      drm/msm/mdp5: fix for crash in disable path · e5989ee1
      Rob Clark authored
      Seems like disable can race with complete_flip() in process of disabling
      a crtc, leading to:

      It makes no sense to free the ctl without disabling all stages, so lets
      just move them together to avoid the crash.

      drm/msm: adreno a306 support · de558cd2
      Rob Clark authored
      As found in apq8016 (used in DragonBoard 410c) and msm8916.
      
      Note that numerically a306 is actually 307 (since a305c already claimed
      306).  Nice and confusing.

      drm/msm: clarify downstream bus scaling · 6490ad47
      Rob Clark authored
      A few spots in the driver have support for downstream android
      CONFIG_MSM_BUS_SCALING.  This is mainly to simplify backporting the
      driver for various devices which do not have sufficient upstream
      kernel support.  But the intentionally dead code seems to cause
      some confusion.  Rename the #define to make this more clear.

      drm/msm/adreno: dump scratch regs and other info on hang · 26716185
      Rob Clark authored
      Dump a bit more info when the GPU hangs, without having hang_debug
      enabled (which dumps a *lot* of registers).  Also dump the scratch
      registers, as they are useful for determining where in the cmdstream
      the GPU hung (and they seem always safe to read when GPU has hung).
      
      Note that the freedreno gallium driver emits increasing counter values
      to SCRATCH6 (to identify tile #) and SCRATCH7 (to identify draw #), so
      these two in particular can be used to "triangulate" where in the
      cmdstream the GPU hung.

      drm/virtio: remove some dead code · 3f05eb4e
      Dan Carpenter authored
      The goto is correct, and we never reach the return statement so just
      delete the dead code.
