In a4650a5 the concept of a maximum frame number allowance for the consumer was
introduced. A call to acquireBuffers will only return buffers when their frame
number is less-than-or-equal-to this maximum frame number. When SurfaceFlinger
is the consumer, this maximum frame number is calculated in the
onFrameAvailable/onFrameReplaced callbacks. These callbacks are called when a
new buffer is dequeued by the application. The problem is that these callbacks
are called _after_ the fence wait which is used to throttle the frame
production of client apps. When the previous frame needs a long time to draw,
those waits can potentially be a long time. As a result SurfaceFlinger won't do
any composition with the new frame until the wait is over.
Normally this isn't a big problem because there is a queue of buffers for
SurfaceFlinger to work with. However, this changes massively when a client app
is using a swap interval of zero. In this case, a new frame will instantly
replace the previous queued frame. However, SurfaceFlinger doesn't know this
until the onFrameReplaced callback gets called - which is delayed by the fence
wait. If the timing is bad, SurfaceFlinger never gets a chance to pick up a new
frame to do the composition with.
We see this behaviour on our TC development system (slow GPU) with legacy
on-screen benchmarks. Such apps are using a swap interval of zero and sometimes
frames don't get updated for several seconds. This behaviour can be also seen
on a Nexus5, although it isn't as obvious as on our TC.
The fix in this cl is to move the EGL throttling to the end of the queueBuffers
function. This ensures that if a frame gets replaced in the queue, all
consumers who installed the callbacks, get called in a timely fashion.

Reduce transparent region from a layer only if the transparent
region has valid intersection with the layer. Otherwise, reducing
a transparent region lying completely outside of the layer leads to
invalid sourcecrop values for the layer.

Compute crop and display frame for GPU composition also
in the same way it's done for HWC and compute vertices
and texture coordinates for GPU composition. This avoids
pixel shifts in output of GPU composition & overlays.

This is special solution only for emerald branch.
Changes including new const char* value/interface for sensor physical data. Sensor service and manager does not take care of content, structure or other

Devices like dory get slammed when bugreports are taken and can't
compress all the raft logs in the current 5min timeout. Our dogfooders
spend their precious time getting us bugreports and then we can't act
on them because we have broken raft logs. :(
This change bumps up the timeout in the hopes that we can get complete
logs from even our slowest devices.

NOTE: This patch does not fix the initial startup of bootanimation
* Previously HAL orientation sensor would always be replaced if the HAL
did not provide a rotation vector sensor as well. Practically no HAL
does, so the virtual sensor would always replace it.
* Add the virtual sensor only if the HAL does not provide it.
Change-Id: I50ad2cd6c60b53eddc4c6854997ec2e3dbff0d1a
* In KitKat and on most Samsung devices, the orientation sensor is
not getting registered, and makes the compass non-working in a lot
of apps. This patch enables the sensor for such devices.

The sensors API introduced a new flush() method that older binaries
won't have. For those, replace the firstFlush invocation with a
setDelay call since a lot of implementations interpreted that as
the initialization step.
We also don't want any kind of call to flush() to happen when it
isn't there, since it'll either hit a random OEM extension or
a memory address we really don't want to execute.

Reserve HWC for VDS for WFD use case. During WFD usecase, sink usage
will contain GRALLOC_USAGE_PRIVATE_WFD flag.
When HWC is avoided, all virtual displays are composed using GLES.
This means that GLES composes directly into the sink buffer and
signals the consumer. Furthermore, it is expected that any color
conversion will be handled on the consumer side.
