UEFI 2.10 and ACPI 6.5 specifications released

by ·

UEFI is the Unified Extensible Firmware Interface, which was developed based on the EFI 1.10 standard and is owned by an international organization called the UEFI Forum. UEFI is a standard that specifies the type of interface that allows a PC to load into an operating system from a pre-boot operating environment. ACPI is the Advanced Configuration and Power Management Interface, which is a mechanism that allows the operating system to control power management and device configuration.

The UEFI Forum announced today the release of the UEFI 2.10 specification and the ACPI 6.5 specification. The new specification version extends support for new processor types, memory interfaces, and platform types while enabling cryptographic agility in post-quantum system security.

“We are excited to share the new Conformance Profiles feature, responsive to community pull for a way to make the UEFI Forum’s work useful,” said Mark Doran, UEFI Forum President. “The Conformance Profiles feature will expand the platform types UEFI can support to an ever wider range of platform types like IoT, embedded and automotive spaces – beyond general purpose computers.”

UEFI 2.10 Specification Highlights:

  • Introducing UEFI Conformance Profiles, allowing support for more types of platforms and implementation codebases
  • Crypto agility including SHA-384/SHA-512 signing scheme for Authenticated Variables support
  • Emerging LoongArch and RISC-V processor architecture support
  • Add confidential computing extension

ACPI 6.5 Specification Highlights:

  • CXL Memory support
  • LoongArch processor architecture support
  • Confidential Computing event log support
  • USB-C USB4 support
