From 8620eb1dbbf287694ee8e0cd280fadedb1f91012 Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Wed, 6 Dec 2017 13:53:14 +0000 Subject: [PATCH] drm/i915/uc: Don't use -EIO to report missing firmware -EIO has special meaning and is used when we want to allow engine initialization to fail and mark GPU as wedged. However here at this function we should return error code that corresponds to upload status only, as any decision how to handle missing firmware should be done higher level function (silent fallback to non-GuC mode, fail into wedged mode, or abort driver load with fatal error). v2: commit message update (Michal) Signed-off-by: Michal Wajdeczko Cc: Chris Wilson Cc: Joonas Lahtinen Cc: Sagar Arun Kamble Reviewed-by: Chris Wilson Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20171206135316.32556-5-michal.wajdeczko@intel.com --- drivers/gpu/drm/i915/intel_uc_fw.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_uc_fw.c b/drivers/gpu/drm/i915/intel_uc_fw.c index b376dd3b28cc..784eff9cdfc8 100644 --- a/drivers/gpu/drm/i915/intel_uc_fw.c +++ b/drivers/gpu/drm/i915/intel_uc_fw.c @@ -214,7 +214,7 @@ int intel_uc_fw_upload(struct intel_uc_fw *uc_fw, intel_uc_fw_type_repr(uc_fw->type), uc_fw->path); if (uc_fw->fetch_status != INTEL_UC_FIRMWARE_SUCCESS) - return -EIO; + return -ENOEXEC; uc_fw->load_status = INTEL_UC_FIRMWARE_PENDING; DRM_DEBUG_DRIVER("%s fw load %s\n", -- GitLab
