This directory contains a copy of the installed kernel headers required by several drivers to communicate with the kernel. Whenever one 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 1aa63ddf726ea049279989b93b69b57ce6efd75b Merge: 774f1eeb18b0 14d0066b8477 Author: Dave Airlie Date: Wed Apr 22 10:40:34 2020 +1000 Merge tag 'drm-misc-next-2020-04-14' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
