Subject: [PATCH v2] drm/panthor: register size of internal objects through fdinfo
This includes both DRM objects created to support queues, groups and heaps,
and also objects whose pages are shared between the GPU and the MCU.
However, this doesn't include objects that hold the firmware's binary
regions, since these aren't owned by a render context and are allocated
only once at driver's initialisation time.
This will display four key:value pairs which exist beyond the drm fdinfo
standard, and that record the sizes of internal objects:
drm-total-internal, drm-shared-internal, drm-active-internal and
drm-resident-internal.
Currently, drm-shared-internal and drm-active-internal are unutilised, but
in a future revision of the patch 'drm-shared-internal' could register the
size of the firmware regions (since they aren't specific to a single render
context), and 'drm-active-internal' could be updated every time a group is
made active by the GPU scheduler or a queue has jobs ready for execution.
Signed-off-by: Adrián Larumbe <adrian.larumbe@...labora.com>
