[v2,0/3] Support fdinfo runtime and memory stats on Panthor

Message

Adrián Larumbe April 23, 2024, 9:32 p.m. UTC

This patch series enables userspace utilities like gputop and nvtop to
query a render context's fdinfo file and figure out rates of engine
and memory utilisation.

Changelog:
v2:
 - Split original first patch in two, one for FW CS cycle and timestamp
 calculations and job accounting memory management, and a second one
 that enables fdinfo.
 - Moved NUM_INSTRS_PER_SLOT to the file prelude
 - Removed nelem variable from the group's struct definition.
 - Precompute size of group's syncobj BO to avoid code duplication.
 - Some minor nits.

Adrián Larumbe (3):
  drm/panthor: introduce job cycle and timestamp accounting
  drm/panthor: Add DRM fdinfo support
  drm/panthor: Enable fdinfo for memory stats
