=> sys_read => system_call_fastpath 2.2 通过TRACE_EVENT定义 trace event 内核或驱动模块可以定义自己的静态trace event。定义代码可以放在include/trace/events/或者驱动目录下。 在Kernel 4.14.74的典型运行时系统中,有1000+的trace event。 Trace Event是用include/linux/tracepoint.h提供的宏接口来定义的。宏...
While some networking functionality is placed in user space (e.g., route daemons), it is typically limited to slow-path and control plane processing. In contract, advanced packet processing functions require modification in the operating system kernel. These functions can be introduced either by ...
