Steps:
------
1. Boot with kernel boot command lines:
i915.enable_guc_loading=2 i915.enable_guc_submission=2
2. Check GuC status:
dmesg |grep guc
Actual result:
--------------
2. GuC 9.14 does not load
Expected result:
----------------
2. GuC successfully loads

Reproduced (with our without the guc command lines) after I modified
drivers/gpu/drm/i915/i915_params.c like this:
struct i915_params i915 __read_mostly = {
…
.enable_guc_loading = -1,
.enable_guc_submission = -1,
.guc_log_level = -1,
…
};
module_param_named_unsafe(enable_guc_loading, i915.enable_guc_loading, int,
0400);
MODULE_PARM_DESC(enable_guc_loading,
"Enable GuC firmware loading "
"(-1=auto [default], 0=never, 1=if available, 2=required)");
module_param_named_unsafe(enable_guc_submission, i915.enable_guc_submission,
int, 0400);
MODULE_PARM_DESC(enable_guc_submission,
"Enable GuC submission "
"(-1=auto [default], 0=never, 1=if available, 2=required)");</pre>
