      drm/i915: fix reference counting in i915_gem_create · d861e338
      Daniel Vetter authored
      This function is called without the dev->struct_mutex held, hence we
      need to use the _unlocked unreference variants.
      
      As soon as the object is registered userspace can sneak in here with a
      gem_close ioctl call, so the object can (and with my new evil tests
      actually does) get the final unreference in this place. The lack of
      locking then results in hilarity and some good leakage.
      
      To fix this we simply need to revert
      
      Chris Wilson <chris@chris-wilson.co.uk>
      
      v2: We need to make the trace call _before_ we drop our ref - the
      object might very well be gone by then already.
      
      v3: Just revert the original patch as suggested by Chris Wilson.

      drm/i915: Use Graphics Base of Stolen Memory on all gen3+ · 17fec8a0
      Chris Wilson authored
      So I made the mistake of missing that the desktop and mobile chipsets
      have different layouts in their PCI configurations, and we were
      incorrectly setting the wrong physical address for stolen memory on
      mobile chipsets.
      
      Since all gen3+ are actually consistent in the location of the GBSM
      register in the PCI configuration space on device 2 (the GPU), use it.

      drm/i915: disable stolen mem for OVERLAY_NEEDS_PHYSICAL · f63a484c
      Daniel Vetter authored
      Our phys_object code can't deal with stolen memory and so blows up.
      Fixing this is quite a bit of work and not worth it much for a single
      page object, so just opt-out.
      
      This is necessary prep work to enable stolen on gen2/3 platforms where
      the overlay register file isn't stored in the gtt.
