hot-unpluging virtio-blk disks which are hotplugged into
pcie-root-port, the VM's dmesg log shows:

After analyzing the log information, it seems that qemu doesn't
change the Link Status from active to inactive after hot-unplug.
This results in the abnormal log after the linux kernel commit
d331710ea78fea merged.
Furthermore, If I hotplug the same virtio-blk disk after hot-unplug,
the virtio-blk would turn on and then back off.
So this patch set the Link Status inactive after hot-unplug and
active after hot-plug.

Introduce a helper for registering different flavours of virtio
devices. Convert code to use the helper, but keep only the
existing generic types. Transitional and non-transitional device
types will be added by another patch.

From: Eduardo Habkost <ehabkost@redhat.com>
Many of the current virtio-*-pci device types actually represent
3 different types of devices:
* virtio 1.0 non-transitional devices
* virtio 1.0 transitional devices
* virtio 0.9 ("legacy device" in virtio 1.0 terminology)
That would be just an annoyance if it didn't break our device/bus
compatibility QMP interfaces. With these multi-purpose device
types, there's no way to tell management software that
transitional devices and legacy devices require a Conventional
PCI bus.
The multi-purpose device types would also prevent us from telling
management software what's the PCI vendor/device ID for them,
because their PCI IDs change at runtime depending on the bus
where they were plugged.
This patch adds separate device types for each of those virtio
device flavors:
- virtio-*-pci: the existing multi-purpose device types
- Configurable using `disable-legacy` and `disable-modern`
properties
- Legacy driver support is automatically enabled/disabled
depending on the bus where it is plugged
- Supports Conventional PCI and PCI Express buses
(but Conventional PCI is incompatible with
disable-legacy=off)
- Changes PCI vendor/device IDs at runtime
- virtio-*-pci-transitional: virtio-1.0 device supporting legacy drivers
- Supports Conventional PCI buses only, because
it has a PIO BAR
- virtio-*-pci-non-transitional: modern-only
- Supports both Conventional PCI and PCI Express buses
The existing TYPE_* macros for these types will point to an
abstract base type, so existing casts in the code will keep
working for all variants.
A simple test script (tests/acceptance/virtio_version.py) is
included, to check if the new device types are equivalent to
using the `disable-legacy` and `disable-modern` options.

There is no need to have this include publicly exposed,
reduce the visibility by moving it in hw/smbios/.

This header only declare a single function: smbios_build_type_38_table().
We already have a header that declares such functions: "smbios_build.h".
Move the declaration and remove the header.

SMBIOS is just another firmware interface used by some QEMU models.
We will later introduce more firmware interfaces in this subdirectory.

From: Matthias Weckbecker <matthias@weckbecker.name>
When loadvm'ing a *running* snapshot qemu crashes due to an invalid
free. It's fortunately caught early by glibc heap memory corruption
protection and qemu gets killed with SIGABRT.
Steps to reproduce:
1) Create VM (e.g w/ virsh define)
2) Start the VM and take a snapshot while it's running and having a
PCI bridge attached
3) Destroy the VM and revert the running snapshot.
This commit fixes the issue.

From: Alex Williamson <alex.williamson@redhat.com>
The PCIe link speed and width between a downstream device and its
upstream port is negotiated on real hardware and susceptible to
dynamic changes due to signal issues and power management. In the
emulated device case there is no real hardware link, but we still
might wish to have some consistency between endpoint and downstream
port via a virtual negotiation. There is of course a real link for
assigned devices and this same virtual negotiation allows the
downstream port to match the endpoint, synchronizing on every read
to support underlying physical hardware dynamically adjusting the
link.
This negotiation is intentionally unidirectional for compatibility.
If the endpoint exceeds the capabilities of the downstream port or
there is no endpoint device, the downstream port reports negotiation
to its maximum speed and width, matching the previous case where
negotiation was absent. De-tuning the endpoint to match a virtual
link doesn't seem to benefit anyone and is a condition we've thus
far reported without functional issues.
Note that PCI_EXP_LNKSTA is already ignored for migration
compatibility via pcie_cap_v1_fill().

Create properties to be able to define speeds and widths for PCIe
links. The only tricky bit here is that our get and set callbacks
translate from the fixed QAPI automagic enums to those we define
in PCI code to represent the actual register segment value.

Add fields allowing the PCIe link speed and width of a PCIESlot to
be configured, with an instance_post_init callback on the root port
parent class to set defaults. This allows child classes to set these
via properties or via their own instance_init callback, without
requiring all implementions to support arbitrary user selected values.

Make use of the PCIESlot speed and width fields to update link
information beyond those configured in pcie_cap_v1_fill(). This is
only called for devices supporting a version 2 capability and
automatically skips any non-PCIESlot devices. Only devices with
increased link values generate any visible config space differences.

