Linux Kernel Quick Guide Linux Kernel Quick Guide理解Linux内核是一项复杂而深刻的任务,因为它涉及到操作系统的核心功能。以下是对你提到的几个关键方面的详细解释: 进程调度: 调度器: Linux内核使用调度器来管理系统中运行的进程。CFS(完全公平调度器)是Linux中常用的调度器之一,它旨在实现对处理器的公平分配。 进程状态: 进程可以处于运行、就绪、阻塞等状态。调度器的任务是按照一定的算 2025-03-28 linux > kernel #3d #architect #boot #bpf #deb #debug #drivers #fs #gdb #go #gpu #java #kernel #kvm #linux #log #perf #performance #qemu #task #virt #mm #net #struct #proc #pthread #rcu #thread #sync #extern #mutex #security #container #irq #valgrind #tick #kms
