GPU Ring Buffer追踪架构深度分析:从blktrace到grtrace的设计演进 GPU Ring Buffer追踪架构深度分析:从blktrace到grtrace的设计演进摘要本报告基于对Linux内核源码的深度分析,系统性地研究了blktrace在磁盘IO子系统中的工作机制,以及ring buffer在GPU子系统中的核心作用。通过详细的代码分析、架构对比和性能评估,论证了ring buffer作为GPU追踪框架核心抽象层的必然性,并完整阐述了grtrace框架的设计理念与 2025-11-21 linux > drivers > gpu > grtrace > docs #3d #deb #debug #drivers #fs #go #gpu #kernel #linux #log #perf #task #virt #mm #struct #proc #rcu #sync #irq #grtrace
