Thanks for the information.
Hum, so I grabbed perfmon2 git tree, installed various tools...
I am quite new to pfmon and tried :
# pfmon --system-wide sizeof=64 44 <press ENTER to stop session>
Then started "tbench 8", and got a kernel panic after 6 seconds.
I was using oprofile like this
opcontrol --vmlinux=/path/vmlinux --start // doing some benchmarking... opreport -l vmlinux | head -n 40
What would be a working equivalent for perfmon2 based tools ?
Thanks
