semop on tilepro
System V semaphore operations
sys_semop(int semid, struct sembuf *sops, unsigned nsops)| number | 193 (0xc1) |
|---|---|
| abi | common |
| kconfig | CONFIG_SYSVIPC |
| family | sysvipc see the whole family on tilepro |
| entry point | sys_semop |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | semop(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r10 | 193, the syscall number |
r0 | int semid |
r1 | struct sembuf *sops |
r2 | unsigned nsops |
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.
