If using source split to stage 2 pipes on the same mixer stage,
the left pipe needs to be a higher priority than the right.
Add API in overlay to compare pipe priorities and use this in
source split config to stage pipes accordingly.
Add support for 1 pipe config for FB if updating rect is within 2048
pixels.

- Add utility function for 8x16
- Add internal function to identify if RGB doesn't

For dual DSI panels, when enabled partial update AND framebuffer rect
optimization, it is not necessary to update both the halves of
the framebuffer every frame. This channge adds support to update
framebuffer based on the updating region generated.

Add support for SourceSplit. The mixers are abstracted from hwc.
There would be no translations to mixer understood destinations.
1) If a layer's crop and position are < 2048, only 1 pipe can be used
irrespective of position.
2) Else 2 pipes can be used with the layer equally split, without
regard to position.

Send the entire frame (array of overlays) to driver, so that it would
check pipes params and the whole frame wrt bandwidth and SMP.
Now, the overlay's commit API just prepares an overlay object but
makes no ioctl calls.
If the driver finds the frame, as a whole, to be not ok, the
validation fails and overlay/hwc return silently.
If a certain overlay object is mis-configured or pipes are
unavailable, the driver sets the number of objects it processed.
Overlay uses this to dump the incorrect config.

* Useful to estimate GPU/MDP performance for different resolutions.
* MDP:
Every layer is downscaled/upscaled to primary panel resolution.
* GPU:
All layers will be composed in required resolution to FB.
FB is downscaled/upscaled to primary panel resolution.
* Steps to follow:
step 1: adb root
step 2: adb shell setprop debug.hwc.fbsize XRESxYRES
step 3: adb shell stop

2. MDSS hardware should support Macro Tiling.
3. USAGE flags shouldnt contain GRALLOC_USAGE_SW_READ_OFTEN and
GRALLOC_USAGE_SW_WRITE_OFTEN.
4. RGB 16bit and 32bit formats.

PRIV_FLAGS_TILE_RENDERED flag is added to indicate whether the layer

When a rotator or mdp configuration for a display fails, reset the
layer-to-rotator mappings for that display and reset the release
fences for the rotator objects used for that display.
Note: The rotator itself is offline and not tied to any mixer. It is
from the mappings that we deduce which rotator object was used for
layers of which display. Also we don't delete rotator objects held
for a specific display, since during stability runs, failures could
repeat each round and we end up allocating and deallocating memory
unnecessarily. The rotator objects will be deleted automatically
when not required anymore.

A display could be split if its dimensions exceed 2048 or in case
of primary if we make it so via device tree property.
Add an API to find if a display is split. Use this API instead of
going through a set of conditions in various use cases.
Rename the HighRes, LowRes objects to a more appropriate Split and
NonSplit respectively

On WFD/HDMI connection, if the configured resolution is less than
Primary Resolution, Display HAL does the following:
1. sends hpd notification to SF with primary resolution.
2. configures MDP pipes with configured Resolution.
This is done to improve UI quality as MDP has better downscale
filter options compared to GPU.

If the left split is not published by the driver then the default should
be even split. This was missing from the configuration in utils. This is

For split displays, earlier we allowed pipes to switch mixers in
subsequent rounds. This change prevents that and makes sure there

mixer of the same display is UNSET
