https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207068 --- Comment #8 from joss.upton@yahoo.com --- (In reply to Konstantin Belousov from comment #7) Not sure why you can't reproduce, but I'm doing the equivalent of the shell script below. Note the ",usr" and the lowercase p. On a 4 core machine: while true; do for a in 1 2 3 4 5 6 7 8; do pmcstat -p CPU_CLK_UNHALTED_CORE,usr perl loop.pl & done sleep 10 killall perl done This ensures that the PMCs are csw in/out very often (every hz). --=20 You are receiving this mail because: You are on the CC list for the bug.=
