In any case, you enable the syscalls here but don't assign a system call number, so that is rather pointless. I I might be missing something though.

Which host bridge do you use? Are you sure there is no I/O space? Most of them use a set of translation windows to set up a mapping between bus address (memory, config and io space) and physical (mmio) space. > diff --git a/arch/nios2/include/asm/pci.h b/arch/nios2/include/asm/pci.h > new file mode 100644 > index 0000000..f2cba05 > --- /dev/null > +++ b/arch/nios2/include/asm/pci.h What happens if you use the asm-generic header? If there is something missing in it, we can try to get it to do the right things.
