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 d9aa1da9a8cfb0387eb5703c15bd1f54421460ac Merge: 7c9aa0f7463e 28e671114fb0 Author: Dave Airlie Date: Mon Aug 7 13:49:24 2023 +1000 Merge tag 'drm-intel-gt-next-2023-08-04' of git://anongit.freedesktop.org/drm/drm-intel into drm-next
