Copy bit in mdp3 uses frame buffers as destination surface,
hence no need to pass release fence to copy bit.

- 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.

- All secure layers are marked with GRALLOC_USAGE_PROTECTED,
irrespective of L1/L3, which should not fallback to GPU.
- In HWC, treat this layer as secure so that any fallbacks
will be avoided.

- 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.

* Until now it's been the case that refresh-rates were set to
the standard values of 24, 30, 48 and 60 for video playback
usecases. Since of the most panel vendors can only support
refresh-rates above 45, in many of the use-cases with fps < 45,
dynamic change in panel refresh rate doesn't happen.
* To address this, following are the changes done:
1. Refresh-rate will no longer be limited to standard values
for video-playback usecases and any value above the
minfpsSupported which is advertised by the mdss driver will
be considered.
2. If the fps of the use-case is 'x' and it falls less than
minfpsSupported, a multiple of it 'k*x' will be considered as
the new refresh-rate, provided k*x < 60. If
abs(k*x - stdRefreshRate) < 2, set the refresh-rate to the
standard value rather than k*x.
* With the above two optimizations in place, if the panel has
a minfpsSupported value of 45, and if the use-case fps is 12,
the new refresh-rate would be set as 12 * 4(= 48) instead of 60
which had been the case.
* The above two optimizations will result in dynamic change in
refresh-rate happening more often, in local video and streaming
use-cases and will help in improving DOU(Days Of Use) metric.

- 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

1. Add one binder command to display.qservice to serve the
binder requests received from SDK.
2. Each subcommand will be corresponding to one command
handler. Command handler will pass the requests to
qdcm library.
3. Dynamically load qdcm library, where all apis are
implemented.
4. apply default mode function will be invoked once
bootanimation event is detected

Property "service.bootanim.exit" was read before applying Default
Mode. This property is set in SurfaceFlinger when boot finish is
triggered which is happening before Bootanimation is completed
which results into some of the Bootanimation frames with default
mode settings.
Replace this property with "init.svc.bootanim" which is checked to
be "stopped" before applying default mode. This results into first
frame of homescreen to be with default mode settings.

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

Add support for panel resolution switch. This feature makes use of
the Linux modedb feature that lists available modes in
/sys/class/graphics/fb0/modes and accepts a mode change when written
to /sys/class/graphics/fb0/mode
Clients can link to APIs exposed in display_config.h, these
internally resolve to binder calls into HWC. For debugging, mode
changes can be made over binder using shell commands.
adb shell service call display.qservice CODE ARGS
ARGS can include config index and display (only primary supported)
setActiveConfig():
adb shell service call display.qservice 25 i32 INDEX i32 0

- When fb open fails during hwc initialization, it should be
flagged as a fatal error and HAL should return error.
- Without this, the SF would make calls to HWC that would fail,
and display being blank.

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.

Remove that since we use that function when layers are forced split,
and we cannot have BWC.
