afc83582be aarch64: Enable IRQ routing for legacy devices
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.

acfbee5b7a interrupt: Make notifier function return Option<EventFd>
In anticipation for supporting the notifier function for the legacy

The reason is we can't return a reference when there's an Arc<Mutex<>>

1fc6d50f3e misc: Make Bus::write() return an Option<Arc<Barrier>>
This can be uses to indicate to the caller that it should wait on the
barrier before returning as there is some asynchronous activity
triggered by the write which requires the KVM exit to block until it's
completed.

This is useful for having vCPU thread wait for the VMM thread to proceed
to activate the virtio devices.

9dffc5da5c devices: ioapic: Always retrieve destination field on 8 bits
When the destination mode is physical, the destination field should
only be defined through bits 56-59, as defined in the IOAPIC spec. But
from the APIC specification, the APIC ID is always defined on 8 bits no
matter which destination mode is selected. That's why we always retrieve
the destination field based on bits 56-63.

ec56710c9b devices: ioapic: Mask entries by default
When created, the IOAPIC entries should be masked, as it is the guest's
responsibility (FW and/or OS) to unmask them if/when necessary.

This patch saves a full round of port I/O writes from the guest to the
IOAPIC, meant for masking the unmasked entries.

Because they're now masked, the entries are not enabled, which means
they are not connected from a KVM perspective, saving from unneeded
registration/unregistration of the irq fds.

This commit adds the implementation for the AArch64 PL031
Real Time Clock (RTC) that provides a long time base counter. This
is achieved by generating an interrupt signal after counting a

guest VM of the cloud-hypervisor will use this RTC to sync the time
in itself.

da2b3c92d3 vm-device: interrupt: Remove InterruptType dependencies and definitions
Having the InterruptManager trait depend on an InterruptType forces
implementations into supporting potentially very different kind of
interrupts from the same code base. What we're defining through the
current, interrupt type based create_group() method is a need for having
different interrupt managers for different kind of interrupts.

By associating the InterruptManager trait to an interrupt group
configuration type, we create a cleaner design to support that need as
we're basically saying that one interrupt manager should have the single
responsibility of supporting one kind of interrupt (defined through its
configuration).

We need to rely on the latest kvm-ioctls version to benefit from the

on the vmm-sys-util crate, using ">= 0.1.1" instead of being strictly
tied to "0.2.0".

Once the dependency conflict resolved, this commit took care of fixing
build issues caused by recent modification of kvm-ioctls relying on
EventFd reference instead of RawFd.
