there is early return in prepare.

Dynamic partial update feature enabled post processing OR
partial update based on client preference. In case of framework
reboot, HWC needs to preserve the last set preference of these
features.

Expose binder API to control partial update dynamically. Partial
update feature cannot co-exist with post processing features
dependent on histogram data. With this API, OEM's can set their
preferences on these features on use case basis.

The driver now sends the actual usable mixer stages, so no need to
deduct the STAGE_UNUSED and STAGE_BASE.

Do not disable mdp comp on external based on primary resolution for
quality concerns. The app could still be rendering at a lower
resolution and disabling will cause performance issues in mirroring.
Use the newly added property persist.hwc.maxseclayers to restrict
mdp comp on external for desired devices.

** 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.

Add support for configuring the maximum mdp layers on secondary
via persist.hwc.maxseclayers property. The default value is 1.
Move the check for max allowed layers to postHeuristicsHandling

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.

- Read MDP sys_fs node for blending stages supported per mixer
instead of hard cording the value. This makes the implementation
scalable across chipsets.
- Add binder support to change the max pipes per layer value
dynamically for MDP comp.

For PROTECTED but NON SECURE layers set MDP_SMP_FORCE_ALLOC flag
to allow SMP allocation and prevent GPU fallback
In Such cases if video resolution changes dynamically
it fails to display layer due to GPU fallback.
Use this flag for FB layer composition and depricate
MDP_BACKEND_COMPOSITION flag.

1. Remove AIV video mode composition stratergy and reuse video only
composition stratergy to achieve the same functionality.
2. Drop all non AIV layers from the external list at the start of MDP
composition prepare and fall back to video only composition.

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.

memset dropArray and set dropCount to 0 before proceeding
to identify if refresh rate needs to be changed. Not doing
this will result in dropCount containing junk value which
will impact mdpCount. This prevents us in changing refresh
rate in cases where it could be changed.

Enable partial update for MDP3 targets.

to avoid composition of layers outside ROI.

Add support for dynamically setting idle timeout values.
Move default idle timeout setting to IdleInvalidator.
Fix static var naming, handle errors from IdleInvalidator in hwc.
Property debug.hwc.idletime is removed with this change.
Example:
1) Set idle timeout to 100ms
adb shell service call display.qservice 16 i32 100
16 is the code for SET_IDLE_TIMEOUT, 100 is time in ms
2) Disable idle timeout
adb shell service call display.qservice 16 i32 0

to targets after 8974 v2.

- The primary panels refresh rate can be change by clients
- Required refresh rate will be set by client using metadata
- If there are multiple clients requesting, it will be used only
when the refresh rates are equal, else it resets to default
- Set the new refresh rate only when there are only YUV layers
updating or when the list has only one RGB layer updating
- MdpVersion gets the dyn fps capabilities from panelInfo

1. Add support for Dynamic Resolution Change
We add support for DRC on virtual displays. This is achieved
by reading the width and height attributes that are set as
part of the buffer handle metadata.
For the WFD use cases, the WFD MultiMedia framework will
update the width and height during DRC by using setMetaData
API with UPDATE_BUFFER_GEOMETRY. We then proceed to configure
WB with the new resolution for subsequent frames.
2. Update WB dump with output buffer format and resolution
Update WB dump with output buffer format and resolution. This is
helpful for debugging purposes.

1. Fall back to video only composition instead of full GPU composition
to release all pipes assigned to RGB layers for primary display
during external configuration and padding round. Do this only for
the target which has total number of pipes >= 8.
2. This resolves blinks when HDMI is connected during secure video
playback usecase.
