- Populate frame_rate in rotator set, so that driver
can vote for honest BW for rotator based on frame rate.
- If metadata contains source fps, frame_rate will be set
to source fps, else it will be set to primary refresh rate.
- frame_rate will be populated for primary with
source fps from metada, only when secondary is not active.

- In targets with fewer pipes, composition switch can happen
continuously for a layer based on whether it is updating or not.
If that updating layer requires downscaling, because of the
difference in the downscale filters between MDP and GPU,
the output of MDP and GPU will differ. This difference could be
perceived as flicker. To avoid this flicker, mark RGB downscaled layer
with downscale more than threshold to GPU always.
- property persist.hwc.downscale_threshold defines the threshold value
for downscale beyond which the layer will be marked for GPU composition.

When external is active and primary has all ViG pipes, a video
playback may be starved of pipes on external. Use one GPU comp.
round for high-end targets as well.

* On Low end targets which has constraint on the #pipes, avoid
fullMDPComp and fullMDPCompWithPTOR on primary
when secondary is connected and secondary has a YUV layer.
* This helps in secondary have sufficient number of RGB or DMA pipes
to handle sudden increase in #layers.

- Retrieve cursor pipe info from driver
- Configure the layer marked with flag HWC_IS_CURSOR_LAYER to the
HWCursor using the fb_cursor ioctl.
- The config happens only when it satisfies the hw limitions of
cursor
- HWCursor is supported on primary display
- Since cursor configuration happens first, make use of drop
layer/count to handle other composition strategies
- Add support for hwc_setCursorPositionAsync as per HWC 1.4

There could be scenarios where the bottom layers are RGB, which could
take up all ViG pipes as well, leaving no pipes for videos. Using
mixed mode may not help if those RGB layers are updating, since GPU
will be continuously invoked.
This patch reserves pipes for videos instead of serial order.

* Until now, it was the assumption that when display animation
is in progress and there is a video rotation involved, the yuv-layer
would be marked as skip till completion of display animation.
But this is not always the case.
* On low-end targets, there is a constraint on #VG-pipes and
during video playback, video on primary is composed using GPU
where as video on secondary is composed using MDP. When display
animation is in progress, in such usecase, ensure that MDP is
is completely avoided so that VG pipe is available to secondary
once display animation is done.
* On high-end targets, video on both primary and secondary are
composed using MDP due to sufficient VG pipes. When display
animation is in progress, in such usecase, ensure to skip
fullMDP and partialMDP composition strategies so that
VG pipe that was supposed to be available for secondary is not
used for RGB layers on primary.

* When the ambient light changes, pp-daemon will invoke multiple
screen-refresh cycles for LUT convergence needed for
PP algorithms.
* When this happens during static screen usecase, there would
be frequent switches from gpu-comp(due to idlescreen-fallback)
to mdpcomp and back. This results in increase in power numbers
due to increased composition cycles.
* To resolve this, do the following:
a) If frame 'n' is composed using GPU and frame 'n+1' is same
as frame 'n' in terms of input layers contents, avoid any
composition needed for frame 'n+1'. Mark the composition type
for all the layers as HWC_OVERLAY and push the GPU composed
content of frame 'n' for 'n+1' too.
b) Donot do (a) if the any of the incoming layers is marked as
skip or HWC_GEOMETRY_CHANGED flag is set in layer list.
c) Limit (a) to only primary and when secondary is not connected
so that display output expectations during secondary pause-resume
can be met.
* This saves ~10ma during static screen usecase when ambient
light is frequently changing.

When client prefer to enable PU(partial update) over PP(post
processing), delay enabling PU until PP turns off its
features completely. This change introduces hand shaking flags
between PP and HWC through binder calls. When requested to turn
on PU, we notify PP through the sys_fs node. When PP is done
shutting off it features, it acknowledges back to HWC to actually
turn on PU.

split.
1) When source split is enabled, both the panels are calibrated
in a single coordinate system. So only one ROI is generated
for the whole panel extending equally from the midpoint and
populated for the left side.
2) Fixes a bug in mdpcomp where ROI generated for the frame is
reset when a strategy fails.

ping-pong split needs source split to be enabled to stage two
pipes of a layer in the same Z order. This change adds partial
update support to generate ROI when source split is enabled.
When configured, ping-pong-split splits the layer mixer output equally
across two DSI's. To meet this limitation, the generated ROI is
adjusted to have equal widths from the panel mid point.

With source split enabled:
1) When both LEFT and RIGHT pipes gets reused pipes, we use their
pipe id's to compare their priority and swap them as needed.
2) When both LEFT and RIGHT pipes needs to be newly allocated, we
let driver take care of the priority as long as both pipes are
of same type. If different, we swap them according to the pipe
type priority.
3) When LEFT is reused and RIGHT needs new allocation, we swap
them only when they need same pipe type and LEFT has the
pipe with lowest priority.
4) When RIGHT is reused and LEFT needs new allocation, we swap
them only when they need same pipe type and RIGHT has the
pipe with highest priority.

1. Add support for UBWC allocation in the Gralloc APIs for aligned
width, aligned height and buffer size. A client can request for UBWC
allocation by sending UBWC specific HAL pixel format or by setting
GRALLOC_USAGE_PRIVATE_ALLOC_UBWC flag in the usage flags.
2. Gralloc allocates UBWC aligned buffer, only if format is supported
by GPU and MDP and no CPU usage flags are set. Otherwise it allocates
linear buffer.
3. If UBWC conditions are met, gralloc sets PRIV_FLAGS_UBWC_ALIGNED
in private handle flags to tell client that allocated buffer has UBWC
alignment. This flag remains unset by default.
4. Add helper functions in gralloc to calculate UBWC meta buffer size
for RGB* formats.
5. Add UBWC HAL pixel format HAL_PIXEL_FORMAT_YCbCr_420_SP_VENUS_UBWC
which has been defined by Video module.
6. Add AdrenoMemInfo api to query, if GPU supports UBWC for a format.
7.MDP driver expects UBWC specific pixel format defined by MDP header.

MDPOnly composition needs to cater for the use case when we have
secure RGB layers that require MDP composition. For non-secure RGB
layers we can afford to send them for GPU composition. This is
especially needed for the following use case: full MDP composition
on primary (including YUV layers), followed by external connection.
For the mentioned use case, we need to fall back to Video and then
GPU composition in in order to reclaim pipe resources for external
usage.
