[PATCH v2 0/5] drm/vblank: Deferred Enable and Disable

[<sunpeng.li@amd.com>]

From: Leo Li <sunpeng.li@amd.com>

See cover letter from v1 for motivation and details:
https://lore.kernel.org/dri-devel/20260224212639.390768-1-sunpeng.li@amd.com/

v2 contains fixes to some failing igt@kms_vblank tests, namely
* any test that calls wait_for_vblank()
* ts_continuation_dpms/modeset tests

Fixes are all in patch 2/5, the other patches remain unchanged.

Leo Li (5):
  drm/vblank: Add drm_crtc_vblank_is_off() helper
  drm/vblank: Introduce deferred vblank enable/disable
  drm/amd/display: Refactor amdgpu_dm_crtc_set_vblank
  drm/amd/display: Implement deferred vblanks on IPS platforms
  drm/vblank: Add some debugging trace events
