Subject: [PATCH] drm/i915: Push vblank enable/disable past
|
||||
encoder->enable/disable
|

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).
