Blocks from different lines might overlap in time, which means several threads blocked on the resource at the same time. The Total line is special. It doesn’t belong to any specific thread, but contains all contentions of all threads on this resource ...
Kernel-levelthreads, which are threads managed and operated in the OS itself. It's the code involved in making the OS, not the user software applications, function. Kernel-level threads can be run to create and manage user-level threads, such as those used to launch and run user applicatio...
Multicore processors have become widely available, and single-threaded performance in new processors is likely to remain relatively flat. That means added pressure on software developers to improve application performance by taking better advantage of parallelism. ...
RT-Thread is very grateful for the support from all community developers, and if you have any ideas, suggestions or questions in the process of using RT-Thread, RT-Thread can be reached by the following means, and we are also updating RT-Thread in real time on these channels. At the sa...

For the purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of ...
Thread::interrupt调用os::interrupt方法实现,不同操作系统有不同的实现,以Linux系统为例。 代码语言:javascript 复制 // Linux系统interrupt方法实现如下:voidos::interrupt(Thread*thread){assert(Thread::current()==thread||Threads_lock->owned_by_self(),"possibility of dangling Thread pointer");//获取系统...
If the pool currently has more than corePoolSize threads, excess threads will be terminated if they have been idle for more than the keepAliveTime (seegetKeepAliveTime(TimeUnit)). This provides a means of reducing resource consumption when the pool is not being actively used. If the pool ...

在RT-Thread操作系统中定时器分为两种——硬件定时器和软件定时器。硬件定时器和软件定时器由两个链表分开管理。硬件定时器并非与真实物理硬件定时器1对1实现的,整个硬件定时器链表中的定时器都由OSTICK对应的定时器提供时钟源。软件定时器则由一个最高优先级(支持配置)的任务来提供时钟源。
