      drm/i915: Remove bogus locking check in the hangcheck code · b838cbee
      Daniel Vetter authored
      You can _never_ assert that a lock is not held, except in some very
      restricted corner cases where it's guranteed that your code is running
      single-threade (e.g. driver load before you've published any pointers
      leading to that lock).
      
      In addition the early return breaks a bunch of testcases since with
      highly concurrent hangcheck stress tests the reset fails to work and
      the test doesn't recover and time out.
      
      This regression has been introduced in

      Aside: It is possible to check whether a given task doesn't hold a
      lock, but only when lockdep is enabled, using the lockdep_assert_held
      stuff.

      drm/modes: Print the mode status in human readable form · e4bf44b3
      Ville Syrjälä authored
      Currently when a mode is rejected the reason is printed as a raw number.
      Having to manually decode that to a enum drm_mode_status value is
      tiresome. Have the code do the decoding instead and print the result
      in a human readable format.
      
      Just having an array of strings indexed with the mode status doesn't
      work since the enum includes negative values. So we offset the status
      by +3 which makes all the indexes non-negative. Also add a bit of
      paranoia into the code to catch out of bounds accesses in case
      someone adds more enum values but forgets to update the code.

      DRM_GEM_CMA_HELPER is depend on HAVE_DMA_ATTRS, or it will break the
      building. The related error (with allmodconfig under xtensa):

      Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next · 44df9c41
      Dave Airlie authored
      Rebase of main pull for 3.20.  There was a mid-air collision between
      the bridge changes and msm eDP support.  And atomic dpms support broke
      msm somewhat, due to using prepare/commit hooks in a different way.
      Compared to the initial pull req, this fixes up a memory leak caused
      by the bridge changes, rebases the eDP support on the bridge changes,
      and migrates to the atomic dpms hooks to fix the dpms breakage.
      
      Highlights (from original pull req):
      
      1) YUV support for mdp4 and mdp5
      2) eDP support
      3) hw cursor support for mdp5[*]
      4) additional hdmi support for apq8084 (snapdragon 805)
      5) few bug fixes
      
      Note that I may have a later pull to enable hdmi hpd irqs.. but
      (un)fortunately I seem to have a particularly troublesome monitor..  I
      managed to figure out a workaround for spurious hpd disconnect irqs
      that works with some of my boards but not others, so holding off on
      that patch for now.  There are also patches for HDCP support, but
      those are waiting on some scm patches outside of drm so I think
      waiting until 3.21 at this point.
