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 a5f2fafece141ef3509e686cea576366d55cabb6 Merge: 71f4e45a4ed3 860433ed2a55 Author: Dave Airlie Date: Wed Feb 20 12:16:30 2019 +1000 Merge https://gitlab.freedesktop.org/drm/msm into drm-next
