From 2cc86b826070cf312d7b0571e383c56d31a1fe5c Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 26 Aug 2013 19:51:00 -0300 Subject: [PATCH] drm/i915: Always prefer CPU relocations with LLC MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit A follow-on to the update of the LLC coherency logic is that we can rely on the LLC being coherent with the CS for rewriting batchbuffers irrespective of their cache domain. (This should have no effect currently as all the batch buffers are expected to be I915_CACHE_LLC and so using the cpu relocation path anyway.)
