What version of linux should I expect to contain a version of perf that knows about libopencsd?
Debian is currently at 4.15.11. Is that new enough? It contains a tools/perf/arch/arm/util/cs-etm.c and tools/include/linux/coresight-pmu.h
but if I build perf (with make VF=1 -C tools/perf ) then Auto-detecting system features: does not mention libopencsd.
but then make it doesn't try on x86?
some clue about whether to expect this to work with 4.15.11, or if I need a newer mainline, or if that is not sufficient, and I still need the perf-opencsd-master mentioned in the HOWTO would be useful. Or perhaps https://github.com/Linaro/perf-opencsd is the place to go?
Also how does the enabling machinery work?
I can't enable this in debian until a) its in the debian mainline kernel packages and b) libopencsd is uploaded, but I can mess with it locally and get bugs filed to make it work in due course.
Wookey
