[PATCH v5 0/4] drm/amdgpu: Wire GPU events into EVENTFD notifications

This series wires GPU events into the render-node EVENTFD
notification infrastructure.

It builds on the render-node EVENTFD infrastructure by adding
notification producers for USERQ_EOP, QUEUE_RESET, and GPU_RESET
events.

QUEUE_RESET notifications are generated from the common
queue-specific reset helper, while device-level reset accounting
and DRM wedged-event notification remain in the top-level
recovery paths.

Patches
=======

  1. drm/amdgpu: Signal USERQ_EOP EVENTFD notifications
  2. drm/amdgpu/userq: properly account for resets with user queues
  3. drm/amdgpu: Signal QUEUE_RESET EVENTFD notifications
  4. drm/amdgpu: Signal GPU_RESET EVENTFD notifications

Changes since v4
================

- Rebased on the latest user queue reset handling changes.
- Reworked the QUEUE_RESET producer to reuse the common
  queue-specific reset helper.
- Kept device-level reset accounting and DRM wedged-event
  notification in the top-level recovery paths.

Only compilation tested.
