Run Windows 11 ARM64 guests on macOS over QEMU+HVF, with an ivshmem shared-memory transport carrying every guest channel (agent control, display/VDD, input, audio, clipboard, SSH, 9P) - no guest networking required. - tools/transport: one guest transport API, two backends (PC AF_HYPERV, Mac ivshmem); SPSC ring with an acquire-barrier fix for SSH integrity - tools/ivshmem: our own KMDF ivshmem BAR-mapping driver (no third party) - src/backend_mac: Mac-host ivshmem transport, QEMU VM lifecycle, IDD display consumer, agent/SSH proxies, ISO->disk patcher, Windows create - tools/agent + channel EXEs + tools/vdd: wired to asb_transport - tools/agent_win: staged guest payload (interim, pending JIT pull) - vendor/qemu-ivshmem: vendored QEMU 11.0.1 fork (ivshmem-plain) + LGPL source mirror for the self-contained app bundle - tools/sign/make-release.ps1: use the host-native ARM64 MSBuild so the WDK driver ApiValidator runs (the x86 validator fails on ARM64)

/*

|
* bcd_patch -- build a UEFI Windows-boot BCD store from the per-ISO BCD-Template.
|
|
*
|
|
* Reads \Windows\System32\config\BCD-Template (extracted fresh from the provided
|
|
* ISO's install.wim), and produces a working \EFI\Microsoft\Boot\BCD by:
|
|
* - overwriting {bootmgr}.23000003 (displayorder placeholder) -> the OS loader,
|
|
* - CREATING the device/osdevice/default/path elements that the template lacks
|
|
* (carved into a freshly appended hbin), pointing at our GPT partitions,
|
|
* - fixing the base-block sequence numbers + XOR checksum.
|
|
*
|
|
* No external dependencies. See docs/appsandbox/BCD-BUILD-SPEC.md for the
|
|
* regf + BCD-device-element layout this implements.
