In the notebook's desktop mode, tap the "device location" in the "Sidesync" software window.2. At this point the mobile device defaults to the right of the notebook device, as shown in the following figure:3. Click on the dropdown menu to choose your own position (take "top" for example). 4. Set to "Top", click "OK" be

In addition to network devices, character devices and block devices are mapped to file system files and directories through the file system's APIOpen (), close, write (), read (), and other accessible character devices and block devices.A block device is more complex than a character device, where a disk/flash file system, such as Ext3, is first created, and these filesThe system defines the organization of

Some time ago, I have been engaged in the application software of the GPS navigation system. Recently, it has come to an end. I continue to pick up the driver of the Linux device! The last time I recorded the module initialization code, I checked the code for uninstalling the module this time. Void scull_cleanup_module (void) Let's take a look at scull_trim. /*

desktops, virtual cloud desktops and the like.Therefore, for virtual cloud Desktop developers, the solution of remote access to local devices is also one of the basic and important issues.Look at an example that is unfamiliar to the average person and familiar to iOS developers,iOS app installation problem, very annoying, unlike Windows programs, as long as the development, can be copied everywhere, run everywhere.Self-developed app, need to deploy the Xcode development environment to the mobil

without policy include some typical features: simultaneous and asynchronous operations, the ability of drivers to be opened multiple times, the full use of hardware features, and the ability to "simplify tasks" or provide policy-related software layers.The driver is a software layer between the application and the actual hardware, the same hardware, and differen

From one point of view, the role of a device driver is to provide a mechanism, not a policy.When writing drivers, the program ape should pay particular attention to the following basic concept: When writing kernel code to access hardware, do not impose any specific policy on the user.

Using asynchronous notifications in device drivers can make access to the device accessible to the application by the driver when it is accessible. Therefore, applications that use nonblocking I/O do not need to poll the device for access, and blocking access can be superseded by asynchronous notifications like "break"

Android framework, Windows MFC, and Linux represent the software framework of the application layer. The problems that the application framework solves include application message processing, UI control display and processing, resource management, and so on. The benefit of the software framework is that the framework will do 80% of the development effort for you to solve a domain problem, and you only need

The Driver is also known as the Device Driver. In the modern computer architecture, the operating system does not directly deal with hardware, but communicates with hardware through drivers. On the same computer, although the devices are the same, the drivers vary greatly due to different operating systems. However, no matter what is similar, it can be summ

The previous article introduced the concept of Linux drive, and the basic classification of device drivers under Linux and the basis and difference of each classification, this article describes how to write a simple test driver like Hello World. and the only function of this driver is to output Hello world.Before writing a specific instance, let's take a look at

, struct file * filp) { Spin_lock ( singleuid_lock ); Singleuid_count --; Spin_unlock ( singleuid_lock ); Return 0; } We can see that the locks are used for operations on structures such as singleuid_count and singleuid_owner. Block-type open instead of ebusy: when the device is not accessible, it does not directly return ebusy, but is implemented by blocking I/O. Sample Code: Static int singleuid_count; Static uid_t singleuid_owner; Static spinlock_
