* ANativeWindow: add query for the concrete type.Jamie Gennis2011-03-142-1/+13
| | | | | | | | This change adds a query to the ANativeWindow interface for getting the concrete type of the ANativeWindow. Bug: 4086509 Change-Id: I64aa86d72fbca3b52a98e1fc35608737781a3178
* SurfaceFlinger: Respect the PROTECTED gralloc bit.Jamie Gennis2011-03-101-6/+59
| | | | | | | | | This change makes SurfaceFlinger treat layers for which the active buffer has the GRALLOC_USAGE_PROTECTED bit set as if they have the 'secure' flag set. Change-Id: Ic60b6513a63e4bb92ec6ce9fd12fd39b4ba5f674 Bug: 4081304

| | | | | | | | | | | | | | | | | | | | now that we removed the notion of a "inUse" buffer in surfaceflinger a lot of code can be simplified / removed. noteworthy, the whole concept of "unlockClient" wrt. "compositionComplete" is also gone. Change-Id: I210413d4c8c0998dae05c8620ebfc895d3e6233d
* | fix [3361121] hang in glClear() - device unresponsive, OTA failsMathias Agopian2011-01-181-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generally we never want to lock a buffer for write access if it is at the "head" on the surfaceflinger side. The only exception (1) is when the buffer is not currently in use AND there is at least one queued buffer -- in which case, SurfaceFlinger will never use said buffer anymore, because on the next composition around, it will be able to retire the first queued buffer. The logic above relies on SurfaceFlinger always retiring and locking a buffer before composition -- unfortunately this didn't happen during a screenshot. This could leave us in a situation where a buffer is locked by the application for write, and used by SurfaceFlinger for texturing, causing a hang. Here, we fix this issue by never assuming the exception (1), it was intended as an optimization allowing ANativeWindow::lockBuffer() to return sooner and was justified when most of SF composition was done in software. The actual buffer locking is now ensured by gralloc. We could have handled screenshots in a similar way to a regular composition, but it could have caused glitches on screen, essentially, taking a screenshot could cause to skip a frame.

| | | | | | | | | | | | | | | | | | | | | | | | | | | when we validate the surface there, most errors are in fact allowed because it is legal to cancel a buffer after a surface has been destroyed (for instance). in that case make sure to not log error messages as they are very confusing.

* | | Fix remote GraphicBuffer allocation in SurfaceFlinger.Jamie Gennis2011-01-133-32/+123
|/ / | | | | | | | | | | | | | | | | | | | | 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 makes the camera HAL interface take an ANativeWindow interface from which all the camera preview buffers will be allocated. The framework code running in application processes now passes a Surface object rather than an ISurface to the camera server via Binder when setting the preview surface. The camera server then forwards that Surface object (which implements the ANativeWindow interface) to the camera HAL, which uses it to communicate with SurfaceFlinger to allocate the camera preview buffers.

* fix [2873058] Surface::dequeueBuffer blocks on last buffer, i.e. cannot ↵Mathias Agopian2010-07-271-30/+0
| | | | | | | | | | | | | | | | | | | | | dequeue all allocated buffers at once. this situation happened when the last buffer needed to be resized (or allocated, the first time). the assumption was that the buffer was in use by SF itself as the current buffer (obviously, this assumption made no sense when the buffer had never been allocated, btw). the system would wait until some other buffer became the "front" buffer. we fix this problem by entirely removing the requirement that the buffer being resized cannot be the front buffer. instead, we just allocate a new buffer and replace the front buffer by the new one. the downside is that this uses more memory (an extra buffer) for a brief amount of time while the old buffer is being reallocated and before it has actually been replaced.

| | | | | | | | | | | | This change adds a process-global cache of previously deserialized Surface objects so that if a Surface object wrapping the same ISurface gets received again the same Surface can be used. This is important because the 'tail' pointer in the SharedBufferClient is stored only on the client side, and needs to be the same for all the Surface objects wrapping an ISurface instance.
