When SLPC is controlling frequency requests, RPS state related to autotuning is no longer valid. Make user aware through banner upfront. Value read from register RPNSWREQ likely has the frequency requested last by GuC SLPC. v1: Replace HAS_SLPC with intel_slpc_active (Paulo) Avoid magic numbers (Nick) Use a function for repeated code (Jon) v2: Add "SLPC Active" to i915_frequency_info output and don't update cur_freq as it is driver internal request. (Chris) v3: Removing sysfs interface gt_req_freq_mhz out of this patch for proper division of functionality. (Sagar) v4: idle_freq, boost_freq are also not used with SLPC. v5: Added SLPC banner to i915_rps_boost_info and keep printing driver internal values. (Chris) v6: Commit message update.
