read or write data into multiple buffers
sys_pwritev2(unsigned long fd, const struct iovec *vec, unsigned long vlen, unsigned long pos_l, unsigned long pos_h, rwf_t flags)| number | 287 (0x11f) |

Registers
| register | value |
|---|---|
r10 | 287, the syscall number |
r0 | unsigned long fd |
r1 | const struct iovec *vec |
r2 | unsigned long vlen |
r3 | unsigned long pos_l |
r4 | unsigned long pos_h |
r5 | rwf_t flags |
r0 | the return value |
Then run swint1 to enter the kernel.
The kernel uses r1 to signal an error for ordinary calls.
Fast atomic calls use negative numbers and have different register behavior.
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.
