What is a PM-triggered change of gpu freq? Do you mean when the hw
itself throttles depending on thermal load. Then no. Best you can do is
Hi,
is there a simple way for user space to trace PM-triggered changes of
GPU frequency on GEN9/Skylake?
i915:intel_gpu_freq_change seems to only report SW-triggered frequency
change requests. The best option I currently see is to poll
gt_act_freq_mhz, but I was hoping for a more elegant solutio
