WrmOS [39] is a real-time operating system based on L4 microkernel. It has own implementations of kernel, standard libraries, and network stack, supporting ARM, SPARC, x86, and x86-64 architectures. There is the paravirtualized Linux kernel (w4linux [40]) working on WrmOS. Helios is a microkernel inspired by seL4. [41]
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 ...
While discarding the common Unix-like Linux kernel, HarmonyOS NEXT also replaces the previous multikernel system with its own HarmonyOS microkernel. [7] The rich execution environment (REE) version of HarmonyOS microkernel is placed at its core with a single framework as kernel mode.

A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.
The version history of the HarmonyOS distributed operating system began with the public release of the HarmonyOS 1.0 for Honor Vision smart TVs on August 9, 2019. The first expanded commercial version of the Embedded, IoT AI, Edge computing based operating system, HarmonyOS 2.0, was released on June 2, 2021, for phones, tablets, smartwatches, smart speakers, routers, and internet of things.
Several computer systems introduced in the 1960s, such as the IBM System/360, DEC PDP-6/PDP-10, the GE-600/Honeywell 6000 series, and the Burroughs B5000 series and B6500 series, support two CPU modes; a mode that grants full privileges to code running in that mode, and a mode that prevents direct access to input/output devices and some other hardware facilities to code running in that mode.
Kernel: resource allocation of memory, CPU time and interrupts; Kernel-mode processes including input/output (I/O) device drivers, file manager, swap manager, root process that connects the file manager to the disk (usually combined with the swap manager) Operating system supervisor; User processes
