Francisco b06f16891d use of a single array-based pool of RLC AM PDU segments to build data PDUs, while
avoiding any allocations.
Each segment stores its own PDCP SN and RLC SN and has two pointers,
one for the next segment of the same RLC PDU, and another for the next segment
of the same PDCP PDU.

Andre Puschmann 44baea6666 mac_nr: add UL HARQ
this patch adds a basic UL HARQ entity for NR.

The patch also updates some interfaces between MAC/RA/HARQ,
i.e. get_temp_crnti().

It also adds a Msg3 unit test.

faluco a2f6e13138 Add a tag to the string memory pool in fmt to discriminate between pool vs heap allocated buffers. Heap allocated buffers are used as a fallback mechanism when the buffer runs out of space. 2021-04-13 17:36:39 +02:00
faluco 0465f6badd Implement a pool in FMT to avoid allocating heap memory when passing a char* to the backend, usually when formatting a %s argument.
Previously since a char* can have any length, this was managed by FMT by converting it into a std::string.
Now we store it into a configurable size node that can store a fixed size string, otherwise it falls back to std::string.

Andre Puschmann 48537f3fe7 pdcp,rlc: increase number of PDCP SDUs for notification from RLC
the current value of 256 limits the number of PDCP SDUs that can be
notified from RLC. The limit is quickly hit when too many SDUs
are in flight. This can cause unwanted log entries and weird PDCP
behaviour.

the patch increases the value to 1024, which still can be too few if
many smaller SDUs are traveling.

The patch also set the log level to warning to quicker spot
misconfigs in logs.

Fixes #2616
