From 666fbcf5c21d8d8654b00b9c2e21a3caf070e9f8 Mon Sep 17 00:00:00 2001 From: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Wed, 13 Apr 2016 17:26:42 +0300 Subject: [PATCH] drm/i915: Don't program eLLC IDI hash mask for gen9+ For gen9 onwards, eDRAM is a true memory side cache. So there is no need to program idi hash mask as it is for eLLC only. v2: INTEL_GEN (Chris), s/has/hash (Matthew) Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> --- drivers/gpu/drm/i915/i915_gem.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index b37ffea8b458..3e1222b57fee 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -4892,7 +4892,7 @@ i915_gem_init_hw(struct drm_device *dev) /* Double layer security blanket, see i915_gem_init() */ intel_uncore_forcewake_get(dev_priv, FORCEWAKE_ALL); - if (dev_priv->ellc_size) + if (dev_priv->ellc_size && INTEL_GEN(dev_priv) < 9) I915_WRITE(HSW_IDICR, I915_READ(HSW_IDICR) | IDIHASHMSK(0xf)); if (IS_HASWELL(dev)) -- GitLab
