90e50e67c6 conf: Introduce pstore device
The aim of pstore device is to provide a bit of NVRAM storage for
guest kernel to record oops/panic logs just before the it
crashes. Typical usage includes usage in combination with a
watchdog so that the logs can be inspected after the watchdog
rebooted the machine. While Linux kernel (and possibly Windows
too) support many backends, in QEMU there's just 'acpi-erst'
device so stick with that for now. The device must be attached to
a PCI bus and needs two additional values (well, corresponding
memory-backend-file needs them): size and path. Despite using
memory-backend-file this does NOT add any additional RAM to the
guest and thus I've decided to expose it as another device type
instead of memory model.

f13b3f8098 qemu: Filter firmware images by type
If the configuration explicitly requests a specific type of
firmware image, be it pflash or ROM, we should ignore all images
that are not of that type.

If no specific type has been requested, of course, any type is
considered a match and the selection will be based upon the

79941dd3c9 tests: Update firmware descriptors
Sync with the edk2-20240524-4.fc39 package from Fedora.

The only notable change is that the inteltdx variant now declares
support for Secure Boot and is a ROM image instead of a stateless
pflash one.

The latter causes it to be considered eligible for the
configuration described by the firmware-auto-efi-rw test cases,
which now passes instead of failing.

Of course that doesn't make any sense, because a ROM image by
definition cannot be read/write. So this indicates the presence
of a bug in our firmware selection algorithm, which we're going
to address with an upcoming commit.

70e826ec6a conf: Fix rawio/sgio checks for non-scsi hostdev devices
The current hostdev parsing logic sets rawio or sgio even if the hostdev type
is not 'scsi'. The rawio field in virDomainHostdevSubsysSCSI overlaps with
wwpn field in virDomainHostdevSubsysSCSIVHost, consequently setting a bogus
pointer value such as 0x1 or 0x2 from virDomainHostdevSubsysSCSIVHost's
point of view. This leads to a segmentation fault when it attempts to free
wwpn.

While setting sgio does not appear to crash, it shares the same flawed logic
as setting rawio.

Instead, we ensure these are set only after the hostdev type check succeeds.
This patch also adds two test cases to exercise both scenarios.

af437d2d64 qemu: Don't specify vfio-pci.ramfb when ramfb is false
Commit 7c8e606b64 attempted to fix
the specification of the ramfb property for vfio-pci devices, but it
failed when ramfb is explicitly set to 'off'. This is because only the
'vfio-pci-nohotplug' device supports the 'ramfb' property. Since we use
the base 'vfio-pci' device unless ramfb is enabled, attempting to set
the 'ramfb' parameter to 'off' this will result in an error like the
following:

  error: internal error: QEMU unexpectedly closed the monitor
  (vm='rhel'): 2024-06-06T04:43:22.896795Z qemu-kvm: -device
  {"driver":"vfio-pci","host":"0000:b1:00.4","id":"hostdev0","display":"on
  ","ramfb":false,"bus":"pci.7","addr":"0x0"}: Property 'vfio-pci.ramfb'
  not found.

This also more closely matches what is done for mdev devices.

TPM 1.2 is a pretty bad default these days, especially for

We're already carving out exceptions for several scenarios, but

exception.

Restructure the code so that it reflects reality and we don't
have to remember to update it every time a new architecture is

fa54595178 cpu_map: Drop 'mpx' from x86 cpu models
The mpx feature was removed from the corresponding qemu cpu models.
With mpx in the libvirt cpu models, libvirt believes the feature
to be implicitly enabled when creating qemu VMs, while in fact it is

This became an issue when commit 94eacd5a5f introduced new vmx-*
features, of which some are dependent on mpx (see "feature_dependencies"
table in qemu target/i386/cpu.c), e.g. vmx-exit-clear-bndcfgs and
vmx-entry-load-bndcfgs. These features cannot be enabled by qemu
without also mpx being enabled, leading to the error message

05c256f51a conf: Introduce @memReserve to <controller/>
There are PCI devices with pretty large non-prefetchable memory,
for instance:

  Memory at 9d800000 (64-bit, non-prefetchable) [size=8M]
  Memory at a6800000 (64-bit, non-prefetchable) [size=16K]

For cold plugged devices this is not a problem, because firmware
sets PCI controllers in a way that make devices behind them just
work. Problem arises if such PCI device is to be hot plugged.
Since the PCI device wasn't present at cold boot, firmware could
not take it into calculations and the amount of reserved memory
is not sufficient.

Introduce a know that allows users overriding value computed by
FW and thus allow hot plug of such PCI devices.

21af003084 qemu: enable display/ramfb for vfio pci hostdevs
Implement display="on" and ramfb="on" for vfio PCI host devices in qemu.
This enables passthrough PCI devices for display just like we did for
mdevs.

Rather than using 'virsh define' for the tests use the XML (or idea what
the XML is testing) and use them as 'qemuxmlconftest' cases.

c836887a02 qemu_command: Generate command line for MTP filesystem
The source tag sets the rootdir property of the device, which is
the directory exposed to the guest via the MTP device. The target
tag sets the desc property.  This device supports read-only mode
as well. Like virtiofs, it does not support additional access
modes.

317ac911f6 qemu: command: Remove fallback '-usb' handling
Currently all machine types which do honour '-usb' are already covered
by code which will either select a proper controller model or would
select the same one which '-usb' would use.

Thus all of the legacy -usb controller code can be removed.

a07544c0d7 qemu: command: Don't downgrade to '-usb' for arm based machines
- 'virt*' machines already don't allow downgrade
 - 'versatilepb' and 'realview' machines use 'pci-ohci' controller with '-usb'
 - all other machines ignore '-usb' (some have sysbus-based USB
   controller which we don't even consider)

For the 'versatilepb' and 'realview' machines libvirt would already
resort to picking either an existing controller model or trying to pick
the one which '-usb' would select and thus fail either way.

All other machine types ignore it.

We can thus remove the fallback for all arm-based machines.

5b136eba6d qemu: command: Don't downgrade to '-usb' for ppc based machines
- 'pseries' machines already don't allow downgrade
 - 'g3beige' and 'mac99' machines use 'pci-ohci' controller with '-usb'
 - all other machines ignore '-usb'

For 'g3beige' and 'mac99' libvirt already has 'pci-ohci' as contoller it
would select as one of the options when picking a model, thus it's
impossible to reach situation when '-usb' would be honoured.

All other machine types ignore it.

We can thus remove the fallback for all ppc-based machines.

5e84c6c1ce qemu: command: Don't downgrade to '-usb' with 'pseries' machines
The default USB device auto-selection code for 'pseries' machines picks
controller models which are also selected when '-usb' is used thus it's
impossible to end up in the case when using '-usb' would be possible:

 $ qemu-system-ppc64 --machine pseries,usb=on
 qemu-system-ppc64: could not find a module for type 'nec-usb-xhci'
 $ qemu-system-ppc64 --machine pseries-2.5,usb=on
 qemu-system-ppc64: could not find a module for type 'pci-ohci'

Remove the impossible downgrade and adjust tests.
