10 daysdrm/amdgpu: use hmm_pfns instead of array of pagesSunil Khatri
we dont need to allocate local array of pages to hold the pages returned by the hmm, instead we could use the hmm_range structure itself to get to hmm_pfn and get the required pages directly. This avoids call to alloc/free quite a lot.

2025-09-01drm/amdgpu: give each kernel job a unique idPierre-Eric Pelloux-Prayer
Userspace jobs have drm_file.client_id as a unique identifier as job's owners. For kernel jobs, we can allocate arbitrary values - the risk of overlap with userspace ids is small (given that it's a u64 value). In the unlikely case the overlap happens, it'll only impact trace events. Since this ID is traced in the gpu_scheduler trace events, this allows to determine the source of each job sent to the hardware. To make grepping easier, the IDs are defined as they will appear in the trace output.

2024-12-19drm/amdgpu: track bo memory stats at runtimeYunxiang Li
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.

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.

For better performance during VRAM access for debugged processes, do read/write copies over SDMA. In order to fulfill post mortem debugging on a broken device, fallback to stable MMIO access when gpu recovery is disabled or when job submission time outs are set to max. Failed SDMA access should automatically fall back to MMIO access. Use a pre-allocated GTT bounce buffer pre-mapped into GART to avoid page-table updates and TLB flushes on access.

2021-05-26drm/amdgpu: Implement mmap as GEM object functionThomas Zimmermann
Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. This change resolves several inconsistencies between regular mmap and prime-based mmap. The vm_ops field in vma is now set for all mmap'ed areas. Previously it way only set for regular mmap calls, prime-based mmap used TTM's default vm_ops. The function amdgpu_verify_access() is no longer being called and therefore removed by this patch. As a side effect, amdgpu_ttm_vm_ops and amdgpu_ttm_fault() are now implemented in amdgpu's GEM code. v4: * rebased v3: * rename mmap function to amdgpu_gem_object_mmap() (Christian) * remove unnecessary checks from mmap (Christian) v2: * rename amdgpu_ttm_vm_ops and amdgpu_ttm_fault() to amdgpu_gem_vm_ops and amdgpu_gem_fault() (Christian) * the check for kfd_bo has meanwhile been removed Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210525151055.8174-3-tzimmermann@suse.de
2021-05-21drm/amdgpu: Add new placement for preemptible SG BOsFelix Kuehling
SG BOs such as dmabuf imports and userptr BOs do not consume system resources directly. Instead they point to resources owned elsewhere. They typically get evicted by DMABuf move notifiers of MMU notifiers. If those notifiers don't need to wait for hardware fences (i.e. the SG BOs are used in a preemptible context), then we don't need to limit them to the GTT size and we don't need TTM to evict them. Create a new placement for such preemptible SG BOs that does not impose artificial size limits and TTM evictions.
