A curated list of awesome things related to HarmonyOS

Ⅰ . What is HarmonyOS?

HarmonyOS is the first full-scene distributed OS based on microkernel. It is an operating system independently developed by Huawei. HarmonyOS System was officially released at the Huawei Developers Conference (<HDC.2019>) on August 9, 2019. Huawei will take the lead in deploying intelligent terminals such as smart screens, vehicle terminals and wearable terminals. In the future, more smart devices will be equipped with open source HarmonyOS than ever.

HarmonyOS achieves modular coupling, which corresponds to flexible deployment of different devices. HarmonyOS has three layers of architecture. The first layer is the core, the second layer is the basic services, and the third layer is the program framework. It can be used on a large screen, PC, automobile and other different equipment. It can also be used on mobile phones at any time, but for the time being, Huawei still prefers Android.

The underlying layer of HarmonyOS is composed of HarmonyOS microkernel, Linux kernel and Lite OS and it will become a complete HarmonyOS microkernel architecture in the future.

Ⅱ . Development process

Ⅲ . Features

HarmonyOS is designed to meet the high standard connection requirements of full-scene intelligent experience. For this reason, Huawei has proposed four system solutions with major features.

HarmonyOS's "Distributed OS Architecture" and "Distributed Soft Bus Technology" shield the application developers from the difficulties of implementing the underlying technologies of the corresponding distributed applications through the four capabilities of public communication platform, distributed data management, distributed capability scheduling and virtual peripherals, enabling developers to focus on their own business logic, like open. Developing cross-terminal distributed applications like the same terminal also enables the final consumers to enjoy the seamless experience brought by the powerful cross-terminal business collaboration capability for each use scenario.

HarmonyOS solves the problem of inadequate performance of existing systems by using two technologies: deterministic delay engine and high-performance IPC. Determining the delay engine can assign priority and time limit of task execution in the system before task execution. The priority task resources will give priority to scheduling, and the application response delay will be reduced by 25.7%. The compact structure of HarmonyOS microkernel greatly improves the performance of IPC (interprocess communication) and the efficiency of process communication is five times higher than that of existing systems.

HarmonyOS adopts a new micro-core design, which has stronger security features and low latency. The basic idea of microkernel design is to simplify the functions of the kernel, to realize as many system services as possible in user states outside the kernel, and to add security protection to each other. Microkernels only provide the most basic services, such as multi-process scheduling and multi-process communication.

HarmonyOS applies microkernel technology to Trusted Execution Environment(TEE), and reshapes trusted security through formal methods. A Formal method is an effective means to verify the correctness of the system and the absence of loopholes from the source by using mathematical methods. Traditional verification methods such as function verification and simulation attack can only be validated in limited scenarios, while formal methods can validate all software running paths through the data model. For the first time, HarmonyOS has applied formal methods to terminal TEE, which significantly improves the security level. At the same time, because the code amount of HarmonyOS microkernel is only one-thousandth of that of Linux macro-kernel, its attack probability is greatly reduced.

HarmonyOS relies on multi-terminal development IDE, multi-language unified compilation, distributed architecture Kit to provide screen layout control and interactive automatic adaptation, support control dragging, preview-oriented visual programming, so that developers can efficiently build multi-terminal automatic running App based on the same project, to achieve real one-time development, multi-terminal. Deployment to achieve shared ecology across devices. Huawei Ark Compiler is the first static compiler to replace the Android virtual machine model, which allows developers to compile high-level languages into machine code at one time in the development environment. In addition, the Ark Compiler will support multi-language unified compilation in the future, which can greatly improve the development efficiency.

HarmonyOS
What is this?This is a curated list of resources about HarmonyOS, the microkernel-based distributed operating system developed by Huawei. It aggregates official docs, architecture references, developer tools, drivers, books, and videos about the OS rather than being the OS itself.
Is this the actual operating system or just a list of links about it?It's just a curated list/index of links and resources about HarmonyOS — official sites, docs, SDKs, drivers, books, videos — not the OS source code or an installable package.
How is the list organized?It's organized into numbered sections: what HarmonyOS is, development history timeline, core features, and then resources split into official resources, downloads, architecture references, hardware drivers, developer tools (compiler/SDK/IDE), community, books, products, and videos.
Where should a beginner start?A newcomer should start with the 'What is HarmonyOS?' section explaining the distributed microkernel architecture, then move to the Official Resources and Documentation links for hands-on material.
Is this an official Huawei project?No — it explicitly states it's unofficial, just a collection of publicly available documents about HarmonyOS, not a commercial or Huawei-backed effort.
Who is this list useful for?It's aimed at developers and researchers curious about HarmonyOS's architecture, drivers, SDKs, and ecosystem, since it links to compiler tools, IDEs, driver kits, and technical documentation.
What makes HarmonyOS architecturally different from Android or Linux?HarmonyOS uses a microkernel design where the kernel code is only about one-thousandth the size of a Linux macro-kernel, reducing attack surface, and it uses a deterministic latency engine plus high-performance IPC (5x more efficient than existing systems) to cut application response delay by 25.7%.
What is distributed soft bus technology?It is the technology behind HarmonyOS's distributed architecture that shields developers from the complexity of cross-device communication, providing public communication, distributed data management, distributed capability scheduling, and virtual peripherals so apps can run seamlessly across multiple terminals.
When was HarmonyOS first announced and what was the first device to use it?HarmonyOS was officially unveiled by Huawei at HDC on August 9, 2019, and the Honor Smart Screen was the first product shipped with it.
What is the Huawei Ark Compiler mentioned in the resources?Ark Compiler is Huawei's static compiler designed to replace the Android virtual machine model, compiling high-level code directly to machine code; it is said to improve Android app runtime fluency by 24% and response speed by 44%.
What are similar projects?awesome-raspberry-pi, awesome-design-patterns, flash-linux0.11-talk, awesome-esp32, awesome-lowcode, architecture.of.internet-product, SwiftGuide, openwrt
