This article is based on the protocol stack 1.3.2, please respect the originalGeneral Introduction :Osal provides a timer that can function with a callback function, which is implemented mainly in the OSAL_CTIMER.C and osal_cbtimer.h two files. The callback timer is a callback function registered on the basis of the Osal software timer, which executes the pre-reg

The last section of kernel time management men

TIMERFD is a timer interface provided by Linux for the user program. This interface is based on file descriptors, and can be used for select/poll scenarios by using the file descriptor's readable event for timeout notification.One, related operation function#include int timerfd_create (int clockid, int flags);int timerfd_settime (int FD, int flags, const struct ITIMERSPEC * new_value, struct itimerspec *old_value);int timerfd_gettime (int fd,

I've been looking at some of the JavaScript principles, and I happen to see an analysis of the author of jquery about the principle of the JavaScript timer, so I decided to translate the original into Chinese, to share with you, and secondly, to deepen your understanding of JavaScript. Original link: http://ejohn.org/blog/how-javascript-timers-work/Original translation:At the basic level, it is important to understand how JavaScript timers work. Becau

the soft interrupts for all registrations under kernel. struct softirq_action{void (*action) (struct softirq_action *);}; The array subscript represents the soft interrupt number, and the softirq_action represents the soft interrupt handler function. The Softirq_vec is similar to irq_desc that characterize hardware interrupts under kernel. /* Please, avoid to allocate new SOFTIRQS, if you need not _really_ high frequency threaded job scheduling. For almost all the purposes tasklets is more than

Timers typically play an important role, whether in client applications or server components, including window services. Writing an efficient timer-driven manageable code requires a clear understanding and mastery of the program flow. The subtlety of the net threading model. NET Framework class library provides three different timer classes: System.Windows.Forms.Timer, System.Timers.Timer, and System.Thread

This article was reproduced from: http://blog.csdn.net/dean_gdp/article/details/25481225Basic operation of HrtimerThe traditional Linux timer is implemented by the time-wheel algorithm (TIMER.C), but Hrtimer is implemented by the red-black tree algorithm. In struct Hrtimer There is a node field, which is a struct rb_node, which represents the position of hrtimer in a red-black tree.Hrtimer_startThe Hrtimer_start function adds a hrtimer to a red-black

PWM Timer TIMER0 Learning notes: First, the timer TIMER0 code used in the register. What these register functions are. What is the meaning of the bits involved in the initialization of these registers. : TCFG0 function is: Timer configuration register, you can set the first Prescaler frequency and the second prescaler frequency of the prescaler frequency factor

From: http://blog.163.com/hong_nt/blog/static/10468917120081130103632925/ The main function of the software timer is to implement the timeout mechanism of the state machine and implement the timeout-based counting function.Because the Protocol state machine runs on the Linux kernel, that is, it runs on the user State. InIn Linux, user-Mode Applications can only call three Timers: itimer_real, itimer_virtual, and itimer_prof. In the Protocol state mac
