Andre Puschmann f992350d2d rlc_um_nr_pdu_test: add testcases for 12bit SN length packing/unpacking 2021-03-25 08:06:49 +01:00
AlaiaL 1cc2cc4e7f Fixed typo 2021-03-24 12:01:12 +01:00
AlaiaL fd3c2b855e - Renamed log to logger. 
- Added a log entry in the metrics when skipping a measurement due to
time constrains
 2021-03-24 12:01:12 +01:00
AlaiaL bbaebd1274 Added a warning in the log when the cpu metrics are not registered due 
to the number cpu cores is greater than supported.
 2021-03-24 12:01:12 +01:00
AlaiaL c9d1c77e8c - Deleted the magic number of maximum supported cores, now it is a 
constexpr.
- When the system has more cores that the maximum supported, the cpu
metrics will not be registered.
 2021-03-24 12:01:12 +01:00
AlaiaL 6cd9bba641 Added the cpu metrics to the system metrics. 2021-03-24 12:01:12 +01:00
Xavier Arteaga 5bdf2c93b3 Initial NR PDSCH CSI-RS RE skip and other changes 2021-03-24 09:06:26 +01:00
Pedro Alvarez 5bc55ec48c Changed discard_if to appyly_if in circular_buffer.h. 
This was done so it would work when circular buffer holds other things
that are not unique_pointers. Queue and pop_func had to be made public
to be able to call the pop_func when an SDU is discarded.

Andre Puschmann 1b1cfa40c9 rlc_am_lte: add some more sanity checks around retx of PDUs 
this patch doesn't change any functionality but adds a bit
of further error checking around the handling of status PDUs
and the retx of PDUs

faluco e8395c7474 - Implement a pool to store dyn arg store objects in srslog to avoid allocations when passing arguments to the backend. 
- Use string views inside the log formatters to avoid allocations.
- Avoid a std::string when using fmt::vsprintf, instead favour fmt::vprintf.

Andre Puschmann 47654af717 pdcp_entity_lte: fix printf formatter for size_t 
we've seen a heap-buffer overflow in fmt because printf wasn't using
the right formtter for size_t, which should be %zu

this patch fixes it for the PDCP LTE entity but we might have it elsewhere too

Andre Puschmann 2cfc657fbb rlc_am_lte: refactor logging when PDCP SDUs are enqueued 
the patch refactor the logging when a new PDCP SDU is enqueued for
transmission at RLC.

If the SN is already present, only a warning is logged. From the RLC
perspective operation continues and the SDU will be transmitted.

The patch also changes the order of logs. When the SN cannot be inserted
inside the queue of undelivered SDUs, only one message is logged.

Andre Puschmann 20cbc48f90 rlc_am_lte: refactor PDCP/RLC interface to use fix sized data structure 
this patch replaces the std::vector type used in the interface between
PDCP and RLC to signal delivery status between both layers. The new
data type is a configurable but fixed-size vector.
The RLC AM doesn't need to dynamically allocate the vector for every SN but
uses the tx_window for storage.
