848d88c122 aarch64: Reserve a hole in 32-bit space
The reserved space is for devices.
Some devices (like TPM) require arbitrary addresses close to 4GiB.

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.

3c973fa7ce virtio-devices: vhost-user: Add support for TDX
By enabling the VIRTIO feature VIRTIO_F_IOMMU_PLATFORM for all
vhost-user devices when needed, we force the guest to use the DMA API,
making these devices compatible with TDX. By using DMA API, the guest
triggers the TDX codepath to share some of the guest memory, in
particular the virtqueues and associated buffers so that the VMM and
vhost-user backends/processes can access this memory.

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

Also, this patch adjusts the order of enable() and set_gsi_routes() in

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.

885dce4082 deps: Move to latest vm-virtio and vhost-user-backend releases
Move to release version v0.2.0 for both vm-virtio and vhost-user-backend
crates rather than relying on their main branch, as they might be
subject to breaking changes.

Fixes #3800

4cf22e4ec7 arch: do not hardcode MMIO region length in MmioDeviceInfo
Add a field for its length and fix up users.

Things work just because all hardcoded values agree with each other.
This is prone to breakage.

No functional change.
