drm/amdgpu: track bo memory stats at runtime

2024-12-19T15:56:28Z

Before, every time fdinfo is queried we try to lock all the BOs in the VM and calculate memory usage from scratch. This works okay if the fdinfo is rarely read and the VMs don't have a ton of BOs. If either of these conditions is not true, we get a massive performance hit. In this new revision, we track the BOs as they change states. This way when the fdinfo is queried we only need to take the status lock and copy out the usage stats with minimal impact to the runtime performance. With this new approach however, we would no longer be able to track active buffers.

drm/amdgpu: remove unused function parameter

2024-12-19T15:56:25Z

amdgpu_vm_bo_invalidate doesn't use the adev parameter and not all callers have a reference to adev handy, so remove it for cleanliness.

drm/amdgpu: Update the variable name to dma_buf

2024-12-10T15:26:48Z

Instead of fixing the warning for missing variable its better to update the variable name to match with the style followed in the code. This will fix the below mentioned warning: warning: Function parameter or struct member 'dbuf' not described in 'amdgpu_bo_create_isp_user' warning: Excess function parameter 'dma_buf' description in 'amdgpu_bo_create_isp_user' Signed-off-by: Sunil Khatri Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amd/amdgpu: Add support for isp buffers

2024-12-10T15:26:45Z

Add support to create user BOs with MC address for isp using the dma-buf handle exported for the buffers allocated from system memory in isp driver. Export amdgpu_bo_create_kernel() and amdgpu_bo_free_kernel() as well for isp to allocate GTT internal buffers required for fw to run.

drm/amdgpu: Stop reporting special chip memory pools as CPU memory in fdinfo

2024-11-04T16:32:47Z

So far these specialized on chip memory pools were reported as system memory (aka 'cpu') which is not correct and misleading. Lets remove that and consider later making them visible as their own thing. Signed-off-by: Tvrtko Ursulin Suggested-by: Christian König Cc: Yunxiang Li Cc: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: stop tracking visible memory stats

2024-11-04T16:32:40Z

Since on modern systems all of vram can be made visible anyways, to simplify the new implementation, drops tracking how much memory is visible for now. If this is really needed we can add it back on top of the new implementation, or just report all the BOs as visible.

drm/amdgpu: make drm-memory-* report resident memory

2024-11-04T16:30:58Z

The old behavior reports the resident memory usage for this key and the documentation say so as well. However this was accidentally changed to include buffers that was evicted.

drm/amdgpu: Use drm_print_memory_stats helper from fdinfo

2024-10-08T13:43:25Z

Convert fdinfo memory stats to use the common drm_print_memory_stats helper. This achieves alignment with the common keys as documented in drm-usage-stats.rst, adding specifically drm-total- key the driver was missing until now. Additionally I made the code stop skipping total size for objects which currently do not have a backing store, and I added resident, active and purgeable reporting. Legacy keys have been preserved, with the outlook of only potentially removing only the drm-memory- when the time gets right. The example output now looks like this: pos: 0 flags: 02100002 mnt_id: 24 ino: 1239 drm-driver: amdgpu drm-client-id: 4 drm-pdev: 0000:04:00.0 pasid: 32771 drm-total-cpu: 0 drm-shared-cpu: 0 drm-active-cpu: 0 drm-resident-cpu: 0 drm-purgeable-cpu: 0 drm-total-gtt: 2392 KiB drm-shared-gtt: 0 drm-active-gtt: 0 drm-resident-gtt: 2392 KiB drm-purgeable-gtt: 0 drm-total-vram: 44564 KiB drm-shared-vram: 31952 KiB drm-active-vram: 0 drm-resident-vram: 44564 KiB drm-purgeable-vram: 0 drm-memory-vram: 44564 KiB drm-memory-gtt: 2392 KiB drm-memory-cpu: 0 KiB amd-memory-visible-vram: 44564 KiB amd-evicted-vram: 0 KiB amd-evicted-visible-vram: 0 KiB amd-requested-vram: 44564 KiB amd-requested-visible-vram: 11952 KiB amd-requested-gtt: 2392 KiB drm-engine-compute: 46464671 ns v2: * Track purgeable via AMDGPU_GEM_CREATE_DISCARDABLE.
