timerfd_settime

timers that notify via file descriptors

sys_timerfd_settime(int ufd, int flags, const struct __kernel_itimerspec *utmr, struct __kernel_itimerspec *otmr)

register	value
`g1`	315, the syscall number
`o0`	int ufd
`o1`	int flags
`o2`	const struct __kernel_itimerspec *utmr
`o3`	struct __kernel_itimerspec *otmr
`o0`	the return value

Then run t 0x6d to enter the kernel.

Same syscall on other architectures
