The pxe-test is a very good test to excercise NICs, thus we should use
it to test all NICs that can be used by the BIOS for booting via network.
However, to avoid that the default testing time increases too much, the
additional NICs are only tested in the "make check SPEED=slow" mode.
The virtio-net NIC on ppc64 is now also only tested in slow mode, since
the test on ppc64 is really quite slow and we've got test coverage for
virtio-net in big endian mode now on s390x, too.

The modern bar is accessed now via yet another address space created just
for that purpose and it does not really need FlatView and dispatch tree
as it has a single memory region so it is just a waste of memory. Things
get even worse when there are dozens or hundreds of virtio-pci devices -
since these address spaces are global, changing any of them triggers
rebuilding all address spaces.
This replaces indirect accesses to the modern BAR with a simple lookup
and direct calls to memory_region_dispatch_read/write.

While changing the s/g list allocation, commit 3b3b0628
also changed the descriptor counting to count iovec entries

Count the entries again instead to avoid erroneous

* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci

* dec-21154-p2p-bridge

* pcie-port: all non-abstract subtypes of pcie-port are already

3) megasas-base
Not all megasas devices are Conventional PCI devices, so the

megasas_register_types(), according to information in the

vhost_log_put() is called to decomission the dirty log between qemu and
a vhost device when stopping the device. Such a call can happen from
migration_completion().
Present code sets dev->log_size to zero too early in vhost_log_put(),
causing the sync check to always return false. As a consequence, the
last pass on the dirty bitmap never happens at the end of migration.
If a vhost device was busy (writing to guest memory) until the last
moments before vhost_virtqueue_stop(), this error will result in guest
memory corruption (at least) following migrations.

This change introduces a new TPM backend driver that can communicate with
swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to
the TPM emulator using QEMU's socket-based chardev backend device.
Swtpm uses two Unix sockets for communications, one for plain TPM commands and
responses, and one for out-of-band control messages. QEMU passes the data
socket to be used over the control channel.
The swtpm and associated tools can be found here:
https://github.com/stefanberger/swtpm
The swtpm's control channel protocol specification can be found here:
https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification
Usage:
# setup TPM state directory
mkdir /tmp/mytpm
chown -R tss:root /tmp/mytpm

# Ask qemu to use TPM emulator with given tpm state directory
