6e101f479c vmm: Ensure hotplugged device identifier is unique 
Whenever a device (virtio, vfio, vfio-user or vdpa) is hotplugged, we
must verify the provided identifier is unique, otherwise we must return
an error.

Particularly, this will prevent issues with identifiers for serial,
console, IOAPIC, balloon, rng, watchdog, iommu and gpio since all of
these are hardcoded by the VMM.

e70bd069b3 vmm: Load kernel asynchronously 
Start loading the kernel as possible in the VM in a separate thread.
Whilst it is loading other work can be carried out such as initialising
the devices.

The biggest performance improvement is seen with a more complex set of
devices. If using e.g. four virtio-net devices then the time to start the
kernel improves by 20-30ms. With the simplest configuration the
improvement was of the order of 2-3ms.

fdeb4f7c46 Revert "vmm, openapi: Token Bucket fields should be uint64" 
This reverts commit 87eed369cd.

The reason we're reverting this is that OpenAPI Specification[0] doesn't
know how to deal with unsigned types. :-/

Right now the best to do is keep it as it's, as an int64, and try to fix
OpenAPI, or even switch to swagger, as the latter knows how to properly
deal with those.  However, switching to swagger is far from being an 1:1
transition and will require time to experiment, thus reverting this for
now seems the best approach.

Instead of defining some very generic resources as PioAddressRange or
MmioAddressRange for each PCI BAR, let's move to the new Resource type
PciBar in order to make things clearer. This allows the code for being
more readable, but also removes the need for hard assumptions about the
MMIO and PIO ranges. PioAddressRange and MmioAddressRange types can be
used to describe everything except PCI BARs. BARs are very special as
they can be relocated and have special information we want to carry
along with them.

5264d545dd pci, vmm: Extend PciDevice trait to support BAR relocation 
By adding a new method id() to the PciDevice trait, we allow the caller
to retrieve a unique identifier. This is used in the context of BAR
relocation to identify the device being relocated, so that we can update
the DeviceTree resources for all PCI devices (and not only
VirtioPciDevice).

7fd76eff05 vmm: Don't error if live resizing is not possible 
The introduction of a error if live resizing is not possible is a
regression compared to the original behaviour where the new size would
be stored in the config and reflected in the next boot. This behaviour
was also inconsistent with the effect of resizing with no VM booted.

Instead of generating an error allow the code to go ahead and update the
config so that the new size will be available upon the reboot.

2c8045343c vmm,cpu: Deny resizing only if the vcpu amount has changed 
188078467d made clear that resize should
only happen when dealing with a "dynamic" CpuManager.  Although this is
very much correct, it causes a regression on Kata Containers (and on any
other consumer of Cloud Hypervisor) in cases where a resize would be
triggered but the vCPUs values wouldn't be changed.

There's no doubt Kata Containers could do better and do not call a
resize in such situations, and that's something that should **also** be
solved there.  However, we should also work this around on Cloud
Hypervisor side as it introduces a regression with the current Kata
Containers code.

6b0df31e5d vmm: Add support for enabling AMX in vm guests 
AMX is an x86 extension adding hardware units for matrix
operations (int and float dot products). The goal of the extension is
to provide performance enhancements for these common operations.

On Linux, AMX requires requesting the permission from the kernel prior
to use. Guests wanting to make use of the feature need to have the
request made prior to starting the vm.

This change then adds the first --cpus features option amx that when
passed will enable AMX usage for guests (needs a 5.17+ kernel) or
exits with failure.

The activation is done in the CpuManager of the VMM thread as it
allows migration and snapshot/restore to work fairly painlessly for
AMX enabled workloads.

To solve this problem, move route.disable() before set_gsi_routes() to
remove the gsi from irqfds.items first.

This problem only exists on AMD platform, 'cause on Intel platform
kernel just return when update irte while it only prints a warning on
AMD.

