faluco fa351cd285 Rename functions that contain the unsafe word to nolock. 
The term "unsafe" does not clearly state that the function is not locking the shared date and it sounds "dangerous", so use a more explicit term.

data structure instead.

Andre Puschmann c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t 
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

Andre Puschmann c1ad867824 epoll_helper: use std::atomic to protect exit called from different thread 2021-05-26 14:25:38 +02:00
Andre Puschmann f1e6a975de thread_pool: fix concurrent access of state variable 
the thread workers need access to their current state to exit properly
when they are set to state STOP. However, since the state is kept in
a std::vector for all workers, it seems more appropiate to add a per-thread
running variable rather then mutexing the entire vector.

Francisco f2a56c9139 simplification of multiqueue design. 
- the consumer does multi-staged waiting:
  1. spins first across all queues in a RR fashion
  2. each queue access is done with a try_lock.
  3. if the try_lock fails, it increases the number of spins needed
  2. if no queue had data, the consumer sleeps for 100 usec.
- no differentiation between queues, in terms of notification features

number.

Francisco d947e259c9 stack optimization - optimization of the multiqueue 
avoid notifying the consumer side of the multiqueue of a new pushed object, if the
multiqueue already knows that the queue is not empty.

Francisco d574afcd33 cleanup of multiqueue unused methods, and made queue_handle move semantics correct 2021-05-10 15:27:21 +01:00
Francisco ef9d1b8c13 stack optimization - reduction of contention in multiqueue class 
With the new design, each queue created in the multiqueue object has its own mutex.
Pushing tasks to separate queues will, therefore, not cause contention.
There will be, however, still contention between the popping thread and the pushing threads.
