Hi list, I have done experiments and it seems that FreeBSD's libc function clock_gettime() results in a system call when running on QEMU whereas on hardware it does not. Does anybody know why? For those interested , you can find the clock_gettime libc call in freebsd source here: https://github.com/lattera/freebsd/blob/master/lib/libc/sys/clock_gettime.c
Thanks!
