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 kernel, and the LiteOS kernel.
The operating system was initially based on code from the Android Open Source Project (AOSP) and the Linux kernel; many Android apps can be sideloaded on HarmonyOS. [11] The next iteration of HarmonyOS was known as HarmonyOS NEXT. HarmonyOS NEXT was announced on August 4, 2023, and officially launched on October 22, 2024. [12]
This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade. [3] Another benefit of DKMS is that it allows the installation of a new driver on an existing system, running an arbitrary kernel version, without any need for manual compilation or precompiled packages provided by the vendor.
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.
After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. [8] Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...
A loadable kernel module (LKM) is an executable library that extends the capabilities of a running kernel, or so-called base kernel, of an operating system. LKMs are typically used to add support for new hardware (as device drivers ) and/or filesystems , or for adding system calls .
Linux kernel (<4.8.3) Dirty COW ( Dirty copy-on-write ) is a computer security vulnerability of the Linux kernel that affected all Linux-based operating systems, including Android devices, that used older versions of the Linux kernel created before 2018.