Allow users to experimentally specify speed and width values for the
generic PCIe root port. Defaults remain at 2.5GT/s & x1 for
compatiblity with the intent to only support changing defaults via
machine types for now.
Note for libvirt testing that pcie-root-port controllers are given
default names like "pci.7" which don't play well with using the
"-set device.$name.$prop=$value" options accessible to us via
<qemu:commandline> options. The solution is to add an <alias> to the
pcie-root-port <controller>, for example:
<controller type='pci' index='7' model='pcie-root-port'>
<model name='pcie-root-port'/>
<target chassis='7' port='0x15'/>
<alias name='ua-gfx0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x5'/>
</controller>
The "ua-" here is a mandatory prefix. We can then use:
<qemu:commandline>
<qemu:arg value='-set'/>
<qemu:arg value='device.ua-gfx0.x-speed=8'/>
<qemu:arg value='-set'/>
<qemu:arg value='device.ua-gfx0.x-width=16'/>
</qemu:commandline>
or, without an alias, set globals such as:
<qemu:commandline>
<qemu:arg value='-global'/>
<qemu:arg value='pcie-root-port.x-speed=8'/>
<qemu:arg value='-global'/>
<qemu:arg value='pcie-root-port.x-width=16'/>
</qemu:commandline>

Now that the downstream port will virtually negotiate itself to the
link status of the downstream device, we can remove this emulation.
It's not clear that it was every terribly useful anyway.

Change the default speed and width for new machine types to the
fastest and widest currently supported. This should be compatible to
the PCIe 4.0 spec. Pre-QEMU-4.0 machine types remain at 2.5GT/s, x1
width.

Support DMA read/write draining should be easy for existing VT-d
emulation since the emulation itself does not have any request queue
there so we don't need to do anything to flush the un-commited queue.
What we need to do is to declare the support.
These capabilities are required to pass Windows SVVP test program. It
is verified that when with parameters "x-aw-bits=48,caching-mode=off"
we can pass the Windows SVVP test with this patch applied. Otherwise
we'll fail with:
IOMMU[0] - DWD (DMA write draining) not supported
IOMMU[0] - DWD (DMA read draining) not supported
Segment 0 has no DMA remapping capable IOMMU units
However since these bits are not declared support for QEMU<=3.1, we'll
need a compatibility bit for it and we turn this on by default only
for QEMU>=4.0.
Please refer to VT-d spec 6.5.4 for more information.

When RSDP table was introduced (d4bec5d87), we calculated only legacy
checksum, and that was incorrect as it
- specified rev=2 and forgot about extended checksum.
- legacy checksum calculated on full table instead of the 1st 20 bytes
Fix it by adding extended checksum calculation and using correct
size for legacy checksum.
While at it use explicit constants to specify sub/full tables
sizes instead of relying on AcpiRsdpDescriptor size and fields offsets.
The follow up commits will convert this table to build_append_int_noprefix() API,
will use constants anyway and remove unused AcpiRsdpDescriptor structure.
Based on "[PATCH v5 05/24] hw: acpi: Implement XSDT support for RSDP"
by Samuel Ortiz, who did it right in his impl.

AcpiRsdpDescriptor describes revision 2 RSDP table so using sizeof(*rsdp)
for checksum calculation isn't correct since we are adding extra 16 bytes.
But acpi_data_push() zeroes out table, so just by luck we are summing up
exta zeros which still yelds correct checksum.
Fix it up by explicitly stating table size instead of using
pointer arithmetics on stucture.
PS:
Extra 16 bytes are still wasted, but droping them will break migration
for machines older than 2.3 due to size mismatch, for 2.3 and older it's
not an issue since they are using resizable memory regions (a1666142d)
for ACPI blobs. So keep wasting memory to avoid breaking old machines.

Instead of filling a mapped and packed C structure field in random order
and being careful about endianness and sizes, build_rsdp() now uses
build_append_int_noprefix() to compose RSDP table.
This makes reviewing and maintaining code easier as this is almost
matching 1:1 the ACPI spec itself.

We add the ability to build legacy or current RSDP tables, based on the
AcpiRsdpData revision field passed to build_rsdp().
Although arm/virt only uses RSDP v2, adding that capability to
build_rsdp will allow us to share the RSDP build code between ARM and x86.

Now that build_rsdp() supports building both legacy and current RSDP
tables, we can move it to a generic folder (hw/acpi) and have the i386
ACPI code reuse it in order to reduce code duplication.

The only remaining AcpiRsdpDescriptor users are the ACPI utils for the
BIOS table tests.
We remove that dependency and can thus remove the structure itself.

They've been deprecated for two releases and nobody complained that they
are still required anymore, so it's time to remove these now.
And while we're at it, mark the other remaining old 0.x machine types
as deprecated (since they can not properly be used for live-migration
anyway).

I'm working on fixing conflicts due to 29/30 and will include conflicting patch in my acpi tests cleanup on respin
Meanwhile could you drop 29/30 and apply the rest of pull request (which applies just fine)?

I can't apply a partial pull request -- MST will need to
drop those patches and send a v2.
