SubjectQuestion: Takes about 2s in sched_clock_init() when kernel boots
Hi,
When I analyse boot time on ArmV7, I found that it takes
about 2s in sched_clock_init(), the log is as follow:
[ 0.000000] before:sched_clock_init.
[ 0.000000] start:sched_clock_init.
[ 2.100505] end :sched_clock_init.
[ 2.103983] before:calibrate_delay.

In my config, CONFIG_HAVE_UNSTABLE_SCHED_CLOCK does not config.

Are there any suggestions?

Younger
