mq_timedsend

send a message to a message queue

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

register	value
`g1`	275, the syscall number
`o0`	mqd_t mqdes
`o1`	const 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
