Matthew Auld 2f720aac93 drm/i915: don't do allocate_va_range again on PIN_UPDATE ... If a vma is already bound to a ppgtt, we incorrectly call allocate_va_range again when doing a PIN_UPDATE, which will result in over accounting within our paging structures, such that when we do unbind something we don't actually destroy the structures and end up inadvertently recycling them. In reality this probably isn't too bad, but once we start touching PDEs and PDPEs for 64K/2M/1G pages this apparent recycling will manifest into lots of really, really subtle bugs. v2: Fix the testing of vma->flags for aliasing_ppgtt_bind_vma Fixes: ff685975d9 ("drm/i915: Move allocate_va_range to GTT") Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/20170512091423.26085-1-chris@chris-wilson.co.uk (cherry picked from commit 1f23475c89) Signed-off-by: Jani Nikula <jani.nikula@intel.com>		2017-05-15 14:44:33 +03:00
