Daniel Vetter e21af88d39 drm/i915: enable ppgtt ... We want to unconditionally enable ppgtt for two reasons: - Windows uses this on snb and later. - We need the basic hw support to work before we can think about real per-process address spaces and other cool features we want. But Chris Wilson was complaining all over irc and intel-gfx that this will blow up if we don't have a module option to disable it. Hence add one, to prevent this. ppgtt support seems to slightly change the timings and make crashy things slightly more or less crashy. Now in my testing and the testing this got on troublesome snb machines, it seems to have improved things only. But on ivb it makes quite a few crashes happen much more often, see https://bugs.freedesktop.org/show_bug.cgi?id=41353 Luckily Eugeni Dodonov seems to have a set of workarounds that fix this issue. v2: Don't try to enable ppgtt on pre-snb. v3: Pimp commit message and make Chris Wilson less grumpy by adding a module option. v4: New try at making Chris Wilson happy.
