LinuxLists.cc - [PATCH] sched/clock: Fix local_clock() before sched_clock

2023-04-06 04:20:38

Subject: [PATCH] sched/clock: Fix local_clock() before sched_clock_init()

Have local_clock() return sched_clock() if sched_clock_init() has not
yet run. sched_clock_cpu() has this check but it was not included in the
new noinstr implementation of local_clock().

The effect can be seen on x86 with CONFIG_PRINTK_TIME enabled, for
instance. scd->clock quickly reaches the value of TICK_NSEC and that
value is returned until sched_clock_init() runs.

dmesg without this patch:
