This is a helper function that will return false if the given format is
supported by adreno drivers but not supported in GPU HW. For these
formats, adreno will use software color conversion routines to convert
them to acceptable format by the GPU HW. This may be required if we
want to avoid creating texture for certain formats when not absolutely
necessary. Could be defaulted to return true depending on a compile
time flag.

Display/libhwcomposer:Add intermediate stretch for low resolution clips
Copybit module has a limited stretch to scale a clip.
Hence we need to do a intermediate stretch before going
to final stretch.

The mandate for the width and height to be even is only for the YV12
format. Add this check only for the YV12 format.

The x and y coordinates are derived properly from clip and dest rect with this fix.
- Even if rotation is involved, we need to start reading from the same point.
- Do scaling operation on the delta, and then add the source left and top values.
- If we scale the result of addition, we will not be reading source correctly.

Assign the correct blending value

incorrectly assigned to zero
for cases where blending was not needed.

Refactoring is necessary to attain flexibility in setting mdp overlay params
at runtime, while using composition bypass.
This change includes new APIs for setting crop rectangle, display params and
commiting mdp params, namely setCrop(), setDisplayParams() and commit(),
respectively.

Check the is_fg flag along with the other parameters in checkOVState.
This is done so that the is_fg flag can also be updated even if there
are no updates to the geometry.

When performing the setup for bypass operations, check the number
of bypass channels that are in open state. If the count does not
match the number of bypass layers, close all the bypass channels.
This is done to prevent the overlay channels from going into an
inconsistent/undefined state.

Add the following optimizations for the temporary buffer:
- Initialize the temp buffer only when required.
- The temp buffer is not deallocated/released unless there is a
change in size of the temporary buffer.

If module composition type is MDP or C2D and we have a skipped layer
(usually layers without backing buffers, layers with "invalid"
orientations or debug layers), mark every HWC layer below this layer
for GPU composition.
This logic is needed because ICS SF composes a bunch of z-ordered
HWC_FRAMEBUFFER (GPU) layers first and then the remaining bunch of
z-ordered HWC_OVERLAY layers last which breaks the overall z-ordered
layer rendering requirement. This logic also holds valid for 2-layer
bypass in ICS.

Validate the previous overlay and bypass handles before unlocking
the buffers. The reason for doing this, is that in certain use cases,
after the previous handles are stored, the buffer gets destroyed and the
handle is now invalid. The HWC however doesn't know that the handle is
invalid and tries to unlock the handle, resulting in a failure.

Qcom specific private flags have been moved to libQcomUI. Use these
flags flags in the hwcomposer.
Change-Id: I9898dd11a7fff72678fa1f744454fcf310507a63
* changes:
libQcomUI: Add support for qcom specific layer flags.
libQcomUI: Add support for updating the buffer geometry
Display: Add libQcomUI
liboverlay: Add support for interlaced content in updateOverlaySource.
Android YUV formats are aligned to 16pixels, while C2D requires 32pixel
aligned. Use a temp buffer to do the conversion.
Change-Id: Iff93b56e152460255d480dc703dabbcdb3697995
Add support for updating the qcom specific layer flags. Add support for
getting the per frame HWC flags based on the layer flags.

Add support for updating the buffer geometry without any reallocation
of memory. The buffer geometry is updated in the GraphicBuffer as well
as in the buffer handle.

Add libQComUI which is used to perform operations specified by
SurfaceTextures.
The operation currently supported by this library is SET_BUFFER_SIZE
which deallocates and reallocates memory if the size allocated for the
buffer does not match the size requested by the client.

is interlaced.

Since composition bypass uses MDP overlays, which
need physically contiguous memory, we cannot use
bypass in cases where the buffers are using ashmem
or other virtual memory. Hence, avoid bypass in
such cases.
