For reasons that I'm sure made perfect sense at the time we were opting to defer the iova alloc / pin on the ringbuffer until HW init time so when we moved to iova reference counting we ended up adding a reference count every time the hardware started. Not that it mattered (because the ring is always around) but it did make the debug output look odd. Allocate and pin the iova at create time instead. Signed-off-by:

For debugging purposes it is useful to assign descriptions to buffers so that we know what they are used for. Add a field to the buffer object and use that to name the various kernel side allocations which ends up looking like like this in /d/dri/X/gem: flags id ref offset kaddr size madv name 00040000: I 0 ( 1) 00000000 0000000070b79eca 00004096 memptrs vmas: [gpu: 01000000,mapped,inuse=1] 00020000: I 0 ( 1) 00000000 0000000031ed4074 00032768 ring0 Signed-off-by: -

Add a reference count to track how many times a particular chunk of iova memory is pinned (mapped) in the iomu and add msm_gem_unpin_iova to give up references. It is important to note that msm_gem_unpin_iova replaces msm_gem_put_iova because the new implicit behavior that an assigned iova in a given vma is now valid for the life of the buffer and what we are really focusing on is the use of that iova. For now the unmappings are lazy; once the reference counts go to zero they *COULD* be unmapped dynamically but that will require an outside force such as a shrinker or mm_notifiers. For now, we're just focusing on getting the counting right and setting ourselves up to be ready for the future. Signed-off-by:

Add a new function to get and pin the iova memory in one step (basically renaming the old msm_gem_get_iova function) and switch msm_gem_get_iova() to only allocate an iova but not map it in the IOMMU. This is only currently used by msm_ioctl_gem_info() since all other users of of the iova expect that the memory be immediately available. Signed-off-by:

Add headers for the 'gem' debugfs file to make it easier to remember what all the values mean and move the list of virtual address regions to the next line and add the name and map status to make it clearer what we are looking at. Signed-off-by:

Split the operation of msm_gem_get_iova into two operations: 1) allocate an iova and 2) map (pin) the backing memory int the iommu. This is the first step toward allowing memory pinning to occur independently of the iova management. Signed-off-by:

The a6xx GPU state allocates a LOT of memory. Add a bit of infrastructure to track the memory allocations in the GPU structure and delete them when the state is destroyed much the same way that devm works with the device model as a whole. This protects against the developer accidentally forgetting to add a kfree() to an ever growing list. Signed-off-by:

Instead of trying to store all the tagged buffers from a hanging submit only store the command buffers that were not imported. This cuts down on the amount of data stored in the GPU state to the base minimum of useful information. The downside is that this will make it more difficult to successfully replay a hang with just the GPU state but there isn't any reason why that functionality can't be added back in later once we've figured out how to better communicate such massive amounts of data.

Add trace events to track the progress of a GPU submission msm_gpu_submit occurs at the beginning of the submissions, msm_gpu_submit_flush happens when the submission is put on the ringbuffer and msm_submit_flush_retired is sent when the operation is retired. To make it easier to track the operations a unique sequence number is assigned to each submission and displayed in each event output so a human or a script can easily associate the events related to a specific submission.

Add infrastructure to track statistics for GPU submissions by sampling certain perfcounters before and after a submission. To store the statistics, the per-ring memptrs region is expanded to include room for up to 64 entries - this should cover a reasonable amount of inflight submissions without worrying about losing data. The target specific code inserts PM4 commands to sample the counters before and after submission and store them in the data region. The CPU can access the data after the submission retires to make sense of the statistics and communicate them to the user. Signed-off-by:

Allocate the correct buffer size for the GPU memptrs. The incorrect size hasn't affected us thus far since the incorrect size was larger than the intended size and we're still stuck on page sized granularity anyway but technically correct is the best kind of correct. Signed-off-by:

Since we removed all suspend logic from the crtc code (see patch 3/4), dpu_crtc_reset does the same things as drm_atomic_helper_crtc_reset, so let's just replace it with a call to the atomic helper. v3: added patch to patchset Reviewed-by:

Since drm core's modeset locks serialize atomic commits, we don't need to track whether or not we're in a suspended state from inside the crtc for dpu_crtc_enable/disable. This patch removes the suspend logic from the crtc and removes the relevant tracing from dpu_trace. Since we removed all calls to dpu_kms_is_suspend_state, we can remove that function and the suspend_state field of dpu_kms as well. v2: added patch to patchset v3: reworded commit body and moved deletion of dpu_kms_is_suspend_state and suspend_state to this patch Reviewed-by:

Removes the traces of the non-atomic helper calls in msm_pm_suspend/resume since we just deleted those functions (see patch 1). Also removes the drm_kms_helper_poll_disable/enable calls, since the DRM_CONNECTOR_POLL_CONNECT flag is never set so periodic polling doesn't happen anyways. v2: reorganized patch order v3: made error checks less severe Reviewed-by:

This reverts commit 9a09a423. The whole interface isn't thought through. Since this function can't fail we actually can't allocate an object to store the sync point. Sorry, I should have taken the lead on this from the very beginning and reviewed it more thoughtfully. Going to propose a new interface as a follow up change. Signed-off-by:
