6f7a4a81ce scripts: add __init__.py file to scripts/qmp/
When searching for modules to load, python will ignore any
sub-directory which does not contain __init__.py. This means
that both scripts and scripts/qmp/ have to be explicitly added
to the python path. By adding a __init__.py file to scripts/qmp,
we only need add scripts/ to the python path and can then simply
do 'from qmp import qmp' to load scripts/qmp/qmp.py.

42da5550d6 migration: set state to post-migrate on failure
If a migration fails/is cancelled during the postcopy stage we currently
end up with the runstate as finish-migrate, where it should be post-migrate.
There's a small window in precopy where I think the same thing can
happen, but I've never seen it.

It rarely matters; the only postcopy case is if you restart a migration, which
again is a case that rarely matters in postcopy because it's only
safe to restart the migration if you know the destination hasn't
been running (which you might if you started the destination with -S
and hadn't got around to 'c' ing it before the postcopy failed).
Even then it's a small window but potentially you could hit if
there's a problem loading the devices on the destination.

This corresponds to:

38d87493f3 kvm-irqchip: i386: add hook for add/remove virq
Adding two hooks to be notified when adding/removing msi routes. There
are two kinds of MSI routes:

- in kvm_irqchip_add_irq_route(): before assigning IRQFD. Used by
  vhost, vfio, etc.

- in kvm_irqchip_send_msi(): when sending direct MSI message, if
  direct MSI not allowed, we will first create one MSI route entry
  in the kernel, then trigger it.

This patch only hooks the first one (irqfd case). We do not need to
take care for the 2nd one, since it's only used by QEMU userspace
(kvm-apic) and the messages will always do in-time translation when
triggered. While we need to note them down for the 1st one, so that we
can notify the kernel when cache invalidation happens.

Also, we do not hook IOAPIC msi routes (we have explicit notifier for
IOAPIC to keep its cache updated). We only need to care about irqfd
users.

even if the invalidated entries are not IOAPIC ones.

8b5ed7dffa intel_iommu: add support for split irqchip
In split irqchip mode, IOAPIC is working in user space, only update
kernel irq routes when entry changed. When IR is enabled, we directly
update the kernel with translated messages. It works just like a kernel
cache for the remapping entries.

Since KVM irqfd is using kernel gsi routes to deliver interrupts, as
long as we can support split irqchip, we will support irqfd as
well. Also, since kernel gsi routes will cache translated interrupts,
irqfd delivery will not suffer from any performance impact due to IR.

And, since we supported irqfd, vhost devices will be able to work
seamlessly with IR now. Logically this should contain both vhost-net and
vhost-user case.

cb135f59b8 q35: ioapic: add support for emulated IOAPIC IR
This patch translates all IOAPIC interrupts into MSI ones. One pseudo
ioapic address space is added to transfer the MSI message. By default,
it will be system memory address space. When IR is enabled, it will be
IOMMU address space.

Currently, only emulated IOAPIC is supported.

Idea suggested by Jan Kiszka and Rita Sinha in the following patch:

2165477c0f crypto: use glib as fallback for hash algorithm
GLib >= 2.16 provides GChecksum API which is good enough
for md5, sha1, sha256 and sha512. Use this as a final
fallback if neither nettle or gcrypt are available. This
lets us remove the stub hash impl, and so callers can
be sure those 4 algs are always available at compile
time. They may still be disabled at runtime, so a check
for qcrypto_hash_supports() is still best practice to
report good error messages.
