I've started to get my qemu magnum setup working again. Later I'm also going to get my M700 running. For your dma rework: How about ignoring the vdma stuff and treat jazz like other non cohoherent MIPS. Then I'll implement the vdma stuff similair to other iommu hardware. Is this goog enough for you ? Thomas. -- Crap can work. Given enough thrust pigs will fly, but it's not necessarily a good idea. [ RFC1925, 2.3 ]
