1.Select the smaller downscaling ratio for both sides as
rotator needs do the same downscaling for both direction.
2. Use rotator to do the minimum downscaling first to get the
best quality. Use decimation when rotator downscaling is
not enough.
3. Assign z_order when doing resource configuration.
4. For non src split case, if two pipes are on one mixer,
need make sure right pipe has the different z_order.

1. Set the power mode for virtual display while setting power mode for
primary, as surfaceflinger does not invoke SetPowerMode() for
virtual display.
2. Invoke null commit on each display to release all the pipes connected
to it on SetPowerMode().

1. Align rectangle to be even for video format input.
2. Align width and height for rotator downscaling case.
3. Validate scaling again after config is done because scaling ratio
might be changed.
4. Make sure layer count doesn't exceed mixer stage number.
5. Add sde.disable_rotator_downscaling property for disabling
rotator downscaling.
6. Add sde.disable_decimation property for disabling decimation
7. Disable 2 pipes on non-display_split case temporarily as z-order
needs be different

1. Configure the rotator control parameters on every rotator commit
to avoid concurrency issues with HDMI/virtual displays.
2. Pass the layer transform flag properly to SetOutputFormat() to
determine the rotator output format.

1. Compose the first animating frame using GPU on external display.
2. Set composition type of subsequent animating frames as SDE
composition and update cached framebuffer to external display.
3. Close the releasefence fd of framebuffer target during animation.

1. When non-primary displays are registered, set composition mode to
safe mode until resources for the added display is configured
properly.
2. Fix HDMI mirroring issue on framework reboot.
It could be possible that HPD is on during framework reboot.
HDMI driver needs HPD toggling to send uevent to userspace.
Disable HPD at start if HDMI is external, it will be enabled later
when the primary display powers on.

1. Add support to dump the input layers for all displays or each
display separately.
2. Add support to dump output layer for virtual display.
3. Add binder support to enable dump on each display, to enable dump
for input/output layers, and to set number of frames to be dumped.
Syntax:
adb shell "service call display.qservice 21 i32 <FRAME_COUNT> i32
<DISPLAY_TYPE> i32 <LAYER_TYPE>"
FRAME_COUNT = Number of frames to be dumped.
DISPLAY_TYPE = 1 -> To enable dump on primary display
2 -> To enable dump on hdmi display
4 -> To enable dump on virtual display
LAYER_TYPE = 1 -> To enable input layer dump
2 -> To enable output layer dump
To dump 2 frames of input and output layers on virtual display:
adb shell "service call display.qservice 21 i32 2 i32 4 i32 3"

1. Lock prepare() and set() APIs using sequence entry and sequence
exit lock respectively to prevent the critical section being
accessed by other threads.
2. Wait for sequence wait lock on HotPlugEvent thread or any other
binder threads(Eg. dumpsys), before it accesses the critical region.
3. Prevent deadlock during multiple prepare() calls before a set().

1. Create virtual display, if the current virtual display list is
valid and the output buffer handle is not NULL.
2. Configure input and output layers of writeback for the composition
using writeback.
3. Propagate the retire fence back to framework, so that the consumer
will wait for retire fence before it consumes the output buffer.
4. Recreate the virtual display, if the width, height or format of the
output buffer changes.
5. Destroy virtual display, if the current virtual display list is
invalid or the output buffer handle is NULL.

1. Implement Buffer manager to allocate and deallocate output buffers
for rotator.
2. Assign buffer slot for each layer requires rotation and manage the
internal state of buffer slot in buffer manager.
3. Get the output buffer for each layer requires rotation from buffer
manager and associate the information along with that layer.
4. Create/Destroy the rotator session from the hint provided by buffer
manager. This is required to help driver to calculate the bandwidth
for the current frame.
5. Validate the rotator configurations and submit the rotation job
using rotator validate and rotator commit ioctl.

(Eg. adb shell "service call display.qservice 16 i32 70")

1. Set the video and secure flag of the layer buffer flag properly.
2. Normalize the crop rectangle of the layer to even values.
3. Handle one pixel downscale usecase, as MDP hardware dont support it.
4. Set the hint flag for each layer qualified for SDE compoisition to
notify surfaceflinger to clear the layers destination region in FB.

Rotator might be used for downscale only. Output
ROI should not swap if there is no rotation.
Do not print out error log when the input is wrong,
Lua test will treat them as failures.
Add some more logging for rotation.
Checking for over width limit should only be greater.
