linux gui framework

Whether you're entertaining or working on Linux, this is a great opportunity for you to program with Python. Back in college I want them to teach me python instead of Java, which is interesting to learn and useful in practical applications such as Yum Package Manager. In this tutorial I'll take you through Python and a micro-framework called flask to build a simple application that displays useful informat

-directories, still, it's okay to create all the files in the/dev directory. Note that the input/USB/MISC subsystem only regulates the kernel device driver structure, which is transparent to user space. I feel that such normalization of the Linux kernel best reflects the truth of the computer industry, that is, "adding a Level". By introducing a new level, the Linux Kernel, without changing the original cha

implement datagram filtering (filter table), Network Address Translation (Nat table), and datagram processing (mangle table ). The three datagram processing functions provided by the Linux kernel are based on the netfilter hook function and IP table. They are independent modules and mutually independent. They are all perfectly integrated into the framework provided by Netfileter. Package filtering The filt

Compiling framework of Linux character Device Driver I. Concepts of Linux device driver A system call is an interface between the operating system kernel and applications, and a device driver is an interface between the operating system kernel and machine hardware. The device driver shields the application from hardware details. In this way, the hardware device

In this paper, we give a general Thread Pool Framework, the framework abstracts high-level tasks related to thread execution, making it irrelevant to specific execution tasks. In addition, the thread pool has dynamic scalability, it can automatically adjust the number of thread pool threads according to the severity of the task. At the end of the article, we'll give you a simple example program, and we'll s

This section describes the Linux Device Driver framework, driver configuration files, and common methods for loading drivers. It also describes how Red Hat Linux installer loads drivers, we can put the driver into the boot disk by ourselves; after installing the system, we can use kudzu to automatically configure the hardware program. 　　

, simplifying the type of data that needs to be passed , and passing the numberThe data is simplified. Otherwise, both the difficulty of implementation and the performance of the program can be difficult to improve. JNI still can't be wastedwe have seen the strength of JNA. How shabby the JNI is compared to it! However, there are some requirements that must be resorted to by JNI. JNA is a framework built on the basis of JNI technology. using JNI te

buffer into the request queue. 5. memory allocation and processingMemory processing This block is designed to be more personalized, allowing memory allocations to be customized and custom functions placed in a struct called v4l2_alloc_ctx. Its purpose is to provide videobuf with operational functions and to store some private data. Private data can be embedded in a larger number of structures. Struct Vb2_alloc_ctx {const struct VB2_MEM_OPS *mem_ops;}struct VB2_FOO_ALLOC_CONF {STRUCDT Vb2_

The maintainer of Mm_struct is a VMA linked list , where each VMA node corresponds to a contiguous process memory. The continuation here refers to continuous in the process space, no

algorithm (elevator algorithm). The elevator algorithm is completed at the I/O scheduling layer. The kernel provides different types of elevator algorithms, and the elevator algorithm has1 NoOp (Implement simple FIFO, basic direct Merge and sort),2 Anticipatory (delayed I/O requests, optimized ordering of critical sections),3 Deadline (improved for anticipatory disadvantage, reduced delay time),4 CFQ (Uniform allocation of I/O bandwidth, fairness mechanism)PS: In fact, the IO scheduling layer (

the frame sweep times. Such scheduling originates from the time required for the CRT's electronic gun deflection, but later becomes a de facto industry standard, so the TFT screen also contains the time to sweep back.Gives a map of the actual LCD display of a frame of data. The upper and lower bounds are the back sweep time of the frame switch, the left and right boundary are the sweep time of the row switching, and the horizontal and frame synchronization are the time required by the line and

packets at a particular point in the protocol stack, while Netpoll captures the packets directly above the NIC, even at the bottom of the protocol stack. Later, if you want to send a direct package in the kernel, no longer need to packet socket from the user state to start, construct a packet, directly through the Netpoll interface. The problem is that it uses the way the interrupt handler is manually triggered, and how efficiently is being tested. So this mechanism is best limited to debugging

In Linux input device keyboard, touch screen, mouse, etc. can be used in the input subsystem to achieve the drive. The input subsystem is divided into three layers, the core layer and the device driver layer. The event layer. The core layer and the event layer are implemented by the Linux input subsystem itself, and the device driver layer is implemented by us. We escalate the input event to the core layer
