Registers
| register | value |
|---|---|
D1Re0 | 270, the syscall number |
D1Ar1 | pid_t pid |
D0Ar2 | const struct iovec *lvec |
D1Ar3 | unsigned long liovcnt |
D0Ar4 | const struct iovec *rvec |
D1Ar5 | unsigned long riovcnt |
D0Ar6 | 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.
This architecture was removed from the Linux kernel in Linux 4.17. The newest release with a syscall table here is Linux 4.16. The other removed architectures live on the historical architectures page.
