-Subject: [PATCH] drm/i915: Push vblank enable/disable past
- encoder->enable/disable
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-It is platform/output depenedent when exactly the pipe will start
-running. Sometimes we just need the (cpu) pipe enabled, in other cases
-the pch transcoder is enough and in yet other cases the (DP) port is
-sending the frame start signal.
-
-In a perfect world we'd put the drm_crtc_vblank_on call exactly where
-the pipe starts running, but due to cloning and similar things this
-will get messy. And the current approach of picking the most
-conservative place for all combinations also doesn't work since that
-results in legit vblank waits (in encoder->enable hooks, e.g. the 2
-vblank waits for sdvo) failing.
-
-Completely going back to the old world before

-    drm/i915: Use generic vblank wait
-
-isn't great either since screaming when the vblank wait work because
-the pipe is off is kinda nice.
-
-Pick a compromise and move the drm_crtc_vblank_on right before the
-encoder->enable call. This is a lie on some outputs/platforms, but
-after the ->enable callback the pipe is guaranteed to run everywhere.
-So not that bad really. Suggested by Ville.
-
-v2: Same treatment for drm_crtc_vblank_off and encoder->disable: I've
-missed the ibx pipe B select w/a, which also has a vblank wait in the
-disable function (while the pipe is obviously still running).
