You could set a timer.
Hum, do we really want to do this?
I'm pretty sure that the compiler optimizes empty loops away. Maybe have
a look at the disassembly of your delay function...
Anyway, it's likely better to use STCK and friends to get a proper
timing. You could move get_clock_ms() from s390x/intercept.c to the
lib/s390x folder and then use that function here.
Yes, I can, thanks.
