a00189cf72 hypervisor: vmm: mshv: Enable SMT for guests with threads_per_core > 1 
Set HV_PARTITION_CREATION_FLAG_SMT_ENABLED_GUEST when the guest
topology has more than one thread per core. This allows the
hypervisor to schedule guest VPs correctly on SMT-enabled hosts.

Without this flag, the hypervisor schedules guest VPs incorrectly,
causing SMT unusable.

1e0eba60af vmm: always try THP for VM RAM 
The kernel allows madvise on shared memory if
/sys/kernel/mm/transparent_hugepage/shmem_enabled is set.
Always try and configure THP via madvise when
the user requests THP be enabled.
If this fails, only a warning log is emitted and THP won't be enabled.

2c2f5d2431 vmm: open backing file read-only when not shared 
When restoring from snapshot with shared=false, write access to the
backing file is not required. Opening it read-only allows restore to
succeed on read-only media and overlay lower layers while preserving
MAP_PRIVATE semantics.

28686bba46 vmm: fix rsdp_addr assertion for TDX 
TDX builds its own ACPI tables in `create_acpi_tables_tdx` so it will
return None in the standard `create_acpi_tables` function and the
assertion for `rsdp_addr` will fail.

c9cd82b52b vmm: fix CVM boot failure on MSHV 
Recent changes related to arm64 support in MSHV exposed
inconsistencies in the VM initialization and CVM boot paths.
The VM creation flow currently diverges across multiple scenarios,
including regular MSHV, CVM, and arm64, with each path performing
guest initialization steps in a different order.
Certain platform-specific requirements further constrain the ordering
of operations, such as the timing of address space creation,
IGVM loading, interrupt controller setup, and payload loading. For
CVM case address-space creation must be done after IGVM loading, and
PSP measurement. For Regular and arm64 this memory initialization
must be done early. For MSHV, vm.init() and sev_snp.init() are called in
different order which is run time and build time conditionally checked.

Additionally, while the KVM initialization path differs slightly
from MSHV, it shares common logic that is currently split across
separate conditional and build-time code paths, contributing to
fragmentation of the overall flow.

This change restructures the VM creation and initialization sequence
to better align shared logic, enforce scenario-specific ordering
constraints, and ensure consistent and correct behavior across all
supported configurations. In doing so, it restores proper CVM boot
behavior and improves the maintainability of the initialization code.

11edb28069 vmm: acpi: Clarify device ID partitioning in IORT table 
The IORT table's ID mapping uses a 256-ID offset per PCI segment to
ensure unique device IDs across all segments. This partitioning scheme
(output_base = 256 * segment_id) must match the device ID encoding used
in KVM MSI routing configuration [1].

This mapping assumes one bus per PCI segment, and supports up to 256 PCI
segments in the system.

01d711e893 vmm: acpi: Explicitly write ITS identifier in IORT table 
The IORT specification (Revision E.b, Table 12) defines the ITS Group
Node structure with an ITS Identifiers array following the node header.
Although the IORT table is zero-initialized, this commit adds an
explicit write of the ITS identifier value (0) for clarity and spec
compliance.

This ITS identifier must match the `translation_id` field in the MADT
GIC ITS structure to ensure proper interrupt routing on ARM platforms.

c87ca39219 vmm: acpi: Generate IORT table according to spec revision E.b 
The current IORT table implementation is based on IORT Spec revision E.b
[1], as evidenced by:
* The PCI root complex node revision being set to `3`
* The code being updated in late 2021 [2] when revision E.b was the
  latest version

This patch ensures the IORT table is properly generated according to
this specification revision, fixing three issues:

1. The IORT table revision should be `3` rather than `2` (see Table 2 in
   the spec [1])

2. The GIC ITS group node revision should be `1` rather than `0`
   (see Table 12 in the spec [1])

3. The "Memory access properties" and "ATS Attribute" fields of the PCI
   root complex node  was set incorrectly - specifically the MAF (Memory
   Access Flags) including CPM and DACS bits (see Tables 14, 15, and 17
   in the spec [1])

3657db7843 vmm: mshv: Set PROCESSORS_PER_SOCKET property for CPU topologies 
On MSHV, exposing multithreaded CPU topologies requires setting the
PROCESSORS_PER_SOCKET partition property so that CPUID.0xB reports
correct logical processor counts and topology levels to the guest.

This property must be set after all vCPUs are configured, as the
hypervisor uses the complete vCPU layout to derive and report CPU
topology information.

Virtio PCI devices are created in a set of nested functions. In each
of this functions a vector is created to add created devices to, only
to be appended to the vector of the higher nesting level. Those nested

6bda6541be vmm: cleanup &Mutex parameters 
In [0] we refactored some Arc<Mutex<T>> parameters to &Mutex<T>> to
satisfy clippy's needless_pass_by_value lint. Nevertheless, this is also
not so idiomatic, so as a follow-up, we put the responsibility to lock
objects to the caller side (only where this is not strictly needed by
the callee).

