- Identify secure display layer in the hwc_list
- Need to set both SECURE_OVERLAY and SECURE_DISPLAY flags for the secure
display layer
- Disable idle timeout for secure display usecase, as GPU should not be
accessing secure display layer

This change adds support in HWC for MDP partial update applicable
only for command mode panels. Presence of MDP FB (GRAM) in
command mode panels allows MDP clients to update only the updating region
of the frame as rest of the frame will be cached in the GRAM.
HWC calculates the updating region of a frame (ROI) by deducing
outer bounds of its updating layer destinations. Layers not lying
within the calculated ROI will be dropped from the composition
since its illegal to program MDP pipes for non participating layers.

With in hwc list of layers if a layer above is opaque,
deduct the opaque layers crops from all the layers below
in z-order if deduction is possible with out creating
any hole.

Stub implementation of VPU in HWC.
This commit passes through binder calls from HWC
to the VPU library. It also has stub prepare/draw calls
in the VPU client object which can be used to configure
VPU in the composition cycle.

- needsScaling does not check for scaling required in left & right
mixers when the crop values are sanitized. So it leads to issue
if DMA pipes are picked-up as high resolution layer does not need
scaling but left or right mixer configuration needs scaling after
the split.
- needsScalingWithSplit takes care of this with checking for the
sanitized cropped values.

Writeback for assertive display feature is needed only for
split displays and only if ro.qcom.ad is set to 2 by OEM.
This patch removes the unnecessary code and adds the relevant
conditional checks for split displays and property value
Change-Id: Ic36f28441d1a6e93132316b33fe1cf98a6e1efe4
A display could be split if its dimensions exceed 2048 or in case
of primary if we make it so via device tree property.
Add an API to find if a display is split. Use this API instead of
going through a set of conditions in various use cases.
Rename the HighRes, LowRes objects to a more appropriate Split and
NonSplit respectively

For split source crop of YUV ensure that Left and Width
(thus Right) of each crop is even.
For split source crop of RGB and YUV ensure that Crops have
no gaps (i.e right of left-crop = left of right-crop)
Enable overfetch of pixels in the center, for split layers,
to get a smooth upscale

Enable sync-pt for rotator on B-family. The already existing

1. During PAUSE event, trigger an invalidate frame
which will unset the pipes (in draw call) and invoke
display commit as part of hwc_event thread.
This is required to avoid iommu page faults arising when
WFD encoder is in the middle of configuring buffers
and providing to Writeback as part of RESUME event and
Display HAL tries to invoke display commit as part of PAUSE.
2. Allow usage of rotator for Primary when WFD is in Pause
state.
The above changes are required to support secure/non-secure
video playback on HDCP WFD session and Pause/Resume.

Do not allow video if it requires pre-rotation and DMA pipe
is configured in LINE mode. Fall back to GPU in this usecase.
This is not applicable for wfd on 8x26 since Driver supports
both multiplexing of DMA pipe in LINE and BLOCK mode as same
mixer control block is used for rotation and writeback mode.

- In Buffer mirror mode, the output on the external should be rotated
based on the primary orientation.
- this is used for the side sync feature.
- buffermirrormode has higher precedence over external orientation

On WFD/HDMI connection, if the configured resolution is less than
Primary Resolution, Display HAL does the following:
1. sends hpd notification to SF with primary resolution.
2. configures MDP pipes with configured Resolution.
This is done to improve UI quality as MDP has better downscale
filter options compared to GPU.

HWC 1.2 API passes down the plane alpha and the blending
operation to apply. Pass this information to the MDP.

Add assertive display support to hwc. This feature takes effect when
node /sys/class/graphics/fb*/ad is present. This signifies that that LM0
is being used with fb* for writeback.
When a video playback begins we write "1" to this node to indicate to
post processing that a writeback will happen. Likewise a "0" is written
to this node when playback stops.
The original contents are worked upon and the modified output is fed
via writeback to either rotator or mdp as appropriate.
The feature doesnt trigger when either:
1) Buffer size exceeds 2048
2) External display is connected
3) Multiple yuv streams are present
When this mode is active, MDP comp is applied only to yuv layer.

If the left split is not published by the driver then the default should
be even split. This was missing from the configuration in utils. This is
already taken care of in framebuffer configuration and mdp composition.

Increase precision from float to double in triming calcs.
This improves the output. We need this since ultimately
we assign to int which would truncate excesses. With float
due to lower precision, we end up slightly lower than an
integral value.

Implement sync for rotator.
If a buffer is rotated, it can be used by producer soon after
rotation (and it wont have to wait until vsync).
Mdp waits for the rotator buffer's release fence to signal
to start display.
Hwc waits for previous access to rotator buffer by MDP to finish
before using it

Crop swapping is being done on V flip, rather it should be done

Add support for unevenly split primary displays.
The driver provides info about the split via msm_fb_split sysfs node
For external we assume even split. If driver doesn't specify any split
for primary, we default to even split.

When WFD is connected to 8x26
1) On Video transition, have 1 padding round if external connected.
Required to shift pipes across mixers.
2) Request DMA pipe always for FB on WFD.
Necessary for rotation + writeback
3) Disable non-worm-hole calcs on external (because of 2)
4) Disable action-safe calcs on external (because of 2)
