accel/amdxdna: Add per-process BO memory usage query support

2026-03-25T18:41:24Z

Add support for querying per-process buffer object (BO) memory usage through the amdxdna GET_ARRAY UAPI. Introduce a new query type, DRM_AMDXDNA_BO_USAGE, along with struct amdxdna_drm_bo_usage to report BO memory usage statistics, including heap, total, and internal usage. Track BO memory usage on a per-client basis by maintaining counters in GEM open/close and heap allocation/free paths. This ensures the reported statistics reflect the current memory footprint of each process. Wire the new query into the GET_ARRAY implementation to expose the usage information to userspace.

accel/amdxdna: Return ERR_PTR on dma_alloc_noncoherent failure

2026-03-23T20:29:22Z

dma_alloc_noncoherent() returns NULL on failure, but callers of aie2_alloc_msg_buffer() check for IS_ERR(). Return ERR_PTR(-ENOMEM) instead of NULL to match the amdxdna_iommu_alloc() path and the caller's error checking convention.

accel/amdxdna: Refactor GEM BO handling and add helper APIs for address retrieval

2026-03-21T05:12:49Z

Refactor amdxdna GEM buffer object (BO) handling to simplify address management and unify BO type semantics. Introduce helper APIs to retrieve commonly used BO addresses: - User virtual address (UVA) - Kernel virtual address (KVA) - Device address (IOVA/PA) These helpers centralize address lookup logic and avoid duplicating BO-specific handling across submission and execution paths. This also improves readability and reduces the risk of inconsistent address handling in future changes. As part of the refactor: - Rename SHMEM BO type to SHARE to better reflect its usage. - Merge CMD BO handling into SHARE, removing special-case logic for command buffers. - Consolidate BO type handling paths to reduce code duplication and simplify maintenance. No functional change is intended. The refactor prepares the driver for future enhancements by providing a cleaner abstraction for BO address management.

accel/amdxdna: Support retrieving hardware context debug information

2026-03-17T21:08:57Z

The firmware implements the GET_APP_HEALTH command to collect debug information for a specific hardware context. When a command times out, the driver issues this command to collect the relevant debug information. User space tools can also retrieve this information through the hardware context query IOCTL.

accel/amdxdna: Allow forcing IOVA-based DMA via module parameter

2026-03-12T19:37:56Z

The amdxdna driver normally performs DMA using userspace virtual address plus PASID. For debugging and validation purposes, add a module parameter, force_iova, to force DMA to go through IOMMU IOVA mapping. When force_iova=1 is set, the driver will allocate and map DMA buffers using IOVA.
