* Remove the unused thunk codeChris Robinson2018-02-029-138/+0
|
* Remove the individual source queue and buffer locksChris Robinson2018-02-024-134/+24
| | | | | | | They're inherently protected by the mutex for their respective lists. Should those mutexes be replaced by rwlocks the individual locks should also be reinstated, but they're unlikely to be unless a lot of contention starts happening in the read-only case.
* Store an index to a given source's voiceChris Robinson2018-02-012-10/+20
| | | | For more efficient voice lookups when needed.
* Remove unused _timed methodsChris Robinson2018-02-012-123/+0
| | | | | They're not reliably implemented anyway, as some systems will just flat out fail when trying to use them.

|
* Use a semaphore to signal the event handlerChris Robinson2018-02-014-19/+9
| | | | | | | | | | | Semaphores allow for semi-persistent signals, compared to a condition variable which requires a mutex for proper detection. A semaphore can be 'post'ed after writing some data on one thread, and another thread will be able to recognize it quickly even if the post occured in between checking for data and waiting. This more correctly fixes a race condition with events since the mixer shouldn't be using mutexes, and arbitrary wake-ups just to make sure an event wasn't missed was quite inefficient.

* Don't print buffer completed events in alffplayChris Robinson2018-01-311-0/+6
|
* Add a thread to marshal events from the mixerChris Robinson2018-01-313-4/+105
| | | | | | To avoid having unknown user code running in the mixer thread that could significantly delay the mixed output, a lockless ringbuffer is used for the mixer to provide events that a secondary thread will pop off and process.

| | | | | This is now similar to buffers, being stored in groups of 64 in a vector with the ID providing the array indices.

* Use a different method for storing and looking up buffersChris Robinson2018-01-275-110/+226
| | | | | | | | | | | | | | | | | Rather than each buffer being individually allocated with a generated 'thunk' ID that's used with a uint:ptr map, buffers are allocated in arrays of 64 within a vector. Each group of 64 has an associated 64-bit mask indicating which are free to use, and the buffer ID is comprised of the two array indices which directly locate the buffer (no searching, binary or otherwise). Currently no buffers are actually deallocated after being allocated, though they are reused. So an app that creates a ton of buffers once, then deletes them all and uses only a couple from then on, will have a bit of waste, while an app that's more consistent with the number of used buffers won't be a problem. This can be improved by removing elements of the containing vector that contain all-free buffers while there are plenty of other free buffers. Also, this method can easily be applied to other resources, like sources.
