Check if your code follows kernel code style#

The Linux kernel has a very clear and well-defined code style automated by a tool named You can use this script to check a file or a patch, and it has a large number of options. Although this tool has powerful features, it requires multiple parameters for different contexts, which can make it tedious to use.

kw tries to deliver a unified development experience in the same way that it provides a simple interface for developers to access some supported tools by the kernel. For this reason, kw provides the kw codestyle <target> feature, which will identify if the target is a folder, file, or patch with the same command line. For example, you can point to a folder:

kw codestyle drivers/gpu/drm/amd/display/amdgpu_dm/

or you can point it to a file:

kw codestyle drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c

That is all you need to know about kernel code style checking under kw management.
