Hi,
Is there any place where sched_clock() usage might not be safe. Like lets say early in the boot during driver probe ?
Or any things that i need to ensure before calling sched_clokc() ?
Thanks and regards, Vignesh Radhakrishnan

Quite likely, you can't call sched_clock inside interrupt handler or similar place where interrupts are disabled or atomicity must be maintained. CMIIW -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
