Many moons ago (2009?) I built an alpha toolchain, userspace, and =20 kernel, but couldn't boot it under qemu because there was no =20 qemu-system-alpha. what I'd like to do is build a 3.10 kernel with: 1) Serial console on qemu's stdin/stdout. 2) Block device driver of some kind (ide, scsi, virtio...) 3) network card 4) at least 256 megs memory 5) battery backed up clock > The IOMMU was a bit of a pipe dream 2 years ago, and only in the last =20 > 3-4 > months has the code enabling that actually gotten merged.
