Francisco Paisana 67d6a25194 Moving mac timers to stack timers (#638) 
* first step towards moving MAC timers to stack. Mac is still using its own timers. srslte::timers class can be restructured.

* moved timers out of the UE MAC

Francisco Paisana 58e2e51044 removed rlc_interfaces. The rlc_cnfg types are now part of the rrc_interface_types. Removed implicit RB initialization in the RLC. 2019-07-05 10:44:15 +02:00
Andre Puschmann acbe7fabe4 rlc: fix class member initialization 
uninitialized member detected by coverity, now converted all default
initialization to be done in class definition

Andre Puschmann e8d6236975 remove init for all RLC TM/UM/AM 
- all RLC entities are now initialized during contruction
- there is no need to check for, e.g., existance of timers, during
  runtime
- there is also no need to call re-init during resume
- timers are freed in dtor

Andre Puschmann 86232c143e expose RLC tx queue length through config struct 2019-02-01 17:11:55 +01:00
Andre Puschmann c3441046c9 simplify RLC buffer status query procedures 
- add a simple and low-overhead has_data() method to check whether
  an RLC entity has data to transmit or not
- use this method for all calls that are actually not interested
  in the amount of data to send
- use the more expensive get_buffer_state() for all cases where
  the actual size of the buffer is of importance

Andre Puschmann a6d9181881 fix RLC UM issue with very large MAC grants 2018-10-03 14:58:24 +02:00
Andre Puschmann 22b4396c39 increase default tx_queue length for RLC UM and AM 
- With the current default tx queue length (16 SDUs) the BSR reported by the UE
  is too low if the size of the SDU is relativly small (e.g. 100 B).
  This effectivly causes the eNB to only allocate a small grant
  to the UE and thus reduces the UL throughput for small SDUs.

Changes on srsENB mutexing logic to fix general race condition and deadlock issues (#229) 
* fixed some issues with the UL scheduling

* Hack to fix UL scheduler

* minor fix

* Cleaned up code and fixed issue with the update_allocation function

* fixed the console printing in the enb

* log/console fix

* fixed the log print

* added a normalization factor

* RLC: entity uses dynamic instances. Simplified stop/reset/reestablish procedure. Added non-blocking interface

* Limit decimals in metrics stdout

* Changed mutexes to rwlock in RLC/RRC/MAC/PDCP to fix race conditions when removing users

* Fix deadlock bug for MIMO

* Remove headers

* Fix missing unlock causing overflows

* Do not decrease CQI when PUCCH (this is a temporal fix, requires to reduce the maximum MCS)

* Fix mutex unlock in worker

* Configurable RLC tx buffer. Default to 512 for enodeb

* Check NULL SDU in write_sdu()

* Protect RLC objects and tx_queue from being destroyed while using it

* Remove superfluous code

* Disable SIB logging

* Fix block_queue for enb
