the nature of the problem. Football is my favorite sport, like to watch, but also like to play (although it has not played for a long time). There are four players in the football field--forwards, midfielders, defenders and goalkeepers--a team of 11. Usually a player appears only in one role, but he does not only work with the same partner, but also with other players to win the game. Each player should not only be aware of his role, but also understand the

conflict of views between the Linux community and Google's Android development team, however, the agreement was finally reached through negotiation. The above case shows that Google must obtain the approval from the maintenance manager of the main Linux kernel and register it when modifying the main "Linux kernel" to its own branch "android kernel, make "android kernel" part of "Linux kernel. Partially created in Middleware The development environment in the middleware layer mainly includes: (1

For details, see SWI under ads_{guide_d. 81st Q:Q: SWI menu?A: The SWI menu is determined by the SWI exception service program. It is often determined by the programmer. 82nd Q:Q: I used example 1 when porting your original code to UCOS, however, the Enable comms channel view and semihostin items are inactive when the processor's simulator mode is set according to Figure 7.17. w

The system environment is centos5.3 + jdk6 + tomcat6.0.20 + struts2.1.6 + spring2.5.6. Struts2 uses two plug-ins: struts2-convention-plugin-2.1.6.jar and struts2-spring-plugin-2.1.6.jar.

, which priority is the priority? What happens when a process has 2 priority levels?In fact, the Linux kernel has long been a solution.For the first question, which priority is more priority?The answer is that the real-time priority is higher than the nice value, and in the kernel, the real-time priority range is 0~max_rt_prio-1 Max_rt_prio definition see include/linux/sched.h1611 #define Max_user_rt_prio 1001612 #define Max_rt_prio Max_user_rt_prioThe nice value in the kernel

the nice value.So what if a couple of processes have the same two priorities at the same time?Priority, while the normal process corresponds to the nice value. In this case, there is no theory that a process has two different priority levels at the same time. Is that the truth? Repeat the above sentence: the process in Linux is divided into real-time processes and ordinary processes. Real-time processes correspond to real-time priorities. The normal process corresponds to the nice value. In thi

Use root to execute Sysinstall, and then select the Packages option in the Configure menu item, the system will display the corresponding menu options according to the different application categories, each of which corresponds to a class of application software, including all available applications. The software is also placed in the different storage subdirectories of the packages directory in the installation media, a

Now I will talk about the design schemes we adopt in eka2 and how they help us achieve our goals. 1.3.3 . 1 multi-thread preemptible Kernel To reduce the thread execution period, we designed eka2 to be multi-threaded, allowing low-priority kernel operations to be preemptible by high-priority kernel operations. Eka2 has five threads: 1. null thread -- idles CPU, and de-fragments Ram. This thread is also called idle thread 2. Manager thread-kill killed threads and processes (killed
