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.
This tracer extracts the content of a buffer field of an event
that was previously saved using the tracer 'record'.
For example, to extract the channel estimation done in
frame 924 and subframe 2 as saved in the file input_record.raw
and to store it in the file output.raw, do:
./extract -d ../T_messages.txt -o output.raw input_record.raw ENB_PHY_UL_CHANNEL_ESTIMATE chest_t -f frame 924 -f subframe 2
- UE_id 0 is for rnti 65535 (sib)
- UE_id 1 is for rnti 65534 (this is a hack)
- UE_id 2 is for rnti 2 (RA RNTI as of today's code/config)
- we start enb by displaying UE_id 3
- there was a bug: we need to lock when resetting UE ids (reset_ue_ids)
