      entering rc6 often enough (and hence blowing through too much power).  It
      seems to be a timing-related issue and can be mitigated by frobbing the
      magic tuning parameters. We're still working on that one. Also, we still
      have some fallout from the hw context support, but you can only hit that
      with mesa master."

      drm/i915: Apply post-sync write for pipe control invalidates · 7d54a904
      Chris Wilson authored
      When invalidating the TLBs it is documentated as requiring a post-sync
      write. Failure to do so seems to result in a GPU hang.
      
      Exposure to this hang on IVB seems to be a result of removing the extra
      stalls required for SNB pipecontrol workarounds:

      drm/i915: reorder edp disabling to fix ivb MacBook Air · 35a38556
      Daniel Vetter authored
      eDP is tons of fun. It turns out that at least the new MacBook Air 5,1
      model absolutely doesn't like the new force vdd dance we've introduced
      in
      
      commit 6cb49835
      Author: Daniel Vetter <daniel.vetter@ffwll.ch>
      Date:   Sun May 20 17:14:50 2012 +0200
      
          drm/i915: enable vdd when switching off the eDP panel
      
      But that patch also tried to fix some neat edp sequence issue with the
      force_vdd timings. Closer inspection reveals that we've raised
      force_vdd only to do the aux channel communication dp_sink_dpms. If we
      move the edp_panel_off below that, we don't need any force_vdd for the
      disable sequence, which makes the Air happy.
      
      Unfortunately the reporter of the original bug that the above commit
      fixed is travelling, so we can't test whether this regresses things.
      But my theory is that since we don't check for any power-off ->
      force_vdd-on delays in edp_panel_vdd_on, this was the actual
      root-cause of this failure. With that force_vdd dance completely
      eliminated, I'm hopeful the original bug stays fixed, too.
      
      For reference the old bug, which hopefully doesn't get broken by this:
      
      https://bugzilla.kernel.org/show_bug.cgi?id=43163
      
      In any case, regression fixers win over plain bugfixes, so this needs
      to go in asap.
      
      v2: The crucial pieces seems to be to clear the force_vdd flag
      uncoditionally, too, in edp_panel_off. Looks like this is left behind
      by the firmware somehow.
      
      v3: The Apple firmware seems to switch off the panel on it's own, hence
      we still need to keep force_vdd on, but properly clear it when switching
      the panel off.

          drm/i915: fix pixel color depth setting on eDP
      
      Since then we've fixed up the dp link bandwidth calculation code and
      should now automatically fall back to 6bpc dithering. So this is
      unnecessary.
      
      Furthermore it seems to break the new MacbookPro with retina display,
      hence let's just rip this out.

      drm/i915: Fix blank panel at reopening lid · 770c1231
      Takashi Iwai authored
      When you reopen the lid on a laptop with PCH, the panel suddenly goes
      blank sometimes.  It seems because BLC_PWM_CPU_CTL register is cleared
      to zero when BLC_PWM_CPU_CTL2 and BLC_PWM_PCH_CTL1 registers are
      enabled.
      
      This patch fixes the problem by moving the call of the function setting
      BLC_PWM_CPU_CTL after enabling other two registers.

      - dmar vs. dma_buf imprt fix (Dave Airlie)
      - 2 patches to fight down forcewake issues on snb. This is the stuff I've
        talked about 2 weeks ago already, it's a minefield. Investigation still
        going on, but afaict this is the best we have for now.
      - a few minor things to keep coverty&compiler happy (Alan, Davendra,
        Stéphane)
      - tons of hsw pci ids - this one is a bit late because internal approval
        sometimes takes a while, but ppl in charge finally agreed that world+dog
        already knows about ult and crw haswell variants ;-)
      
      Wrt regressions I'm aware of:
      - the power regression due to semaphores=1. Ben is running around with a
        killawatt, unfortunately we have a hard time reproducing this one. And
        this /shouldn't/ increase power usage. Ben has turned up a few odds bits
        though already.
      - the lvds fix in 3.6-rc1 broke a backlight after lid close/open (but can
        be resurrected with a modeset cycle). I guess we anger the bios - I'm
        still looking into this one.
      - gmbus broke edid reading on an odd-ball monitor, we need to fall-back.
        Due to vacation (both mine&the reporter's) this is stalling for a final
        patch and a tested-by on it. But issue is fully diagnosed."

      Daniel Vetter authored
      We may only start to set up the new register values after having
      confirmed that the ring is truely off. Otherwise the hw might lose the
      newly written register values. This is caught later on in the init
      sequence, when we check whether the register writes have stuck.
