| |
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
