I'm on the current stable kernel, 5.3.8. enable_guc is -1, which on this
platform should be equivalent to 2. 5.3 only accepts guc 32.0.3 and huc 02

[drm] HuC: Loaded firmware i915/kbl_huc_ver02_00_1810.bin (version 2.0)
[  116.266798] [drm] GuC: Loaded firmware i915/kbl_guc_32.0.3.bin (version
32.0)
[  116.266967] i915 0000:00:02.0: GuC firmware version 32.0
[  116.266968] i915 0000:00:02.0: GuC submission disabled
[  116.266969] i915 0000:00:02.0: HuC enabled
