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.”

In the world of DevOps there are ‘known good practices’ – aka ‘patterns’ – and ‘known bad practices’ – aka ‘anti-patterns.' Many of these patterns and anti-patterns have been developed from real world experience, especially by the early adopters of DevOps theory; but many are more feasible in theory than in practice, especially for more recent entrants to the DevOps scene. In this power panel at @DevOpsSummit at 18th Cloud Expo, moderated by DevOps Conference Chair Andi Mann, panelists will dis...

Up until last year, enterprises that were looking into cloud services usually undertook a long-term pilot with one of the large cloud providers, running test and dev workloads in the cloud. With cloud’s transition to mainstream adoption in 2015, and with enterprises migrating more and more workloads into the cloud and in between public and private environments, the single-provider approach must be revisited. In his session at 18th Cloud Expo, Yoav Mor, multi-cloud solution evangelist at Cloudy...

See storage differently! Storage performance problems have only gotten worse and harder to solve as applications have become largely virtualized and moved to a cloud-based infrastructure. Storage performance in a virtualized environment is not just about IOPS, it is about how well that potential performance is guaranteed to individual VMs for these apps as the number of VMs keep going up real time. In his session at 18th Cloud Expo, Dhiraj Sehgal, in product and marketing at Tintri, will discu...
