This course is an in-depth explanation based on the first set of videos, which is an extension of the first set of courses.
WDM (Windows Driver Model) model is developed from WinNT3.51 and WinNT4 kernel mode device drivers. The main change of WDM is to add support for power management, Windows Management Interface (WMI), and device interface. The main goal of the WDM model is to achieve a more secure, flexible and simpler Windows device driver that can be used across platforms. WDM adopts the "object-based" technology and establishes a layered driver structure.
WDM was first implemented in Windows98 and further improved in Windows2000, and will exist in subsequent Windows operating systems, such as Windows Me and Windows XP, WINDOWS VISTA,WINDOWS 8,WINDOWS 8.1,WINDOWS 10。 Through the introduction of WDM model, Microsoft hopes to reduce the difficulty and cycle of device driver development and gradually standardize the development of device drivers. It should be said that WDM will become the mainstream of device drivers in the future.
This course starts from 0 to build a complete wdm driver, so that learners can understand the principles and functions of wdm design more clearly. The driver itself and inf files are more complex, but the spiral explanation makes the wdm driver more interesting and simple. There are pci, usb, serial ports and various pc hardware.
