process_vm_readv on tilepro
transfer data between process address spaces
sys_process_vm_readv(pid_t pid, const struct iovec *lvec, unsigned long liovcnt, const struct iovec *rvec, unsigned long riovcnt, unsigned long flags)| number | 270 (0x10e) |
|---|---|
| abi | common |
| entry point | sys_process_vm_readv |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | process_vm_readv(2) |

Registers
| register | value |
|---|---|
r10 | 270, the syscall number |
r0 | pid_t pid |
r1 | const struct iovec *lvec |
r2 | unsigned long liovcnt |
r3 | const struct iovec *rvec |
r4 | unsigned long riovcnt |
r5 | unsigned long 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.