Also, this patch adjusts the order of enable() and set_gsi_routes() in
unmask(), which should do no harm.

db9e5e5a87 vmm: interrupt: fix msi mask irq causing kernel panic on AMD 
When mask a msi irq, we set the entry.masked to be true, so kvm
hypervisor will not pass the gsi to kernel through KVM_SET_GSI_ROUTING
ioctl which update kvm->irq_routing. This will trigger kernel
panic on AMD platform when the gsi is the largest one in kernel
kvm->irqfds.items:

users to change that without any issue, as long as the VM has already
been created.

10676b74dc vmm: Split VM config and VM state for snapshot/restore 
In order to allow for human readable output for the VM configuration, we
pull it out of the snapshot, which becomes effectively the list of
states from the VM. The configuration is stored through a dedicated file
in JSON format (not including any binary output).

Having the ability to read and modify the VM configuration manually
between the snapshot and restore phases makes debugging easier, as well
as empowers users for extending the use cases relying on the
snapshot/restore feature.

507912385a vmm: Ensure that PIO and MMIO exits complete before pausing 
As per this kernel documentation:

      For KVM_EXIT_IO, KVM_EXIT_MMIO, KVM_EXIT_OSI, KVM_EXIT_PAPR, KVM_EXIT_XEN,
      KVM_EXIT_EPR, KVM_EXIT_X86_RDMSR and KVM_EXIT_X86_WRMSR the corresponding
      operations are complete (and guest state is consistent) only after userspace
      has re-entered the kernel with KVM_RUN.  The kernel side will first finish
      incomplete operations and then check for pending signals.

      The pending state of the operation is not preserved in state which is
      visible to userspace, thus userspace should ensure that the operation is
      completed before performing a live migration.  Userspace can re-enter the
      guest with an unmasked signal pending or with the immediate_exit field set
      to complete pending operations without allowing any further instructions
      to be executed.

Since we capture the state as part of the pause and override it as part
of the resume we must ensure the state is consistent otherwise we will
lose the results of the MMIO or PIO operation that caused the exit from
which we paused.

b3ca1d90e9 vmm: Stop dirty logging only if it has been started 
Now that we introduced a separate method to indicate when the migration
is started, both start_dirty_log() and stop_dirty_log() don't have to
carry an implicit meaning as they can focus entirely on the dirty log
being started or stopped.

For that reason, we can now safely move stop_dirty_log() to the code
section performing non-local migration. It makes only sense to stop
logging dirty pages if this has been started before.

a45e458c50 vm-migration: Add start_migration() to Migratable trait 
In order to clearly decouple when the migration is started compared to
when the dirty logging is started, we introduce a new method to the
Migratable trait. This clarifies the semantics as we don't end up using
start_dirty_log() for identifying when the migration has been started.
And similarly, we rely on the already existing complete_migration()
method to know when the migration has been ended.

A bug was reported when running a local migration with a vhost-user-net
device in server mode. The reason was because the migration_started
variable was never set to "true", since the start_dirty_log() function
was never invoked.

0dafd47a7c vmm: openapi: Remove mention to net fds 
While cloud-hypervisor does support receiving the file descriptors of a
tuntap device, advertising the fds structure via the openAPI can lead to
misinterpretations of what can and what should be done.

An unadvertised consumer will think that they could rather just set the
file descriptors there directly, or even pass them as a byte array.
However, the proper way to go in those cases would be actually sending
those via send_msg(), together with the request.

As hacking the openAPI auto-generated code to properly do this is not
*that* trivial, and as doing so during a `create VM` request is not
supported, we better not advertising those.

Please, for more details, also check:

ea0729c016 vmm: acpi: Create ACPI tables for TDX 
The way to create ACPI tables for TDX is different as each table must be
passed through the HOB. This means the XSDT table is not required since
the firmware will take care of creating it. Same for RSDP, this is
firmware responsibility to provide it to the guest.

That's why this patch creates a TDX dedicated function, returning a list
of Sdt objects, which will let the calling code copy the content of each
table through the HOB.

cdc14815be vmm: tdx: Only create ACPI tables if not running TDX 
In case of TDX, we don't want to create the ACPI tables the same way we
do for all the other use cases. That's because the ACPI tables don't
need to be written to guest memory at a specific address, instead they
are passed directly through the HOB.

