Parameter guc_log_level needs to be sanitized based on GuC support and
enable_guc_loading parameter since it depends on them like
enable_guc_submission. This will make GuC logging paths independent of
enable_guc_submission parameter in further patches.

Btw, I think the message "Ignoring GuC options, no hardware\n" is also
applicable when user specified guc_log_level>=0. Please update condition
that controls that message.
Yes. Will update that condition.

Looks good, but please also update condition in i915_guc_log_register()
as we may now rely only on sanitized guc_log_level:
void i915_guc_log_register(struct drm_i915_private *dev_priv)
{
if (!i915_modparams.enable_guc_submission ||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(i915_modparams.guc_log_level < 0))
return;
This is updated in the later patches in the series.
Also, maybe it is worth to update DOC in intel_guc_log.c and param
description in i915_params.c to indicate (obvious) dependency on guc.
Sure. Will add this.
Michal
