JACK2 code base can be instrumented (using the
"--profile Build with engine profiling" option ) to give more precise
understanding of the source of possible Xruns.
See : http://www.grame.fr/Ressources/pub/JACK2_lac2009.pdf
We cannot fix possible issues if they are not reported with some precise infos on what
happens.
I started playing with this -- and this is pretty cool. Great work!
I had been avoid this because I figured it comes with a performance overhead (like -gprof
does). Or, perhaps it only has overhead when you use it (like Sun's strace). What
overhead does compiling with --profile introduce? Why not have it enabled by default?
Suggestion/Issue: I have PDF issues with the TimingN.plot (gnuplot) files that it
outputs. They always issue the command 'set terminal pdf' and try to output a PDF
file. These create an error on my system and I have to manually delete them or change
them to something like SVG or EPS.
Yep, any suggestion to improve the .plot files? like kind of conditional generation of
PDF?
Apparently, there's a license issue with libpdflite (which gnuplot uses to generate
PDFs)... so some distro's won't have it installed.
Thanks,
