Subject: make the dma interface useable.
X-Git-Tag: m5_1.0_beta2~141
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ec06c63cc7a63111e9d21936a302901c552ad36b;hp=695d51e5137f43052dc54e211eb1ab239100008d;p=gem5.git

make the dma interface useable.
make it so that pio devices must respond with some delay.

dev/io_device.cc:
    don't forget to include dma_interface.hh so we could use it.
dev/io_device.hh:
    the generic BusInterface isn't enough for doing DMA
    we need the actual DMAInterface
