Hi all,
after some preliminary discussion on the QEMU mailing list, I present a
draft specification for a virtio-based SCSI host (controller, HBA, you

KVM. This stack would overcome several limitations of the current

Current code might introduce a lot of latency variation

OK, here's a new attempt to use the new capacity api. I also added more
comments to clarify the logic. Hope this is more readable. Let me know
pls.
This is on top of the patches applied by Rusty.

Now, make the vmbus driver an ACPI bus driver.
Why an ACPI bus driver and not a PCI one? Is that what this really is?
For some reason, I thought it was a PCI device that we hooked our bus
off of, is that not true?

Thanks Greg. Can you give me some pointers here as to what needs to be
done here. Looking at the code for virtio, it looks like I would need to add
stuff
to scripts/mod/file2alias.c as well as to include/linux/mod_devicetable.h.
