cc96fc14b4 block: qcow: Implement dirty bit support for QCOW2 v3 images 
Add support for the dirty bit (bit 0 of incompatible_features) which
indicates the image was not closed cleanly. This improves data
integrity by allowing detection of potentially corrupted images.

On open:
- If dirty bit is already set, log a warning and trigger
  refcount rebuild
- Set the dirty bit and write it to disk immediately
- Sync to ensure persistence before any writes
- Skip dirty bit and refcount rebuild for readonly files

On clean close:
- Clear the dirty bit in the header
- Write it to disk and sync

7c99c169ba block: qcow: Validate incompatible feature bits 
Parse the feature name table header extension to provide descriptive
error messages when unsupported incompatible features are detected.
Currently only the compression bit (bit 3, zstd) is supported.

This prevents opening qcow2 images with features that would cause
incorrect behavior or data corruption (e.g., dirty bit, corrupt bit,
external data file, extended L2 entries).

Feature names are defined as follows:
1. The image's feature name table header extension (if present)
2. Hardcoded fallback names for known features
3. Generic "unknown feature bit N" for undefined features

Implement read support for bit 0 in QCOW2 L2 table entries.
When this flag is set, the cluster reads as zeros without accessing
disk. This improves compatibility with QCOW2 images that use this
optimization.

According to the QCOW2 specification, bit 0 of the standard cluster
descriptor indicates that the cluster reads as zeros. Unlike
l2_entry == 0 indicating a completely unallocated entry, bit 0 can
be set on an allocated cluster.

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.

cde7856d9e performance-metrics: Add warmup support for warm cache testing 
Add warmup_iterations field to run iterations before measuring
performance. This complements existing cold start tests
by separating cache effects from steady state throughput.

New tests with 2 warmup iterations:
- block_qcow2_backing_qcow2_read_warm_MiBps
- block_qcow2_backing_raw_read_warm_MiBps

Results show warm cache is much faster and more consistent:
- QCOW2: 1766 MiB/s (4% variance) vs cold 960 MiB/s (73% variance)
- RAW: 1822 MiB/s (6% variance) vs cold 1300 MiB/s (55% variance)

RAW backing is 3% faster than QCOW2 in steady state.

3fed706d6a block: qcow: Fix v3 header writing and add extension tests 
The write_to() function is used by test code to create qcow2 files for
testing. For v3 headers with extended header_size (>104), it needs to:

1. Write the mandatory compression_type field at bytes 104-111
2. Write the header extension end marker at the header_size offset
3. Seek to backing_file_offset before writing the backing file path

Additionally, create_for_size_and_path() must set backing_file_offset
to account for the 8 byte extension end marker in v3 files, so the
backing file path doesn't overwrite the extension area.

Add unit tests for read_header_extensions() covering backing format
parsing (raw/qcow2), unknown extensions, and error cases (invalid
formats, invalid UTF-8). These tests depend on the header writing fixes
to create properly formatted v3 test files.

9eb2b9b0e5 block: qcow: Implement extension parsing for QCOW v3 
Add support for parsing QCOW v3 header extensions to read the
backing file format. The QCOW v3 spec allows optional header
extensions between the fixed header and the backing file name.

Implement read_header_extensions() to parse the extension area,
which starts at the header_size offset. At the moment it is
used to read the backing file format. Further extension
processing is open in folow up implementations.

b3922dbd2c block: qcow: Add raw backing file support 
Add support for raw backing files in addition to qcow2 backing
files. This enables QCOW2 overlays to use raw images as their
backing store.

The backing file format is auto-detected when not specified,
using the existing detect_image_type() function.

Add backing_file_format field to QcowHeader to store the format
type, which will be populated from header extensions by a
subsequent patch.

Modify new_from_backing() to accept a backing_format parameter,
consolidating support for both raw and qcow2 backing files in a
single function. The backing_file_size parameter allows overlay
creation without opening the backing file multiple times.

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.

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])

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.
