Registers
| register | value |
|---|---|
D1Re0 | 234, the syscall number |
D1Ar1 | unsigned long start |
D0Ar2 | unsigned long size |
D1Ar3 | unsigned long prot |
D0Ar4 | unsigned long pgoff |
D1Ar5 | unsigned long flags |
D0Re0 | the return value |
Then run SWITCH #0x440001 to enter the kernel.
Values wider than one register are packed into consecutive arguments.
