drm/msm: Fix premature purging of BO

2020-09-22T15:28:15+00:00

In the case where we have a back-to-back submission that shares the same BO, this BO will be prematurely moved to inactive_list while retiring the first submit. But it will be still part of the second submit which is being processed by the GPU. Now, if the shrinker happens to be triggered at this point, it will result in a premature purging of this BO. To fix this, we need to refcount BO while doing submit and retire. Then, it should be moved to inactive list when this refcount becomes 0. Signed-off-by: Akhil P Oommen Signed-off-by: Rob Clark

drm/msm: Show process names in gem_describe

2020-09-12T17:48:32+00:00

In $debugfs/gem we already show any vma(s) associated with an object. Also show process names if the vma's address space is a per-process address space. Signed-off-by: Rob Clark Reviewed-by: Jordan Crouse Reviewed-by: Bjorn Andersson

drm/msm: Add support for private address space instances

2020-09-12T17:48:32+00:00

Add support for allocating private address space instances. Targets that support per-context pagetables should implement their own function to allocate private address spaces. The default will return a pointer to the global address space. Signed-off-by: Jordan Crouse Signed-off-by: Rob Clark Reviewed-by: Bjorn Andersson

drm/msm: Drop context arg to gpu->submit()

2020-09-12T17:45:56+00:00

Now that we can get the ctx from the submitqueue, the extra arg is redundant. Signed-off-by: Jordan Crouse [split out of previous patch to reduce churny noise] Signed-off-by: Rob Clark Reviewed-by: Bjorn Andersson

drm/msm: Set adreno_smmu as gpu's drvdata

2020-09-12T17:45:56+00:00

This will be populated by adreno-smmu, to provide a way for coordinating enabling/disabling TTBR0 translation. Signed-off-by: Rob Clark Reviewed-by: Jordan Crouse Reviewed-by: Bjorn Andersson

drm/msm/gpu: Add dev_to_gpu() helper

2020-09-12T17:45:56+00:00

In a later patch, the drvdata will not directly be 'struct msm_gpu *', so add a helper to reduce the churn. Signed-off-by: Rob Clark Reviewed-by: Jordan Crouse Reviewed-by: Bjorn Andersson

drm/msm/gpu: Add GPU freq_change traces

2020-09-09T22:25:53+00:00

Technically the GMU specific one is a bit redundant, but it was useful to track down a bug. Signed-off-by: Rob Clark Reviewed-by: Jordan Crouse

drm/msm: Enable expanded apriv support for a650

2020-09-04T19:14:07+00:00

a650 supports expanded apriv support that allows us to map critical buffers (ringbuffer and memstore) as as privileged to protect them from corruption. Cc: stable@vger.kernel.org Signed-off-by: Jordan Crouse Signed-off-by: Rob Clark

drm: msm: a6xx: send opp instead of a frequency

2020-07-31T13:46:15+00:00

This patch changes the plumbing to send the devfreq recommended opp rather than the frequency. Also consolidate and rearrange the code in a6xx to set the GPU frequency and the icc vote in preparation for the upcoming changes for GPU->DDR scaling votes.
