From ec5cc0f9b019af95e4571a9fa162d94294c8d90b Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 12 Jun 2014 10:28:55 +0100 Subject: [PATCH] drm/i915: Restrict GPU boost to the RCS engine Make the assumption that media workloads are not as latency sensitive for __wait_seqno, and that upclocking the GPU does not affect the BLT engine. Under that assumption, we only wait to forcibly upclock the GPU when we are stalling for results from the render pipeline.
