Re: [Discuss-gnuradio] cmake warning with -DENABLE_PERFORMANCE_COUNTERS-On (gr-ieee80211)

[sumit kumar]

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 

CMake Warning:

  Manually-specified variables were not used by the project:

    ENABLE_PERFORMANCE_COUNTERS

In order to do timing analysis of individual blocks of gr-ieee80211, I am following the documentation at

https://gnuradio.org/doc/doxygen/page_perf_counters.html

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