pwritev on metag
read or write data into multiple buffers
sys_pwritev(unsigned long fd, const struct iovec *vec, unsigned long vlen, unsigned long pos_l, unsigned long pos_h)| number | 70 (0x46) |
|---|---|
| abi | common |
| entry point | sys_pwritev |
| since | Linux 3.9 or earlier (3.9 is the first release scanned for metag) |
| man page | pwritev(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
D1Re0 | 70, the syscall number |
D1Ar1 | unsigned long fd |
D0Ar2 | const struct iovec *vec |
D1Ar3 | unsigned long vlen |
D0Ar4 | unsigned long pos_l |
D1Ar5 | unsigned long pos_h |
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.
