I believe that coverage in the kernel can be measured by enabling kernel profiling, and then using the kernbb(8) tool to dump the profile buffers into a form that can be used by gcov(1). The man pages for kernbb(8) and kgmon(8) should have the necessary details. They require a kernel configured for profiling, and details should be in there and config(8).
