Process state changesAfter the process has been created, the state may change a series of changes until the process exits. While there are several process states, the process state changes in only two directions-from the task_running state to a non-task_running state, or from a non-task_running state to a task_running state.That is, if a sigkill signal is sent to a task_interruptible state process, the process will first be awakened (into the task_running state) and then exited (into a task_dea

another process signal or clock interrupt,Enter the run queue. Linux uses task_interruptible macros to represent this state.Deep sleep State : It is basically similar to shallow sleep, but one thing is that no other process signal or clock interrupt wakes up. Linux using task_uninterruptibleThe macro represents this state.paused State : The process pauses execution to accept some sort of processing. If the process undergoing debugging is in this state,Linux uses the task_stopped macro to repre

These two differences are essentially the difference between pull poll and push push.Because of the essential difference between EDA and traditional SOA, it is now the birth of an area of EDA, which includes cqrseventsourc
