If you want to test the ABI file generation, the patchset is at: https://git.linuxtv.org/mchehab/experimental.git/log/?h=abi_patches_v7 You can easily build just the sysfs firmware attribute class ABI with something like this: $ mkdir -p fodir && cp Documentation/ABI/testing/sysfs-class-firmware-attributes fodir/ && ./scripts/get_abi.pl rest -dir fodir/ --rst-source >Documentation/foo/abi.rst && make SPHINXDIRS=foo htmldocs You can also see it at: http://www.infradead.org/~mchehab/kernel_docs/foo/abi.html Thanks, Mauro
