Minimalist gnb tracer to trace (for the moment) rxdataF when some
decoding for PUCCH or PUSCH has been done.
Important: T_BUFFER_MAX and T_CACHE_SIZE have been changed. T_BUFFER_MAX
is twice as big as before. T_CACHE_SIZE has been devided by two. Globally,
the memory usage of the T tracer is the same, but since we divided by two
the number of buffers in the cache, we may hit some realtime problems if
all the buffers are busy at some point. The simple solution would be to
use 8192*2 for T_CACHE_SIZE as it was, but then we double the memory usage
of the T tracer. This, or another solution, to be defined.
There was a problem with several UEs in the wireshark log. It seems that
wireshark needs the UE id otherwise it gets confused and sees retransmissions
where it's just another UE connecting and doing the same as a previous
UE.
Let's put kind of a UE id. Each RNTI seen by macpdu2wireshark gets an UE id
assigned the first time it's seen in a trace.
This is a bit hackish but seems to be fine.
We could have added UE_id in all the traces, that is change the T() calls
in the softmodem. It was less work to do it as it is, ie. only touch
macpdu2wireshark.c.
The RAR uses the same UE id all the time, may be a problem. To be refined
if needed.
The T tracer macpdu2wireshark has been modified to handle the new traces.
The usage is the same as for LTE.
In NR the RACH is logged as an LTE RACH. Maybe we'll change that in the
future. Looking at the source code of wireshark, I could not find any
way to report NR RACH. Maybe they forgot it. Or I did not search correctly...

This commit introduces an alternative RLC implementation
based on 36.322 version 8. AM and UM done, TM not done.
See openair2/LAYER2/rlc_v2/TODO for missing parts.
To be used when you send data to another host.
On the other host, to avoid ICMP traffic about the port
not being open, do:
./nc -l -u -p 9999 > /dev/null
You need to restart this command each time you run macpdu2wireshark.
You can use any other program that will accept UDP packets on the
port 9999 (default port of macpdu2wireshark, change if you use another
port of course).
Not much major changes. In openair1/PHY/LTE_UE_TRANSPORT/dci_tools_ue.c,
in the function generate_ue_dlsch_params_from_dci,
'harq_pid' was removed and dci_info_extarcted.harq_pid is now used for
all cases.
The ue T tracer only deals with PHY signals (no MAC, RLC, PDCP, RRC).
A new option -live has been added to run live (ie. like the 'enb' tracer)
and options -live-ip and -live-port to select IP/port of the machine running
the eNodeB.
Some new options to control MIB and SIBs recording have been added.
Some global variables have been removed.
If you run 'make' in common/utils/T/tracer
just after a clone of the repository then the
compilation will fail because the file ../T_IDs.h
was not generated.
Let's add a simple dependency to fix this.
The tracer macpdu2wireshark can send MIBs to wireshark.
This can be disabled by passing the new -no-mib option.
openair1/SCHED/phy_procedures_lte_eNb.c has been modified
to have a new T trace with the MIB.
This commit removes the warning:
make[4]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule.
Basically, inside a Makefile we should use $(MAKE) instead of make.
Make it compatible with 'template' gtwave files as found in openair's
repository.
The type VCD_NAME was added to the VCD IDs in T_messages.txt.
The database processing code was adapted to use it.
The tracer to_vcd was adapted to use it and render the produced vcd
output compatible with the 'template' gtkwave files.
When running to_vcd, do not forget to pass -vcd to use this feature.
This tracer allows the connection of several tracers to one tracee.
To use the multi tracer:
- run the tracee as usual, eg. ./lte-softmodem -O xxxx.conf --T_stdout 0
- run the multi tracer: ./multi -d ../T_messages.txt
- connect other tracers to the multi tracer:
- ./enb -d ../T_messages.txt -p 2022
- ./textlog -d ../T_messages.txt -p 2022
- etc.
By default the multi tracer connects to the tracee to the port 2021,
as for any other tracer.
Then it accepts connections from other tracers on the port 2022.
This can be changed with parameters on the command line.
The tracee and the other tracers can be stopped/started at any time.
Whenever the value T_BUFFER_MAX changes, the tracers had to
be recompiled. The only reason why it was needed is because we
used some fixed size buffers to read events. This commit removes
this restriction.
Also, with the basic simulator, this value T_BUFFER_MAX now comes
with an #ifdef which would have required some special hackish-level
tricks in the tracers, which is not good.
Let's just allocate memory when needed.
