Registers

r1076, the syscall number
r0int fd_in
r1loff_t *off_in
r2int fd_out
r3loff_t *off_out
r4size_t len
r5unsigned int flags
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.

Same syscall on other architectures
