From: Carlos Santa Date: Wed, 17 Aug 2016 19:30:56 +0000 (-0700) Subject: drm/i915: Make HWS_NEEDS_PHYSICAL the exception X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3177659a41cc4362cb740c24a982c2097962eb1b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Make HWS_NEEDS_PHYSICAL the exception Make the .hws_needs_physical the exception by switching the flag on earlier platforms since they are fewer to support. Remove the flag on later GPUs hardware since they all use GTT hws by default. Switch the logic as well in the driver to reflect this change Signed-off-by: Carlos Santa Reviewed-by: Rodrigo Vivi Signed-off-by: Rodrigo Vivi --- diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index fcba6fe3caaf..755799e06a21 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -639,7 +639,7 @@ struct intel_csr { func(is_i915g) sep \ func(is_i945gm) sep \ func(is_g33) sep \ - func(need_gfx_hws) sep \ + func(hws_needs_physical) sep \ func(is_g4x) sep \ func(is_pineview) sep \ func(is_broadwater) sep \ @@ -2748,7 +2748,7 @@ struct drm_i915_cmd_table { #define HAS_EDRAM(dev) (!!(__I915__(dev)->edram_cap & EDRAM_ENABLED)) #define HAS_WT(dev) ((IS_HASWELL(dev) || IS_BROADWELL(dev)) && \ HAS_EDRAM(dev)) -#define I915_NEED_GFX_HWS(dev) (INTEL_INFO(dev)->need_gfx_hws) +#define HWS_NEEDS_PHYSICAL(dev) (INTEL_INFO(dev)->hws_needs_physical) #define HAS_HW_CONTEXTS(dev) (INTEL_INFO(dev)->has_hw_contexts) #define HAS_LOGICAL_RING_CONTEXTS(dev) (INTEL_INFO(dev)->has_logical_ring_contexts) diff --git a/drivers/gpu/drm/i915/i915_gpu_error.c b/drivers/gpu/drm/i915/i915_gpu_error.c index d45a959b7c53..334f15df7c8d 100644 --- a/drivers/gpu/drm/i915/i915_gpu_error.c +++ b/drivers/gpu/drm/i915/i915_gpu_error.c @@ -1025,7 +1025,7 @@ static void error_record_engine_registers(struct drm_i915_error_state *error, if (INTEL_GEN(dev_priv) > 2) ee->mode = I915_READ_MODE(engine);
