Registers

r10189, the syscall number
r0int msqid
r1struct msgbuf *msgp
r2size_t msgsz
r3int msgflg
r0the 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.
