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 8f3d9f354286745c751374f5f1fcafee6b3f3136 Author: Linus Torvalds Date: Sun Apr 12 12:35:55 2020 -0700 Linux 5.7-rc1
