semtimedop on score
System V semaphore operations
sys_semtimedop(int semid, struct sembuf *sops, unsigned nsops, const struct timespec *timeout)| number | 192 (0xc0) |
|---|---|
| abi | common |
| kconfig | CONFIG_SYSVIPC |
| family | sysvipc see the whole family on score |
| entry point | sys_semtimedop |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |

Registers
| register | value |
|---|---|
r27 | 192, the syscall number |
r4 | int semid |
r5 | struct sembuf *sops |
r6 | unsigned nsops |
r7 | const struct timespec *timeout |
r4 | the return value |
Then run syscall to enter the kernel.
r7 is the error flag and r4 then holds the positive error number.
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.
