UEFI and ACPI in Arm System Architecture

This session provides a comprehensive update on how UEFI and ACPI technologies are used in the Arm System Architecture from servers to edge and IoT devices. Arm standardizes on three major recipes for system firmware: 1) Standard Base Boot Requirements using UEFI, ACPI and SMBIOS interfaces to support the generic off-the-shelf operating systems with backward/forward portability when combined with Arm Base System Architecture hardware requirements; 2) Embedded Based Boot requirements using a reduced set of UEFI and Devicetree interfaces to support embedded Linux operating systems with standard UEFI interfaces for secure boot and OTA; 3) LinuxBoot Base Boot Requirements using ACPI, SMBIOS and a minimum set of UEFI runtime services to support some cloud provider’s Linux distros. Sample implementations, such as EDK2, UBoot, Coreboot, to these recipes will be discussed.
