==Arm SystemReady==
Arm SystemReady is a compliance program that helps ensure the interoperability of an operating system on Arm-based hardware from datacenter servers to industrial edge and IoT devices. The key building blocks of the program are the specifications for minimum hardware and firmware requirements that the operating systems and hypervisors can rely upon. These specifications are:<ref>{{cite web|url=https://www.arm.com/architecture/system-architectures/systemready-compliance-program|title=SystemReady Compliance Program|website=Arm}}</ref>

* Base System Architecture (BSA)<ref>{{cite web|url=https://developer.arm.com/documentation/den0094/latest|title=Arm Base System Architecture|website=Arm}}</ref> and the market segment specific supplements (e.g., Server BSA supplement)<ref>{{cite web|url=https://developer.arm.com/documentation/den0029/latest|title=Arm Server Base System Architecture|website=Arm}}</ref>
* Base Boot Requirements (BBR)<ref>{{cite web|url=https://developer.arm.com/documentation/den0044/latest|title=Arm Base Boot Requirements|website=Arm}}</ref> and Base Boot Security Requirements (BBSR)<ref>{{cite web|url=https://developer.arm.com/documentation/den0107/latest|title=Base Boot Security Requirements|website=Arm}}</ref>

These specifications are co-developed by [[Arm Holdings|Arm]] and its partners in the System Architecture Advisory Committee (SystemArchAC).

Architecture Compliance Suite (ACS) is the test tools that help to check the compliance of these specifications. The Arm SystemReady Requirements Specification documents the requirements of the certifications.<ref>{{cite web|url=https://developer.arm.com/documentation/den0109/latest|title=Arm SystemReady Requirements Specification|website=Arm}}</ref>

This program was introduced by [[Arm Holdings|Arm]] in 2020 at the first [[ARM DevSummit|DevSummit]] event. Its predecessor Arm ServerReady was introduced in 2018 at the Arm TechCon event. This program currently includes two bands:

* SystemReady Band: this band focuses on  operating system interoperability for Advanced Configuration and Power Interface [[ACPI]] environments, where generic operating systems can be installed on either new or old hardware without modification. This band is relevant for systems using [[Microsoft Windows|Windows]], [[Linux]], [[VMware]], and [[Berkeley Software Distribution|BSD]] environments.<ref>{{cite web|url=https://www.arm.com/architecture/system-architectures/systemready-compliance-program/systemready-band|title=Arm SystemReady Band|website=Arm}}</ref>
* SystemReady Devicetree Band: this band optimizes install and boot for embedded systems where [[device tree|devicetree]] is the preferred method of describing hardware, with a focus on forward compatibility. This applies to [[Linux]] distributions and [[Berkeley Software Distribution|BSD]] environments specifically.<ref>{{cite web|url=https://www.arm.com/architecture/system-architectures/systemready-compliance-program/systemready-devicetree-band|title=Arm SystemReady Devicetree Band|website=Arm}}</ref>
