Registers

registervalue
r2767, the syscall number
r4unsigned int fd
r5char *buf
r6size_t count
r7loff_t pos
r4the 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.
