Chris Wilson dcff85c844 drm/i915: Enable i915_gem_wait_for_idle() without holding struct_mutex ... The principal motivation for this was to try and eliminate the struct_mutex from i915_gem_suspend - but we still need to hold the mutex current for the i915_gem_context_lost(). (The issue there is that there may be an indirect lockdep cycle between cpu_hotplug (i.e. suspend) and struct_mutex via the stop_machine().) For the moment, enabling last request tracking for the engine, allows us to do busyness checking and waiting without requiring the struct_mutex - which is useful in its own right. As a side-effect of having a robust means for tracking engine busyness, we can replace our other busyness heuristic, that of comparing against the last submitted seqno. For paranoid reasons, we have a semi-ordered check of that seqno inside the hangchecker, which we can now improve to an ordered check of the engine's busyness (removing a locked xchg in the process). v2: Pass along "bool interruptible" as being unlocked we cannot rely on i915->mm.interruptible being stable or even under our control. v3: Replace check Ironlake i915_gpu_busy() with the common precalculated value Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1470388464-28458-6-git-send-email-chris@chris-wilson.co.uk		2016-08-05 10:54:37 +01:00
