Registers

registervalue
r10269, the syscall number
r0int fd
r1struct mmsghdr *mmsg
r2unsigned int vlen
r3unsigned 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.
