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.

Default display mode needs to applied exactly on boot
completion. Hence we check for the exact instance of
boot completion by checking the property of boot
animation exit. We keep on checking till the property
is found to be set and program the default mode over
a dynamic link to libmm-qdcm.so

MDP pipe width should be used to find the number of overlay
pipes needed for configuring a hwc layer. Split display should
use the max mixer width supported by the H/W to check against display
resolution to detect split displays.

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.

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.

In the configureSourceSplit() helper (nothing to do with SourceSplit
feature) BWC is being set in all rotator cases.
Remove that since we use that function when layers are forced split,
and we cannot have BWC.

- This also helps in use case where HPD is turned off
(on purpose)through by adb shell for power testing
and on suspend/resume, it gets re-enabled.

** 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.

Due to h/w limitations hwc cannot use bwc when video-mode panels are
active in system. Disable bwc when HDMI intf is active.
For video-mode primary the driver disables the feature via
capabilities node.

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.

When a layer has 90 or 270 degree orientation flag set, the source buffer will be
rotated before MDP scales it up or down, if applicable. So while
checking the layer for scaling for configuration decisions in
HWC, we need to consider its orientation flags.

We are adding support for HDMI as Primary to the display HAL.
The HAL must be able to support boot-up use cases and cable
connect/disconnect events as follows:
1. Boot up with HDMI cable connected
For this scenario we read the best mode supported by the
HDMI TV and set that as the current and default mode for
subsequent boot up.
2. Boot up without HDMI cable connected
We read a default resolution from the driver by reading vscreen
and reporting this as the display resolution to SF.
3. Switch the display to active state when we receive first frame
When HDMI is primary we should rely on the first valid
draw call in order to activate the display
4. Update handling of uevents when HDMI is primary
a) Do not send hot plug when the cable is connected/disconnected.
b) Use the correct display ID in uevents when HDMI is primary
5. Handle display timeout when HDMI is Primary
When HDMI is connected as primary we clean up resources
and call commit to generate a black frame on the interface.
However, we do not call blank since we need the timing
generator and HDMI core to remain turned on.
6. Clear pipe resource when HDMI is disconnected
When HDMI is primary, we need to make sure that SF/HWC does
not have any open fd's when the cable is disconnected.
We clear all pipe resources and call a display commit to ensure
that all the fd's are closed. This will ensure that the HDMI
core turns off and that we receive an event the next time the
cable is connected.

1. This feature is targeted to remove any window/pillar boxing on
external display when zoom mode is enabled.
2. Preserve the aspect ratio of the external display by cropping and
upscaling the tagged video layer during video playback on external.
3. User can tag the layers to be displayed on external display.
4. Set sys.hwc.windowbox_feature to true to enable this feature
Assumptions & Limitation:
1. Tagged layers for external display will also be displayed on
primary display along with untagged layers
2. When zoom in mode is enabled, source crop left and source crop
top of a tagged video layer is always assumed to be set to
positive integer value. So pinch zoom feature or zooming in top
left corner of the video use case cannot be supported.
3. Except tagged video layers, all other tagged UI layers will
use GPU for composition on external display, So all tagged UI
layers cannot be secure layer.
4. Rotation animation cannot be supported for this feature.
