preempt in bridge

The problem of Vanilla kernel Linux kernel cannot be preempted in spinlock, IRQ contexts, so the time that a high-priority task wakes up to execution cannot be completely determined. Also, the Linux kernel itself does not handle priority inversion. Rt-preempt Patch is based on the Linux community kernel, plus the associated patches to make Linux meet hard needs. This article describes the practice of the patch on the PC. Our test environment is Ubunt

Without the steals protection lock __preempt_count, the code is unclear when it is appropriate to respond to rescheduling. Had to be passively postponed to after entry.

A bridge is a hardware device used to interconnect two or more data link layers (the second layer of the OSI seven-tier model) so that network devices on different network segments can access each other. When you want to interconnect multiple virtual machines or Ethernet interfaces in a host, you need to have a bridge-like concept in a Linux host. A soft bridge i

1. Bridge mode is very similar to strategy mode(in fact, a lot of design patterns are similar, because all the models are designed according to design principles , the principle of design is equivalent to the heart of martial arts, design mode is a move, as long as the heart is perfect, you can no recruit win a recruit .) )There is also a more detailed description of the strategy mode VS. Bridge mode ( draw

Design Mode (6) Bridge Connection Mode Bridge (Structural) 1. Overview In software systems, some types of software systems have two or more dimensional changes due to their own logic. How can we deal with such "multi-dimensional changes "? How can we use object-oriented technology to make this type easily change in multiple directions without introducing additional complexity? Example 1: Suppose we need

Speaking of the Yangtze River, my mind was impressed by the "Nanjing Yangtze River Bridge" in the elementary school text. Although the Yangtze River and the Yellow River have passed by for many times, but there is no chance to really witness and feel the two major rivers in China. The Yangtze River, the longest river in China, and the third largest river in the world. This trip to Wuhan is just as expected. First, go to the Yellow Crane Tower in Hang

Design Mode: bridge mode; design mode: Bridge Bridge, as the name suggests, builds a bridge between two objects that have a relationship. The two objects can be independent of each other, reducing coupling and solving the strong dependency between inheritance. For example, there are many electronic products, such as mo
