Introduction Concurrent execution is an important concept in operating systems and kernel development. Modern processors can execute multiple tasks concurrently, often across multiple CPU cores. When
Introduction Priority inversion is a classic scheduling problem in real-time and concurrent systems. It occurs when a high-priority task is forced to wait for a lower-priority task, while a medium-pri
Introduction Priority inversion is a classic concurrency and real-time scheduling problem in operating systems. The basic situation is simple: A LOW-priority thread owns a mutex. A HIGH-priority thre
Synchronization is one of the most important concepts in Linux kernel development. When multiple kernel threads access a shared resource simultaneously, improper synchronization can lead to race condi
Deadlocks are one of the most common synchronization problems encountered in operating systems and concurrent programming. Although the concept is frequently introduced in textbooks, observing it insi
Memory and resource allocation are fundamental operations inside the Linux kernel. Whether assigning device IDs, managing CPU masks, allocating interrupt vectors, or tracking hardware resources, the k
