From: Roland Dreier Date: Thu, 24 Sep 2009 21:52:36 +0000 (-0700) Subject: ACPI: Kill overly verbose "power state" log messages X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3d5b6fb47a8e68fa311ca2c3447e7f8a7c3a9cf3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ACPI: Kill overly verbose "power state" log messages I was recently lucky enough to get a 64-CPU system, so my kernel log ends up with 64 lines like: ACPI: CPU0 (power states: C1[C1] C2[C3]) This is pretty useless clutter because this info is already available after boot from both /sys/devices/system/cpu/cpu*/cpuidle/state?/ as well as /proc/acpi/processor/CPU*/power. So just delete the code that prints the C-states in processor_idle.c.
