1. For PTOR layers, MDP needs to be configured with width, height
and format of the Copybit render buffer, otherwise it will lead to
artifacts due to incorrect render buffer reads, when PTOR layer
handles have un-equal strides.
2. Remove render buffer offset for a PTOR layer and configure MDP
with modified source crop, based on its position on render buffer.
3. A layer cannot qualify for PTOR feature, if none of below layers
intersect with it.

Provides a way to enable/disable logs at runtime via binder.
The logs need to be enabled from a priviliged shell.
For example,
$ adb shell service call display.qservice 15 i32 0 i32 1
Here 15 is the integer code for DYNAMIC_DEBUG in IQService.h
The first parameter 0 is for DEBUG_ALL
The second parameter 1 is to enable.
Hence, this command enables all debug logs.
Another example - this command enables vsync logging
$ adb shell service call display.qservice 15 i32 2 i32 1

Currently for Mdss rotator we manipulate the layer buffer dimensions
to be equal to what rotator's destination dimensions would be, so that
these could be fed to MDP. Instead, this patch introduces APIs in
rotator so that hwc can directly query destination crop, width, height,
format from rotator.
This also simplifies the updateSource() and configRotator() helpers.

- Consider two smallest layers for PTOR feature which uses MDP comp.
- These two layers are rendered on a buffer and are queued to MDP
to acheive full MDP Composition
- This helps to acheive performance enhancement

1. Add hook to dump the layers going to VDS based virtual display.
2. Furthermore, add utility function to dump the frame buffer and
WB output buffer. This will be enabled via a system property
debug.hwc.enable_vds_dump
Once dumping is enabled, the dumps can be extracted from
/data/vds.fb.FORMAT.XRESxYRES.raw
/data/vds.wb.FORMAT.XRESxYRES.raw

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.

* Provide a binder interface call for wfd module
to inform display about the start/stop/pause/resume
of wfd session.
* This is needed for wfd-hdmi synchronization in
case of v4l2 wfd solution. If hdmi is plugged
in during v4l2 wfd session, display-hal waits in
uevent thread for wfd teardown notification from
wfd module, before going ahead with configuring
external display.
* For VDS WFD solution, display-hal waits in uevent
thread for wfd-teardown to be signalled from
the composition thread.

Add support to turn the MDP downscale feature ON through the

1. Screenrecord and WFD use virtual display and encoder.
Since HAL supports only one virtual display, we need a
definite way to distinguish both use-cases.
Failure to differentiate will break Screen record + WFD
concurrent usecase.
WFD stack will set this usage flag and SF will query the usage
flags to differentiate WFD and screenrecord usecase.
2. Deprecate GRALLOC_USAGE_PRIVATE_EXTERNAL_CC and
GRALLOC_USAGE_PRIVATE_EXTERNAL_BLOCK flags as these are no
longer used.

* In some use-cases, it is possible that there are
no AppBuffer layers on the external/virtual layer-list
during which all the pipes will be allocated to the
primary. When layers do comeup on external/virtual
layer-list, subsequent overlay sets fail.
* This change ensures that in such cases, we invoke a
padding round on all the displays to free up the
hw resources which can be used in subsequent cycles.

Vpuclient is the client side for VFM in hwc. It follows the
similar pattern of prepare and draw. It has 2 step prepare
including: setVpuSession and prepare. The setVpuSession function
passes all the layers from the SF list to VFM, which marks
the layers that it can support. After this, the layer
allocation/configuration is done, and finally in prepare the
allocated pipes are passed down to VFM. The draw function
passes the handle to the VFM to draw the video layer.

Added a new layer flag: HWC_VPU_PIPE to indicate that the layer
will be drawn by VPU. There is a corresponding MDP pipe
flag: MDP_VPU_PIPE, which should be set for the VPU layers to
indicate the layer will be drawn by VPU, so that MDP driver does
the appropriate settings to allow this process.
