      drm/i915: preserve pipe A quirk in i9xx_set_pipeconf · 67c72a12

          drm/i915: set up PIPECONF explicitly for i9xx/vlv platforms
      
      Ville brough up the idea that this is just the pipe A quirk gone
      wrong.
      
      Note that after resume the bios might or might not have enabled pipe A
      already.  We have a bit of magic to make sure that on resume we set up
      a decent mode for pipe A, but I fear if I just smash pipe A to always
      on we'd enable it in a bogus state and hang the hw. Hence the
      readback.
      
      v2: Clarify the logic a bit as suggested by Chris. Also amend the
      commit message to clarify why we don't unconditionally enable the
      pipe.

      drm/i915/tv: clear adjusted_mode.flags · 1062b815
      Daniel Vetter authored
      The native TV encoder has it's own flags to adjust sync modes and
      enabled interlaced modes which are totally irrelevant for the adjusted
      mode. This worked out nicely since the input modes used by both the
      load detect code and reported in the ->get_modes callbacks all have no
      flags set, and we also don't fill out any of them in the ->get_config
      callback.
      
      This changed with the additional sanitation done with
      
      commit 2960bc9c

          drm/i915: make user mode sync polarity setting explicit
      
      sinc now the "no flags at all" state wouldn't fit through core code
      any more. So fix this up again by explicitly clearing the flags in the
      ->compute_config callback.
      
      Aside: We have zero checking in place to make sure that the requested
      mode is indeed the right input mode we want for the selected TV mode.
      So we'll happily fall over if userspace tries to pull us.  But that's
      definitely work for a different patch series. So just add a FIXME
      comment for now.

      drm/i915/dp: increase i2c-over-aux retry interval on AUX DEFER · 8d16f258
      Jani Nikula authored
      There is no clear cut rules or specs for the retry interval, as there
      are many factors that affect overall response time. Increase the
      interval, and even more so on branch devices which may have limited i2c
      bit rates.

      drm/i915: Use a temporary va_list for two-pass string handling · e29bb4eb

      Author: Mika Kuoppala <mika.kuoppala@linux.intel.com>
      Date:   Thu May 23 13:55:35 2013 +0300
      
          drm/i915: avoid big kmallocs on reading error state
      
      we introduce a two-pass mechanism for splitting long strings being
      formatted into the error-state. The first pass finds the length, and the
      second pass emits the right portion of the string into the accumulation
      buffer. Unfortunately we use the same va_list for both passes, resulting
      in the second pass reading garbage off the end of the argument list. As
      the two passes are only used for boundaries between read() calls, the
      corruption is only rarely seen.
      
      This fixes the root cause behind

      'samples' is 64bit operant, but do_div() second parameter is 32.
      do_div silently truncates high 32 bits and calculated result
      is invalid.
      
      In case if low 32bit of 'samples' are zeros then do_div() produces
      kernel crash.
