1. Remove hwc_context_t from libexternal since this is a construct
that should only be used in libhwcomposer.
2. Clean up redundant code by creating utility functions to
a. open a sysfs node in a given mode
b. improving EDID mode storage/manipulation
c. creating/destroying composition objects
3. Add utility functions to
a. get the connected state of the external display
b. determine which interface the external display is connected to
(primary or external)
c. activate the hdmi interface by setting the resolution via an
ioctl
d. update/reset external display information when a device
connected/disconnected

- 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.

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This is no longer applicable on VDS architecture.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.

1. Detect and account the number of secure RGB layers present.
2. Mark secure RGB layers for MDP comp in cache based stratergy.
3. If full MDP comp and partial MDP comp fails, Mark secure RGB
layers for MDP composition.
4. In partial MDP comp reject load based composition, if secure
layer is present to avoid GPU composition.
5. Disable idlefallback feature if secure RGB layer is present
to avoid GPU composition.

Remove support for overriding a layer's z to set it up for foreground.
This is unused and can be achieved using pipes staged at required
z-orders.

External only feature is completely handled in surfaceflinger, remove
unwanted code churn related to external only feature from display HAL.

* A non-updating layer requiring rotation, can make use of
the older rotator buffer written when the layer got first
updated, rather than invoking a new rotator cycle.
* A rotator play is avoided in cases where incoming layer
buffer fd, offset, whf, src-rect, dst-rect, etc are similar
to that of the previous input layer to the rotator.
* For ex: In a usecase where video layer updates happen at
30fps and all other asynchrous UI updates happen at 60fps,
instead of the traditional 60 calls of rotator play per sec,
we now do only 30 thereby saving rotator bandwidth.
* Property "debug.rotcache.disable" can be used to disable
this feature.

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.
Change-Id: Id07d62fefa3213035f16cca49497800716484a95
* Limit the number of rotator sessions to 4 both in
LayerRotMap and RotMgr structures
* Make use of MDPVersion getter fuctions to check
for maxMixerWidth and maxDownScale supported by MDP

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.

DirtyRect for a layer is generated w.r.t to its buffer

ROI.

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.

* 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.
