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 3393649977f9a8847c659e282ea290d4b703295c Merge: cbc2e82932ae ced026e959be Author: Dave Airlie Date: Fri Aug 28 13:51:30 2020 +1000 Merge tag 'drm-intel-next-2020-08-24-1' of git://anongit.freedesktop.org/drm/drm-intel into drm-next
