      drm/i915: Invalidate the relocation presumed_offsets along the slow path · 262b6d36
      Chris Wilson authored
      In the slow path, we are forced to copy the relocations prior to
      acquiring the struct mutex in order to handle pagefaults. We forgo
      copying the new offsets back into the relocation entries in order to
      prevent a recursive locking bug should we trigger a pagefault whilst
      holding the mutex for the reservations of the execbuffer. Therefore, we
      need to reset the presumed_offsets just in case the objects are rebound
      back into their old locations after relocating for this exexbuffer - if
      that were to happen we would assume the relocations were valid and leave
      the actual pointers to the kernels dangling, instant hang.

      drm/i915/eDP: do not write power sequence registers for ghost eDP · f30d26e4
      Jani Nikula authored
      Some machines detect an eDP port even if it's not really there, and eDP
      initialization has a fail path for this. Typically such machines have an
      LVDS display instead. A regression introduced in

          drm/i915: make edp panel power sequence setup more robust
      
      updated the power sequence registers PCH_PP_ON_DELAYS, PCH_PP_OFF_DELAYS,
      and PCH_PP_DIVISOR also in the ghost eDP case, messing up the LVDS display.
      
      Split the power sequencer initialization into two, delaying the register
      updates until after we know the eDP is real.
      
      Note: Keep the PP_CONTROL unlocking in the first part, even if it does not
      update registers, per the commit message of the above mentioned commit.
