Why is sched_clock called in init_idle? Do you get any non zero value on
any ARCH?
Yes, some architectures return a real-time value here that starts before boot.
Also, when the clock starts at boot time, there can be a significant time
spent in the firmware and early kernel code before we get to init_idle.
ok. I will return 0 before timer initialization.
Thanks for explanation,
