Chris Wilson 3da3c5c1c9 drm/i915: Exclude low pages (128KiB) of stolen from use ... The GPU is trashing the low pages of its reserved memory upon reset. If we are using this memory for ringbuffers, then we will dutiful resubmit the trashed rings after the reset causing further resets, and worse. We must exclude this range from our own use. The value of 128KiB was found by empirical measurement (and verified now with a selftest) on gen9.
