      Manually resolve the conflict between the new enum drm property
      helpers in drm-next and the new "force-dvi" option that the "audio" output
      property gained in drm-intel-next.
      
      While resolving this conflict, switch the new drm_prop_enum_list to
      use the newly introduced enum defines instead of magic values.

      drm/i915/lvds: Always use the presence pin for LVDS on PCH · f3cfcba6
      Chris Wilson authored
      With the introduction of the PCH, we gained an LVDS presence pin but we
      continued to use the existing logic that asserted that LVDS was only
      supported on certain mobile chipsets. However, there are desktop
      IronLake systems with LVDS attached which we fail to detect. So for PCH,
      trust the LVDS presence pin and quirk all the lying manufacturers.

      drm/i915: Record the in-flight requests at the time of a hang · 52d39a21
      Chris Wilson authored
      Being able to tally the list of outstanding requests with the sequence
      of commands in the ringbuffer is often useful evidence with respect to
      driver corruption.
      
      Note that since this is the umpteenth per-ring data structure to be added
      to the error state, I've coallesced the nearby loops (the ringbuffer and
      batchbuffer) into a single structure along with the list of requests.  A
      later task would be to refactor the ring register state into the same
      structure.
      
      v2: Fix pretty printing of requests so that they are parsed correctly by
      intel_error_decode and use the 0x%08x format for seqno for consistency

      drm/i915: Record the tail at each request and use it to estimate the head · a71d8d94
      Chris Wilson authored
      By recording the location of every request in the ringbuffer, we know
      that in order to retire the request the GPU must have finished reading
      it and so the GPU head is now beyond the tail of the request. We can
      therefore provide a conservative estimate of where the GPU is reading
      from in order to avoid having to read back the ring buffer registers
      when polling for space upon starting a new write into the ringbuffer.
      
      A secondary effect is that this allows us to convert
      intel_ring_buffer_wait() to use i915_wait_request() and so consolidate
      upon the single function to handle the complicated task of waiting upon
      the GPU. A necessary precaution is that we need to make that wait
      uninterruptible to match the existing conditions as all the callers of
      intel_ring_begin() have not been audited to handle ERESTARTSYS
      correctly.
      
      By using a conservative estimate for the head, and always processing all
      outstanding requests first, we prevent a race condition between using
      the estimate and direct reads of I915_RING_HEAD which could result in
      the value of the head going backwards, and the tail overflowing once
      again. We are also careful to mark any request that we skip over in
      order to free space in ring as consumed which provides a
      self-consistency check.
      
      Given sufficient abuse, such as a set of unthrottled GPU bound
      cairo-traces, avoiding the use of I915_RING_HEAD gives a 10-20% boost on
      Sandy Bridge (i5-2520m):
        firefox-paintball  18927ms -> 15646ms: 1.21x speedup
        firefox-fishtank   12563ms -> 11278ms: 1.11x speedup
      which is a mild consolation for the performance those traces achieved from
      exploiting the buggy autoreported head.
      
      v2: Add a few more comments and make request->tail a conservative
      estimate as suggested by Daniel Vetter.

      drm/i915: Fix race condition in accessing GMBUS · 8a8ed1f5
      Yufeng Shen authored
      GMBUS has several ports and each has it's own corresponding
      I2C adpater. When multiple I2C adapters call gmbus_xfer() at
      the same time there is a race condition in using the underlying
      GMBUS controller. Fixing this by adding a mutex lock when calling
      gmbus_xfer().
      
      v2: Moved gmbus_mutex below intel_gmbus and added comments.
      Rebased to drm-intel-next-queued.

      drm/i915: add a "force-dvi" HDMI audio mode · b1d7e4b4
      Wu Fengguang authored
      When HDMI-DVI converter is used, it's not only necessary to turn off
      audio, but also to disable HDMI_MODE_SELECT and video infoframe. Since
      the DVI mode is mainly tied to audio functionality from end user POV,
      add a new "force-dvi" audio mode:
      
      	xrandr --output HDMI1 --set audio force-dvi
      
      Note that most users won't need to set this and happily rely on the EDID
      based DVI auto detection.

      This patch replaces the locking from the downclock routines with an assert
      to ensure the registers are indeed unlocked. Without this patch, pre-SNB
      devices would lock the registers when downclocking which would cause a
      WARNING on suspend/resume with downclocking enabled.
      
      Note: To hit this bug, you need to have lvds downclocking enabled.
