Eclipse Foundation Oniro OS, or Oniro OS, is a family of open-source operating systems based on OpenHarmony from OpenAtom Foundation built for Internet of Things. [6] [7] [8]

Contents

Overview

Oniro OS supports various devices running on a RTOS-based Zephyr kernel with memory as small as 128 KB, or running on the bigger Linux Yocto kernel with memory greater than 128 MB and up on bigger devices. [9]

It is built on open-source HarmonyOS [10] called OpenHarmony distributed operating system built for Internet of things with a multi-layered architecture, which consists of four layers from the bottom to the top (kernel layer, system service layer, framework layer, and application layer).

Development

Applications for HarmonyOS are mostly built using components of ArkUI alongside cross-platform ArkUI-X variant, a Declarative User Interface framework. ArkUI elements are adaptable to various devices and include new interface rules with automatic updates along with HarmonyOS updates. [11]

Oniro OS is based on OpenHarmony, the open-source version of HarmonyOS [12] , and primarily uses App Pack files suffixed with .app (also known as APP files) for distribution of software via AppGallery. It also employs third-party distribution application stores on operating systems like the Linux-based Unity Operating System. Each App Pack contains one or more HarmonyOS Ability Packages (HAP) including code for their abilities, resources, libraries, and a JSON file with configuration information. [13]

The operating system utilizes the Linux Yocto kernel for bigger memory devices, as well as the RTOS-based Zephyr kernel for smaller memory-constrained devices in the Kernel Abstract Layer (KAL) subsystem. For webview applications, it incorporates the Servo browser engine at the system level for security. [14]

As a universal single IoT platform, Oniro OS allows developers to write apps once and run everywhere across devices such as phones, tablets, personal computers, TVs, cars, smartwatches, single board computers, and screenless IoT devices such as smart speakers. [15]

Software development

Downstream integration development, Eclipse Oniro currently bases its developments OpenHarmony on the latest release. Newer versions become targeted as they become available and used by the working group members. For Eclipse Oniro, a downstream OpenHarmony distribution, the primary focus is to ensure well-integrated and tested features. The downstream fork would hold all changes and would be tested by developers and CI for releases through the GitHub repo. OpenHarmony upstream integrates pull requests on the Gitee master branch.

A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are generally not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This line distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile unlike hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light-weight laptops, and the hybridization of the two in 2-in-1 PCs.

OpenAtom OpenHarmony, or abbreviated as OpenHarmony (OHOS), is a family of open-source operating systems based on HarmonyOS derived from LiteOS, donated the L0-L2 branch source code by Huawei to the OpenAtom Foundation. Similar to HarmonyOS, the open-source distributed operating system is designed with a layered architecture, which consists of four layers from the bottom to the top, i.e., the kernel layer, system service layer, framework layer, and application layer.

OpenAtom Foundation, a non-profit independent legal entity registered with the Ministry of Civil Affairs, is the first foundation for the open-source software in China. It was established in June 2020 and initiated jointly by Alibaba, Baidu, Huawei, Inspur, Qihoo 360, Tencent, China Merchants Bank and other companies for operation and marketing services of open source projects.

The HarmonyOS App Pack or the App file, identified with the file extension ".app", serves as the file format used by the HarmonyOS operating system. It functions as a native HarmonyOS app for distribution and installation through Huawei AppGallery, or for distribution through Huawei Ability Gallery in respect of installation-free apps under both current classic dual-framework and HarmonyOS NEXT system. The App file is also used by a number of other open source HarmonyOS-based operating systems such as OpenHarmony and Oniro OS-based operating systems for distribution and installation of applications, video games and middleware. Including non OpenHarmony-based operating systems, such as GNU Linux-based Unity Operating System that supports the app file format.

HarmonyOS NEXT is a proprietary distributed operating system and an iteration of HarmonyOS, developed by Huawei to support only HarmonyOS native apps. The operating system is primarily aimed at software and hardware developers that deal directly with Huawei. It does not include Android's AOSP core and is incompatible with Android applications.
