cb844ecd1d hypervisor: Add support for TDX exit reason to KVM
Relying on the recent additions to the kvm-ioctls crate, this commit
implements the support for providing the exit reason details to the
caller, which allows the identification of the type of hypercall that
was issued. It also introduces a way for the consumer to set the status
code that must be sent back to the guest.

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.

Fixes: #3658

658658e76c hypervisor: kvm: Ignore -EINVAL from KVM_KVMCLOCK_CTRL ioctl()
If the guest hasn't initialised a PV clock then the KVM_KVMCLOCK_CTRL
ioctl will return -EINVAL. Therefore if running in the firmware or an OS
that doesn't use the PV clock then we should ignore that error

Tested by migrating a VM that has not yet booted into the Linux kernel
(just in firmware) by specifying no disk image:

e.g. target/debug/cloud-hypervisor --kernel ~/workloads/hypervisor-fw --api-socket /tmp/api --serial tty --console off

Fixes: #3586

Update structure TdxInitVm to fit this change and avoid -EINVAL to be
returned by the kernel.

to the seccomp rules for live migration.
Adds necessary flags for MSHV.
This changes don't affect KVM functionality at all.

e7c9954dc1 hypervisor, vmm: Abstract the interfaces to start/stop dirty log
Following KVM interfaces, the `hypervisor` crate now provides interfaces
to start/stop the dirty pages logging on a per region basis, and asks
its users (e.g. the `vmm` crate) to iterate over the regions that needs
dirty pages log. MSHV only has a global control to start/stop dirty
pages log on all regions at once.

This patch refactors related APIs from the `hypervisor` crate to provide
a global control to start/stop dirty pages log (following MSHV's
behaviors), and keeps tracking the regions need dirty pages log for
KVM. It avoids leaking hypervisor-specific behaviors out of the
`hypervisor` crate.

1f2915bff0 vmm: hypervisor: split set_user_memory_region to two functions
Previously the same function was used to both create and remove regions.
This worked on KVM because it uses size 0 to indicate removal.

MSHV has two calls -- one for creation and one for removal. It also
requires having the size field available because it is not slot based.

Split set_user_memory_region to {create/remove}_user_memory_region. For
KVM they still use set_user_memory_region underneath, but for MSHV they
map to different functions.

This fixes user memory region removal on MSHV.

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.

Currently these two macros(msr, msr_data) reside both on kvm and mshv
module. Definition is same for both module. Moving them to arch/x86
module eliminates redundancy and makes more sense.

There are some code base and function which are purely KVM specific for
now and we don't have those supports in mshv at the moment but we have plan
for the future. We are doing a feature guard with KVM. For example, KVM has
mp_state, cpu clock support,  which we don't have for mshv. In order to build
those code we are making the code base for KVM specific compilation.
