ping-pong split needs source split to be enabled to stage two
pipes of a layer in the same Z order. This change adds partial
update support to generate ROI when source split is enabled.
When configured, ping-pong-split splits the layer mixer output equally
across two DSI's. To meet this limitation, the generated ROI is
adjusted to have equal widths from the panel mid point.

- Set the perf hint when there is only one updating layer, which helps
in reducing cpu params and thus reduce power.
- This feature is enabled with the property persist.mdpcomp_perfhint,
which is set to a positive value, which will be the window of frames
before the perf hint is set

Dynamic partial update feature enabled post processing OR
partial update based on client preference. In case of framework
reboot, HWC needs to preserve the last set preference of these
features.

Expose binder API to control partial update dynamically. Partial
update feature cannot co-exist with post processing features
dependent on histogram data. With this API, OEM's can set their
preferences on these features on use case basis.

Add support for configuring the maximum mdp layers on secondary
via persist.hwc.maxseclayers property. The default value is 1.
Move the check for max allowed layers to postHeuristicsHandling
rather than it being a part of strategies itself.
Change-Id: Icae6cb7e400fd95f60e0b3eb64e6b768e4dbd861
- Read MDP sys_fs node for blending stages supported per mixer
instead of hard cording the value. This makes the implementation
scalable across chipsets.
- Add binder support to change the max pipes per layer value
dynamically for MDP comp.

1. Remove AIV video mode composition stratergy and reuse video only
composition stratergy to achieve the same functionality.
2. Drop all non AIV layers from the external list at the start of MDP
composition prepare and fall back to video only composition.

1. This feature is targeted to remove any window/pillar boxing on
external display when zoom mode is enabled.
2. Preserve the aspect ratio of the external display by cropping and
upscaling the tagged video layer during video playback on external.
3. User can tag the layers to be displayed on external display.
4. Set sys.hwc.windowbox_feature to true to enable this feature
Assumptions & Limitation:
1. Tagged layers for external display will also be displayed on
primary display along with untagged layers
2. When zoom in mode is enabled, source crop left and source crop
top of a tagged video layer is always assumed to be set to
positive integer value. So pinch zoom feature or zooming in top
left corner of the video use case cannot be supported.
3. Except tagged video layers, all other tagged UI layers will
use GPU for composition on external display, So all tagged UI
layers cannot be secure layer.
4. Rotation animation cannot be supported for this feature.

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

- 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. 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.

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

- 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. 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.

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.

There is no need to re-program the H/W, if the frame geometry of all

by avoiding re-configuration of HAL and driver, if it is not needed.

Add support for returning pipes based on capabilities.
getPipe() API takes in pipe specifications like format class,

If using source split to stage 2 pipes on the same mixer stage,

pixels.

Add support for SourceSplit. The mixers are abstracted from hwc.
There would be no translations to mixer understood destinations.
1) If a layer's crop and position are < 2048, only 1 pipe can be used
irrespective of position.
2) Else 2 pipes can be used with the layer equally split, without
regard to position.

Pipe estimation was necessary when the unavailability from overlay

4. VDS solution is not verified as it requires some dependent changes.

Set default idle timeout to 70ms (~4 cycles on 60fps panel + some extra)
from the earlier 2sec.
The GPU timeout is around 80ms after which it turns off its rail,
clock and bus vote. So having a draw cycle before that is beneficial

Use the low and high bandwidth values exported from driver per target
Use the low bandwidth value when the system has at least 1 video

Do not use the framebuffer handle to get size, since the handle may
be null.
