The os_sys_init_user function initializes and starts the Real-Time eXecutive (RTX) kernel. Use this function when you must specify a large stack for the starting task. The task argument points to the task function to start after the kernel is initialized
2.1.1 就绪列表初始化函数 OS_RdyListInit() (os_core.c) 初始化完成的事情: 遍历整个就绪列表,将各节点的头、尾指针清零。这些指针日后将用来存储 TCB 指针。 注意: 此函数不允许用户自己调用。 /* 初始化就绪列表 */voidOS_RdyListInit(void){OS_PRIO i;OS_RDY_LIST*p_rdy_list;for(i=0u;i<OS_...

文件/目录节点:对应于具体文件系统中的文件/目录,如/bin/init Vnode通过哈希以及LRU机制进行管理。当系统启动后,对文件或目录的访问会优先从哈希链表中查找Vnode缓存,若缓存没有命中,则并从对应文件系统中搜索目标文件或目录,创建并缓存对应的Vnode。当Vnode缓存数量达到上限时,将淘汰长时间未访问的Vnode,其中挂载点Vno...
