Access Control of Device Files: exclusive devices, restrict access by only one user (Single User Access) at a time, block user access, and copy the device when the device is turned on. Exclusive devices are mainly used to allow drivers to maintain a atomic_t variable. This variable is initialized to 1, indicating that it is available. When open is enabled, it is

In the above-mentioned Drive series blog, we have learned about blocking and non-blocking, asynchronous notification, polling, memory and I/O port access, concurrency control and other knowledge, the key device driver is relatively simple, this chapter content can deepen our character device driver architecture, blocking and non-blocking, Interrupt timer and other relevant knowledge of the understanding. In

After the crazy batch of a vendor's multimedia control app how rotten, bombast himself to do a minute thing. Of course, to do a very easy, more than their rotten software is still confident. The process encountered various pits, one of which was as followsJust start with a tablet to debug, always pop up the window to select the device, so tick "Use same device for the future launches", so eclipse by default

After sorting and digesting the device model, you have the foundation to compile a device driver program. You need to be familiar with the driver of the USB device because of the working relationship. Therefore, select the driver of the USB device as the start point. How can a USB

Transferred from: http://blog.csdn.net/thl789/article/details/6723350In the Linux 2.6 device-driven model, all devices are connected by bus. Device_register ()/Driver_register () executes the binding by enumerating the Driver/device on the bus, this article describes the process. This is the basis of the entire Linux device driver, platform devices, devices such

Under Windows System, any external device we can through the system to prohibit the use of it, users only need to properly take advantage of the Device Manager functions, you can make the specified device in a disabled state; users familiar with the Device Manager feature know that in

If you have multiple Android devices (including Android emulators) connected to your PC, you will need to use the Adb-s DeviceID shell when you enter the console. More trouble, this article has written a shell script file (need to be used under Linux or OS X, Windows needs to be newly written with bat or cmd).The basic idea is to use the ADB devices command to scan how many Android devices are connected to the PC, then intercept the device name from t

the unprecedented security threat. There are two security threats to IP network, one is the security of host (including user host and application server), and the other is the security of network itself (mainly network equipment, including routers, switches, etc.). The security threat perceived by a user host is primarily an attack on a particular operating system (primarily a Windows system), known as a virus. Network devices are mainly faced with the attack based on TCP/IP protocol. This pap
