I have tried to find these users but it seems they do not exist. users need to set IXP4XX_INDIRECT_PCI to make use of it and the only existing userspace for IXP4XX is OpenWrt and they do not enable this. Krzysztof Halasa talks about using it for a VGA card at one point: https://lore.kernel.org/linux-arm-kernel/m37edwuv8m.fsf@xxxxxxxxxxx/ The plan is to locate these users (if I can) and in case they need this use an idea from Linville for indirect PCI access, if they can provide testing (I have nothing to test on unfortunately...) I can't find Linville's patch right now but Arnd pointed it out to me. I fixed all the other comments in my tree. Yours, Linus Walleij
