2024-11-04drm/amdgpu: Expose special on chip memory pools in fdinfoTvrtko Ursulin
In the past these specialized on chip memory pools were reported as system memory (aka 'cpu') which was not correct and misleading. That has since been removed so lets make them visible as their own respective memory regions.

2024-11-04drm/amdgpu: stop tracking visible memory statsYunxiang Li
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.

2024-11-04drm/amdgpu: make drm-memory-* report resident memoryYunxiang Li
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.

2024-10-08drm/amdgpu: Use drm_print_memory_stats helper from fdinfoTvrtko Ursulin
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.

2022-05-26drm/amdgpu: Convert to common fdinfo format v5Christian König
Convert fdinfo format to one documented in drm-usage-stats.rst. It turned out that the existing implementation was actually completely nonsense. The calculated percentages indeed represented the usage of the engine, but with varying time slices. So 10% usage for application A could mean something completely different than 10% usage for application B. Completely nuke that and just use the now standardized nanosecond interface. v2: drop the documentation change for now, nuke percentage calculation v3: only account for each hw_ip, move the time_spend to the ctx mgr. v4: move general ctx changes into separate patch, rework the fdinfo to ctx_mgr interface so that all usages are calculated at once, drop some unecessary and dangerous refcount dance. v5: add one more comment how we calculate the time spend Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Shashank Sharma <shashank.sharma@amd.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
