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 7846b12fe0b5feab5446d892f41b5140c1419109 Merge: 7ebdb0d d78acfe Author: Dave Airlie Date: Tue Aug 29 10:38:14 2017 +1000 Merge branch 'drm-vmwgfx-next' of git://people.freedesktop.org/~syeh/repos_linux into drm-next
