Hi. We want to try changing the clock frequency numbers for the gpu in the device tree (msm8996.dtsi). We see this for the gpu:
/* This is a safe speed for bring up in all bin levels.
* This isn’t the fastest the chip can go, but we can
* get there eventually */
compatible = “qcom,gpu-pwrlevels”;
qcom,gpu-freq = <510000000>;
qcom,gpu-freq = <27000000>;
What is the range of values we can use. Is it a multiple of some number? Is the one frequency number(510000000) the upper boundary and the other number(270000000) a lower boundary?
Also, can someone tell me if the GPU is dynamically changing clock speed? Can we read the GPU clock speed somehow?
