i915_gem_object_save_bit_17_swizzle — save bit 17 swizzling
void i915_gem_object_save_bit_17_swizzle ( | struct drm_i915_gem_object * obj); |
This function saves the bit 17 of each page frame number so that swizzling
can be fixed up later on with i915_gem_object_do_bit_17_swizzle. This must
be called before the backing storage can be unpinned.
