- Instead of assuming the default format(RGBA_8888),
read FB format from driver and pass the info to SF
- For now, this is limited to primary and HDMI only.
WB FBformat is assumed to be in RGBA_8888
- If FB doesn't have alpha channel, disable mixed mode

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.

* Explore cachebased and loadbased composition strategies
eventhough skip layer is present in the layer list.
* Prioritize loadBasedComp over cacheBasedComp in such case.
* Invoke redraw of FB for every-frame as long as skip-layer

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.

- Set the perf hint when there is only one updating layer, which helps
in reducing cpu params and thus reduce power.
- This feature is enabled with the property persist.mdpcomp_perfhint,
which is set to a positive value, which will be the window of frames
before the perf hint is set

Not necessarily the max width supported by the MDP pipe and mixer
need to be same. HWC has to make the decision for using one OR
two pipes per layer only based on the max width supported by the
pipe not the mixer.

Do not disable mdp comp on external based on primary resolution for

resolution and disabling will cause performance issues in mirroring.
Use the newly added property persist.hwc.maxseclayers to restrict

** Now, there are two ways for the clients to request
change in the refresh-rate of the target.
(a) Using metadata of the input-buffer.
(b) Using binder api added as part of this change.
** configureDynRefreshRate binder api provides three
op-modes which can be used as following:
(a) "DISABLE_METADATA_DYN_REFRESH_RATE" can be used by the
clients, to disallow display-hal from honoring refresh-rate
change requests, made by video-clients using the metadata.
For ex: This can be used during streaming use-cases
(Dash-playback, playback at WFD-sink,etc) where the idea
is not to change the refresh-rate, though video-client
requests for it using metadata, as video-clients cannot
distinguish between streaming and non-streaming usecases.
Usage:
adb shell service call display.qservice 18 i32 0 i32 0
(b) "ENABLE_METADATA_DYN_REFRESH_RATE" can be used by the
clients after DISABLE_METADATA_DYN_REFRESH_RATE, to once
again allow display-hal to be able to change refresh-rate
based on requests made by the video-clients using metadata.
For ex: This can be used by clients( Dash-playback,
WFD, etc) once they are done with their use-case.
WFD-framework will also use this when the wfd-session is
paused.
Usage:
adb shell service call display.qservice 18 i32 1 i32 0
(c) "SET_BINDER_DYN_REFRESH_RATE" can be used by the clients
to change the refresh-rate of the target using binder-api,
provided they have disallowed display from honoring the
refresh-rate requests made using metadata.
In other words, changing refresh-rate through this binder
api and using metadata approach cannot co-exist together.
Usage:
adb shell service call display.qservice 18 i32 2 i32 45
-- The refresh-rate set here will correspond to 45fps.
** Added property "persist.metadata_dynfps.disable" that
can be used by OEM's, to disable setting of refresh-rate
using the metadata.

The layer clock is dependent on vertical downscaling and horizontal
dest width (pixels). When comparing to mixer's requirements,
line-time can be ignored since it is common to both pipe and mixer.
Also since mixer's scale is 1, layer's downscale * dest width needs
to be compared to mixer's width.

Remove support for toggling BWC via property and add support to
toggle BWC over binder. This will take effect only on targets where
the driver enables BWC.
Example to disable BWC:
adb shell service call display.qservice 17 i32 0
Where 17 is the code to toggle BWC, 0 to disable.
