It would seem that we are using uninitialized WOPCM variables when
setting the GuC pin bias. The pin bias has to be set after the WOPCM,
but before the call to i915_gem_contexts_init where the first contexts
are pinned so the safest place to set it seems to be right after
initializing the relevant variables in intel_wopcm_init.
Oops, do you have a Fixes?
Ha, it could be my fault: intel_wopcm_init and intel_uc_init_misc were
swapped in ("drm/i915/uc: Fetch GuC/HuC firmwares from guc/huc specific
init")
