This series of patches are intended to further split x86 specific code

You mean the guest hangs, right? What'
This patch introduces support for device passthrough
from the host to a paravirtualized guest.
A new command-line option, -passthrough is added.
For example, to invoke it for an Ethernet device sitting at
PCI bus:dev.fn 04:08.0 with host IRQ 18, use this:
-passthrough Ethernet/04:08.0-18
The hos
This kernel module injects IRQs specified on the command line
via the passthrough parameter
This doesn't handle shared interrupts.
These patches don't yet work with the in-kernel apic, so you have
to use -no-kvm-irqchip.
These will soon be overridden by a new mechanism that utilises

This patchset is work in progress and is sent out for comments.
Guests within KVM can have paravirtualized DMA access. I've tested
the e1000 driver, and that works fine. A few problems/conditions to
get things to work:
- The pv driver should only be used as a module. If built into the
kernel,
A guest can call dma_ops->is_pv_device() to find out
if a device is a passthrough'ed device (device passed
on to a guest by the host). If this is true, a hypercall
will be made to translate DMA mapping operations.
This function can be done away with and just a
kvm_is_pv_device() call can be added,
This is to be enabled on a guest. Currently, only
'module' works; compiling it in freezes at HD bringup

Introduce three hypercalls and one ioctl for enabling guest

An ioctl comes from userspace (qemu) to notify of a physical
device being assigned to a guest. Guests make a hypercall (once

and if any DMA translations are neces
