HarmonyOS Kernel (HongMeng Kernel), sometimes referred to as the Harmony kernel, is a computer operating system (OS) kernel developed by Huawei since August 2023. It is used in the HarmonyOS 5 version of the proprietary HarmonyOS distributed operating system, replacing previous versions that utilized the AOSP compatibility layer, the Linux ...
HarmonyOS is designed with a layered architecture, which consists of four layers; the kernel layer at the bottom provides the upper three layers, i.e., the system service layer, framework layer and application layer, with basic kernel capabilities, such as process and thread management, memory management, file system, network management, and ...
On August 4, 2023, at Huawei Developers Conference 2023 (HDC), Huawei officially announced HarmonyOS NEXT, the next version of HarmonyOS, supporting only native APP apps via Ark Compiler and native APIs in HarmonyOS SDK. [9] The kernel of HarmonyOS NEXT does not include the compatibility layer of AOSP framework with Android libraries from EMUI ...
While incorporating the OpenHarmony layer for running the APP files developed based on HarmonyOS APIs, the operating system utilizes the main Linux kernel for bigger memory devices, as well as the RTOS-based LiteOS kernel for smaller memory-constrained devices, as well as add-ons, custom kernels in distros in the Kernel Abstract Layer (KAL ...
The upgrade also improves layout, component, and app state management capabilities. [ 9 ] During HDC 2023, August 2023, Huawei announced HarmonyOS 4.0 improvements of ArkUI with ArkTS alongside native HarmonyOS NEXT software development using Ark Engine with ArkGraphics 2D and ArkGraphics 3D .
EulerOS is a commercial Linux distribution developed by Huawei based on Red Hat Enterprise Linux [2] to provide an operating system for server and cloud environments. [3] [4] Its open-source community version is known as openEuler; the source code of openEuler was released by Huawei at Gitee in 2020.
It reportedly supports different hardware architectures, with multiple POSIX standards which supports Linux kernel alongside its own RTOS kernel in its multikernel architecture and similar to OpenHarmony and HarmonyOS in distributed operating systems in terms of the Kernel Abstraction Layer.
EMUI 12 (2022) was the first EMUI version based on HarmonyOS 2 with a watered down OpenHarmony 2.1.0 [L3-L5] core branch variant on top of AOSP base which featured its own distributed file sharing called Distributed File System that adapted with HarmonyOS-powered smart devices with smart TVs, smart speakers and other types of devices which was ...
