Description Frank Ch. Eigler 2010-05-06 19:01:49 UTC 
In runtime/perf.c, it should be a straightforward thing to
detect that we're running in target-process mode (stap -c/-x),
and interpret that as a request to bind the perf.* events
only to that process.  (One would pass a -1 cpu and a proper
pid number to perf_event_create_kernel_counter.)

OTOH, this could be an option at the probe point level, as in
probe process(NNN).perf.* ?
Comment 1 Frank Ch. Eigler 2012-11-05 16:36:57 UTC 
In order to enjoy the tapset/perf.* aliasing for perfctr names,
instead of process(...).perf*, the new probe points could be named
perf.*.process("..."), relying on bug #14313's suffix-passthrough
magic.
Comment 2 Stan Cox 2013-01-28 19:45:16 UTC 
Add process("NAME") to perf probe.
