Hi, I know about jetson_clocks.sh & nvpmodel. I am wondering why nvhost_podgov does not automatically scale up the gpu frequency based on my application usage? Or rather, it does, but it takes ~15-20 minutes to do so. When the gpu is scaled down, my application runs at 1fps, when gpu is at max f…

hello jkeller, may i know how’s GPU loading that your application taken, you should be able to monitor that by running the tegrastats simultaneously. sudo ./tegrastats also, could you able to reproduce the GPU frequency not scaling issue. please execute the TRT example as following below, tha…

hello jkeller,

could you please try to request a locked GPU frequency following below,
thanks
