* Shave another 10us off of hwuitaskJohn Reck2015-03-241-2/+4
| | | | | | | | | | | | | pthread_cond_signal does not need the mutex to be held to signal. This results in the thread waking up trying to grab the lock, failing, the signaling thread to wake up, release the lock, immediately get preempted for the signaled thread which can now proceed. Release the mutex before signaling to avoid the ping-pong scheduling issue, which shaves another 10us off of this Change-Id: Ie6bccca031ba6528f357eae8352b74626a6318c7
* Shave 10us off of hwuitaskJohn Reck2015-03-241-2/+5
| | | | | | | | | | | This prevents an issue where if the signal schedules hwuiTask it will immediately block and go back to sleep due to mLock still being held. This costs 10us in thread scheduling ping-ponging bouncing between hwuiTask and RenderThread Change-Id: I47595c1bf5736576483a6aa7aada0b1be1e04268

| | * Fix ANR caused by hwuiTask threadSangkyu Lee2015-01-122-10/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If hwuiTask thread is exited while HWUI renders something, some tasks can remain unfinished forever. This can make ANR problem if RenderThread waits this kind of tasks. According to the current implementation, hwuiTask threads are exited when HWUI receives trimMemory() callback with level >= 20 and some applications such as SystemUI can receive trimMemory() with level >= 20 even though they renders something yet. (For instance, when RecentsActivity in SystemUI is finished, HWUI receives trimMemory() callback with level >= 20 but SystemUI should still render the status bar and navigation bar.) This patch prevents the tasks from remaining unfinished and make the tasks executed immediately if they cannot be added to their TaskProcessors. Change-Id: I5bd26439aa5f183b1a7c1ce466362e27554b4d16

* Add TaskManager APIRomain Guy2013-03-125-1/+354
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This API can be used to run arbitrary tasks on a pool of worker threads. The number of threads is calculated based on the number of CPU cores available. The API is made of 3 classes: TaskManager Creates and manages the worker threads. Task Describes the work to be done and the type of the output. A task contains a future used to wait for the worker thread to be done computing the result of the task. TaskProcessor The processor dispatches tasks to the TaskManager and is responsible for performing the computation required by each task. A processor will only be asked to process tasks sent to the manager through the processor. A typical use case: class MyTask: Task<MyType> class MyProcessor: TaskProcessor<MyType> TaskManager m = new TaskManager(); MyProcessor p = new MyProcessor(m); MyTask t = new MyTask(); p.add(t); // Waits until the result is available MyType result = t->getResult(); Change-Id: I1fe845ba4c49bb0e1b0627ab147f9a861c8e0749
