research and development efficiency.Linux 4.0 Switchdev all bad messages end up in the Linux 4.0 kernel.Linux 4.0 introduces a Switchdev framework that represents the abstraction of a class of multi-port devices with "switching" capability chips. Each of these network ports is a port that is registered as a net_device in the Switchdev framework. In addition, the kernel comes with a rocker driver, demonstrating an actual device-driven implementation. The entire switchdev is as follows:Note that

programming in Linux.In general, the C/C ++ source code can be converted into executable files on the corresponding platform only after four steps: preprocessing, compilation, assembly, and connection. Most of the time, the programmer can complete the above four steps through a single command. For example, the following section C's "Hello world !" Code:File: HW. c# Include stdio. h>Int main (INT argc, char * argv []){Printf ("Hello world! /N ");Retur
solve the classification problem, according to some known training practice model, and then to predict the new data belong to which class. As shown in Figure 3, there are some two classes of data, the goal is to determine what kind of circle. In other words, the goal of logistic regression is to find a decision boundary that is good enough to distinguish the two classes well. Suppose that there is already such a boundary, which, in the case of this linear and measurable situation in the graph,

First, prefaceProcess switching is a complex process, and this article is not intended to describe in detail all aspects of the process switching, but rather to focus on a little bit of knowledge in process switching: the processing of TLB. To be able to articulate this problem, we describe in the second chapter some of the TLB-related details in a single CPU scenario, and the third chapter advances to the multi-core scenario, at which point the theoretical part ends. In the second chapter and t
