Visual Studio Code project for Linux kernel sources

Ensure the kernel is built (at least, all *.cmd files should be generated):

$ make defconfig
$ make

Clone this repository as ".vscode":

$ git clone [email protected]:amezin/vscode-linux-kernel.git .vscode

Generate compile_commands.json:

$ python .vscode/generate_compdb.py

If you are not compiling kernel for x64, change intelliSenseMode in c_cpp_properties.json. Possible values as of vscode-cpptools 1.0.1:

  • gcc-x86
  • gcc-x64
  • gcc-arm
  • gcc-arm64

Open the project:

$ code .

Out-of-tree builds

#4

Kernel can be built with separate output directory:

$ make O=../linux-build defconfig
$ make O=../linux-build

In this case, you should pass the directory to generate_compdb.py:

$ python .vscode/generate_compdb.py -O ../linux-build

compile_commands.json will still be generated in the current directory (root of the linux repository). Unfortunately, tasks.json will not work out of the box in this configuration (TODO).

Out-of-tree module development

If you build your module with this command:

$ make -C $KDIR M=$PWD modules

You could generate compile_commands.json with:

$ python .vscode/generate_compdb.py -O $KDIR $PWD
