From a00d825de9284922a4977eaa7d513f88044ccc4a Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 19 Feb 2014 22:05:48 -0800 Subject: [PATCH] drm/i915: Split GEN6 PPGTT cleanup This cleanup is similar to the GEN8 cleanup (though less necessary). Having everything split will make cleaning the initialization path error paths easier to understand.
