Crate vck_loader 

vck-loader — UEFI loader framework for volumecrypt-kit.

This crate provides the loader-side mechanisms described in docs/architecture.md (“lib/loader”); the sample loader drives the flow itself and owns the crypto policy:

• init: start banner + enable the SSE/XMM control bits AES-NI needs.
• Block IO hooking engine (hook::BlockIoHookEngine): given a sample-built HookGeometry + VolumeCipher, hooks EFI_BLOCK_IO_PROTOCOL and EFI_BLOCK_IO2_PROTOCOL so that the OS volume data region is decrypted transparently while it is read during boot.
• Handover (handover): publishes the driver handover payload as a UEFI runtime variable (the driver reads it at OS runtime).
• Chainloading (chainload): loads and starts the next EFI image (the OS boot manager).

Full compilation targets a UEFI triple and requires the WEDK toolchain (G:\, see AGENTS.md); host builds are not expected.

Modules

chainload

Chainloading the next EFI image.

cpu

Loader-side CPU diagnostics and SSE/XMM enablement.

handover

Loader→driver handover (loader side).

hook

Block IO hooking engine.

provider

Loader-side shared types.

Functions

init

Loader initialization: emit a start banner and report/enable the SSE/XMM control bits required by AES-NI before any AES-NI code (cipher construction, the Block IO decrypt hook) runs. Call this first from the sample’s entry.
