We ensure that GuC is completely suspended and client is destroyed
in i915_gem_suspend during i915_driver_unload. So now intel_uc_fini_hw
should just take care of cleanup,
hence s/intel_uc_fini_hw/intel_uc_cleanup. Correspondingly
we also updated as s/i915_guc_submission_fini/i915_guc_submission_cleanup
Other functionality to disable communication, disable interrupts and
update of ggtt.invalidate is taken care by intel_uc_suspend.
With this patch we are also doing guc_free_load_err_log only
if i915.enable_guc_loading is set.
I'm not sure that commit message must stay immutable during whole
review process, as now contains misleading statement. With that fixed:
Reviewed-by: Michal Wajdeczko <michal.wajdec...@intel.com>
v2: Rebase w.r.t removal of GuC code restructuring.
v3: Removed intel_guc_cleanup. (Michal Wajdeczko)
v4: guc_free_load_err_log() needs to be called without checking
i915.enable_guc_loading as this param is cleared on failure.
