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 247f34f7b80357943234f93f247a1ae6b6c3a740 Author: Linus Torvalds Date: Sun Oct 23 15:27:33 2022 -0700 Linux 6.1-rc2
