Mirror driver mirroring Drive, directly create a virtual graphics driver (personally think), the application calls the operating system needs to change the graphics display in advance intercept the application needs to display the area and content, and buffer into memory. Comparing the methods that capture the screen in real time and compare differences has the following advantages:1, CPU occupancy rate is small, generally under 5%, real-time high2, do not need to compare differences, because th

Here we mainly talk about the overall structure of the USB driver protocol stack in Windows XP and some important internal data structures. When writing these things, I referred to the related forum posts of Daniel Tiamo. The content is similar and I can't say that it is a repost. The USB protocol stack consists of the following driver files: the USB port. sys USB Host Controller shares the driver code library for The miniport driver to call. USB hub.

1. D3d runtime and DX graphics core subsystem have done more work, including management of memory and DMA. 2. It is easier to create a surface. Previously, 1). ddcancreatesurface 2). ddcreatesurface 3). d3dcreatesurfaceex; the first two are both core mode methods. Now you only need createresource. 3. Surface: Create, destroy; and lock and unlock pairs. (What does Shenma mean? Isn't this a feature in the past ?) 4. Video memory, memory, and hosted surface are treated eq

I recently learned storport miniport driver. When I saw interrupt, I found two methods: one is to respond through the hwinterrupt function in hw_initialization_data (storport, line-based interrupts and message-based interrupts are supported. The other is to respond through hwmsinterruptroutine in port_configuration_information (storport), and only message-basedInterrupts. Both methods have been tried. So far they are not clear about their differences.

functionality and ease of writing drivers for Windows. Although WDM is mainly designed to be binary and source compatible between Windows 98 and Windows $, this may not alwa Ys be desired and so specific drivers can is developed for either operating system. WDM drivers can classified into the following types and sub-types:Device function Drivers[edit] A function driver is the main driver for a device. A function driver is typically written by the device vendor and are required (unless the devi

The functions of tables (dm9000.dll) exports are only DriverEntry. It can also be seen from the name that this is the DLL file entry. Next, let's take a closer look at this entry function (in the driver. (implemented in CPP): In this function, there is an ndisminitializewrapper (). This function is used to call notifies NDIS that a new miniport is initializing. This function is provided in NDIS. dll and can be called directly. Next, initialize the str

Miniport Driver (kmdod) sampleCompared to mirror, this drive is closer to my project, as well as the content of the evaluation. As for the contents of this sample, we'll take the time to write it, and here we'll write something about the content of the VidPN. The VidPN Manager works with display DRIVER and miniport DRIVER to jointly manage adapter and devices connected on adapter. Simply put, VidPN is the
