clock_nanosleep

high-resolution sleep with specifiable clock

sys_clock_nanosleep(clockid_t which_clock, int flags, const struct __kernel_timespec *rqtp, struct __kernel_timespec *rmtp)

register	value
`g1`	259, the syscall number
`o0`	clockid_t which_clock
`o1`	int flags
`o2`	const struct __kernel_timespec *rqtp
`o3`	struct __kernel_timespec *rmtp
`o0`	the return value

Then run t 0x6d to enter the kernel.

Same syscall on other architectures
