The Real-Time Kernel 实时内核
Finally, I describe the real-time capabilities in the standard 2.6 kernel and show you how to enable and use them.
最后，描述了标准2.6内核的实时功能，并向您示范如何启用并使用这种功能。
The output displays the user time, kernel time, and real elapsed time.
输出显示用户时间、内核时间和实际流逝时间。
You can get soft real-time performance from the standard kernel or, with a little more work (kernel patch), you can build hard real-time applications.
从标准内核中您可以实现软实时功能，再执行一些额外的工作(内核补丁)您就可以构建硬实时应用程序。
