The UEFI Forum has announced the availability of the UEFI v2.6 and ACPI v6.1 specifications.
ACPI v6.1 includes:
* Interrupt-signaled events for expanded hardware-reduced platform support and improved system-on-chip designs.
* Standardized ARMv8-A processor support for “firmware-first” hardware error handling and reporting, including SEA and SEI notification types in the Hardware Error Source Table (HEST).
UEFI v2.6 includes:
* Enriched ability for agents in the system to provide better user interface support prior to launching of the OS through additional Image and Font information.
* Formal API definition for RAM Disk Protocol.
* New Wireless MAC Connection Protocol interface simplifies wireless network support and future radio technology versions.
* ARM error reporting extensions for the Common Platform Error Record (CPER), allowing ARMv8-A systems to implement “firmware-first” hardware error handling and reporting.
