From: Chris Wilson Date: Thu, 4 Aug 2016 06:52:22 +0000 (+0100) Subject: drm/i915: Update GGTT initialisation functions to take drm_i915_private X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=97d6d7ab68e0b1f7268a5a69187c86305d65762f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Update GGTT initialisation functions to take drm_i915_private Since these are internal functions they operate on drm_i915_private and not the drm_device being passed in. So pass in the drm_i915_private instead, and remove one layer of dancing. No space wins here, just conforming to the norm in function parameters. v2: Include all the probe functions Signed-off-by: Chris Wilson Cc: Joonas Lahtinen Reviewed-by: Joonas Lahtinen Link: http://patchwork.freedesktop.org/patch/msgid/1470293567-10811-3-git-send-email-chris@chris-wilson.co.uk --- diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index 8996c2a6cd07..ed52f61d8560 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -1004,7 +1004,7 @@ static int i915_driver_init_hw(struct drm_i915_private *dev_priv) intel_sanitize_options(dev_priv); - ret = i915_ggtt_probe_hw(dev); + ret = i915_ggtt_probe_hw(dev_priv); if (ret) return ret; @@ -1022,11 +1022,11 @@ static int i915_driver_init_hw(struct drm_i915_private *dev_priv) goto out_ggtt; } - ret = i915_ggtt_init_hw(dev); + ret = i915_ggtt_init_hw(dev_priv); if (ret) return ret; - ret = i915_ggtt_enable_hw(dev); + ret = i915_ggtt_enable_hw(dev_priv); if (ret) { DRM_ERROR("failed to enable GGTT\n"); goto out_ggtt; @@ -1104,7 +1104,7 @@ static int i915_driver_init_hw(struct drm_i915_private *dev_priv) return 0; out_ggtt: - i915_ggtt_cleanup_hw(dev); + i915_ggtt_cleanup_hw(dev_priv); return ret; } @@ -1124,7 +1124,7 @@ static void i915_driver_cleanup_hw(struct drm_i915_private *dev_priv) pm_qos_remove_request(&dev_priv->pm_qos); arch_phys_wc_del(ggtt->mtrr); io_mapping_free(ggtt->mappable); - i915_ggtt_cleanup_hw(dev); + i915_ggtt_cleanup_hw(dev_priv); } /** @@ -1570,7 +1570,7 @@ static int i915_drm_resume(struct drm_device *dev) disable_rpm_wakeref_asserts(dev_priv); - ret = i915_ggtt_enable_hw(dev); + ret = i915_ggtt_enable_hw(dev_priv); if (ret) DRM_ERROR("failed to re-enable GGTT\n"); diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index 3df6b485d2d4..c4119ba5b69a 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -4543,7 +4543,7 @@ int i915_gem_init(struct drm_device *dev) intel_uncore_forcewake_get(dev_priv, FORCEWAKE_ALL); i915_gem_init_userptr(dev_priv); - i915_gem_init_ggtt(dev); + i915_gem_init_ggtt(dev_priv); ret = i915_gem_context_init(dev); if (ret) diff --git a/drivers/gpu/drm/i915/i915_gem_gtt.c b/drivers/gpu/drm/i915/i915_gem_gtt.c index 3fc77776d89b..39b3b36e8dea 100644 --- a/drivers/gpu/drm/i915/i915_gem_gtt.c +++ b/drivers/gpu/drm/i915/i915_gem_gtt.c @@ -2223,17 +2223,16 @@ void i915_ppgtt_release(struct kref *kref) kfree(ppgtt); } -extern int intel_iommu_gfx_mapped; /* Certain Gen5 chipsets require require idling the GPU before * unmapping anything from the GTT when VT-d is enabled. */ -static bool needs_idle_maps(struct drm_device *dev) +static bool needs_idle_maps(struct drm_i915_private *dev_priv) { #ifdef CONFIG_INTEL_IOMMU /* Query intel_iommu to see if we need the workaround.
