UEFI 2.10 and ACPI 6.5 specifications released

The UEFI Forum released the UEFI 2.10 and ACPI 6.5 specifications on August 29. The new specification version expands support for new processor types, memory interfaces, and platform types while implementing post-quantum systems. Cryptographic Agility in Security.

UEFI (Unified Extensible Firmware Interface) refers to the Unified Extensible Firmware Interface, which is used to define the software interface between the personal computer operating system and the system firmware. The interface, everyone should have seen when installing the system.

ACPI (Advanced Configuration and Power Management Interface) refers to the advanced configuration and power management interface, which can help the operating system reasonably control and distribute the power of computer hardware devices.

The highlights of the UEFI 2.10 specification are as follows:

• Introduced UEFI conformance profile, allowing support for more types of platforms and implementation codebases
• Cryptographic agility, including SHA-384/SHA-512 signature schemes, support for Authenticated Variables
• Added support for LoongArch and RISC-V processor architectures
• Add confidential computing extension

Highlights of the ACPI 6.5 specification are as follows:

• Support CXL memory
• Supports LoongArch processor architecture
• Support for confidential computing event logs
• Support USB-C USB4

Mark Doran, Chairman of the UEFI Forum, said: "We are excited to share the new Conformance Profile feature in response to a request from the community. The Conformance Profile feature expands the types of platforms that UEFI can support to a wider range of platform types such as IoT, Embedded devices, and the automotive space, not just general purpose computers.”

At present, the LoongArch architecture has been supported by Linux, GO language, and GCC compiler. In addition, the SMBIOS specification has supported the LoongArch architecture. Since then, the basic hardware information developed based on the Dragon architecture platform will be displayed in a unified manner. The Dragon architecture has become another independent CPU instruction system supported by SMBIOS after x86, ARM, and RISC-V. Architecture.
