Hi,
The thermal throttle event support code located in arch/x86/kernel/cpu/mcheck/therm_throt.c
which handles thermal interrupts if CONFIG_X86_MCE_INTEL is set to 'y'
causes too much noise in the kernel ring buffer:
$ dmesg | grep "Package power" | wc -l
392
Actually I think it would be more efficient to just print critical events
(cpu throttling) in syslog and mcelog and leave benign notifications
in /sys/devices/system/cpu/cpu#/thermal_throttle/
So do you think getting rid of these messages would be acceptable?
Cheers,
Vincent
P.S: I know I could restrict the output of 'dmesg' to not take into
account KERN_INFO but that's quite annoying ;-)
