From 2fe486c7eae9fc5b52297aed0e4008df6b66b01c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 13 Nov 2014 22:12:53 +0200 Subject: [PATCH] drm/i915: Drop WaRsForcewakeWaitTC0:vlv MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit GEN6_GT_THREAD_STATUS_REG doesn't seem to exist on VLV. Reads just give 0x0 no matter what the state of the render and media wells. There was also some hint in the Gunit HAS that thread status not being needed on VLV, and hence dropped when bringing stuff over from the IVB design. Not really a definite comment about the specific register itself though. Also the w/a itself is no longer listed for VLV in the database. It was there some time ago in the past, but I guess someone figured out the mistake and dropped it. So let's just drop it from the code as well.
