Kernelkontext
Kernelkontext refers to the execution state of the operating system kernel on a processor when code runs with elevated privileges in kernel mode. It occurs during actions such as system calls, hardware interrupts, and other asynchronous events. The kernel context is distinct from user-space execution, where code runs with limited privileges and without direct access to kernel data structures.
There are two common kernel contexts. Process context describes code that executes on behalf of a user
To support multiple concurrent operations, kernels maintain per-CPU state for the kernel context, including registers, stack
Programming for kernel context requires careful synchronization and discipline. Access to shared data structures is protected
Understanding kernelkontext is essential for analyzing performance, latency, and correctness in an operating system, since context
