copy_file_range on tilepro
Copy a range of data from one file to another
sys_copy_file_range(int fd_in, loff_t *off_in, int fd_out, loff_t *off_out, size_t len, unsigned int flags)| number | 285 (0x11d) |
|---|---|
| abi | common |
| entry point | sys_copy_file_range |
| since | Linux 4.5 |
| man page | copy_file_range(2) |

Registers
| register | value |
|---|---|
r10 | 285, the syscall number |
r0 | int fd_in |
r1 | loff_t *off_in |
r2 | int fd_out |
r3 | loff_t *off_out |
r4 | size_t len |
r5 | unsigned int 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.
