set to N>1 (ie: receive every N vsync), SF process' is woken up for
all of vsync, but clients only see the every N events.

to request the next one. currently the call-back is a binder IPC.

the working theory here is that a Surface object has become non-promotable
because it lost its last reference; later Surface::readFromParcel is called
the previous surface is found in the cache, but can't be promoted. this causes
a new Surface object to be created which will promptly try to connect to the
CPU_API -- this in turn will fail because the previous (now dead) surface is
still connected.
To fix this, we make sure to disconnect from the SurfaceTexture when
Surface[TextureClient] is destroyed.

This change fixes an issue involving buffer reallocation and the
ALLOW_DEQUEUE_CURRENT_BUFFER mode in SurfaceTexture. The bug happened
when the buffer slot currently attached to the GL texture was selected
for dequeuing, but the dequeue operation caused the buffer to be
reallocated. Because the buffer is new, the image producer could fill
the buffer and queue it before an updateTexImage call, which would
result in the "slot %d is current" error in queueBuffer.
Bug: 5631630
Change-Id: Icdd8bc5cad3c7db43953446d9be2603aaea11a8d
Surface Texture dequeue logic is modified to return the oldest of the
free buffers to Client on dequeue call.
Currently dequeue method is returning the first buffer index which is free.
The parsing is done in ascending order of the buffer slot indices.
This leads to returning the buffer which has been just queued to composer,
and hence display, and this defeats the purpose of having minimum dequeue count
as 2 in asynchrnouse mode.
This is fixed by checking all the free slots and returning the oldest buffer.

will do this are camera and video decode. Previously it was thought

may make sense to use synchronous mode (with 2 buffers) to reduce memory
usage.

This change fixes how the Android EGL layer overrides the size and
format of an ANativeWindow in eglCreateWindowSurface. The new behavior
is to leave the size untouched when overriding the format. The previous
behavior was to reset the ANativeWindow to use the default size set by

It also adds two new 'perform' methods to the ANativeWindow interface:
set_buffers_dimensions and set_buffers_format, and redefines the
behavior of set_buffers_geometry to be the combination of these two new
methods.
Additionally, this change adds an error check for the return value of

This change adds a test to verify that proper synchronization is done
when using SurfaceTexture to use CPU generated images as OpenGL ES
textures in 'synchronous mode'. Synchronous mode is particularly tricky
because SurfaceTexture will allow the buffer that's currently bound to
the GL texture to be dequeued. We rely on Gralloc's lock function to
block until this buffer is no longer being used by the OpenGL ES.

This change moves the point at which queued buffers get consumed to
after any error checks that could cause updateTexImage to fail. This
way, if updateTexImage returns an error the buffer remains queued.
This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class. The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer. This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed. Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.
The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves. This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.

This change the binder protocol between SurfaceTextureClient
and SurfaceTexture. dequeueBuffer() now takes the requested
parameters for the buffer. SurfaceTexture decides if the
buffer needs to be reallocated and does the allocation
if needed. In that case it returns BUFFER_NEEDS_REALLOCATION
to tell SurfaceTextureClient that it needs to call
requestBuffer (which all parameters have been removed) to
acquire a pointer to the buffer.
dequeueBuffer and requestBuffer could be folded into a single
IPC call, but we chose to optimize the case where buffers are
not created and avoid some complexity in the marshalling code.

This leak was intentional, it was there to deal with the fact that
some gralloc implementations don't track buffer handles with
file-descriptors so buffers needed to stay alive until there were
registered, which is not guaranteed by binder transactions.
In this new implementation, we use a small BBinder holding a
reference to the buffer, which with tuck into the parcel. This forces
the reference to stay alive until the parcel is destroyed, which
is guaranteed (by construction) to happen after the buffer is
registered.
this allows the public facing API to not expose the previous hack.

Camera HAL change: Expect vendors to set these timestamps using

autogenerated by SurfaceTextureClient if set_buffers_timestamp() is
never called, but such timing is likely not accurate enough to pass a

number of buffers that must be left un-dequeued during the steady-state
operation of the ANativeWindow.

This change passes a reference to the IGraphicBufferAlloc binder object
to SurfaceTextureClient objects. When STC objects are created they
query their associated ISurfaceTexture object for the
IGraphicBufferAlloc that the SurfaceTexture uses to allocate buffers.
Having the SurfaceTextureClient hold this reference prevents the
GraphicBufferAlloc in SurfaceFlinger from freeing the allocated buffers
before the SurfaceTextureClient is done with them.

This changes the ANativeWindow API and the two implementations to reset
the window's crop rectangle to be uncropped when the window's buffer
geometry is changed.

This is a temporary WAR for the case where dequeueBuffer is called when
all the buffers owned by a SurfaceTexture are not available - either
they're the current texture buffer or the next one. Currently, an error
is returned in that case, and this change just prevents that error from
being logged. In the future this will be fixed to not return an error
in that case.

This change implements the onFrameAvailable callback for the
SurfaceTexture java class. It includes the C++ SurfaceTexture code as
well as the JNI and Java code to enable the callback.

This change fixes a bug in SurfaceTextureClient where GraphicBuffers
were being compared using pointer comparison rather than handles.

This change fixes a horrible hack that I did to allow application
processes to create GraphicBuffer objects by making a binder call to
SurfaceFlinger. This change introduces a new binder interface
specifically for doing this, and does it in such a way that
SurfaceFlinger will maintain a reference to the buffers until the app is
done with them.

This change fixes a bug that allowed the most recently queued buffer to
be returned by dequeueBuffer. At the next updateTexImage call, the
dequeued buffer would be set as the contents of the texture even though
the client could be writing to it.

This change adds support for the setCrop and setTransform methods of the
SurfaceTexture C++ class. The crop and transform for the current
texture will be accessed by applications as a single texture coordinate
transform matrix.

We need to reset mCurrentTexture and mLastQueued in setBufferCount
because it frees all of the buffers associated with the buffer slots.

This change adds the C++ implementation of SurfaceTexture and related
classes. The goal of this is for a SurfaceTexture to be passed to
camera service or Stagefright in place of a Surface to allow camera
preview or decoded video frames to be streamed to an OpenGL ES texture
that an application can use.
