Just a few small points: (1) I've built Fedora RPMs from this patch set [approximately - I'm using a very slightly different / slightly older version, but it's not substantively different]:
http://copr-fe.cloud.fedoraproject.org/coprs/rjones/riscv/ It works well for me building plenty of Fedora packages over the past few weeks, except for a possible Linux kernel bug which interacts with the patch set not handling EBREAK correctly, which I had to patch around (in the kernel): https://groups.google.com/a/groups.riscv.org/forum/#!msg/sw-dev/v05FjcGC1EI/atXXUAcsCgAJ (2) I'm worried that this patch starts off using virtio-mmio instead of virtio-pci. virtio-pci is better in every respect than virtio-mmio, and while it may be a good interim solution I think we need to have a plan to get rid of it eventually, and should make it clear that virtio-mmio is not a permanent ABI so we don't get into the same situation that we did with -M virt on ARM. (3) poweroff doesn't work if you use -M virt (and hence don't use HTIF). I wrote a dummy poweroff device to get around this, but I think it could raise a bigger point: Why bother to support HTIF machine types at all? The reason given in the patch set is because spike (the cycle-accurate RISC-V emulator) only supports HTIF but is that a good reason?
