1. Add one binder command to display.qservice to serve the
binder requests received from SDK.
2. Each subcommand will be corresponding to one command
handler. Command handler will pass the requests to
qdcm library.
3. Dynamically load qdcm library, where all apis are
implemented.
4. apply default mode function will be invoked once
bootanimation event is detected

When client prefer to enable PU(partial update) over PP(post
processing), delay enabling PU until PP turns off its
features completely. This change introduces hand shaking flags
between PP and HWC through binder calls. When requested to turn
on PU, we notify PP through the sys_fs node. When PP is done
shutting off it features, it acknowledges back to HWC to actually
turn on PU.

Add support for panel resolution switch. This feature makes use of
the Linux modedb feature that lists available modes in
/sys/class/graphics/fb0/modes and accepts a mode change when written
to /sys/class/graphics/fb0/mode
Clients can link to APIs exposed in display_config.h, these
internally resolve to binder calls into HWC. For debugging, mode
changes can be made over binder using shell commands.

** 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.

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.

scalable across chipsets.
- Add binder support to change the max pipes per layer value
dynamically for MDP comp.

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

This is enabled via binder as:
$adb shell service call display.qservice 15 i32 4 i32 1

1 is to enable

Provides a way to enable/disable dumping of virtual display
frames at runtime via binder. The dumping needs to be enabled
from a priviliged shell.
For example,
$ adb shell service call display.qservice 15 i32 3 i32 1
Here 15 is the integer code for DYNAMIC_DEBUG in IQService.h
The first parameter 3 is for DEBUG_VD
The second parameter 1 is to enable.

Provides a way to enable/disable logs at runtime via binder.

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

* 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.

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.

This API is meant for system level users that need to get/set
various display attributes that are normally not available via
the regular Android framework channels.
Initially the APIs exposed are to check HDMI status, get display
attributes and set HSIC data.
Only physically connected displays are supported for now.

The current binder implementation is inflexible when it comes to
adding new input/output parameters. It also needs a lot of
boilerplate code written when adding a simple enable/disable type
command.
Instead, let clients specify the parcels they want to pass and
unparcel them at the end points only.
Please note that it is assumed that all commands coming in
need the same permission checks. If this is no longer the case,
some commands need to be split out on the receiver end in
IQService.cpp.
This change also simplifies the code end clients need to write.
They should be able to include QServiceUtils and call a single
function to set the binder up and make the call.

Remove the unnecessary blank lock, mdp comp lock, secure lock.
Rename the ext lock to a more appropriate draw lock.
The mdp comp lock is at an incorrect place and causes unwanted
objects to show up in dumpsys, since configDone hasnt cleaned
them up yet.
dump(), blank(), draw() should all acquire a common lock.
draw() includes prepare() and set().

- According to the value set, the FB_TARGET for External will
be rotated and positioned as per aspect ratio on Ext
- For YUV(video layer) it just calculates the position, as the
rotation should be the source orientation
- This feature is supported only for low resolution panel.

DSI command mode panels do not need to be refreshed on each

Add a client interface which interfaces with hwc.
qservice upon receiving IPC, provides a callback notification to the qclient
which does appropriate stuff in hwc.
In future, qservice can safely be even made a separate process with no changes
to exisiting code. This was not true earlier owing to the hwc pointer held by
qservice forcing it to be in the same process that hwc is in.
