drm/imx: handle pending updates better, add plane zpos property support

- Add a mechanism to only send commit done events once all pending
  updates have been applied. This closes a small race window where
  already armed events could fire even though the double buffered

- Add plane zpos property support to allow placing the overlay plane

to the frame end, so the hardware will only apply the current state on the

has been applied successfully.

drm/amd/display: Do cursor updates after stream updates

[Why]
Cursor updates used to happen after vblank/flip/stream updates before
the stream update refactor. They now happen before stream updates
which means that they're not going to be synced with fb changes
and that they're going to programmed for pipes that we're disabling
within the same commit.

[How]
Move them after stream updates.

5 years agodrm/amd/display: Fix update type mismatches in atomic check

drm/amd/display: Fix update type mismatches in atomic check

[Why]
Whenever a stream or plane is added or removed from the context the
pointer will change from old to new. We set lock and validation
needed in these cases. But not all of these cases match update_type
from dm_determine_update_type_for_commit - an example being overlay
plane updates.

There are warnings for a few of these cases that should be fixed.

[How]
We can closer align to DC (and lock_and_validation_needed) by
comparing stream and plane pointers.

Since the old stream/old plane state is never freed until sometime
after the commit tail work finishes we are guaranteed to never get
back the same block of memory when we remove and create a stream or
plane state in the same commit.

5 years agodrm/amd/display: Fix wrong z-order when updating overlay planes
Nicholas Kazlauskas [Fri, 18 Jan 2019 18:17:55 +0000 (13:17 -0500)]
drm/amd/display: Fix wrong z-order when updating overlay planes

[Why]
If a commit updates an overlay plane via the legacy plane IOCTL
then the only plane in the state will be the overlay plane.

Overlay planes need to be added first to the DC context, but in the
scenario above the plane will be added last. This will result in wrong
z-order during rendering.

[How]
If any non-cursor plane has been updated then the rest of the
non-cursor planes should be added to the CRTC state.

The cursor plane doesn't need to be included for stream updates and
locking it will cause performance issues. It should be ignored.

DC requires that the surface count passed during stream updates
be the number of surfaces currently on the stream to enable fast
updates. This previously wasn't the case without this patch, so this
also allows this optimization to occur.

drm/amd/display: Ungate stream before programming registers

[Why]
Certain tests fail after a fresh reboot. This is caused by writing to
registers prior to ungating the stream we're trying to program.

[How]
Make sure the stream is ungated before writing to its registers.
This also enables power-gating plane resources before init_hw
initializes them.
Additionally, this does some refactoring to move gating/ungating
from enable/disable_plane functions to where stream resources are
