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

1. Do not process the display list when the display is not connected.
This is applicable mainly in the HDMI as primary use case since we
want to activate the display only when the cable is connected.
2. Do not write to HPD when HDMI is primary
HPD is always enabled when HDMI is primary, and so we rely on the
connected state (read from sysfs) to determine if the cable is
connected or not.
3. Initialize the down scale feature switch
Initialize down scale feature switch when HDMI is connected but
before we make the call to modify display attributes.

- HPD has to be set only once during boot up.
- 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.

When the display is put in calibration mode by postprocessing
tools such as QDCM, the pipes are taken over and updates need to
be blocked.

- External displays can be secure or non-secure based on HDCP
- Propogate this to the SF with the getDisplayConfig
- Non-virtual displays(pri and hdmi) are considered to be secure
- For WFD using V4L2 archiecture, read the HDCP status from the
sysfs and update accordingly

When an HDMI display is connected, we report all the available
configurations to the framework by translating the EDID data.
This information can be queried, and subsequently used to change
the frame rate of the HDMI display.
Note: this change does not provide support for changing the resolution
of the HDMI display.

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.

- 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

DMA multiplexing is supported on WB mode only.
For primary the DMA multiplexing should be avoided
as it can lead to hung rotator.
This can happen when the DMA is being unset from overlay,
while at the same time rotator gets configured.

WFD teardown was required when HDMI is connected on V4L2
architecture. This is because WFD connection is using HDMI
piggyback connection. Since SurfaceFlinger can honour only
one active external display, we have to teardown WFD
connection to process HDMI connection.
This is no longer applicable on VDS architecture. WFD connection
is established using Virtual Display adapter.
WFD Stack listen to HDMI broadcast event and initiate wfd teardown.

Add support for rotator downscale. This is enabled from 8994 onwards
Constraints:
--Downscale should be a power of 2, max upto 32
--Both directions should have equal downscale
--{src_w, src_h} mod downscale = 0
--No BWC
--No Interlaced video support
The rotator's destination rect is modified to reflect the presence of
downscale. Any downscale calcs should be done only after adjusting
crop to meet rotator's requirements.
Smaller downscale is used if we need to chop off any more than 1
line or pixel.

1. Use MDP rotator to rotate RGB layers which are rendered by software
2. Restrict total number of rotator sessions to 4 for all displays
3. Disable RGB layer rotation for all MDP versions < MDP5

MDP bandwidth limitations can be avoided, if the overlapping region
covered by the smallest layer at a higher z-order, can be composed
on a render buffer using Copybit, and then it can be queued to MDP
along with other layers. It helps to improve performace by avoiding
GPU Composition in use cases like Home Screen pan. To enable this
feature, set system prop "persist.hwc.ptor.enable" to "true" or '1'
and enable Copybit HAL compilation.

* Revert commit 7a495b3caa
"hwc: Call blank IOCTL on virtual as well if it is connected."
* On issuing suspend when WFD is connected, display-hal
receives both pause and blank calls. Calling StopTerminate
ioctls on WB(WB is not active on VDS pause) once blank
is issued on Primay(i.e when iommu is detached) doesn't free
up the buffer nodes resulting in orphaned memory blocks.
* To avoid this, allow WB to be active even during
VDS pause state so that when StopTerminate calls are made as
part of VDS teardown, display will be in unblanked state and
iommu would have been reattached, thus freeing up the buffer
nodes.
* Doing this doesn't clear all references to WB fb node during
VDS pause. Call display commit to unset the pipes rather than
relying on the refcount

If the display list contains single layer and that layer

Extends partial frame update support for split displays by calculating
changing region(ROI) independently for each half of the screen. In case of
only one half updating, display driver shuts down the DSI/MDP mixer control
of the non updating half.
Maintains two ROI's for each display. In case of Non-split
displays, only left ROI is updated.
