Registers
| register | value |
|---|---|
a7 | 271, the syscall number |
a0 | pid_t pid |
a1 | const struct iovec *lvec |
a2 | unsigned long liovcnt |
a3 | const struct iovec *rvec |
a4 | unsigned long riovcnt |
a5 | unsigned long flags |
a0 | the return value |
Then run syscall 0 to enter the kernel.
