frame of an animation indefinitely. Now we queue the buffer as soon as
HWC set() returns and gives us the release fence.

We're not using IMemoryHeap as a transport anymore,
instead we're providing a CpuConsumer and use the
IGraphicBufferProducer version of the screenshot API.
However, some GPU drivers don't support properly
a GPU to CPU path, to work around this, we use a
temporary BufferQueue on the server side for the
GL rendering, and we use glReadPixels into the
CpuConsumer (we're now using a CPU to CPU path
which is always supported).
Currently this "wrapping" is always performed,
but it can be bypassed on devices that support
the GPU to CPU path.
This also addresses a DoS attack vector on
SurfaceFlinger, where an application could
consume all of SF's filedescriptors by creating
a lot of screenshots in a row.

* changes:
Add BufferQueueInterposer and use it for virtual displays
Add DisplaySurface abstraction
Fix argument types in IGraphicBufferProducer methods
Minor cleanups/fixes before virtual display refactoring
BufferQueueInterposer allows a client to tap into a
IGraphicBufferProducer-based buffer queue, and modify buffers as they
pass from producer to consumer. VirtualDisplaySurface uses this to
layer HWC composition on top of GLES composition before passing the
buffer to the virtual display consumer.

DisplayDevice now has a DisplaySurface instead of using
FramebufferSurface directly. FramebufferSurface implements
DisplaySurface, and so does the new VirtualDisplaySurface class.
DisplayDevice now always has a surface, not just for virtual displays.
In this change VirtualDisplaySurface is just a stub; buffers still go
directly from GLES to the final consumer.

None of these should change behavior, except for removing some
incorrect log messages when using a virtual display.
- HWComposer::getAndResetReleaseFenceFd() checks the HWC version, so
no need to do that in the DisplayDevice::onSwapBuffersCompleted().
However, it should check that mFramebufferSurface is not NULL like
it is for virtual displays.
- Comment that FramebufferSurface::dump() overrides the non-virtual
ConsumerBase::dump(), and fix it so the right thing happens
regardless of the static type of the pointer/reference the callee
has. FramebufferSurface::dump() could be removed right now, but I'd
need to bring it back in a later change.
- Use the right enum for validating display type ids.
- Don't try to send hotplug events for virtual displays.
- Mark virtual displays as connected so HWComposer::prepare() doesn't
think something is wrong when it gets a non-NULL layer list.
- Remove unused FramebufferSurface methods.

When a display is added, initialize it to use an empty layer stack, so
if it is somehow visible it will show black. It will be assigned the
real layer stack -- along with a projection and other properties -- by
window manager soon. Normally a display remains blanked until window
manager has decided what to show on it, but for HDMI connected at boot
that isn't currently the case.

and the layer's transform were merged together in
computeBounds() (which really used to compute the

hwc, because it's overridden in Layer::setGeometry(), which
is why this bug was never apparent.

handle blank/unblank events, so we were losing the initial unblank
that power manager sends us when HDMI is first plugged in. This
left the display blank until you toggled the device power off/on.
(2) We were retaining fbTargetHandle for HDMI after the display was
disconnected. The value didn't get updated when HDMI was reconnected

Change-Id: If6ba33fbd1a594cd64cc5253aebf752d6ceda1c9
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.

This change adds a compile-option to use eglWaitSyncANDROID to ensure that
texturing operations that access the current buffer of a SurfaceTexture do not
occur until the buffer is completely written. It also moves this
synchronization into a new SurfaceTexture method called doGLFenceWait and
changes SurfaceFlinger's Layer class to use that method rather than performing
its own wait on the fence.

onInitializeDisplays() was posting a transaction with changes
to the display projection. Unfortunately, it only set the
display orientation field and left viewport and frame
uninitialized.
The uninitialized values flowed downstream and found themselves
baked into a bogus DisplayDevice mGlobalTransform. That transform
was then applied to some Rects which were turned into Regions
that were them combined with other Regions.
Under certain situations, the uninitialized data might have
a largish value, resulting in the creation of Regions with
components in excess of the Region max-value limit of 0x7ffffff
(note that this is not INT_MAX). Later when performing a
binary operation using the Region, the Spanner would loop
indefinitely trying to figure out how to stuff a humongous
region inside of a max-value region. Not content to try
just once, the Spanner would continue trying again and
again, pegging the CPU and hanging surface flinger during boot.
Insanity soon followed.

This change moves some common fence handling code into the base class for
BufferQueue consumer classes. It also makes the ConsumerBase class initialize
a buffer slot's fence with the acquire fence every time a buffer is acquired.

the problem was that LayerBase::setPerFrameData() was always setting
this flag. in fact there was no reason to do this at that point since
the layer is initialized to a default state in setGeometry().

If SurfaceFlinger needs to refresh the screen but the dirty region is
empty, it won't set the layer acquire fences, and stale file
descriptors will be passed to HWC commit(). Now we make sure to clear
the stale file descriptors for each layer right after commit().

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.

This change makes BufferQueue derive the min undequeued buffer count from a max
acquired buffer count that is set by the consumer. This value may be set at
any time that a producer is not connected to the BufferQueue rather than at
BufferQueue construction time.

entirely in h/w composer, in this case, we would
not set the fences for any involved layers.

Use only display tokens in the API to refer to new displays.
Don't require the caller to specify the display when creating
a surface (since in general a surface could be shown on
any display).
This is intended to be a minimum change just to update the API.
Note that SurfaceFlinger still uses DisplayID in a few places
internally that might cause some features not to work properly
when there are multiple displays (LayerScreenshot, for example).

(This reverts an earlier revert.)
HWComposer can now create IDs representing a display
it can deal with. IDs MAIN and HDMI are reserved.
SurfaceFlinger associate HWComposer IDs with a
DisplayDevice and uses that when it talks to HWComposer.
A DisplayDevice doesn't have to have a HWComposer ID,
in that case it just can't use h/w composer composition.

- we now clean-up "dead" connection in the main loop,
this entirely avoid the problem with the side effects of
releasing strong references. We now only hold on to strong
reference for the connection we will signal.
- also simplify how we build the list of "ready" connections, by
only adding them to the list when we did receive a vsync event

- one issues caused most timestamps to be reported as 0
- on rare occasions an uninitialized variable could be used
- vsync counts per connection were accessed unthreadsafely
we now have 2 lists of connections in the main loop, one just
keeps a list of strong refs to the connections because once
we have a strong ref we're not allowed to release it while
holding the lock.
the 2nd list holds the connections that have a vsync event to
be reported. all the calculations are made with the lock held.
Change-Id: Iacfad3745b05df79d9ece3719bd4c34ddbfd5b83
problem was that we were acquiring a strong reference
on Connection object with a lock held, when those
got out of scope (lock still held) their dtor
could be called if all other refs had dropped,
the dtor would acquire the lock again to
remove the Connection from the main list. boom.
we rearange the code so this doesn't happen.

fix a few bugs with external displays

so there is a lot of ugliness there
- We also need to make sure that external displays are not
blanked by default

Layers were not properly being removed because we were

When layers are removed, we must use eDisplayTransactionNeeded,
not eTransactionNeeded, to ensure that the mLayersRemoved
