- Populate frame_rate in rotator set, so that driver
can vote for honest BW for rotator based on frame rate.
- If metadata contains source fps, frame_rate will be set
to source fps, else it will be set to primary refresh rate.
- frame_rate will be populated for primary with
source fps from metada, only when secondary is not active.

- Instead of assuming the default format(RGBA_8888),
read FB format from driver and pass the info to SF
- For now, this is limited to primary and HDMI only.
WB FBformat is assumed to be in RGBA_8888
- If FB doesn't have alpha channel, disable mixed mode

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.
adb shell service call display.qservice CODE ARGS
ARGS can include config index and display (only primary supported)
setActiveConfig():
adb shell service call display.qservice 25 i32 INDEX i32 0
getActiveConfig():
adb shell service call display.qservice 26 i32 0
getConfigCount():
adb shell service call display.qservice 27 i32 0
getDisplayAttributes():
adb shell service call display.qservice 28 i32 INDEX i32 0

1. Add support to set HDMI to 3D mode
2. Add binder API to force 3D mode
3. Switch to 3D mode based on metadata

With source split enabled:
1) When both LEFT and RIGHT pipes gets reused pipes, we use their
pipe id's to compare their priority and swap them as needed.
2) When both LEFT and RIGHT pipes needs to be newly allocated, we
let driver take care of the priority as long as both pipes are
of same type. If different, we swap them according to the pipe
type priority.
3) When LEFT is reused and RIGHT needs new allocation, we swap
them only when they need same pipe type and LEFT has the
pipe with lowest priority.
4) When RIGHT is reused and LEFT needs new allocation, we swap
them only when they need same pipe type and RIGHT has the
pipe with highest priority.

1. Add support for UBWC allocation in the Gralloc APIs for aligned
width, aligned height and buffer size. A client can request for UBWC
allocation by sending UBWC specific HAL pixel format or by setting
GRALLOC_USAGE_PRIVATE_ALLOC_UBWC flag in the usage flags.
2. Gralloc allocates UBWC aligned buffer, only if format is supported
by GPU and MDP and no CPU usage flags are set. Otherwise it allocates
linear buffer.
3. If UBWC conditions are met, gralloc sets PRIV_FLAGS_UBWC_ALIGNED
in private handle flags to tell client that allocated buffer has UBWC
alignment. This flag remains unset by default.
4. Add helper functions in gralloc to calculate UBWC meta buffer size
for RGB* formats.
5. Add UBWC HAL pixel format HAL_PIXEL_FORMAT_YCbCr_420_SP_VENUS_UBWC
which has been defined by Video module.
6. Add AdrenoMemInfo api to query, if GPU supports UBWC for a format.
7.MDP driver expects UBWC specific pixel format defined by MDP header.

Not necessarily the max width supported by the MDP pipe and mixer
need to be same. HWC has to make the decision for using one OR
two pipes per layer only based on the max width supported by the
pipe not the mixer.
Change-Id: I5a2495d07de1b6f54ef64d9140c909f0f4cef914
The layer clock is dependent on vertical downscaling and horizontal
dest width (pixels). When comparing to mixer's requirements,
line-time can be ignored since it is common to both pipe and mixer.
Also since mixer's scale is 1, layer's downscale * dest width needs
to be compared to mixer's width.

For PROTECTED but NON SECURE layers set MDP_SMP_FORCE_ALLOC flag
to allow SMP allocation and prevent GPU fallback
In Such cases if video resolution changes dynamically
it fails to display layer due to GPU fallback.
Use this flag for FB layer composition and depricate
MDP_BACKEND_COMPOSITION flag.

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.

3. Manipulate the external display position if external orientation
is set for external display.

Read the maximum width mixer can output from drivers
and consider this in identifying if dual pipes are required
to support a layer. So far above 2K dimensions we are using dual
pipes, but 8x39 mixer output can be upto 2560. So there is no
need of dual pipes as long as pipe data is less than this limit.
Compare layer/panel resolutions against this limit to deduce
if there is a need for dual pipes or split.

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.

Source Split layers always if the driver indicates so by setting
the src_split_always in the capabilities sysfs node.
This is applicable to layers whose width > mixer's width, since
MDP clk rate is dependent on max(mixer_width, layer_width).
This feature can be enabled if the panel height is more than a
certain empirically derived value. Splitting always in those
cases can help with a lower voltage.

Remove opaque types like size_t, uintptr_t, intptr_t to support
32bit and 64bit processes together.
When a 64bit process creates a handle and a 32bit process validates
the incoming ints against expected ints, opaque types lead to
different and mismatching values.
Always use unit64_t for base address for 32bit and 64bit SF.
Use unsigned int for offset and size, since ION uses that.

* Mdss driver supports DMA-Multiplexing on wb interface
for certain targets. Add overlay get function to query
this info during pipe allocation for wb.
* UI Scaling on external is not supported on certain
targets due to the lack of availability of pipes with

Clear overlay and layer-rot map from the top level caller of
composition, rather than from the place of actual intermediate
failure. This makes sure, even in cases of GPU comp failure,
overlay and layer-rot maps are cleared and eventually pipes unset.

If using source split to stage 2 pipes on the same mixer stage,
the left pipe needs to be a higher priority than the right.
Add API in overlay to compare pipe priorities and use this in
source split config to stage pipes accordingly.

For dual DSI panels, when enabled partial update AND framebuffer rect
optimization, it is not necessary to update both the halves of
the framebuffer every frame. This channge adds support to update
framebuffer based on the updating region generated.
Change-Id: Ia63a8b9ac0e915c04e06122a16471ee18b5a8272
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.

Send the entire frame (array of overlays) to driver, so that it would
check pipes params and the whole frame wrt bandwidth and SMP.
Now, the overlay's commit API just prepares an overlay object but
makes no ioctl calls.
If the driver finds the frame, as a whole, to be not ok, the
validation fails and overlay/hwc return silently.
If a certain overlay object is mis-configured or pipes are
unavailable, the driver sets the number of objects it processed.
Overlay uses this to dump the incorrect config.
