vfio: Fix debug output for int128 values

Memory regions can easily be 2^64 byte long and therefore overflow
for just a bit but that is enough for int128_get64() to assert.

This takes care of debug printing of huge section sizes.

vfio-pci: Implement PCI hot reset

Now that VFIO has a PCI hot reset interface, take advantage of it.
There are two modes that we need to consider. The first is when only
one device within the set of devices affected is actually assigned to
the guest. In this case the other devices are are just held by VFIO...

vfio-pci: Add support for MSI affinity

When MSI is accelerated through KVM the vectors are only programmed
when the guest first enables MSI support.  Subsequent writes to the
vector address or data fields are ignored.  Unfortunately that means
we're ignore updates done to adjust SMP affinity of the vectors....

vfio-pci: Test device reset capabilities

Not all resets are created equal. PM reset is not very reliable,
especially for GPUs, so we might want to opt for a bus reset if a
standard reset will only do a D3hot->D0 transition. We can also
use this to tell if the standard reset will do a bus reset (if...

vfio-pci: Lazy PCI option ROM loading

During vfio-pci initfn, the device is not always in a state where the
option ROM can be read. In the case of graphics cards, there's often
no per function reset, which means we have host driver state affecting
whether the option ROM is usable. Ideally we want to move reading the...

vfio: QEMU-AER: Qemu changes to support AER for VFIO-PCI devices

Add support for error containment when a VFIO device assigned to a KVM

vfio-pci: VGA quirk update

Turns out all the suspicions for AMD devices were correct, everywhere
we read a BAR address that the address matches the config space offset,
there's full access to PCI config space. Attempt to generalize some
helpers to allow quirks to easily be added for mirrors and windows....

Add ref/unref calls at the following places:
