What version of linux should I expect to contain a version of perf that knows about libopencsd?
Anyway, to answer your question, you'd need a 4.16 based kernel tree to get the perf that does things libopencsd.
OK. cheers
BTW, is this debian decoder library package going to be available for both x86 and Arm debians? I'd like to be able to do both perf record and report on the Arm target, if at all possible.
Yes, libopencsd will be built on all debian arches so you can decode arm traces on any machine. Once I have a suitably-built perf, I'll check that this does indeed work, and then enable it in the standard linux-tools build, so that anyone using packaged perf will find it all 'just works'.
I assume that the next debian stable will have at least 4.16 so this should be straightforward. There is a 4.16~rc6 in experimental already, so I'll test with that.
