RT-Thread 自 v4.0.0 版本开始支持 SMP,在对称多核上可以通过使能 RT_USING_SMP 来开启。该文档主要对 SMP 进行介绍,以及讲解如何移植 RT-Thread SMP 。 多核启动 概述 系统上电后,每个CPU都会在 ROM 中的代码控制下独自运行,但是只有主处理器(以下简称 CPU0 )跳转到 RT-Thread 的初始化入口处,而其他的...

The scheduler policy of the thread is set to SCHED_FIFO with a default priority of 50. 在主线Linux中,中断服务例程在硬中断上下文中处理,硬件中断被禁用。硬件中断被禁用意味着抢占和软中断也被禁用。中断处理程序也在中断服务例程的上下文中处理,并且同样禁用硬中断。内核命令行选项 threadirqs 会将中断...
