Comment:
I don't see how #7285 is related. AFAICT it's about problems in the chain
of media nodes involved and issues in the media kit. The other two tickets
may or may not be related. They could as well just be caused by latencies
not being guessed/computed generously enough. Without analyzing the
scheduling behavior that's impossible to say.
@ttcoder: You found the right lock.h/cpp. If you're referring to the
priority inheritance approach, there are a few things that need to be
modified: In the Thread structure the contended locks the thread holds
need to be tracked and accordingly the lock structures need to be
adjusted. Obviously the locking functions themselves need to be modified.
Moreover changes in the schedulers are needed as well. I haven't really
thought about, whether another priority field is needed in the Thread
structure or anything else.
I don't want to discourage you working on that, but please note that
there's no documentation (other than what you find in the sources) how
things work together and I don't really have time and motivation for
introductory explanations (I suspect the same holds for others). If you
have questions about particulars, feel free to ask.
