Overview

Arm SystemReady logo

Arm SystemReady is a compliance certification program based on a set of hardware and firmware standards. These standards include the Base System Architecture (BSA) and Base Boot Requirements (BBR) specifications, and market-specific supplements.

The SystemReady standards ensure Arm-based servers, infrastructure edge, and embedded IoT systems are designed to specific requirements, enabling generic off-the-shelf operating systems to ‘just work’. The term ‘just works’, means the process of enabling operating systems to work out of the box on Arm-based devices, through the adoption of these standards and tools. The compliance certification program tests and certifies that systems meet the SystemReady standards, giving confidence that operating systems and subsequent layers of software will just work, providing a seamless experience..

Arm SystemReady bands

There are four main bands of SystemReady: SystemReady SR, SystemReady ES, SystemReady IR, and SystemReady LS.

These bands all use the Base System Architecture (BSA) and the Base Boot Requirements (BBR) specifications, plus the relevant supplements such as the Server Base System Architecture (SBSA). We define the bands in consultation with our partners.

All SystemReady bands are supported by a common Architectural Compliance Suite (ACS) that is modular. The ACS enables testing against different combinations of specifications that are required by a SystemReady band. The Arm SystemReady Requirements (SRS) specification describes the certification requirements for each of the Arm SystemReady bands.

The following table shows the four bands of SystemReady and the relevant technical requirements for each band.

Pre-silicon compliance testing

Arm SystemReady pre-silicon compliance testing, based on the BSA specification, is available for silicon partners; Arm is working closely with EDA partners on developing tools for this. For silicon SoC manufacturers, each production run of a chip is costly. Pre-silicon compliance allows testing SoC designs before tape-out, to reduce cost and risk for our silicon partners.

SystemReady pre-silicon compliance benefits:

  • Provides BSA compliance before tape-out
  • Prevents costly silicon respins and software workarounds
  • Enables a well-defined and low-risk path to SystemReady

SystemReady Security Interface Extension

SystemReady Security Extension Logos

The Arm SystemReady security interface extension provides a way to certify that UEFI secure boot, secure firmware update, and TPM interfaces are implemented, as prescribed by the Arm Base Boot Security Requirements specification. The security interface extension can be followed alongside the SystemReady SR, ES and IR bands, or added on as a standalone if certification under these bands has already been achieved.

An Architectural Compliance Suite (ACS) is available to verify the compliance of a firmware implementation to BBSR. To assess the security robustness of architecture implementations in edge and IoT chips, system software, and devices, the PSA Certified program can be followed separately.
