drm/i915/guc: Move firmware selection to init_early

2017-12-06T14:41:47Z

Doing GuC 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.

drm/i915: Add Guc/HuC firmware details to error state

2017-11-06T14:22:06Z

Include GuC and HuC firmware details in captured error state to provide additional debug information. To reuse existing uc firmware pretty printer, introduce new drm-printer variant that works with our i915_error_state_buf output. Also update uc firmware pretty printer to accept const input. v2: don't rely on current caps (Chris) dump correct fw info (Michal) v3: simplify capture of custom paths (Chris) v4: improve 'why' comment (Joonas) trim output if no fw path (Michal) group code around uc error state (Michal) v5: use error in cleanup_uc (Michal) Suggested-by: Chris Wilson Signed-off-by: Michal Wajdeczko Cc: Chris Wilson Cc: Joonas Lahtinen Link: https://patchwork.freedesktop.org/patch/msgid/20171026173657.49648-1-michal.wajdeczko@intel.com [ickle: allow printing uc_fw after allocation failure] Reviewed-by: Chris Wilson Signed-off-by: Chris Wilson

drm/i915/uc: Add pretty printer for uc firmware

2017-10-17T15:42:56Z

Debugfs for GuC and HuC load info have similar common part. Move and update dump of uc_fw to separate helper for reuse.

drm/i915: Update DMC firmware load error messages

2017-10-16T15:53:28Z

Some of the error messages from DMC load were too generic and may be confusing for the user. Lets explicitly add DMC words there. Also as homepage of DMC firmware is same as for the GuC and Huc, lets reuse URL definition.

With the code motion mostly done, convert all the uC code away from uint??_t at once (only a couple dozen variables), so that reading the checkpatch.pl output should actually pinpoint if a new uint??_t was accidentally introduced. v2: - Include intel_uc_fw.h too (Sagar) Signed-off-by: Joonas Lahtinen Cc: Michal Wajdeczko Cc: Chris Wilson Cc: Michał Winiarski Cc: Sagar Arun Kamble Cc: Anusha Srivatsa Cc: Sujaritha Sundaresan Reviewed-by: Sagar Arun Kamble Reviewed-by: Michal Wajdeczko Link: https://patchwork.freedesktop.org/patch/msgid/20171006084940.15910-1-joonas.lahtinen@linux.intel.com
