* added native_window_set_buffer_count()Mathias Agopian2010-05-211-0/+1
| | | | | | | this method can be used to change the number of buffers associated to a native window. the default is two. Change-Id: I608b959e6b29d77f95edb23c31dc9b099a758f2f
* fix the threading issue for setBuffercount()Mathias Agopian2010-05-201-14/+29
| | | | | | | | 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"
* fix some bugs in SharedBufferStack::resizeMathias Agopian2010-05-171-4/+5
| | | | | | added buffers should now be labeled properly. Change-Id: I28aa753fbe89ab89134e7753575319478934c7fa
* Fix issue 2553359: Pandora does not work well with Passion deskdock / Cardock.Eric Laurent2010-05-171-11/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is due to a too big difference between the buffer size used at the hardware interface and at the A2DP interface. When no resampling occurs we don't notice problems but the timing is very tight. As soon as resampling is activated, the AudioTrack underruns. This is because the AudioTrack buffers are not resized when moving the AudioTrack from hardware to A2DP output. The AudioTrack buffers are calculated based on a hardware output buffer size of 3072 bytes. Which is much less than the A2DP output buffer size (10240). The solution consists in creating new tracks with new buffers in AudioFlinger when the A2DP output is opened instead of just transfering active tracks from hardware output mixer thread to the new A2DP output mixer thread. To avoid synchronization issues between mixer threads and client processes, this is done by invalidating tracks by setting a flag in their control block and having AudioTrack release the handle on this track (IAudioTrack) and create a new IAudioTrack when this flag is detected next time obtainBuffer() or start() is executed. AudioFlinger modifications: - invalidate the tracks when setStreamOutput() is called - make sure that notifications of output opening/closing and change of stream type to output mapping are sent synchronously to client process. This is necessary so that AudioSystem has the new stream to output mapping when the AudioTrack detects the invalidate flag in the client process. Previously their were sent when the corresponding thread loop was executed. AudioTrack modifications: - move frame count calculation and verification from set() to createTrack() so that is is updated every time a new IAudioTrack is created. - detect track invalidate flag in obtainBuffer() and start() and create a new IAudioTrack. AudioTrackShared modifications - group all flags (out, flowControlFlag, forceReady...) into a single bit filed to save space. Change-Id: I9ac26b6192230627d35084e1449640caaf7d56ee
* AudioFlinger: rename variables to clarify reference to track channel count ↵Eric Laurent2010-05-141-1/+1
| | | | | | | | | | | or channel mask Some variables and structure members should be renamed to reflect the fact that they contain the number of channels in a track (channel count) or the actual channels used by a track (channel mask). Especially member "channels" of track control block (struct audio_track_cblk_t) is actually the number of channels (channels count). Change-Id: I220c8dede9fc00c8a5693389e790073b6ed307b8

* cleanup. waitForCondition() now uses polymorphsim instead of templtesMathias Agopian2010-04-281-49/+10
| | | | | | | | | 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. Change-Id: I2595d850832628954b900ab8bb1796c863447bc7
* fix a race condition in undoDequeue(), where 'tail' could be computed ↵Mathias Agopian2010-04-281-2/+2
| | | | | | | | | | | | | | | 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().

* fix [2170319] gmail bulk operation checkbox latency on passionMathias Agopian2009-10-072-48/+1
| | | | | | | | | | | | | | | This also fixes [2152536] ANR in browser When SF is enqueuing buffers faster than SF dequeues them. The update flag in SF is not counted and under some situations SF will only dequeue the first buffer. The state at this point is not technically corrupted, it's valid, but just delayed by one buffer. In the case of the Browser ANR, because the last enqueued buffer was delayed the resizing of the current buffer couldn't happen. The system would always fall back onto its feet if anything -else- in tried to draw, because the "late" buffer would be picked up then.
* fix [2152536] ANR in browserMathias Agopian2009-10-061-7/+13
| | | | | | | | | | | | | | | | A window is created and the browser is about to render into it the very first time, at that point it does an IPC to SF to request a new buffer. Meanwhile, the window manager removes that window from the list and the shared memory block it uses is marked as invalid. However, at that point, another window is created and is given the same index (that just go freed), but a different identity and resets the "invalid" bit in the shared block. When we go back to the buffer allocation code, we're stuck because the surface we're allocating for is gone and we don't detect it's invalid because the invalid bit has been reset. It is not sufficient to check for the invalid bit, I should also check that identities match.

* fix [2167050] glTexImage2D code path buggy in SurfaceFlingerMathias Agopian2009-10-062-127/+1
| | | | | | | | | | | | | | When EGLImage extension is not available, SurfaceFlinger will fallback to using glTexImage2D and glTexSubImage2D instead, which requires 50% more memory and an extra copy. However this code path has never been exercised and had some bugs which this patch fix. Mainly the scale factor wasn't computed right when falling back on glDrawElements. We also fallback to this mode of operation if a buffer doesn't have the adequate usage bits for EGLImage usage. This changes only code that is currently not executed. Some refactoring was needed to keep the change clean. This doesn't change anything functionaly.
* Attempt to fix [2152536] ANR in browserMathias Agopian2009-10-021-7/+9
| | | | | | | | | | | The ANR is caused by SurfaceFlinger waiting for buffers of a removed surface to become availlable. When it is removed from the current list, a Surface is marked as NO_INIT, which causes SF to return immediately in the above case. For some reason, the surface here wasn't marked as NO_INIT. This change makes the code more robust by always (irregadless or errors) setting the NO_INIT status in all code paths where a surface is removed from the list. Additionaly added more information in the logs, should this happen again.

* fix [2068105] implement queueBuffer/lockBuffer/dequeueBuffer properlyMathias Agopian2009-09-074-156/+331
| | | | | | | | | | | | | | | Rewrote SurfaceFlinger's buffer management from the ground-up. The design now support an arbitrary number of buffers per surface, however the current implementation is limited to four. Currently only 2 buffers are used in practice. The main new feature is to be able to dequeue all buffers at once (very important when there are only two). A client can dequeue all buffers until there are none available, it can lock all buffers except the last one that is used for composition. The client will block then, until a new buffer is enqueued. The current implementation requires that buffers are locked in the same order they are dequeued and enqueued in the same order they are locked. Only one buffer can be locked at a time. eg. Allowed sequence: DQ, DQ, LOCK, Q, LOCK, Q eg. Forbidden sequence: DQ, DQ, LOCK, LOCK, Q, Q