While on it, I also tried to pass vm_config directly into
pre_create_console_devices() which would clean up some code, but then
we have interleaving mutable and immutable borrows of the Vmm, which
are denied by the borrow checker.

dbb148b216 vmm: refactor live migration receive into state machine 
Previously, state that we accumulated during the migration process in
the receiver was kept in `mut Option` variables or HashMaps. The
problem is that it is unclear in the code when these variables can be
safely used. It's also difficult to add new state, such as the state
we need to handle the upcoming feature for performing the migration
using multiple connections.

To solve this, I've refactored the code to use the state machine
pattern. Each state carries the data it needs to. Any state that
didn't arrive yet (memory_files, memory_manager) cannot be accessed
until we are in the proper state.

Some benefits that fall out of this:

- We now respond to all requests, even invalid ones, at least with an
  error message.
- Any error handling a request will result in an error message being
  sent.
- There is only a single place where responses are sent and thus it's
  very hard to mess this up in the code.
- The main protocol state machine fits on a screen.

I would argue that especially the error cases are now much more
consistent. There is still a lot to be done. There is still state
transfer via self.vm and similar. In an ideal world, this would also
be carried by the state machine. I also want to see better handling of

is already too big. :)

... and nuke some Option<> while I was there. Given that HashMap has a

c53781bf5f misc: clippy: add needless_pass_by_value 
This is a follow-up of [0].

# Advantages

- This saves dozens of unneeded clone()s across the whole code base
- Makes it much easier to reason about how parameters are used
  (often we passed owned Arc/Rc versions without actually needing
  ownership)

# Exceptions

For certain code paths, the alternatives would require awkward or overly
complex code, and in some cases the functions are the logical owners of
the values they take. In those cases, I've added
#[allow(clippy::needless_pass_by_value)].

This does not mean that one should not improve this in the future.

ac5fc69b2e vmm: Fix fd leak in socket connection handling 
Previously, `into_raw_fd()` transferred fd ownership to epoll while
keeping separate clones in `reader` and `writer`, causing leaks when
the stream was closed. Now, `reader` owns the fd and epoll borrows it.
When the FD is closed in the kernel, reader will be reset to None.

41382879d3 seccomp: add arch_prctl syscall for amx 
When enabling amx feature, we should call arch_prctl to request
permission to use tile data for guest. The permission should be
requested before the first vcpu is created, so we need to call
arch_prctl in vmm thread. This patch adds the arch_prctl syscall for
vmm_thread_rules.

Fixes: #7516

6a86c157af misc: clippy: add needless_pass_by_value (partially) 
This helps to uncover expensive and needless clones in the code base.
For example, I prevented extensive clones in the snapshot path where
(nested) BTreeMap's have been cloned over and over again. Further,
the lint helps devs to much better reason about the ownership of
parameters.

All of these changes have been done manually with the necessary
caution. A few structs that are cheap to clone are now `copy` so that
this lint won't trigger for them.

I didn't enable the lint so far as it is a massive rabbit hole and
needs much more fixes. Nevertheless, it is very useful.

It takes a pointer to a userspace address that it accesses, so it should
be marked unsafe.  This was missed earlier.

8be28f8438 misc: Work around vfio_dma_map being unsound 
This API passes a u64 to a kernel API that treats the u64 as a userspace
address.  Therefore, it should be marked unsafe, but it currently is not
[1].  Wrap the call in an unsafe block to document that invariants must
be upheld to avoid undefined behavior.  This causes a compiler warning,
so suppress the warning with #[allow(unused_unsafe)].

199d2d05d8 hypervisor: tdx: do not use u64 to represent pointers 
Also drop support for building the TDX code for 32-bit targets.  All
CPUs with TDX support are 64-bit so supporting 32-bit targets is not
needed.

42522a88c0 misc: do not use u64 to represent host pointers 
To ensure that struct sizes are the same on 32-bit and 64-bit, various
kernel APIs use __u64 (Rust u64) to represent userspace pointers.
Userspace is expected to cast pointers to __u64 before passing them to
the kernel, and cast kernel-provided __u64 to a pointer before using
them.  However, various safe APIs in Cloud Hypervisor took
caller-provided u64 values and passed them to syscalls that interpret
them as userspace addresses.  Therefore, passing bad u64 values would
cause memory disclosure or corruption.

Fix the bug by using usize and pointer types as appropriate.  To make
soundness of the code easier to reason about, the PCI code gains a new
MmapRegion abstraction that ensures the validity of pointers.  The rest
of the code already has an MmapRegion abstraction it can use.  To avoid
having to reason about whether something is keeping the MmapRegion
alive, reference counting is added.  MmapRegion cannot hold references
to other objects, so the reference counting cannot introduce cycles.
