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

Added a new layer flag: HWC_VPU_PIPE to indicate that the layer
will be drawn by VPU. There is a corresponding MDP pipe
flag: MDP_VPU_PIPE, which should be set for the VPU layers to
indicate the layer will be drawn by VPU, so that MDP driver does
the appropriate settings to allow this process.

* 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.

Type casting to float prevents rounding off errors which could
result in invalid or unexpected results when doing calculations
with integers.

1. Define classes for VDS and V4L2 based WFD solutions.
2. Overload the functionalities for VDS and V4L2 WFD solutions.
3. Instantiate VDS object or V4L2 object during hwc init based on the
property persist.hwc.enable_vds set by the user.
4. VDS solution is not verified as it requires some dependent changes.

Macro tile is enabled only if all the conditions are met:
1. GPU hardware should support Macro Tiling.
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.
5. persist.hwc.macro_tile_enable flag should be enabled.
PRIV_FLAGS_TILE_RENDERED flag is added to indicate whether the layer
is rendered/composited in Macro Tiling or Linear format.

- Its used only in case of MDP copybit

Earlier, on configuration errors, we simply drained the fences held
by current rotator objects and went to GPU comp. The rotator objects
were deleted in the subsequent rounds, if they remained unused.
If we don't use GPU comp on failure but use other strategies, then we
need to mark the rotator objects for a display for reuse, so that
other strategies can use them.
Also any failure resets on overlay or rotator need to happen from
functions that call configuration helpers rather than the helper
themselves. Leaving cleanup to black-box helpers is not desirable.

Add hw limitation checks for MDP composition once
we identify actual layers for MDP. This should be generic
way for all basic hw limitations of underlying MDP/MDSS.
Current limitations:
- a-family : MDP can not handle alpha scaling.
- 8226 & 8974 : Can not handle if multiple layers need
downscaling and blending

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.

To minimize usage of decimation when 4K x 2K video is played
on primary, split the yuv layer into 2 halves and configure
each layer to individual VG pipes. With this approach,
decimation can be avoided in some 4K x 2K video use cases,
thereby improving performance.

1. Color layer has a destination rectangle, RGBA color and plane
alpha. There is no gralloc buffer. Layer flag "HWC_COLOR_FILL"
denotes a Color layer.
2. There is no color member in HWC layer, so RGBA color value
is passed via the "tranform" member from framework to HAL.
