This allows you to look at the current DPM state via debugfs. Due to the way the hardware works on these asics, there's no way to look up exactly what power state we are in, so we make the best guess we can based on the current sclk. v2: Anthoine's version v3: fix ref div Signed-off-by:Alex Deucher <alexander.deucher@amd.com>

One feature latecomer, I've forgotten to merge the patch to reeanble the Haswell power well feature now that the audio interaction is fixed up. Since that was the only unfixed issue with it I've figured I could throw it in a bit late, and it's trivial to revert in case I'm wrong. Otherwise all bug/regression fixes: - Fix status page reinit after gpu hangs, spotted by more paranoid igt checks. - Fix object list walking fumble regression in the shrinker (only the counting part, the actual shrinking code was correct so no Oops potential), from Xiong Zhang. - Fix DP 1.2 bw limits (Imre). - Restore legacy forcewake on ivb, too many broken biosen out there. We dump a warn though that recent userspace might fall over with that config (Guenter Roeck). - Patch up the gen2 cs tlb w/a. - Improve the fence coherency w/a now that we have a better understanding what's going on. The removed wbinvd+ipi should make -rt folks happy. Big thanks to Jon Bloomfield for figuring this out, patches from Chris. - Fix write-read race when switching ring (Chris). Spotted with code inspection, but now we also have an igt for it. There's an ugly regression we're still working on introduced between 3.10-rc7 and 3.10.0. Unfortunately we can't just revert the offender since that one fixes another regression :( I've asked Steven to include my -fixes branch into linux-next to prevent such fallout in the future, hopefully. * tag 'drm-intel-fixes-2013-07-11' of git://people.freedesktop.org/~danvet/drm-intel: Revert "drm/i915: Workaround incoherence between fences and LLC across multiple CPUs" drm/i915: Fix incoherence with fence updates on Sandybridge+ drm/i915: Fix write-read race with multiple rings Partially revert "drm/i915: unconditionally use mt forcewake on hsw/ivb" drm/i915: fix lane bandwidth capping for DP 1.2 sinks drm/i915: fix up ring cleanup for the i830/i845 CS tlb w/a drm/i915: Correct obj->mm_list link to dev_priv->dev_priv->mm.inactive_list drm/i915: switch disable_power_well default value to 1 drm/i915: reinit status page registers after gpu reset

But the SLUB code is relatively lockless, and the spin_locks there are raw_spin_locks (not converted to mutexes), thus I believe this bug can happen in mainline without -rt features. The -rt patch is just good at triggering mainline bugs ;-) Anyway, looking at where this crashed, it seems that the page variable can be NULL when passed to the node_match() function (which does not check if it is NULL). When this happens we get the above panic. As page is only used in slab_alloc() to check if the node matches, if it's NULL I'm assuming that we can say it doesn't and call the __slab_alloc() code. Is this a correct assumption? Acked-by:
