linux-toradex.git/Documentation/accel/amdxdna, branch master Linux kernel for Apalis and Colibri modules accel/amdxdna: Expose per-client BO memory usage via fdinfo 2026-04-09T20:41:47+00:00 Lizhi Hou lizhi.hou@amd.com 2026-04-09T15:22:59+00:00 e0169d0c690f03f379bf71d9332bb2065a5c6a05 Implement amdxdna_show_fdinfo() to report per-client memory usage, including below driver-specific memory stat: - heap allocation - internal BO allocation - external BO allocation Hook the implementation into the DRM fdinfo infrastructure via drm_driver.show_fdinfo, while continuing to expose standard DRM memory stat through drm_show_memory_stats(). This improves observability of per-process memory usage and aligns with existing fdinfo reporting mechanisms used by other drivers.

Implement amdxdna_show_fdinfo() to report per-client memory usage,
including below driver-specific memory stat:
  - heap allocation
  - internal BO allocation
  - external BO allocation

Hook the implementation into the DRM fdinfo infrastructure via
drm_driver.show_fdinfo, while continuing to expose standard DRM
memory stat through drm_show_memory_stats().

This improves observability of per-process memory usage and aligns
with existing fdinfo reporting mechanisms used by other drivers.
