It's common for drivers that share same physical components to also duplicate source code (or at least portions of it). A good example is both drivers/gpu/drm/amdgpu/* and drivers/gpu/drm/radeon/* have a header file called atombios.h. While their contents aren't the same, a lot of their structs have the exact same names which makes navigating through the code base a bit messy as cscope will show up 'references' across drivers which aren't exactly correct. Add IGNORE_DIRS variable, which specifies which directories to be ignored from indexing. Example: make ARCH=x86 IGNORE_DIRS="drivers/gpu/drm/radeon tools" cscope
