From fc32de9358c0a7b6f7c4639a3a8056b10a9b7669 Mon Sep 17 00:00:00 2001 From: Dave Gordon Date: Thu, 18 Aug 2016 18:17:24 +0100 Subject: [PATCH] drm/i915/guc: revisit GuC loader message levels Some downgraded from DRM_ERROR() to DRM_WARN() or DRM_NOTE(), a few upgraded from DRM_INFO() to DRM_NOTE() or DRM_WARN(), and one eliminated completely. v2: different permutation of levels :) v3: convert a couple of "this shouldn't happen" messages to WARN() Signed-off-by: Dave Gordon Reviewed-by: Tvrtko Ursulin Signed-off-by: Tvrtko Ursulin --- drivers/gpu/drm/i915/intel_guc_loader.c | 34 ++++++++++++------------- 1 file changed, 17 insertions(+), 17 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_guc_loader.c b/drivers/gpu/drm/i915/intel_guc_loader.c index e67d8de427d0..853928f21596 100644 --- a/drivers/gpu/drm/i915/intel_guc_loader.c +++ b/drivers/gpu/drm/i915/intel_guc_loader.c @@ -152,12 +152,14 @@ static u32 get_gttype(struct drm_i915_private *dev_priv) static u32 get_core_family(struct drm_i915_private *dev_priv) { - switch (INTEL_INFO(dev_priv)->gen) { + u32 gen = INTEL_GEN(dev_priv); + + switch (gen) { case 9: return GFXCORE_FAMILY_GEN9; default: - DRM_ERROR("GUC: unsupported core family\n"); + WARN(1, "GEN%d does not support GuC operation!\n", gen); return GFXCORE_FAMILY_UNKNOWN; } } @@ -447,7 +449,7 @@ int intel_guc_setup(struct drm_device *dev) goto fail; } else if (*fw_path == '\0') { /* Device has a GuC but we don't know what f/w to load? */ - DRM_INFO("No GuC firmware known for this platform\n"); + WARN(1, "No GuC firmware known for this platform!\n"); err = -ENODEV; goto fail; } @@ -485,10 +487,8 @@ int intel_guc_setup(struct drm_device *dev) * that the state and timing are fairly predictable */ err = i915_reset_guc(dev_priv); - if (err) { - DRM_ERROR("GuC reset failed: %d\n", err); + if (err) goto fail; - } err = guc_ucode_xfer(dev_priv); if (!err) @@ -546,15 +546,15 @@ fail: else if (err == 0) DRM_INFO("GuC firmware load skipped\n"); else if (ret != -EIO) - DRM_INFO("GuC firmware load failed: %d\n", err); + DRM_NOTE("GuC firmware load failed: %d\n", err); else - DRM_ERROR("GuC firmware load failed: %d\n", err); + DRM_WARN("GuC firmware load failed: %d\n", err); if (i915.enable_guc_submission) { if (fw_path == NULL) DRM_INFO("GuC submission without firmware not supported\n"); if (ret == 0) - DRM_INFO("Falling back from GuC submission to execlist mode\n"); + DRM_NOTE("Falling back from GuC submission to execlist mode\n"); else DRM_ERROR("GuC init failed: %d\n", ret); } @@ -586,7 +586,7 @@ static void guc_fw_fetch(struct drm_device *dev, struct intel_guc_fw *guc_fw) /* Check the size of the blob before examining buffer contents */ if (fw->size < sizeof(struct guc_css_header)) { - DRM_ERROR("Firmware header is missing\n"); + DRM_NOTE("Firmware header is missing\n"); goto fail; } @@ -598,7 +598,7 @@ static void guc_fw_fetch(struct drm_device *dev, struct intel_guc_fw *guc_fw) css->key_size_dw - css->exponent_size_dw) * sizeof(u32); if (guc_fw->header_size != sizeof(struct guc_css_header)) { - DRM_ERROR("CSS header definition mismatch\n"); + DRM_NOTE("CSS header definition mismatch\n"); goto fail; } @@ -608,7 +608,7 @@ static void guc_fw_fetch(struct drm_device *dev, struct intel_guc_fw *guc_fw) /* now RSA */ if (css->key_size_dw != UOS_RSA_SCRATCH_MAX_COUNT) { - DRM_ERROR("RSA key size is bad\n"); + DRM_NOTE("RSA key size is bad\n"); goto fail; } guc_fw->rsa_offset = guc_fw->ucode_offset + guc_fw->ucode_size; @@ -617,14 +617,14 @@ static void guc_fw_fetch(struct drm_device *dev, struct intel_guc_fw *guc_fw) /* At least, it should have header, uCode and RSA.
