shmctl on tilepro
System V shared memory control
sys_shmctl(int shmid, int cmd, struct shmid_ds *buf)| number | 195 (0xc3) |
|---|---|
| abi | common |
| kconfig | CONFIG_SYSVIPC |
| family | sysvipc see the whole family on tilepro |
| entry point | sys_shmctl |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |

Registers
| register | value |
|---|---|
r10 | 195, the syscall number |
r0 | int shmid |
r1 | int cmd |
r2 | struct shmid_ds *buf |
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.
