FWIW, this will happen, regardless of what we do:
[ 0.089350] x86: Booting SMP configuration:
[ 0.104355] NMI watchdog: enabled on all CPUs, permanently consumes one hw-PMU counter.
[ 0.089427] .... node #0, CPUs: #1 #2 #3
[ 0.136301] x86: Booted up 1 node, 4 CPUs
[ 0.136442] smpboot: Total of 4 processors activated (23146.32 BogoMIPS)
as the NMI watchdog thing keeps shouting in-between. Do we still need it
- I mean, how can I really use the info that NMI watchdog is consuming a
perf counter? I mean I know how, but do people actually use that info or
everyone knows already? :-)
Thanks.
