This directory contains a copy of the installed kernel headers required by the anv & i965 drivers to communicate with the kernel. Whenever either of those driver needs new definitions for new kernel APIs, these files should be updated. These files in master should only be updated once the changes have landed in the drm-next tree. You can copy files installed after running this from the kernel repository, at version the drivers require : $ make headers_install INSTALL_HDR_PATH=/path/to/install The last update was done at the following kernel commit : commit 78230c46ec0a91dd4256c9e54934b3c7095a7ee3 Merge: b65bd4031156 037f03155b7d Author: Dave Airlie Date: Wed Mar 21 14:07:03 2018 +1000 Merge tag 'omapdrm-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux into drm-next
