Core Viewpoint - Huawei's rotating chairman Xu Zhijun emphasized the progress and challenges of the HarmonyOS ecosystem during his keynote speech at the HarmonyOS Ecological Conference 2025, stating that while significant advancements have been made, the ecosystem is still in the introduction phase and has room for improvement [1][2]. Group 1: Progress in HarmonyOS Ecosystem - The head applications of the internet have adapted to HarmonyOS, and mid-tail applications are gradually joining, indicating that the ecosystem is fundamentally usable [1]. - A large number of SDKs across 21 categories, including security, media, and gaming, have been adapted to HarmonyOS, enhancing application development efficiency [1]. - Products equipped with HarmonyOS have demonstrated significant advantages in connectivity, speed, power consumption, smoothness, security, battery life, photography, and AI capabilities due to core technologies like distributed architecture, soft bus, microkernel, and native AI [1]. Group 2: Challenges and Call to Action - Despite the advancements, there are still gaps in achieving an "extreme" user experience, with some applications lacking "capillary-level" functionalities that could hinder user adoption [2]. - The high level of digital application penetration in China's mobile internet poses greater challenges for the development of the new ecosystem [2]. - Xu Zhijun called for developers to enhance the functionalities of HarmonyOS applications, encourage enterprises to adapt internal applications, and for existing Huawei smartphone users to upgrade to HarmonyOS to promote its advancement [2].

Investment Rating - The report does not explicitly provide an investment rating for the industry Core Insights - The report discusses two types of kernel architectures: microkernel and monolithic kernel, highlighting their respective advantages and disadvantages [3][4] - Monolithic kernels are known for faster processing speeds due to all components operating in the same address space, while microkernels are smaller and can fit into L1 cache [4][7] - The choice between microkernel and monolithic kernel often depends on the specific needs of the software development team and existing intellectual property [8] Summary by Sections Kernel Architecture Overview - The report outlines the characteristics of microkernels and monolithic kernels, emphasizing that the choice of kernel type is often influenced by operational needs and existing investments in intellectual property [3][8] Advantages of Monolithic Kernels - Monolithic kernels provide higher performance by reducing the number of abstraction layers, allowing for efficient communication between components [10] - They enable service access through a single system call without the need for inter-process communication, simplifying the design and reducing context-switching overhead [10] - Device drivers are more responsive and easier to manage as they run in the same address space as the kernel [10] Advantages of Microkernels - Microkernels are smaller and can adapt to system L1 cache, but they incur additional overhead due to the need for message passing between the kernel and user space [7] - The report notes that while microkernels have their benefits, the performance trade-offs may not align with the needs of all development teams [7][8]
