* | Change the framework to use the new camera preview path.Jamie Gennis2010-08-232-5/+10
|/ | | | | | | | | | | | 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.

* Re-use existing Surface objects when reading them from parcels.Jamie Gennis2010-07-161-7/+28
| | | | | | | | | | | | 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. This solves the problem by making there only be one Surface object wrapping an ISurface per process. Change-Id: I4bf0b8787885c56277622fca053022d2bb638902
* Introduce official public NativeWindow type.Dianne Hackborn2010-06-301-18/+18
| | | | | | | Not yet hooked up to anything in the NDK, but requires renaming the existing android_native_window_t type everywhere. Change-Id: Iffee6ea39c93b8b34e20fb69e4d2c7c837e5ea2e
* allow re-targetting of surfacesMathias Agopian2010-06-082-15/+44
| | | | | | | | | Surfaces can now be parcelized and sent to remote processes. When a surface crosses a process boundary, it looses its connection with the current process and gets attached to the new one. Change-Id: I39c7b055bcd3ea1162ef2718d3d4b866bf7c81c0

* optimize Surface.readFromParcel()Mathias Agopian2010-06-041-8/+13
| | | | | | | | | | | | this is called for each relayout() and used to create a full Surface (cpp) which in turn did some heavy work (including an IPC with surfaceflinger), most of the time to destroy it immediatelly when the returned surface (the one in the parcel) was the same. we now more intelligentely read from the parcel and construct the new object only if needed.

* more clean-up of Surfaceflinger's client managementMathias Agopian2010-05-272-238/+170
| | | | | | | | | | | | SurfaceComposerClient now only exist on the WindowManager side, the client side uses the new SurfaceClient class, which only exposes what a client needs. also instead of keeping mappings from IBinder to SurfaceComposerClients we have a SurfaceClient per Surface (referring to the same IBinder), this is made possible by the fact that SurfaceClient is very light.

* added native_window_set_buffer_count()Mathias Agopian2010-05-212-1/+11

* fix the threading issue for setBuffercount()Mathias Agopian2010-05-204-57/+79
| | | | | | | | this change introduces R/W locks in the right places. on the server-side, it guarantees that setBufferCount() is synchronized with "retire" and "resize". on the client-side, it guarantees that setBufferCount() is synchronized with "dequeue", "lockbuffer" and "queue"

* | Refactor some code in surfaceflinger in preparation of upcoming changesMathias Agopian2010-05-121-0/+1

This is used indirectly by Layer and directly by LayerBuffer the new BufferManager class handles the set of buffers used for a Layer (Surface), it abstracts how many buffer there is as well as the use of EGLimage vs. regular texture ops (glTexImage2D).

* | cleanup. waitForCondition() now uses polymorphsim instead of templtesMathias Agopian2010-04-282-21/+51
| | | | | | | | | | | | | | | | | | the reason for the above change is that waitForCondition() had become large over time, mainly to handle error cases, using inlines to evaluate the condition doesn't buys us much anymore while it increases code size.

* | fix a race condition in undoDequeue(), where 'tail' could be computed ↵Mathias Agopian2010-04-281-24/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | incorrectly. in the undoDequeue() case, 'tail' was recalculated from 'available' and 'head' however there was a race between this and retireAndLock(), which could cause 'tail' to be recalculated wrongly. the interesting thing though is that retireAndLock() shouldn't have any impact on the value of 'tail', which is client-side only attribute. we fix the race by saving the value of 'tail' before dequeue() and restore it in the case of undoDequeue(), since we know it doesn't depend on retireAndLock().

* libutils Condition are now PRIVATE by defaultMathias Agopian2010-03-191-1/+1
| | | | | | | | | | | Condition must be initialized with SHARED for the old behavior, where they can be used accross processes. Updated the two places android that require SHARED conditions.
