Hi Stephane, just tried it again. I had PFMROOTDIR=/root/libpfm in the config.mk
mars:~/pfmon # ./pfmon/pfmon --system-wide --smpl-outfile=/tmp/sample.out.31070 --smpl-entries=100 -u -k --short-smpl-periods=15940000 --smpl-module=compact --events=CPU_OP_CYCLES_ALL --cpu-list=0 -- dd if=/dev/zero of=/dev/null count=10000 cannot write PMCs: Invalid argument We have a 16p Montecito test system. I copied everything over there and see the same problem. I could get you full access to this system, if you need something to play with. @Robin: Will do in second.
