Andre Puschmann f647343f18 rlc_am: fix poll bit during header reconstruction
this makes sure that the reconstructed RLC AM header
has the poll bit set when any of its segments had it set.

this triggered a bug in RLC AM because the Status PDU
isn't transmitted for a RLC PDU that was segmented and
only the first segment had the P flag set.

gracid f67a152a2a Remove unnecessary Lime calibration step from Soapy implementation
When using srsLTE with Lime devices, calibration was performed before any configuration steps have happened, thus making calibration values invalid. Removing Lime specific calibration step from rf_soapy_imp makes so that devices will be automatically calibrated by SoapyLMS on rf_soapy_start_stream call.

Tested and working with srsENB using LimeSDR-USB v1.4 and LimeSDR-Mini v1.2 boards.

install all individual libraries

Jan Remeš 8c7b7cc55a libsrslte_rf: add library version
This patch adds version string to the 'libsrslte_rf' library.
This results in the library being built as
    libsrslte_rf.so.20.04.2
with the following symbolic links
    libsrslte_rf.so.0 -> libsrslte_rf.so.20.04.2
    libsrslte_rf.so -> libsrslte_rf.so.0

The SRSLTE_SOVERSION variable should be increased with each backwards
incompatible change of the library.

Andre Puschmann d48bc8837e pdu: refactor MAC PDU class
this patch refactors the MAC PDU class, the main changes are:

* add to_string() method to pretty print PDU and subheaders
  This allows to have a single log entry per MAC PDU with all its
  contents.
  It removes the C-style fprint() method

* Simplity payload vs. w_payload_ce
  Before we've used payload when reading the PDU and w_payload_ce
  as a buffer when writing. In all getters we needed to differentiate
  between both. Now payload points to w_payload_ce initially and is
  only updated when parsing a new PDU.

* add various helpers, e.g. to get subheader index, update a BSR, ..

* fix PDU test to use new to_string() method

Andre Puschmann 3f02e56a1e uhd: do not stop rx_stream when setting rx_rate for the B210
with the B210 and 2 RF ports, i.e. MIMO mode, we have stopped the
Rx stream after changing the rx_samp_rate but didn't start it again.

Either the issue doesn't exist in SISO mode or we never saw it but for MIMO
it can be reproduced easily with rate changes during streaming, i.e.:

and extends the API accordingly.

Note: According to the original UHD commit in

it looks like the Rx timestamps are disabled by default

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism

Andre Puschmann f6d3467884 ringbuffer: fix timeout calculation for timed read
with ZMQ RF, we've seen the radio returning -1 and traced
the issue down to the ringbuffer.
in fact, pthread_cond_timedwait() returned 22 (EINVAL) indicating
a wrong timeout value. The issue was likely an overflow
in the timespec parameter. This patch checks for the return
value of pthread_cond_timedwait() and also calculates the
nanosecond wrap around for the timespec

Andre Puschmann aed38a6028 rf_zmq: increase default ZMQ timeout to 2s
amarisoft flags an RF error and exits after not receiving samples
for the radio. Running with ZMQ in the RFCI, the UE sometimes needs more
time to start up due to slow processing and no fftw wisdom file and
then Amarisoft eNB times out. This gives the whole process a little
bit more time. Should we still find it too short we may increase
it further.

Andre Puschmann 95f5093432 rlc_am: hold lock while handling new PDUs
This lock was removed in 1cbf7eac because it was considered unneeded.
However, as can be seen in issue #1503, we need to protect the access
to rx_window, for example.

Issue #1503 shows a stack trace where a PHY worker generates a status PDU.
While holding the mutex to access rx_window, the stack thread on the
other hand, happily accesses the rx_window member without acquiring
the lock. This commit protects all handle_*() functions in write_pdu().

This reverts commit 1cbf7eac04.

Andre Puschmann 6f5da19312 pdcp: similar to tx, also reduce log for Rx
instead of logging PDU received from below, and SDU that is forwarded
to above, only log the PDU in rx in info mode.

The next layer will do the same and log the PDU received (which is the SDU coming from here)
so there is now loss of information in the logs.
