System V message queue operations
sys_msgrcv(int msqid, struct msgbuf *msgp, size_t msgsz, long msgtyp, int msgflg)| number | 188 (0xbc) |

| abi | common |
| kconfig | CONFIG_SYSVIPC |
| family | sysvipc see the whole family on score |
| entry point | sys_msgrcv |

Registers
| register | value |
|---|---|
r27 | 188, the syscall number |
r4 | int msqid |
r5 | struct msgbuf *msgp |
r6 | size_t msgsz |
r7 | long msgtyp |
r8 | int msgflg |
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.
