Andre Puschmann c1ad867824 epoll_helper: use std::atomic to protect exit called from different thread 2021-05-26 14:25:38 +02:00

yagoda 8d2568ed2c small fix for console print for cyclic prefix 2021-05-26 11:11:44 +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

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.

Andre Puschmann 833ddc3229 build: fix linking failure on RPi 32bit 
this fixes a linking problem with RPi 3 (and probably others) running
with Raspbian (new Raspberry Pi OS) that can't use the inline
atomic functions but instead require linking against the lib -latomic.

The CMake code is based on SoapyRTLSdr file (licensed under MIT)

Andre Puschmann 9950278a12 nr,mac_sch_pdu,mux: fix packing of MAC subPDUs with 16bit L field

The patch determines the correct size before passing the opportunity to RLC.

It also improves logging in error case by using the MAC logger instead of
stderr/stdout when error occurs.
