mq_timedreceive

receive a message from a message queue

sys_mq_timedreceive(mqd_t mqdes, char *msg_ptr, size_t msg_len, unsigned int *msg_prio, const struct __kernel_timespec *abs_timeout)

register	value
`g1`	276, the syscall number
`o0`	mqd_t mqdes
`o1`	char *msg_ptr
`o2`	size_t msg_len
`o3`	unsigned int *msg_prio
`o4`	const struct __kernel_timespec *abs_timeout
`o0`	the return value

Then run t 0x6d to enter the kernel.

Same syscall on other architectures
