Re: [Discuss-gnuradio] cmake warning with -DENABLE_PERFORMANCE

So, the performance counters need to be enabled in your GNU Radio preferences; I don't think editing the configuration input template helps, unless you build & reinstall (don't do that). Instead, run `gnuradio-config-info --prefs` first and check whether PerfCounters are enabled.

To query these counters, you can

use the gr::block::pc_bla_foo() methods of every block, or

use ControlPort at run time, for example using the gr-ctrlport-monitor, which you can add to a flowgraph elegantly from GRC. This, however, requires both an enabled controlport in CMake as well as a working and found Thrift installation at CMake time – check whether the CMake output contain

Ok I understood. Now I have a following question.

I did a grep in the build directory

grep -r 'work_time_total' .

And I found that indeed its there as said on https://gnuradio.org/doc/doxygen/page_perf_counters.html

It seems a lot of task is already been done ! :)

Then I opened gnuradio-runtime.conf.in and did the following (as mentioned in the documentation)

[PerfCounters]

on = True

export = True

#clock = thread

clock = monotonic

Now I run my application , for example wifi_rx.py

Where do I see the timings ?

I opened the ieee802_11_swig.py, and I see def pc_work_time_total(self) is there for all the blocks, but how to use them :-/

Can you give a use case, for example :

In line 1953 of ieee802_11_swig.py, we have

class frame_equalizer_sptr(object):

and inside this calss we have the function :

def pc_work_time_total(self):

"""pc_work_time_total(frame_equalizer_sptr self) -> float"""

return _ieee802_11_swig.frame_equalizer_sptr_pc_work_time_total(self)

Now what should I do to see total time consumed by frame_equalizer and where do I expect the output.

Hi Sumit,

Does only GNU Radio need to be built with the flag -DENABLE_PERFORMANCE_COUNTERS or the OOT projects too ?

exactly, only GNU Radio needs to be built with that flag – functionally, it's something that is done in the scheduler, not in the blocks the scheduler runs.
Best regards,

Marcus

Hi,

I have to do timing analysis of individual blocks of gr-ieee80211

I have built my gnuradio with the following

~/rfnoc/src/gnuradio/build$ cmake -DCMAKE_INSTALL_PREFIX=/home/john/rfnoc -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_PERFORMANCE_COUNTERS=On -Werror ../

build was successful.

And again I built gr-ieee80211 with following

~/rfnoc/src/gr-ieee-80211/build$ cmake -DCMAKE_INSTALL_PREFIX=/home/john/rfnoc -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_PERFORMANCE_COUNTERS=On -Werror ../

However I get a warning that
