timerfd_settime64

timers that notify via file descriptors

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

register	value
`eax`	411, the syscall number
`ebx`	int ufd
`ecx`	int flags
`edx`	const struct __kernel_itimerspec *utmr
`esi`	struct __kernel_itimerspec *otmr
`eax`	the return value

Then run int 0x80 to enter the kernel.

Same syscall on other architectures
