Webplay_ringbuffer(ringbuffer, channels=None, start=0, allow_belated=True) Send a RingBuffer to the callback to be played back. By default, the number of channels is obtained from the ring buffer’s elementsize. stats Get over-/underflow statistics from an inactive stream. To get statistics from an activestream, use fetch_and_reset_stats(). WebThe first few patches fix other broken RT features that were discovered while debugging hotplug. Patch 7 is a rework of how RT handles taking down a CPU. There were several corner cases that the original approach failed on, and this rework seems to cover them now. Patch 8 and 9 revert the rework that was done on workqueue for RT.
