Ue monitoring stats
- one commit to add UE mac stats similar to gNB one and remove a partial
implementation at phy level of some counters
- second commit only rename the two UE persisted HARQ tyepdef names for DL
and for UL (one was saying "UE" but not the direction and the second the
direction but not "UE")
The asserts might be used to intentionally stop the running process.
Further, it might be an annoyance if it happen unintentionally. Just
print an error message instead, and return to FlexRIC that nothing is to
be sent.
The CI pipeline RAN-NSA-B200-Module-LTEBOX-Container uses the same core
network (ltebox) as the pipelines RAN-LTE-{TDD,FDD}-LTEBOX-Container,
triggered through the same XML files. However, the core networks are on
different hosts, configured through (Jenkins) pipeline configuration. A
future MR will move the entire core network configuration into the XML
files [1]. To facilitate this, create separate XML files for the NSA
pipeline.
[1] The advantage is that it will be easier to reason with only the XML
files what is going to be run where and how.
Fix a small bug with total_res in gNB PUSCH symbol processing
Replaced total_res with res_per_task when deciding whether to start a threadpool
task or not. This does not have big impact on the software as the
nr_pusch_symbol_processing will recheck ul_valid_re_per_slot anyway but it may
reduce the number of thread pool tasks created.
- identification of each parameter in fh_init and fh_config structs
- identification of unused parameters in xran library
- identification of parameters used for CAT A O-RU
=> CAT B not supported in this release
- pass parameter directly instead of indirectly via class
- harmonize to svr_id to harmonize parameter with parameters in the next
commit (and towards a future harmonization of directly taking node
names instead of "IDs")
The queue for finished jobs of PUSCH channel estimation is only used inside
nr_pusch_channel_estimation(). Since initialization is fast, it can be
declared on the stack in the function where it is used.
This commit enables the optional use of Tracy for profiling NR UE & gNB.
See https://github.com/wolfpld/tracy/releases/tag/v0.11.1 for details.
How to compile:
use -DTRACY_ENABLE=ON to enable instrumentation and sampling
For gNB currently only sampling is implemented.
How to collect data:
- Windows hosts: tracy-profiler.exe in link above
- Linux hosts: Compile tracy-profiler from source
Enabling collection from docker:
- open port 8086
- to collect cpu data
--privileged
--mount "type=bind,source=/sys/kernel/debug,target=/sys/kernel/debug,readonly"
--user 0:0
--pid=host
How to add instrumentation:
- See examples in this commit or manual in the link above.
Fix error reported by the T2 card when running nr_dlsim with 4 DL layers.
Error can be reproduced by running:
./nr_dlsim -n100 -s30 -e25 -b273 -R273 -x4 -z4 -y4 -P --ldpc_offload.dpdk_dev 41:00.0 -c
So far we set NR_LDPC_MAX_NUM_CB to 72, which is sufficient for max 2 DL layers.
Set max possible number of LDPC segments based on the max number of layers
and max number of DLSCH segments (currently it is 144).
