Re: [lkp] [drm/i915/huc] 0a9a963e36: [drm:intel_uc_fw_fetch [i915]] *ERROR* Failed to fetch GuC firmware from i915/skl_huc_ver01_07_1398.bin (error -2)

[Peter Antoine]

Yes, this line:
*ERROR* Failed to fetch HuC firmware from i915/skl_huc_ver01_07_1398.bin

means that it failed to find the firmware.

If you are using the HuC (only require for some extra media codecs) then 
you may need to update libraries as well as installing the firmware. If 
you are just testing the patches then you can just ignore this error.
