From 3cf1934abe88103fcbeff88bbaee8a094502e6cb Mon Sep 17 00:00:00 2001 From: Oscar Mateo Date: Wed, 4 Oct 2017 08:39:52 -0700 Subject: [PATCH] drm/i915/cnl: Do not add an extra page for precaution in the Gen10 LRC size BSpec indicates exactly 16752 DWORDs (17 pages), plus one page for PPHWSP. Please notice that, when looking at the BSpec context image table, the right filter has to be applied (e.g. "CNL") as some rows are excluded for specific GENs.
