[[ Problem with machines that can only dma into memory on a pci bridge
: I suspect the only systems on which this is really an issue are those
: which have a PCI bus that's designed to deal with exactly one device.
NetBSD/arc might support the Deskstation Tyne. The Tyne is a EISA
machine that has lots of slots (6 or 8 I think), but can only DMA into
a fixed SRAM area. I've not looked at that, but wanted to give
another example. The SRAM area is on the order of 64k iirc. I don't
actually have one, I have its ancestor the Desktation rPC44.
