Registers
| register | value |
|---|---|
D1Re0 | 4, the syscall number |
D1Ar1 | aio_context_t ctx_id |
D0Ar2 | long min_nr |
D1Ar3 | long nr |
D0Ar4 | struct io_event *events |
D1Ar5 | struct timespec *timeout |
D0Re0 | the return value |
Then run SWITCH #0x440001 to enter the kernel.
Values wider than one register are packed into consecutive arguments.
