      drm/i915: Enable pixel replicated modes on BDW and HSW. · ebb69c95
      Clint Taylor authored
      Haswell and later silicon has added a new pixel replication register
      to the pipe timings for each transcoder. Now in addition to the
      DPLL_A_MD register for the pixel clock double, we also need to write
      to the TRANS_MULT_n (0x6002c) register to double the pixel data. Writing
      to the DPLL only double the pixel clock.
      
      ver2: Macro name change from MULTIPLY to PIPE_MULTI. (Daniel)
      ver3: Do not set pixel multiplier if transcoder is eDP (Ville)
      ver4: Macro name change to PIPE_MULT and default else pixel_multiplier

      drm/i915: Do not leak pages when freeing userptr objects · c479f438
      Tvrtko Ursulin authored
      sg_alloc_table_from_pages() can build us a table with coalesced ranges which
      means we need to iterate over pages and not sg table entries when releasing
      page references.

      drm/i915: Do not store the error pointer for a failed userptr registration · e9681366
      Chris Wilson authored
      If we fail to create our mmu notification, we report the error back and
      currently store the error inside the i915_mm_struct. This not only causes
      subsequent registerations of the same mm to fail (an issue if the first
      was interrupted by a signal and needed to be restarted) but also causes
      us to eventually try and free the error pointer.

      This reverts commit c76bb61a.
      
      It's apparently too broken so that Rodrigo submitted a patch to add a
      config option for it. Given that the design is also ... suboptimal and
      that I've only merged this to get lead engineers and managers off my
      back for one second let's just revert this.
      
      /me puts on combat gear again
