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 ...
Once the kernel has started, it starts the init process, [20] a daemon which then bootstraps the user space, for example by checking and mounting file systems, and starting up other processes. The init system is the first daemon to start (during booting) and the last daemon to terminate (during shutdown ).
Microsoft Structured Exception Handling is the native exception handling mechanism for Windows and a forerunner technology to Vectored Exception Handling (VEH). [1] It features the finally mechanism not present in standard C++ exceptions (but present in most imperative languages introduced later).
An oversimplification of how a kernel connects application software to the hardware of a computer. A kernel is a computer program at the core of a computer's operating system that always has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. [1]
The bootloader will load the kernel and initial root file system image into memory and then start the kernel, passing in the memory address of the image. At the end of its boot sequence, the kernel tries to determine the format of the image from its first few blocks of data, which can lead either to the initrd or initramfs scheme.
Automatic Memory Dump (Windows 8 and later) – same as Kernel memory dump, but if the paging file is both System Managed and too small to capture the Kernel memory dump, it will automatically increase the paging file to at least the size of RAM for four weeks, then reduce it to the smaller size.
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with the kernel. If a user now issues read/write/stat requests for this newly mounted file system, the kernel forwards these IO-requests to the handler and then sends the handler's response back to the user.
