Advanced Use: Kernel Profiles


Command line switch:  "-V k"  (exclusive of -V[2-4]) will create kernel profiles in the output

NMI-based sampling is imperative for correct kernel profiles

Four profiles created:
Global kernel profile: all kernel hits for everybody
Kernel profile due to kernel threads
Kernel profile due to user processes
Kernel profile of hits to process zero (interrupts)

Note: The first profile above is the sum of the others
