I've cloned your
https://anongit.freedesktop.org/git/drm-tip.git
and am now trying to build it (just the master; I haven't tried previous commits). The build fails at the modules stage with
Makefile:1015: recipe for target 'drivers' failed make: *** [drivers] Error 2
What is the earliest commit I can try to build so it will still include the config options you mention?
I'm sure I'm just missing something obvious..
