de2d8f486b hypervisor: mshv: Introduce CPU state update function and use it 
In most of the cases, special registers don't change after emulations,
but current code sets them back unconditionally, and although some of
them are set over the register page, others require a system call and a
hypervisor to be updated, which is a waste it there were not changes.

Introduce and CPU update method for Microsoft Hypervisor emulator and
set special registers only when they were changed. This change reduces
guest boot time by 4% for a single VP guest boot (in L1VH partition) in
my experiments.

5aba9b4308 hypervisor: emulator: Pass CPU context to instruction stream emulator 
This is a precursor change to overall ioctl and hypercall reduction
effort. The old (current) CPU state can be compared to the new to
determine what has changed and avoid unnecessary register updates.

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])

Demi Marie Obenour
2e05836669 hypervisor: Suppress unused_unsafe warning 
x86::__cpuid is safe on Rust ≥1.94 but unsafe on older versions.  This
causes unused_unsafe warnings when compiling with Rust ≥1.94.  However,
on earlier Rust versions, the code won’t compile if the unsafe blocks
are absent.

Work around this by adding #[allow(unused_unsafe)] where needed to
suppress the warnings.

See #7588 for more discussion.

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.

Introduce a new BlockControl struct to encapsulate fio operation
parameters. This replaces the tuple-based fio_control with a more
extensible structure that includes:
- fio_ops: The FIO operation type
- bandwidth: Whether to measure bandwidth or IOPS
- test_file: The file path to test against

This refactoring enables reusing performance_block_io with different
test files.

a8d1411307 vmm: Write directly to member when creating new devices 
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
vectors are unnecessary as we can directly write to the member of
`DeviceManager`.

4b4954ff86 hypervisor: AMX state snapshot and restore support 
The TILE data state of AMX may require 8KB+ space, calling the legacy
KVM_GET_XSAVE will encounter an error since KVM_GET_XSAVE only can get
4KB space. This patch adds KVM_GET_XSAVE2 support to allow snapping more
data.

Fixes: #7533

5c5f33050c block: qcow: Refactor pointer table writes to use iterators 
Refactor write_pointer_table to accept iterators instead of requiring
materialized vectors, eliminating temporary allocations in L1 table
sync operations.

Changes:
- Modified write_pointer_table() to take Iterator<Item = &T> and
  dereference internally before passing owned values to the callback
- Added write_pointer_table_direct() convenience wrapper for cases
  without value transformation
- Updated sync_caches() to use l1_table.iter() directly instead of
  .get_values().iter().copied()
- Implemented Deref<Target = [T]> for VecCache to enable direct .iter()

Performance impact:
- Eliminates L1 table allocation during sync (~2KB per 100GB disk)
- L2 and refcount table writes already used slices, no change there
- Zero performance overhead: iterator dereferencing is equivalent to
  .copied() and optimizes identically

The L1 sync previously collected entries into a Vec to apply the
OFLAG_COPIED flag. The new iterator+callback pattern computes this
on-the-fly, avoiding the allocation entirely.

be5b14ef3a block: qcow: Implement Deref for VecCache 
Add Deref<Target = [T]> implementation for VecCache<T> to allow direct
slice operations without explicitly calling get_values(). This enables
cleaner code patterns like cache.iter() instead
of cache.get_values().iter().

9dc923f379 seccomp: Allow fcntl in virtio-block thread 
Add fcntl to virtio_block_thread_rules to allow try_clone() on file
descriptors. The try_clone() method uses fcntl(fd, F_DUPFD_CLOEXEC)
to duplicate file descriptors, which is needed for efficient QCOW2
L1 table sync that avoids temporary allocations.

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.
