drm/i915/uc: Make GuC/HuC fw fetch and loading functions/file structure symmetric

2018-03-02T09:04:45Z

GuC load function is named intel_guc_fw_upload() and HuC load function is named intel_huc_init_hw(). Make them consistent intel_*_fw_upload. Also move HuC fw loading functions and declarations to separate files intel_huc_fw.c|h like GuC. While at this, do below changes 1. Update kernel-doc comment for intel_*_fw_upload() functions 2. s/huc_ucode_xfer/huc_fw_xfer 3. Introduce intel_huc_fw_init_early() v2: Changed patch to update HuC functions instead of changing guc_fw_upload and update file structure. (Michal Wajdeczko) v3: Added SPDX License identifier to huc_fw.c|h.

drm/i915/huc: Load HuC only if requested

2017-12-06T14:41:54Z

Our new "enable_guc" modparam allows to control whenever HuC should be loaded. However existing code will try load and authenticate HuC always when we use the GuC. This patch is trying to enforce modparam selection. v2: no need to cast PTR_ERR (Chris) fetch/fini only if required (Michal) fix wrong break (Sagar) v3: add new goto label (Sagar) Signed-off-by: Michal Wajdeczko Cc: Chris Wilson Cc: Joonas Lahtinen Cc: Sagar Arun Kamble Reviewed-by: Sagar Arun Kamble Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20171206135316.32556-7-michal.wajdeczko@intel.com

drm/i915/huc: Move firmware selection to init_early

2017-12-06T14:41:46Z

Doing HuC firmware path selection from sanitize_options function is not perfect, while there is no problem with doing so during early init stage as we already have all needed data.

Fix includes order and make sure we only include required headers. While here, make intel_huc.h header self-contained.
