MLK-18873: drm: imx: dcss: request PM QoS only when VBLANK is on

DCSS needs PM QoS in order to keep interrupt latency low. Otherwise,
page flipping will not work smooth enough because CTXLD will not be
triggered in time.

Currently, PM QoS is requested all the time but that does not allow the
CPUs to go idle. Hence, this leads to increased power consumption.

This patch will change how PM QoS is requested by doing it only when
VBLANK is enabled/disabled. The VBLANK interrupt is enabled just before
a commit takes place and disabled after one second after last commit.
This will allow DCSS to function properly and, also, allow CPUs to go
idle whenever there's no buffer submitted.

Exception to this is when DTRC is used (when DCSS is passed tiled
buffers). In this case, PM QoS will always be active, even if no buffer
is submitted, because DTRC banks need to be switched in CTXLD ISR, so
that DCSS does not underrun. DTRC does not have the REPEAT feature, as

Currently, there's a hardcoded wait time (500ms) after enabling DTG

However, this time is quite big. This patch changes this by lowering this

f9a03b3 - MLK-17925: drm: imx: dcss: fix tearing

introduced a regression because we does not send VBLANK event if context

after enabling the CRTC. Hence, when 30FPS modes are selected, it is
possible to exceed the 50ms vblank timeout if the first event is not

modes though.

MLK-17925: drm: imx: dcss: fix tearing

That's because, sometimes, the context loader could be armed after the
DB event came in the frame trace. That made a buffer submitted in frame
N end up on screen in frame N+2 because the context loader waits for the
next DB event. Since vblank events are sent at the end of the frame, by
the time the buffer lands on screen, the application will reuse it while
it's being displayed, hence the tearing effect.

This patch moves the CTXLD trigger moment all the way to the end of the
frame trace, just before DB event arrives. This will leave the
application plenty of time to submit new buffers.

In the event that the trigger moment is missed (application submits a
buffer right at the end of a frame trace), then we're not signalling the

the buffer is still needed and will not submit a new one.
