The Unified Extensible Firmware Interface (UEFI) Forum, a nonprofit industry standards body that promotes firmware innovations, today announced the publication of the Advanced Configuration and Power Interface (ACPI) Specification Version 5.1. This specification provides the interfaces needed to support the ARMv8-architecture in ACPI. It also maps out new features that are common to all supported platforms. These latest expansions further the UEFI Forum’s mission to ensure that the ACPI remains applicable to all systems and devices.
Also announced today is the availability of the ACPI Specification Version 5.0, Errata B. This document fixes minor errors and information gaps identified in the ACPI v5.0. Systems that have already been developed to comply with this version of the ACPI specification will benefit from these errata.
New Features, New Architectures: The ACPI 5.1 Specification
The ACPI is a robust interface between firmware, operating systems (OSes) and devices that provides management of hardware functions at runtime. The core ACPI-configurable functions include device discovery, thermal management, general UEFI boot capability, OS configuration and power management (OPSM) and reliability, availability and supportability (RAS) features. Use of the ACPI improves system power distribution and conservation.
The ACPI 5.1 specification is the first major document released by the UEFI Forum’s ACPI Specification Working Group (ASWG)—the committee responsible for the open standard since its October 2013 move under the Forum’s umbrella. In addition to extending the above-mentioned core ACPI functions to ARMv8-A architectures, the 5.1 specification introduces the following ARM 64-bit-focused features:
- Expanded Generic Interrupt Controller (GIC) Support: Extends ACPI support to include GICv2 virtualization, GIC v2m and parts of GICv3.
- Power State Coordination Interface (PSCI) Support: Allows PSCI discoverability via ARM Boot Flags filed in the Fixed ACPI Description Table (FADT).
- Always-On Timers and Watchdog: Ensures system memory mapped timers are compliant with ARMv7 and ARMv8 generic timer architecture.
“UEFI and ACPI are the prevalent open standards enabling flexible device configuration and power-state management in server class systems,” said Lakshmi Mandyam, director of server systems and ecosystems, ARM. “The ARMv8 server ecosystem is aligning around open industry standards with UEFI emerging as the boot model and ACPI as the runtime interfaces.”
New or enhanced features included in the 5.1 specification that benefit all ACPI-supported architectures include:
- Device-Specific Data (_DSD) Control: Reports device registry address location, generic clock controls and other critical properties to Linux OS-level drivers, allowing them to operate within the reported parameters.
- Collaborative Processor Performance Control (CPPC) extension: support platform-based, fully autonomous selection of performance states with OSPM providing information that guides the selection.
Additionally, the UEFI Forum is now responsible for assigning the Plug-and-Play (PNP) Identifiers and the ACPI Identifiers to avoid namespace collision.
“We kicked off ASWG in January. It is now the biggest Working Group in the UEFI Forum, with active participation from both x64 and ARM ecosystems, as well as the Windows and Linux communities,” said Dong Wei, UEFI Forum vice president and ASWG co-chair. “We worked together to update the ACPI Spec in record time—just over six months. With the latest ACPI v5.1 and UEFI v2.4, the industry has the opportunity to bring to market products based on converged platform infrastructure for interoperability while gaining more flexibility for innovations. Having this capability for both x64 and ARM architectures is a milestone achievement.”

The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, will compare the Jevons Paradox to modern-day enterprise IT, e...

Complete Internet of Things (IoT) embedded device security is not just about the device but involves the entire product’s identity, data and control integrity, and services traversing the cloud. A device can no longer be looked at as an island; it is a part of a system. In fact, given the cross-domain interactions enabled by IoT it could be a part of many systems. Also, depending on where the device is deployed, for example, in the office building versus a factory floor or oil field, security ha...

Fifty billion connected devices and still no winning protocols standards. HTTP, WebSockets, MQTT, and CoAP seem to be leading in the IoT protocol race at the moment but many more protocols are getting introduced on a regular basis. Each protocol has its pros and cons depending on the nature of the communications. Does there really need to be only one protocol to rule them all? Of course not. In his session at @ThingsExpo, Chris Matthieu, co-founder and CTO of Octoblu, walk you through how Oct...

If you’re responsible for an application that depends on the data or functionality of various IoT endpoints – either sensors or devices – your brand reputation depends on the security, reliability, and compliance of its many integrated parts. If your application fails to deliver the expected business results, your customers and partners won't care if that failure stems from the code you developed or from a component that you integrated. What can you do to ensure that the endpoints work as expect...

Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?
