Line 7:

The SBSA seeks to strengthen the ARM ecosystem by specifying a minimal set of standardized features so that an [[Operating_system|OS]] built for this standard platform should function correctly without modification on all hardware products compliant with the specification.

== Standardized Features ==

* CPU features

Line 17:

Existing specifications for USB, PCIe, ACPI, TPM, and other standards are incorporated to solidify the specification.

=== SBBR ===

Firmware issues are addressed separately in the Server Base Boot Requirements (SBBR) specification.

== Platform Validationvalidation ==

The Architecture Compliance Suite (ACS) checks whether an environment is compliant with the SBSA specification, and is provided under an Apache 2 open source license. It is available at https://github.com/ARM-software/sbsa-acs.

== LevelsCompliance of Compliancelevels ==

The specification defines levels of compliance, with level 0 being the most basic, and successive levels building on prior levels. In the words of the spec, "Unless explicitly stated, all specification items belonging to level N apply to levels greater than N."

Line 58 ⟶ 59:

Extends level 5, e.g. with support for speculative execution safety features.
