¶ Introduction to windows desktop driver development
Basic Knowledge Preparation: Familiar with C/C++ programming language and understand the concepts of function pointers, callback functions and event handlers. basic use of Visual Studio.
¶ Drivers are categorized into the following types
- device function drivers
- device filter drivers
- software drivers
- file system filter drivers
- file system drivers
¶ Software Driver Development Classification
Categorized into the WDM model and the WDF model, WDM drivers are trusted kernel-mode components, so the system provides limited checks on driver input. In contrast, the WDF model focuses on the requirements of the driver, and the framework library handles most of the interaction with the system. Microsoft recommends using the WDF model for new driver development.
The WDF model is divided into two types of driver development: KMDF kernel mode drivers and UMDF user mode drivers. We often say that the development is the KMDF kernel mode driver.
¶ Development environment:
VS2022 + SDK (according to the target board system version to download) + driver toolkit WDK
VS2022 installation: select "desktop development using c++" and "Visual Studio extension development" two contents.
The SDK can be installed on the network, and the WDK can be installed on the network.
For installation, please refer to the Microsoft tutorial: https://learn.microsoft.com/zh-cn/windows-hardware/drivers/download-the-wdk#download-and-install-the-windows-11-version- 22h2-wdk
¶ Introduction to the process of creating a KMDF driver:
Start Visual Studio.
In the startup dialog box, select "Create New Project", or select "Project" in the "New | Visual Studio File" menu. Select "Create New Project" in the startup dialog box or select "Project" from the "New | Visual Studio" File menu.
In the right pane of the Create New Project dialog box, locate and select Kernel Mode Driver (KMDF). Select Next.
Fill in the Project Name, Location and Solution Name boxes and select Create. For more information, see Writing KMDF Drivers Based on Templates.
At this point, your driver project implements the general code required by most KMDF drivers. You can now provide code specific to your device.
¶ Driver installation and debugging
During the debugging phase, the target machine needs to be configured in test mode, otherwise the driver cannot be installed.
Run the following terminal command with administrator privileges: bcdedit /set testsigning on to reboot the system.
If you don't want to test anymore, exit the test mode: bcdedit /set testsigning off and reboot the system.
Compile the driver folder, copy it to the target machine, there is a file "XXX.inf" in the driver folder on the target machine, right click the mouse to install it.
Because the driver debugging and common application debugging methods are different, generally by viewing the driver process log to determine and analyze whether the driver is running normally.
Need to use Microsoft's tools.
DebugView (view ktprint print log) Download: https://learn.microsoft.com/zh-cn/sysinternals/downloads/debugview
Driver Monito (view the log of the WPP framework) download address: https://www.drivers.com/download-monitor-drivers/
¶ Driver Signature
When the driver debugging good, no problem, need to give the driver signature, the driver can be installed in the official mode of the system.
Driver signing: you can let Microsoft sign the driver, or let a third-party organization to help sign the driver. The price is different.
¶ New device added to the system:
To mount an external device via I2C/SPI bus, you need to declare the device in the ASL CODE of the motherboard, so that the new device will appear in the device manager of the system.
How to add a new device will be mentioned later in the I2C/SPI/NFC development.
The target system in test mode, driver development process, do not brush the BIOS, the new device can be injected into the registry, you can carry out development and testing.
The process of injecting a new device into the registry (this process is only effective when the system is in test mode).
Tools used: 1.
1.SDK comes with asl.exe: path C:\Program Files (x86)\Windows Kits\10\Tools\SDK specific version number\x64\ACPIVerify\
2.iasl-win: download address:https://www.intel.com/content/www/us/en/download/774881/acpi-component-architecture-downloads-windows-binary-tools .html
In the target machine as administrator, run the following commands.
1) Read the BIOS configuration from the registry cache and save it to the DSDT0000.bin file.
.\asl.exe /tab=DSDT /c
2) Decompile DSDT0000.bin file, generate DSDT0000.dsl (ASL CODE file).
.\iasl.exe -ve . \DSDT0000.bin
3) Modify the DSDT0000.dsl file, add new devices to change the file
According to the actual need to add devices to the file, followed by the use of I2C/SPI/NFC in the introduction of specific examples need to add the content.
4) Compile the modified DSDT0000.dsl, which will generate DSDT0000.aml file
.\iasl.exe -ve . \DSDT0000.dsl
5) Write to registry cache
.\asl.exe /loadtable DSDT0000.aml
6)Ignore signature
Bcdedit /set testsigning on
7)Reboot the system so that you can see the new device in the device manager.
To disable the ASL code, uninstall it.
key. \asl.exe /loadtable DSDT0000.aml -d
Reboot the system, and you will be back to the unadded device state.
When the new device is ready for debugging, you need to update the BISO code and re-flash the BIOS.
