fchmodat on tilepro
change permissions of a file
sys_fchmodat(int dfd, const char *filename, umode_t mode)| number | 53 (0x35) |
|---|---|
| abi | common |
| entry point | sys_fchmodat |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | fchmodat(2) |

Registers
| register | value |
|---|---|
r10 | 53, the syscall number |
r0 | int dfd |
r1 | const char *filename |
r2 | umode_t mode |
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.
