From 249fc7056104113633215106ac085b505d8dc161 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 21 Mar 2012 14:35:14 -0700 Subject: [PATCH] i965: When the kernel lacks the LLC check, assume it's present on gen >= 6. The param wasn't added until drm-intel-next for 3.4, so we were missing our various LLC fast-paths. --- src/mesa/drivers/dri/intel/intel_screen.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/src/mesa/drivers/dri/intel/intel_screen.c b/src/mesa/drivers/dri/intel/intel_screen.c index 6344d98a319..e823792ff93 100644 --- a/src/mesa/drivers/dri/intel/intel_screen.c +++ b/src/mesa/drivers/dri/intel/intel_screen.c @@ -770,9 +770,13 @@ __DRIconfig **intelInitScreen2(__DRIscreen *psp) intelScreen->hw_must_use_separate_stencil = intelScreen->gen >= 7; intelScreen->dri2_has_hiz = INTEL_DRI2_HAS_HIZ_UNKNOWN; - intelScreen->hw_has_llc = - intel_get_boolean(intelScreen->driScrnPriv, - I915_PARAM_HAS_LLC); + int has_llc = 0; + bool success = intel_get_param(intelScreen->driScrnPriv, I915_PARAM_HAS_LLC, + &has_llc); + if (success && has_llc) + intelScreen->hw_has_llc = true; + else if (!success && intelScreen->gen >= 6) + intelScreen->hw_has_llc = true; intel_override_separate_stencil(intelScreen); -- 2.30.2
