HongMeng Kernel (Chinese: 鸿蒙内核; pinyin: Hóngméng nèihé; lit. 'Hong Meng inner core') is a proprietary distributed operating system kernel developed by Huawei. It is used in current HarmonyOS 5 iterative versions of the HarmonyOS operating system, replacing previous versions that relied on the AOSP compatibility layer, Linux kernel, and LiteOS kernel. The HongMeng Kernel adopts a microkernel architecture, designed to enhance security by isolating critical system components while offering the ability to bring system components into the kernel for greater performance.
