Because anyhow version 1.0.46 has been yanked, let's move back to the
previous version 1.0.45.

This was causing some issues because of the use of 2 different versions
for the vm-memmory crate. We'll wait for all dependencies to be properly
resolved before we move to 0.7.0.
This reverts commit 76b6c62d07.

Instead of creating a MemoryManager from scratch, let's reuse the same
code path used by snapshot/restore, so that memory regions are created
identically to what they were on the source VM.

Move the definition of MSI space to layout.rs, so other crates can
reference it. Now it is needed by virtio-iommu.

Add a virtio-iommu node into FDT if iommu option is turned on. Now we

This commit implements the GIC (including both GICv3 and GICv3ITS)
Pausable trait. The pause of device manager will trigger a "pause"
of GIC, where we flush GIC pending tables and ITS tables to the
guest RAM.

The rust-vmm crates we're pulling from git have renamed their main
branches. We need to update the branch names we're giving to Cargo,
or people who don't have these dependencies cached will get errors
like this when trying to build:
error: failed to get `vm-fdt` as a dependency of package `arch v0.1.0 (/home/src/cloud-hypervisor/arch)`
Caused by:
failed to load source for dependency `vm-fdt`

Based on `--memory-zone` and `--numa` param in the Cloud Hypervisor
cmdline, the NUMA memory configuration is described. This commit
adds such NUMA memory configuration to the FDT memory node.
Signed-off-by: Henry Wang <Henry.Wang@arm.com>
For the purpose of identification, each NUMA node is associated
with a unique token known as a `numa-node-id`. For the purpose of
device tree binding, a `numa-node-id` is a 32-bit integer.
The CPU node is associated with a NUMA node by the presence of a
`numa-node-id` property which contains the node id of the device.

The optional device tree node distance-map describes the relative
distance (memory latency) between all NUMA nodes.

This is to make sure the NUMA node data structures can be accessed
both from the `vmm` crate and `arch` crate.

This doesn't really affect the build as we ship a Cargo.lock with fixed
versions in. However for clarity it makes sense to use fixed versions
throughout and let dependabot update them.

The Arm CPU topology is defined within the `cpu-map` node, which is
a direct child of the cpus node and provides a container where the
actual topology nodes are listed.
This commit adds an optional cpu-map node in device tree, based on
the Cloud Hypervisor command line vCPU topology information.

In an Arm system, the hierarchy of CPUs is defined through three
entities that are used to describe the layout of physical CPUs in
the system:
- cluster
- core
- thread
All these three entities have their own FDT node field. Therefore,
This commit adds an AArch64-specific helper to pass the config from
the Cloud Hypervisor command line to the `configure_system`, where
eventually the `create_fdt` is called.

To support different CPUID entry semantics, we now allow to
specify the compatible condition for each feature entry. Most entries
are considered compatible when they are "bitwise subset", with few
exceptions: 1. "equal", e.g. EBX/ECX/EDX of leaf `0x4000_0000` (KVM
CPUID SIGNATURE); 2. "smaller or equal as a number", e.g. EAX of leaf
`0x7` and leaf `0x4000_0000`;

We now send not only the 'VmConfig' at the 'Command::Config' step of
live migration, but also send the 'common CPUID'. In this way, we can
check the compatibility of CPUID features between the source and
destination VMs, and abort live migration early if needed.

This refactoring ensures all CPUID related operations are centralized in
`arch::x86_64` module, and exposes only two related public functions to
the vmm crate, e.g. `generate_common_cpuid` and `configure_vcpu`.

This patch fixes a few things to support TDVF correctly.
The HOB memory resources must contain EFI_RESOURCE_ATTRIBUTE_ENCRYPTED
attribute.
Any section with a base address within the already allocated guest RAM
must not be allocated.
The list of TD_HOB memory resources should contain both TempMem and
TdHob sections as well.

If GICR_CTLR is restored before GICR_PROPBASER and GICR_PENDBASER,
the restoring of the latter registers will fail, as the LPI enable
bit is already set in GICR_CTLR. Therefore, in this commit, the
order of restoring GICR registers is changed.