4fda4ad6c9 arch, vmm: tdx: Remove TD_VMM_DATA mechanism 
It's been decided the ACPI tables will be passed to the firmware in a
different way, rather than using TD_VMM_DATA. Since TD_VMM_DATA was
introduced for this purpose, there's no reason to keep it in our
codebase.

Ensure all pending virtio activations (as triggered by MMIO write on the
vCPU threads leading to a barrier wait) are completed before pausing the
vCPUs as otherwise there will a deadlock with the VMM waiting for the
vCPU to acknowledge it's pause and the vCPU waiting for the VMM to
activate the device and release the barrier.

When in local migration mode send the FDs for the guest memory over the

cb15ae5462 vmm: openapi: Fix default value for tap 
`tap` has its default value set to `None`, but in the openapi yaml file
we've been setting it to `""`.

When using this code on the Kata Containers side we'd be hit by a non
expected behaviour of cloud-hypervisor, as even when using a different
method to initialise the `tuntap` device the code would be treated as if
using `--net tap` (which is a valid use-case).

50f5f43ae3 vmm: acpi: Make MBRD _CRS multi-segment aware 
Advertise the PCI MMIO config spaces here so that the MMIO config space
is correctly recognised.

Tested by: --platform num_pci_segments=1 or 16 hotplug NVMe vfio-user device
works correctly with hypervisor-fw & OVMF and direct kernel boot.

Fixes: #3432

e1c09b66ba vmm: Replace device tree value when restoring DeviceManager 
When restoring replace the internal value of the device tree rather than
replacing the Arc<Mutex<DeviceTree>> itself. This is fixes an issue
where the AddressManager has a copy of the the original
Arc<Mutex<DeviceTree>> from when the DeviceManager was created. The
original restore path only replaced the DeviceManager's version of the
Arc<Mutex<DeviceTree>>. Instead replace the contents of the
Arc<Mutex<DeviceTree>> so all users see the updated version.

a29e53e436 vmm: Move KVM clock saving to common Vm::restore() method 
Saving the KVM clock and restoring it is key for correct behaviour of
the VM when doing snapshot/restore or live migration. The clock is
restored to the KVM state as part of the Vm::resume() method prior to
that it must be extracted from the state object and stored for later use
by this method. This change simplifies the extraction and storage part
so that it is done in the same way for both snapshot/restore and live
migration.

2f8540da70 vmm: Rename PCI_MMIO_CONFIG_SIZE and move it to arch 
The constant `PCI_MMIO_CONFIG_SIZE` defined in `vmm/pci_segment.rs`
describes the MMIO configuation size for each PCI segment. However,
this name conflicts with the `PCI_MMCONFIG_SIZE` defined in `layout.rs`
in the `arch` crate, which describes the memory size of the PCI MMIO
configuration region.

Therefore, this commit renames the `PCI_MMIO_CONFIG_SIZE` to
`PCI_MMIO_CONFIG_SIZE_PER_SEGMENT` and moves this constant from `vmm`
crate to `arch` crate.

07bef815cc aarch64: Introduce struct PciSpaceInfo for FDT 
Currently, a tuple containing PCI space start address and PCI space
size is used to pass the PCI space information to the FDT creator.
In order to support the multiple PCI segment for FDT, more information
such as the PCI segment ID should be passed to the FDT creator. If we
still use a tuple to store these information, the code flexibility and
readablity will be harmed.

To address this issue, this commit replaces the tuple containing the
PCI space information to a structure `PciSpaceInfo` and uses a vector
of `PciSpaceInfo` to store PCI space information for each segment, so
that multiple PCI segment information can be passed to the FDT together.

Note that the scope of this commit will only contain the refactor of
original code, the actual multiple PCI segments support will be in
following series, and for now `--platform num_pci_segments` should only
be 1.
