From f3f4c4d68a2862c361fd9890998275da5ef02724 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 7 Dec 2016 15:49:39 +0100 Subject: [PATCH] drm: Allow CAP_PRIME on !MODESET MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit vgem (and our igt tests using vgem) need this. I suspect etnaviv will fare similarly. v2. Make it build. Oops.
