With this series, we are getting very close to obsoleting qemu-kvm. It
refactors hw/device-assignment.c and the associated KVM helper functions
into a form that should allow merging them into QEMU. Once the series is
acceptable for qemu-kvm, I will break out the necessary uq/master
patches and push pci-assign to upstream.
The major step of this series is to define a regular set of kvm_device_*
services that encapsulate classic (i.e. KVM-based, non-VFIO) device
assignment features and export them to i386 targets only. There will
never be another arch using them, therefore I pushed them into this
corner. Moreover, the device assignment device now makes use of the new
KVM IRQ/MSI routing API and no longer pokes into the internals of that
layer. Finally, I moved the code into hw/kvm/pci-assign.c, dropped the
superfluous configure option and did some basic code cleanups (mostly
coding style) to bring things in shape.
Note that patch 1 is a simple bug fix that should likely be applied for
qemu-kvm-1.2 independently.
Changes in v2:
- rebased over qemu-kvm next
- consistently clear unused IOCTL fields via structure initialization
