drm/msm: Drop priv->lastctx

2024-10-17T13:07:48+00:00

[ Upstream commit 1d054c9b8457b56a651109fac21f56f46ccd46b2 ] cur_ctx_seqno already does the same thing, but handles the edge cases where a refcnt'd context can live after lastclose. So let's not have two ways to do the same thing.

drm/msm: Add priv->mm_lock to protect active/inactive lists

[ Upstream commit d984457b31c4c53d2af374d5e78b3eb64debd483 ] Rather than relying on the big dev->struct_mutex hammer, introduce a more specific lock for protecting the bo lists.

drm/msm: Allow a5xx to mark the RPTR shadow as privileged

2020-09-15T17:47:44+00:00

Newer microcode versions have support for the CP_WHERE_AM_I opcode which allows the RPTR shadow memory to be marked as privileged to protect it from corruption. Move the RPTR shadow into its own buffer and protect it it if the current microcode version supports the new feature. We can also re-enable preemption for those targets that support CP_WHERE_AM_I. Start out by preemptively assuming that we can enable preemption and disable it in a5xx_hw_init if the microcode version comes back as too old. Signed-off-by: Jordan Crouse 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: Add a context pointer to the submitqueue

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

Each submitqueue is attached to a context. Add a pointer to the context to the submitqueue at create time and refcount it so that it stays around through the life of the queue. Co-developed-by: Rob Clark Signed-off-by: Jordan Crouse Signed-off-by: Rob Clark Reviewed-by: Bjorn Andersson

drm/msm: Set adreno_smmu as gpu's drvdata

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

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: 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
