DirtyRect for a layer is generated w.r.t to its buffer
coordinates. It needs to be mapped for layer destination
(display) coordinates before using it to calculate the frame's
ROI.

For panels that cannot accept commands in both the interfaces, we cannot
send two ROI's (for each half). We merge them into single ROI and split
them across lSplit for MDP mixer use. The ROI's will be merged again
finally before updating the panel in the driver.
- Reads panel property of dual control path.
- If dual control path not supported, merge ROI's before
analysing for composition strategies.

Extends partial frame update support for split displays by calculating
changing region(ROI) independently for each half of the screen. In case of
only one half updating, display driver shuts down the DSI/MDP mixer control
of the non updating half.
Maintains two ROI's for each display. In case of Non-split
displays, only left ROI is updated.

When validateAndSet fails we must reset the mDoable flag to false and
close the fb device. This will prevent making a draw call using
invalid resource references and prevent any fd leaks.
Additionally, we should only turn AD on if there are no configuration
errors during prepare call. This will prevent toggling AD between
on/off state in the face of continuous failures.

Since both has same number of pipes with similar
features like scaling capabilities, for now rely on 8x16.

Enable source split for targets with single dsi. This has the
benefit of using 2 pipes for layers whose width (crop) is higher
than line width.

* Mdss driver supports DMA-Multiplexing on wb interface
for certain targets. Add overlay get function to query
this info during pipe allocation for wb.
* UI Scaling on external is not supported on certain
targets due to the lack of availability of pipes with
scalars. Add overlay get function to query this info
to disable action-safe calcs, DRC and others which
require downscaling.

For 8x26, if external display is connected, DMA pipe should never
be occupied by primary display. Otherwise, external display would
lack DMA pipe if switch to GPU composition.

Rely on panel info shared by driver and enable
partial update if it says as supported. Use the
existing property to disable partial update if
required for debugging.

No need to draw dropped layers while doing video only composition
since they are lying outside updating ROI.

Add support for returning pipes based on capabilities.
getPipe() API takes in pipe specifications like format class,
scaling, display, mixer, fb and decides what pipe to return.
The nextPipe() API is now just a private helper.

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.

Increment fbZ when 4k2kyuvindex matches with fbZ,
otherwise we see momentary flicker as right half of
4k2k YUV layer and fb layer have same z-order.

Add rotator obj to the layer-rot-map soon after its successfully
acquired. This makes sure that any object allocated is accounted
for, irrespective of whether rotator configuration succeeds or not.

Color layer always has zero transform because framework uses the
transform member of hwc layer to pass the color value to HAL.

- Add utility function for 8x16
- Add internal function to identify if RGB doesn't
support scaling that is read from capabilities node.
- If UI layer needs scaling and RGB pipe doesn't
support scalar, request a VG pipe
- On 8x16, request DMA pipe for WFD

When layer format is macro-tile, decimation cannot be supported.
Add necessary checks to bail out for such use-case.
Change-Id: I711f07a2963a76280a08887d04770cd418d8bd1e
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.

While performing load based mixed composition, iterate from max
stages of mixer to at least 2.
Get rid of modes that preferred GPU or MDP. This new mode will
include both plus the missed out batches.
Change-Id: Ideb06a2332fe2f59968367d28df848be01f4aedc
Bandwidth checks will be done in the driver as part of resource check
which makes the existing checks in hwc redundant.

While doing mixed mode composition, update only the region of the
framebuffer where layer contents are cached or updated. Avoids
MDP fetch for non-visible contents of FB.

1. Use kernel timer interrupt to signal about the timeout to
Invalidator thread and fallback to GPU composition.
2. This implementation avoids waking up the Invalidator thread for
every idletimeout value during continuous update.
Change-Id: I4370f10a0ca06b5cb1e7bdcb047e9c8daec51afb
Pipe estimation was necessary when the unavailability from overlay
led to GPU fallback.
With the new design, hwc uses the next best strategy, so failure
to grab a pipe from overlay is ok.

* In some use-cases, it is possible that there are
no AppBuffer layers on the external/virtual layer-list
during which all the pipes will be allocated to the
primary. When layers do comeup on external/virtual
layer-list, subsequent overlay sets fail.
* This change ensures that in such cases, we invoke a
padding round on all the displays to free up the
hw resources which can be used in subsequent cycles.

In Video-only mode FB Z-order of 0 was being used, incorrectly,
because the value was reset to 0 and wasn't changed subsequently.
Reset to -1 to prevent this. Any MDP comp strategy that needs to use
FB should set it's Z order appropriately.
If cache based mode has no MDP comp layers, fail so that other
strategies can be used, rather than succeeding with FB Z as 0, which
will at most allow GPU comp to be used.
