A new logger is there: the "ticked TTI logger".
Similar to TTI logger (used by the PUCCH1 energy plot)
but takes another input, the "tick" (think subframe)
and a default value for when no event is triggered between
two ticks.
This is used for the UL and DL MCS plots in enb.c (next commit).
When the user clicks on "next UE" or "prev UE" we change the
filters of loggers.
At the same time, the main thread of enb.c processes events
received from the soft-modem and uses the filters, some of them
maybe in the process of being changed.
Changing the filters is not atomic and has to be protected.
Just below the logo you see the current UE, eg. [UE 0],
and near that you have two "buttons" [prev UE] and [next UE].
You click with left button of mouse on those and the various
plots that depend on the UE are now done for the new UE (say UE 1
instead of UE 0 if you click on [next UE]).
The plots are not cleared when you switch.
Let's say it's a feature.
This tracer takes the traces ENB_MAC_UE_DL_PDU_WITH_DATA
and ENB_MAC_UE_UL_PDU_WITH_DATA from a trace file
(as generated by the "record" tracer) and sends them
in UDP packets correctly formatted for wireshark to
dissect them.
One unresolved problem I face with my version of
wireshark (1.10.6) is that I don't get the frame number,
only subframe. See in the code to change the behavior
if you use a more recent version of wireshark.
You need to properly configure wireshark for it to work.
See $OPENAIR_DIR/openair2/UTIL/OPT/README.txt.
XY_LOOP_MODE: replace old points with new ones, using the maximum size
of the view
XY_FORCE_MODE: append_forced sets those and only those points
and we crash if we pass too much points
this is like timeview but the plotting is done at frame/subframe
resolution of a given reference clock signal, let's say.
The realtime information of the events is not used. It's all
logical.
It will be used to log harq processes for the moment.
