![]() The modifiers: k kernel space u user space h hypervisor G guest H host p, pp, ppp precision level (PEBS) that can be suffixed to an event were lost when tools used event_name() to reconstruct them from the perf_event_attr entries in a perf.data file. Fix it by following the defaults used for these modifiers in the current codebase, so: $ perf record -e instructions:u usleep 1 2> /dev/null $ perf evlist instructions:u $ perf record -e cycles:k usleep 1 2> /dev/null $ perf evlist cycles:k $ perf record -e cycles:kh usleep 1 2> /dev/null $ perf evlist cycles:kh $ perf record -e cache-misses:G usleep 1 2> /dev/null $ perf evlist cache-misses:G $ perf record -e cycles:ppk usleep 1 2> /dev/null $ perf evlist cycles:kpp $ Also works with 'top', 'report', etc. More work needed to cover tracepoints and software events while not dragging lots of baggage to the python binding, this is a minimal fix for v3.5.
