Drop the generic type E and use IrqRoutngEntry directly. This allows
dropping a bunch of trait bounds from code.

There's no need to have the code creating the passthrough_device being
duplicated since we can factorize it in a function used in both cases
(both cold plugged and hot plugged devices VFIO devices).

Extend and use the existing DeviceTree to retrieve useful information
related to PCI devices. This removes the duplication with pci_devices
field which was internal to the DeviceManager.

Make the code a bit clearer by changing the naming of the structure
holding the list of IRQs reserved for PCI devices. It is also modified
into an array of 32 entries since we know this is the amount of PCI
slots that is supported.

We define a new enum in order to classify PCI device under virtio or
VFIO. This is a cleaner approach than using the Any trait, and
downcasting it to find the object back.

Introduces a tuple holding both information needed by pci_id_list and
pci_devices.
Changes pci_devices to be a BTreeMap of this new tuple.
Now that pci_devices holds the information needed from pci_id_list,
pci_id_list is no longer needed.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
In anticipation for further factorization, the pci_id_list is now a
hashmap of PCI b/d/f leading to each device name.

Instead of relying on a PCI specific device list, we use the DeviceTree
as a reference to determine if a device name is already in use or not.

This commit switches the default serial device from 16550 to the

On AArch64, interrupt controller (GIC) is emulated by KVM. VMM need to
set IRQ routing for devices, including legacy ones.
Before this commit, IRQ routing was only set for MSI. Legacy routing
entries of type KVM_IRQ_ROUTING_IRQCHIP were missing. That is way legacy
devices (like serial device ttyS0) does not work.
The setting of X86 IRQ routing entries are not impacted.

When booting with TDX no kernel is supplied as the TDFV is responsible
for loading the OS. The requirement to have the kernel is still
currently enforced at the validation entry point; this change merely
changes function prototypes and stored state to use Option<> to support.

When a vm is created with a pty device, on reboot the pty fd (sub
only) will only be associated with the vmm through the epoll event
loop. The fd being polled will have been closed due to the vm itself
dropping the pty files (and potentially reopening the fd index to a
different item making things quite confusing) and new pty fds will be
opened but not polled on for input.
This change creates a structure to encapsulate the information about
the pty fd (main File, sub File and the path to the sub File). On
reboot, a copy of the console and serial pty structs is then passed
down to the new Vm instance which will be used instead of creating a
new pty device.
This resolves the underlying issue from #2316.

Now that virtio-mem devices can update VFIO mappings through dedicated
handlers, let's provide them from the DeviceManager.
Important to note these handlers should either be provided to virtio-mem
devices or to the unique virtio-iommu device. This must be mutually
exclusive.
