| abi | common |
| kconfig | CONFIG_KEYS |
| family | keys see the whole family on metag |

Registers
| register | value |
|---|---|
D1Re0 | 219, the syscall number |
D1Ar1 | int cmd |
D0Ar2 | unsigned long arg2 |
D1Ar3 | unsigned long arg3 |
D0Ar4 | unsigned long arg4 |
D1Ar5 | unsigned long arg5 |
D0Re0 | the return value |
Then run SWITCH #0x440001 to enter the kernel.
Values wider than one register are packed into consecutive arguments.
