With commit fad2af195f1abaada473f4f9e9a554c1e4db768b PowerPlay was enabled by default for Carizzo, so I assumed this as complete and tested again. But I still get in dmesg this: [ powerplay ] this function not implement! [ powerplay ] min_core_set_clock not set There are multiple entries on startup and it happens occasional during runtime. Is PowerPlay on Carizzo still incomplete or is this a special problem with my system (HP ProBook 645 G2)? regards, Johannes
