Francisco 8df6ed07c6 sched small fixes - use 0.930 instead of 0.932 for max coderate. Allow computing mcs/tbs based on max coderate directly. Other small fixes 2021-05-24 17:25:07 +02:00

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

Andre Puschmann bc3be73364 rlc_am_lte: replace simple sanitfy check with error log with expect

Andre Puschmann 21b3635ae4 rlc_am_lte: refactor retransmit_pdu() to send different SNs 
it seems that different SNs should be retransmitted depending
on the actual situation. In case of pollRetx timer expiration,
vt_s - 1 should actually be resent.

This patch prepares the function to accept different SNs but
leaves it to send vt_a by default. The RLC AM test would need
to changed as well to not fail.

Francisco d947e259c9 stack optimization - optimization of the multiqueue

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.
