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.
