if a layer is not mirrored, we now use its display
as the source for the transfrom hint calculation
instead of always using the default (main) display.
this change does two thing:
1) we make updateTransformHint take a DisplayDevice
as a parameter instead of hard-coding the
main display.
2) each time we do a transaction that could change
the hint, we go through all layers and
figure out which display should be used for their
transform hint.

The transparent region hint is computed only from view layout
locations, ignoring post-layout translation. If a SurfaceView is layed
out with no other views above it, but a view is moved above it
post-layout, that view's layout bounds would be subtracted from the
window's transparent region instead of its drawing bounds. Prior to
this change, the view would not be visible (except where its layout
bounds and drawing bounds overlap).
With this change, composition uses visible regions computed without
regard to the transparent regions. However, if all of a layer's
visible region is transparent, it will be removed from the list of
layers to composite. This doesn't fix the root problem of incorrect
transparent regions, and doesn't prevent bad composition in all cases.
But it does avoid it for some existing apps, whiel still allowing the
transparent region hint to save power in the important
fullscreen-video-in-a-SurfaceView case.

The hints were being set a little too late, so the pre-rotation stuff
wasn't quite working.

we used to have a visibleRegion object per layer, but now
it's per screen; so at somepoint the code got changed to
calculate the per-screen visible region on the stack and that's
what got passed to HWC.
we're now setting the visibleRegionScreen at each frame and
freeing at after the HWC set() call. We use the underlaying
SharedBuffer so that in most cases we don't have to allocate,
free or copy memory around.

DisplayDevices are now keyed of the wp<IBinder> the client uses.
DisplayID has now become DisplayType which is just used to identify
physical displays (as opposed to virtual displays such as wifi displays).

it's safer this way because this object owns an
EGLSurface which cannot be easily reference-counted.
it also gives us the ability to sub-class it, which
we might want to do soon.

- always pass a DisplayDevice to Layer methods that are called
on a per-display basis (to make it clear that this could be

we will only ever have a single instance of HWComposer, so
it's now an attribute of SurfaceFlinger, instead of being part
of DisplayHardware.
DisplayHardware now just represents a "display" (it should be renamed).

After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.
In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.
The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

HWComposer must abstract the HWC HAL entirely, so that the
HAL can continue to evolve (and break binary compatibility)
without breaking SurfaceFlinger. The HWC data structure had
leaked outside of HWComposer, this is now fixed.
We now have an abstract interface that provide all the
needed functionality, HWCompose provides concrete
implementations of it based on the the HWC version.

use a flag instead of pre-committing the "requested" state
to prevent propagation or "requested" to "active", which makes
things a lot clearer when reading the code.
also avoid going through the "resized" code-path when requested
size is equal to "active" size.

This change adds a crop rectangle specified in window coordinates to the layer
state. The all window pixels outside this crop rectangle are treated as though
they were fully transparent. This change also adds the plumbing necessary for
WindowManager to set that crop.

this seems to hurt performance on some GPU. this change
might negatively affect performance on other GPUs though, but
probably in less time-sensitive cases. If this becomes a
problem it might become necessary to pre-clip the geometry
(so that we don't have to use glScissor).
This improves the rotation animation quite a bit.

this optimization didn't improve performance and in fact
seemed to hurt more than anything else. it also made
things a lot more complex as it introduced edges cases
when switching to/from h/w composer.

with this changes, SF transactions are handled as soon as possible
but do not trigger updates. the update is delayed until the next

this allows us to work much better without requiring triple-buffering.

--latency-clear [name]
clears the latency data for the specified layer or for

It is now possible to say:
dumpsys SurfaceFlinger --latency
to print latency information about all windows
dumpsys SurfaceFlinger --latency window-name
to print the latency stats of the specified window
for instance: dumpsys SurfaceFlinger --latency SurfaceView
The data consists of one line containing global stats, followed by
128 lines of tab separated timestamps in nanosecond.
The first line currently contains the refresh period in nanosecond.
Each 128 following line contains 3 timestamps, of respectively
the app draw time, the vsync timestamp just prior the call to set and
the timestamp of the call to set.

we were using the "orientation" value instead of the
real transform, which may contain arbitrary rotations for
instance, and in some case ended up with a final "orientation"
that looked valid, but wasn't.
this fixes a problem on devices with a h/w composer hal where
the rotation animation looked weird.

This change fixes the NATIVE_WINDOW_QUEUES_TO_WINDOW_COMPOSER query of
Surface and SurfaceTextureClient. Surface now uses the inherited
SurfaceTextureClient implementation of this query. SurfaceTextureClient
now queries SurfaceFlinger to determine whether buffers that are queued
to its ISurfaceTexture will be sent to SurfaceFlinger (as opposed to
some other process).

Bug: 4081304
SF kept a strong reference to ISurface until the
window manager removed the surface from the screen.
This fell appart when running standalone tests, that is
when the window manager wasn't involved.
When the window manager is around, it would clean-up surfaces
even when an application died.
with this change, SF is able to do its own cleanup without
relying on the window manager.
the change is very simple, we simply don't keep a reference
to ISurface and make sure no more than one of them can
be created.
