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 54ecb8f7028c5eb3d740bb82b0f1d90f2df63c5c Author: Linus Torvalds Date: Mon Sep 30 10:35:40 2019 -0700 Linux 5.4-rc1
