The DTPM framework is looking for upstream SoC candidates to share the power numbers. We can see around different numbers but the one which seems to be consistent with the initial post for the values on the CPUs can be found in the patch https://lore.kernel.org/patchwork/patch/810159/ I don't know the precision of this value but it is better than nothing. Hopefully, one day SoC vendors will be more generous with the power numbers at least for the SoC which are from the previous generation and give the community the opportunity to develop power based frameworks. --- arch/arm64/boot/dts/rockchip/rk3399.dtsi | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/boot/dts/rockchip/rk3399.dtsi b/arch/arm64/boot/dts/rockchip/rk3399.dtsi index edbbf35fe19e..1ab1d293d2e9 100644 --- a/arch/arm64/boot/dts/rockchip/rk3399.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3399.dtsi @@ -1933,6 +1933,7 @@ interrupt-names = "job", "mmu", "gpu"; clocks = <&cru ACLK_GPU>; #cooling-cells = <2>; + dynamic-power-coefficient = <977>; power-domains = <&power RK3399_PD_GPU>; status = "disabled"; }; -- 2.17.1
