vscode-kernel-module

Basic setup for kernel module development using vscode. When adjusting this template make sure to keep the json generation intact (see below).

Sometimes VSCode localizes the wrong headers. This most often happens when a new file is added that was not built yet. In this case

1. build the module: make (regenerates compile_commands.json)
2. then either restart VSCode or use Developer: Reload Window.

Requirements

You need python.

How this works

In the kernel sources exists a script $KDIR/scripts/gen_compile_commands.py, which gathers compilation artifacts. It creates a json file that maps from source files to the command used to compile those files. VSCode's C/C++ extension can use this information to localize the appropriate header files when parsing a compilation unit. This is configured in c_cpp_properties.json with the key "compileCommands".
