Hi Rusty, I'm using a patch that changes the Linux base page size to 64K. (This is actually pretty common in ppc64 world, but I happen to be trying it on ppc32.) I'm seeing a problem with virtio. I think at least part of it can be explained by qemu's TARGET_PAGE_BITS==12, and the guest's PAGE_SHIFT==16. The guest allocates the queue, then passes the pfn (pa >> PAGE_SHIFT) to the virtio backend (vp_find_vq()). The backend then calculates the pa as pfn << TARGET_PAGE_BITS. I have to run right now, but quickly changing qemu TARGET_PAGE_BITS to 16 got me a little further but still didn't work. Any thoughts?
