From d2be9f2f41a8e361def96f8ca3eebf2db1c280a5 Mon Sep 17 00:00:00 2001 From: Arkadiusz Hiler Date: Tue, 14 Mar 2017 15:28:10 +0100 Subject: [PATCH] drm/i915/guc: Extract param logic form guc_init_fw() Let intel_guc_init_fw() focus on determining and fetching the correct firmware. This patch introduces intel_uc_sanitize_options() that is called from intel_sanitize_options(). Then, if we have GuC, we can call intel_guc_init_fw() conditionally and we do not have to do the internal checks. v2: fix comment, notify when nuking GuC explicitly enabled (M. Wajdeczko) v3: fix comment again, change the nuke message (M. Wajdeczko) v4: update title to reflect new function name + rebase v5: text && remove 2 uneccessary checks (M. Wajdeczko) Cc: Michal Winiarski Cc: Michal Wajdeczko Cc: Daniele Ceraolo Spurio Cc: Joonas Lahtinen Signed-off-by: Arkadiusz Hiler Reviewed-by: Joonas Lahtinen Signed-off-by: Joonas Lahtinen --- drivers/gpu/drm/i915/i915_drv.c | 2 ++ drivers/gpu/drm/i915/intel_guc_loader.c | 18 +--------------- drivers/gpu/drm/i915/intel_huc.c | 3 --- drivers/gpu/drm/i915/intel_uc.c | 28 ++++++++++++++++++++++++- drivers/gpu/drm/i915/intel_uc.h | 1 + 5 files changed, 31 insertions(+), 21 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index 8a456ec52019..9164167cd147 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -988,6 +988,8 @@ static void intel_sanitize_options(struct drm_i915_private *dev_priv) i915.semaphores = intel_sanitize_semaphores(dev_priv, i915.semaphores); DRM_DEBUG_DRIVER("use GPU semaphores? %s\n", yesno(i915.semaphores)); + + intel_uc_sanitize_options(dev_priv); } /** diff --git a/drivers/gpu/drm/i915/intel_guc_loader.c b/drivers/gpu/drm/i915/intel_guc_loader.c index 3a37d14587a3..e732266fd610 100644 --- a/drivers/gpu/drm/i915/intel_guc_loader.c +++ b/drivers/gpu/drm/i915/intel_guc_loader.c @@ -534,20 +534,7 @@ void intel_guc_init_fw(struct intel_guc *guc) struct drm_i915_private *dev_priv = guc_to_i915(guc); const char *fw_path; - if (!HAS_GUC(dev_priv)) { - i915.enable_guc_loading = 0; - i915.enable_guc_submission = 0; - } else { - /* A negative value means "use platform default" */ - if (i915.enable_guc_loading < 0) - i915.enable_guc_loading = HAS_GUC_UCODE(dev_priv); - if (i915.enable_guc_submission < 0) - i915.enable_guc_submission = HAS_GUC_SCHED(dev_priv); - } - - if (!HAS_GUC_UCODE(dev_priv)) { - fw_path = NULL; - } else if (IS_SKYLAKE(dev_priv)) { + if (IS_SKYLAKE(dev_priv)) { fw_path = I915_SKL_GUC_UCODE; guc->fw.major_ver_wanted = SKL_FW_MAJOR; guc->fw.minor_ver_wanted = SKL_FW_MINOR; @@ -567,9 +554,6 @@ void intel_guc_init_fw(struct intel_guc *guc) guc->fw.fetch_status = INTEL_UC_FIRMWARE_NONE; guc->fw.load_status = INTEL_UC_FIRMWARE_NONE; - /* Early (and silent) return if GuC loading is disabled */ - if (!i915.enable_guc_loading) - return; if (fw_path == NULL) return; if (*fw_path == '\0') diff --git a/drivers/gpu/drm/i915/intel_huc.c b/drivers/gpu/drm/i915/intel_huc.c index fda473db317e..168aab1e15da 100644 --- a/drivers/gpu/drm/i915/intel_huc.c +++ b/drivers/gpu/drm/i915/intel_huc.c @@ -162,9 +162,6 @@ void intel_huc_init_fw(struct intel_huc *huc) huc->fw.load_status = INTEL_UC_FIRMWARE_NONE; huc->fw.fw = INTEL_UC_FW_TYPE_HUC; - if (!HAS_HUC_UCODE(dev_priv)) - return; - if (IS_SKYLAKE(dev_priv)) { fw_path = I915_SKL_HUC_UCODE; huc->fw.major_ver_wanted = SKL_HUC_FW_MAJOR; diff --git a/drivers/gpu/drm/i915/intel_uc.c b/drivers/gpu/drm/i915/intel_uc.c index e5155deee69e..f0a69d4388bb 100644 --- a/drivers/gpu/drm/i915/intel_uc.c +++ b/drivers/gpu/drm/i915/intel_uc.c @@ -26,6 +26,27 @@ #include "intel_uc.h" #include +void intel_uc_sanitize_options(struct drm_i915_private *dev_priv) +{ + if (!HAS_GUC(dev_priv)) { + if (i915.enable_guc_loading > 0) + DRM_INFO("Ignoring GuC options, no hardware"); + + i915.enable_guc_loading = 0; + i915.enable_guc_submission = 0; + } else { + /* A negative value means "use platform default" */ + if (i915.enable_guc_loading < 0) + i915.enable_guc_loading = HAS_GUC_UCODE(dev_priv); + if (i915.enable_guc_submission < 0) + i915.enable_guc_submission = HAS_GUC_SCHED(dev_priv); + + /* Can't enable guc submission without guc loaded */ + if (!i915.enable_guc_loading) + i915.enable_guc_submission = 0; + } +} + void intel_uc_init_early(struct drm_i915_private *dev_priv) { mutex_init(&dev_priv->guc.send_mutex); @@ -33,7 +54,12 @@ void intel_uc_init_early(struct drm_i915_private *dev_priv) void intel_uc_init_fw(struct drm_i915_private *dev_priv) { - intel_huc_init_fw(&dev_priv->huc); + if (!i915.enable_guc_loading) + return; + + if (HAS_HUC_UCODE(dev_priv)) + intel_huc_init_fw(&dev_priv->huc); + intel_guc_init_fw(&dev_priv->guc); } diff --git a/drivers/gpu/drm/i915/intel_uc.h b/drivers/gpu/drm/i915/intel_uc.h index 26d5c6aab9c1..c5179efe2db9 100644 --- a/drivers/gpu/drm/i915/intel_uc.h +++ b/drivers/gpu/drm/i915/intel_uc.h @@ -184,6 +184,7 @@ struct intel_huc { }; /* intel_uc.c */ +void intel_uc_sanitize_options(struct drm_i915_private *dev_priv); void intel_uc_init_early(struct drm_i915_private *dev_priv); void intel_uc_init_fw(struct drm_i915_private *dev_priv); void intel_uc_prepare_fw(struct drm_i915_private *dev_priv, -- 2.39.5
