[Xen-devel] [PATCH v4 0/4] x86/dpci: bind legacy PCI interrupts to PVHv2 Dom0

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following patches allow binding bare-metal GSIs into a PVHv2 Dom0,
by snooping on the vIO APICs writes made by Dom0.

First patch is a cleanup of an unused field from the bind structure,
patches 2 and 3 introduce the necessary code to bind GSIs into a PVH
Dom0, and patch 4 snoops on vIO APIC writes for unmask and binds the
GSI to Dom0.

The series has been tested with a PVHv2 Dom0 on a box with 3 IO APICs,
although all devices are wired up into the first IO APIC sadly.

A branch with the changes can be found at:

git://xenbits.xen.org/people/royger/xen.git dom0_gsi_v4

Thanks, Roger.
