Public bug reported:
perf in linux-tools-common_4.8.0-27.29 seems to be compiled without auxtrace
support. This prevents perf from using Intel Processor Trace (PT) or Branch
Trace Store (BTS). Unfortunately, rather than indicating that auxtrace is
missing, perf just records no samples:
# grep -
I haven't tried any previous Ubuntu or kernel releases. I'm not doing
anything special to compile perf myself, i.e., I just run make in
tools/perf. Looking at tools/perf/Makefile.config, it seems like
auxtrace gets disabled if GCC is detected to not have __get_cpuid, which
makes it seems like a bug
Seems to work now.
