1. Generally, the driverProgramI/O requests should be processed asynchronously in the context of some unpredictable threads. We use the term arbitrary thread context to describe the context on which the driver does not know (or care about) the context of the current execution of the processor. 2. Windows 2000 uses the symmetric multi-processor model, that is, all the processors are the same, and system tasks and user-mode programs can be exe

Android system transplantation and driver development-Chapter 6-use instances to understand Linux driver development and experiences, and android driver development The operating method of the Linux driver is interaction. For example, if you want to send a print command to the Linux printer

To install a driver under Windows, we need to pack all the software you need-called a driver package. The driver package includes the general installation tools provided by the system for all device classes, and includes device-specific components provided by the device vendor. Let's take a look at what components are specifically needed in the

The MQ-2 Smoke gas sensor module is driven on the X210v3 Development Board.It is now necessary to drive a MQ-2 smoke gas sensor module. After detecting smoke exceeding a certain standard, it will return a different level, similar to the key driver.But when writing the driver, you need to use the Gph2_3 number PIN. However, the Ioremap address is then configured in the kernel, and it is not possible to control the GPIO or enter the interrupt.It was lat

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

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
