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]
The kerneloops software can collect and submit kernel oopses to a repository such as the www.kerneloops.org website, [7] which provides statistics and public access to reported oopses. A simplified crash screen was introduced in Linux 6.10, similar to the Blue Screen of Death on Windows. [8]
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 ...
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.
In embedded systems, a board support package (BSP) is the layer of software containing hardware-specific boot loaders, device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard), integrated with the embedded operating system.
Loadable kernel modules in Linux are loaded (and unloaded) by the modprobe command. They are located in /lib/modules or /usr/lib/modules and have had the extension .ko ("kernel object") since version 2.6 (previous versions used the .o extension). [5] The lsmod command lists the loaded kernel modules.
WSL 1 (released August 2, 2016), acted as a compatibility layer for running Linux binary executables (in ELF format) by implementing Linux system calls in the Windows kernel. [4] WSL 2 (announced May 2019 [5]), introduced a real Linux kernel – a managed virtual machine (via Hyper-V technology) that implements the full Linux kernel. As a ...
However, because of the design of the Windows kernel, Kernel Patch Protection cannot completely prevent kernel patching. [ 2 ] [ 3 ] This has led to criticism that since KPP is an imperfect defense, the problems caused to antivirus vendors outweigh the benefits because authors of malicious software will simply find ways around its defenses.
