scanned out at ADDFB2 time. On GFX8-, format modifiers are not supported and no other check is performed. This means ADDFB2 IOCTLs will succeed even if the tiling isn't supported for scan-out, and will result in garbage displayed on screen [1]. Fix this by adding a check for tiling flags for GFX8 and older. The check is taken from radeonsi in Mesa (see how is_displayable is populated in gfx6_compute_surface). Changes in v2: use drm_WARN_ONCE instead of drm_WARN (Michel) [1]: https://github.com/swaywm/wlroots/issues/3185 Signed-off-by: Simon Ser Acked-by: Michel Dänzer Cc: Alex Deucher Cc: Harry Wentland Cc: Nicholas Kazlauskas Cc: Bas Nieuwenhuizen Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: force exit gfxoff on sdma resume for rmb s0ix

2021-10-07T05:53:09+00:00

commit 26db706a6d77b9e184feb11725e97e53b7a89519 upstream. In the s2idle stress test sdma resume fail occasionally,in the failed case GPU is in the gfxoff state.This issue may introduce by firmware miss handle doorbell S/R and now temporary fix the issue by forcing exit gfxoff for sdma resume.

drm/amdgpu: stop scheduler when calling hw_fini (v2)

2021-10-07T05:53:05+00:00

[ Upstream commit f7d6779df642720e22bffd449e683bb8690bd3bf ] This gurantees no more work on the ring can be submitted to hardware in suspend/resume case, otherwise a potential race will occur and the ring will get no chance to stay empty before suspend. v2: Call drm_sched_resubmit_job before drm_sched_start to restart jobs from the pending list.

drm/amdgpu: avoid over-handle of fence driver fini in s3 test (v2)

2021-10-07T05:53:05+00:00

[ Upstream commit 067f44c8b4590c3f24d21a037578a478590f2175 ] 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.

drm/amdgpu: adjust fence driver enable sequence

[ Upstream commit 8d35a2596164c1c9d34d4656fd42b445cd1e247f ] 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.

drm/amdgpu: Fixes to returning VBIOS RAS EEPROM address

2021-09-26T12:10:23+00:00

[ Upstream commit a6a355a22f7a0efa6a11bc90b5161f394d51fe95 ] 1) Generalize the function--if the user didn't set i2c_address, still return true/false to indicate whether VBIOS contains the RAS EEPROM address. This function shouldn't evaluate whether the user set the i2c_address pointer or not. 2) Don't touch the caller's i2c_address, unless you have to--this function shouldn't have side effects. 3) Correctly set the function comment as a kernel-doc comment.
