If the display list contains single layer and that layer
has same properties as Frame Buffer, avoid BLIT on Frame buffer
and pass it directly to display.

- If virtual display is connected, call blank IOCTL on it as well
- Clear writeback object on blank, as pause/resume functionality
implemented in VDS takes care of sending black frame on suspend.

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.

Use change in HWC_GEOMETRY_CHANGED flag appropriately to avoid

* 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.

Clear overlay and layer-rot map from the top level caller of
composition, rather than from the place of actual intermediate
failure. This makes sure, even in cases of GPU comp failure,
overlay and layer-rot maps are cleared and eventually pipes unset.

There is no need to re-program the H/W, if the frame geometry of all
active displays, has not changed. It will help to improve performance
by avoiding re-configuration of HAL and driver, if it is not needed.

* Set DMA state at the start of the composition cycle
based on the following.
Set it to LINE_MODE if the number of active rotator
sessions are 0.
Set it to BLOCK_MODE if
** A yuv-layer for any display-device requires rotation
** (or) mExtOrientation is set
** (or) mBufferMirrorMode is set
* Separate out the reset helper function into more
modular ones

2. Set the GPU hint to default if the current composition type is GPU

- 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

Do not proceed with panel recovery sequence if panel is already off.
Proceeding with reset sequence, if panel is already off, results in
race conditions.
One e.g., there is race condition between early suspend triggered
by pressing power key and panel recovery triggeredby ESD uevent.
If pressing power key happens exactly at kernel DSI driver is
reporting ESD uevent, it's likely that panel will be unexpectedly
on by ESD uevent after having blanked the screen by early suspend.
This change avoids unintentional panel recovery in the case above.

* 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.

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.

If VDS is connected, do not clear WB object as it will end up
detaching IOMMU. We need to keep the WB session active in order
to send a black frame to WFD sink on power suspend.
For AD use case, we will keep the WB object active.

Vpuclient is the client side for VFM in hwc. It follows the
similar pattern of prepare and draw. It has 2 step prepare
including: setVpuSession and prepare. The setVpuSession function
passes all the layers from the SF list to VFM, which marks
the layers that it can support. After this, the layer
allocation/configuration is done, and finally in prepare the
allocated pipes are passed down to VFM. The draw function
passes the handle to the VFM to draw the video layer.

* 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
step 4: adb shell start

* When a non-WFD virtual display device (SSD/
screenrecord) is active along with
non-hybrid WFD solution(WFD faked on
external), give preference to non-hybrid WFD
device over non-WFD virtual display device.
* This is needed only in cases when WFD is
enabled via v4l2 rather than using VDS api's.

2. Overload the functionalities for VDS and V4L2 WFD solutions.
3. Instantiate VDS object or V4L2 object during hwc init based on the

4. VDS solution is not verified as it requires some dependent changes.
