The relationship between device and driver in linux driver development-Linux general technology-Linux programming and kernel information. The following is a detailed description. Yesterday I saw a piece of news titled "Housewives use LINUX". If we saw this news 10 years ago, we would be surprised to say, "I rely on it, housewives also use LINUX ", but now housewives use LINUX is not new to us because LINUX
Hyper-V Virtual Machine installation and nic cannot be found, driver cannot be installed Solution
I recently used a virtual machine in win2008 and encountered some problems during use. Now I have recorded the installation process and handling methods.
1. Install hyper-V. Right-click my computer and choose manage → Server Manager → role → add role on the right → select hyper-V for Installation
2. Choose "start"> "Management Tools"> "hyper-V ".
3. First
Before analyzing the driver, we will analyze the model of the IIC subsystem. There are 2 ways to IIC device drivers, one of which is to write user-driven through a universal driver. The other is to add a IIC device driver directly to the IIC subsystem, such as a driver for AT24C02.
Next we'll learn how to write a I
Knowledge Point analysis:Microsoft UAA (Microsoft Universal Audio Architecture) bus driver is Microsoft's system-level support driver for HD Audio standard HD Audio bus (High Definition Audio. The new HD Audio card driver and Modem driver are both developed based on the HD Audio bus.This problem does not occur if y
Buzzer driver source code in the/driver/char/buzzer/x210-buzzer.c file, the source code is as follows#include The driver module code for the buzzer is as above. As with other driver module code, the function in Module_init is the function that runs when the driver module is
Adding a driver to the android kernel is actually adding a driver to the Linux kernel. It mainly adds vertex information to two files, one is the kconfig file and the other is the MAKEFILE file. For example, if the driver you added is placed in the xxx directory under the DRIVERS directory, the kconfig and makefile files under the directory will be repaired.

between the device and the drive, through the platform bus, the device and the driver is separate registration, through the platform bus probe to detect and match the device at any time, such as matching on the device driver registration;C: Due to the above advantages, a driver can be used for several similar devices;3:platform Bus and platform bus device
Original unofficial Microsoft SQL Server Driver for PHP (sqlsrv)Here is unofficial modified builds of Microsoft ' s sqlsrv and pdo_sqlsrv drivers for PHP, version 3.0, for:

host, only one device can communicate with the host at the same time. Manage the external USB device via the USB host controller. USB controller is actually composed of USB controller hardware +USB Controller software. The USB host controller is divided into 3 kinds: UHCI, OHCI, EHCI. UHCI and OHCI Support USB1.1 protocol; EHCI supports USB2.0 protocol. UHCI, its hardware is simple, so the software is relatively complex, and OHCI, its hardware has more performance, contrary to the software to
One, what does the main device number and the secondary device number mean? Linu kernel is if the main device number to find the driver, the secondary device number to find the device.A: Usually a main device number represents a driver, for example, in a block device, a master device number represents a EMMC device, the different secondary device number represents a different partitionThe Linux kernel allow

B)You can either directly send a keyboard, mouse, or other message to the game process by determining that obstacles, monsters, and other things on the map have crossed the map. Of course, killing monsters is done by simulating buttons.
However, with the destructive impact of plug-ins on the game, anti-plug-ins and plug-ins have been entangled in the kernel layer, such:

The wince application was started two years ago. However, due to division of labor, there has never been a chance to gain a deep understanding of the development of the wince Driver (including Pb-related system customization ). If it weren't for the fakegps development work that was scheduled by Ma Ning some time ago, I really don't know when to understand the wince driver development.
Fakegps is a disguise

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.
Linux Device
1. Device Driver. In the Linux device model, the device driver is represented by the device_driver structure.
Struct device_driver {const char * Name;/* name */struct bus_type * bus;/* attached bus */struct module * owner; const struct of_device_id * of_match_table; INT (* probe) (struct device * Dev);/* call */INT (* remove) (struct device * Dev) when the device matches the
You know, drive life. Network card version of the new Realtek network card driver win10 version? Often heard that a small partner said that after the installation of the WIN10 system, the computer can not network. Even in the use of Driver Life Card version to install the network card driver is still unable to solve the problem.
Because the WIN10 system can use

(2) network device interface layer
(3) Device Driver Function Layer
(4) network device and media layer.
