Registers

registervalue
r1029, the syscall number
r0unsigned int fd
r1unsigned int cmd
r2unsigned long arg
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
