At least something. I haven't looked into the qemu-ppc implementation of cmd646, does it support DMA? (qemu-sparc64 doesn't ant that's the reason why Linux cmd646 driver fails).
That's a good point. I see there are functions in QEMU's hw/ide/cmd646.c called bmdma_read() and bmdma_write() which would suggest that DMA is supported?
Yes. On Sparc64 we'd probably have to implement the IOMMU for DMA to work.
