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 ca797d29cd63e7b71b4eea29aff3b1cefd1ecb59 Merge: 2c1c55cb75a9 010d118c2061 Author: Dave Airlie <airlied@redhat.com> Date: Mon Dec 4 09:40:35 2017 +1000 Merge tag 'drm-intel-next-2017-11-17-1' of git://anongit.freedesktop.org/drm/drm-intel into drm-next
