As I suspected, on your system all the performance levels are the same: [ 8.961675] == power state 0 == [ 8.961677] ui class: none [ 8.961679] internal class: boot [ 8.961682] caps: video [ 8.961684] uvd vclk: 0 dclk: 0 [ 8.961686] power level 0 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961688] power level 1 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961690] power level 2 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961691] status: c r b [ 8.961695] == power state 1 == [ 8.961696] ui class: performance [ 8.961698] internal class: none [ 8.961700] caps: video [ 8.961703] uvd vclk: 0 dclk: 0 [ 8.961704] power level 0 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961706] power level 1 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961708] power level 2 sclk: 45000 mclk: 50000 vddc: 950 [ 8.961709] status: So there is no dynamic switching supported on your system.
