task_state() –- returns state bitmask stored in state, such as TASK_RUNNING (0), TASK_INTERRUPTIBLE (1), TASK_UNINTTERRUPTIBLE (2). Last 2 values are for sleeping or waiting tasks –- the differe...
在PCI Express (PCIe) 中,struct resource结构体中的flag变量是用来标识资源的属性和状态的。具体来说,在 Linux 内核中,struct resource定义在<linux/ioport.h>头文件中,其中的flags字段是一个位掩码(bitmask),用于表示资源的一些特性。 这些特性包括: IORESOURCE_MEM: 表示资源是内存地址空间。 IORESOURCE_IO: 表示...

你定义的 RunMode 结构体似乎是用来表示不同的运行模式,通常这样的设计在需要多个状态或者视图(view)切换时很有用。你的代码中出现了一些语法错误,同时使用了位掩码(bitmask)来定义每个视图的模式。这种方式使得可以组合多种视图的

Linux 内核中 , 所有 进程管理 相关算法逻辑 , 都是基于task_struct结构体的 ; task_struct结构体在linux-5.6.18\include\linux\sched.h头文件中定义 , 第 629 ~ 1300 行就是struct task_struct结构体定义的代码 ; 二、task_struct 结构体代码示例 ...
