Registers
| register | value |
|---|---|
D1Re0 | 285, the syscall number |
D1Ar1 | int fd_in |
D0Ar2 | loff_t *off_in |
D1Ar3 | int fd_out |
D0Ar4 | loff_t *off_out |
D1Ar5 | size_t len |
D0Ar6 | unsigned int flags |
D0Re0 | the return value |
Then run SWITCH #0x440001 to enter the kernel.
Values wider than one register are packed into consecutive arguments.
