Windows ODP Drivers

This repository contains Windows drivers that demonstrate and enable Open Device Platform (ODP) scenarios.

Code Organization

Code is organized by platform under the drivers directory. Place platform-specific drivers in their platform folder, and place shared drivers in a common folder when applicable.

GitHub Workflows

.github/workflows/build-drivers.yml - Builds all drivers and publishes build artifacts.

Compiling Code Locally

Build drivers locally with MSBuild from an Enterprise WDK (EWDK) command prompt.

1. Get the EWDK

1. Open the Microsoft WDK download page and download the Enterprise WDK ISO that matches your target SDK/WDK release.

2. Mount the ISO in Windows Explorer.

3. Open the mounted drive and run LaunchBuildEnv.cmd.

4. In the build environment prompt, go to your repo root:

   cd /d D:\git\odp-windows-drivers

Notes:

• Build from the EWDK prompt so INCLUDE, LIB, PATH, and toolchain variables are already configured.
• If your EWDK shell opens in x86 mode, switch to the x64 build environment before compiling drivers.

2. Restore NuGet packages

Run restore for each project before building:

nuget restore drivers\qemu\pl061gpio\pl061gpio.vcxproj -ConfigFile %APPDATA%\NuGet\NuGet.Config

3. Build each driver project

Build using the same configuration used by CI (Release + ARM64):

msbuild drivers\qemu\pl061gpio\pl061gpio.vcxproj /p:Configuration=Release /p:Platform=ARM64 /p:WarningLevel=4

4. Optional: Build all driver vcxproj files recursively

If new drivers are added, you can build all project files under drivers in one loop from the EWDK prompt:

   for /r drivers %F in (*.vcxproj) do (
     nuget restore "%F" -ConfigFile %APPDATA%\NuGet\NuGet.Config
     msbuild "%F" /p:Configuration=Release /p:Platform=ARM64 /p:WarningLevel=4
   )

5. Build output

Driver binaries (.sys) are generated in each project output folder under drivers.
