Hey hey, when running the linux-rt-bfq kernel is it still possible to set/scale the frequency of a cpu like this: cpupower -c all frequency-set -g schedutil and back using the "performance" model or similar?

Hi, I don't know if bfq makes sense in a rt kernel context and I've got no idea, if cpupower is a reliable tool. However, after downloading the tarball of the kernel from the AUR, extracting the config and searching for CONFIG_CPU_FREQ, I wonder why you ask, since all governors are available. Regards, Ralf
