From 1c0582866fb459c829538e4a7a7fcf177fc56aa7 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 10 Nov 2017 12:29:40 -0800 Subject: headers: Import drm-next uapi headers. These will be used for tests that want to use a local copy of the headers instead of depending on libdrm releases. Taken from drm-next d65d31388a23 ("Merge tag 'drm-misc-next-fixes-2017-11-07' of git://anongit.freedesktop.org/drm/drm-misc into drm-next") See README for rules on updating these headers.
