PmcTools Kcachegrind support allow full inspection of pmc capture under Kcachegrind (kde4sdk).

Sample command:

pmcstat -Sinstructions -O/tmp/pmctest.bin ~/pmctest/prog/pmctest 1000

pmcstat -R/tmp/pmctest.bin -F/tmp/pmctest.cg

/usr/local/kde4/bin/kcachegrind /tmp/pmctest.cg

Tips:

• if you want to merge PMC (useful for SMP capture): edit .cg and put the same name on events: line.
• call count is actually roughly estimated by detecting when two consecutive sample hit with a distance > 1
