This patch adds CPU frequency info extraction for board_inspector.
It is supposed to be used by ACRN CPU performance management.
Including those:
- Capabilities for HWP base regs, and turbo boost, by reading cpuids.
- Reporting all CPUID bits in LEAF 06H.
- Max none turbo ratio and max turbo ratio, by reading MSRs.
- HWP capabilities, by reading IA32_HWP_CAPABILITIES. Reading this
register requires HWP enabled in IA32_PM_ENABLE. (SDM Vol3 14.4.2:
Additional MSRs associated with HWP may only be accessed after HWP
is enabled)
- ACPI _PSD info, by reading sys nodes of Linux acpi-pstate driver.
This table describes frequency domains in which CPUs shares the same
frequency.

Supporting libraries of ACRN configuration toolset
This package contains the libraries supporting ACRN configuration toolset, including:
- The manipulators and validators of scenario schemas or XMLs
- The generator of guest ACPI tables
The main objective of this package is to ease the import of the supporting libraries in the ACRN configurator which uses a Python interpreter built in WebAssembly (WASM). This package is thus NOT intended to be used by users; invoke the Python scripts directly if needed.
