Package: powertop Version: 2.8-1+b1 Severity: minor Running powertop --auto_tune (on a desktop system) yields a lot of errors:
modprobe cpufreq_stats failedLoaded 0 prior measurements Cannot load from file /var/cache/powertop/saved_parameters.powertop File will be loaded after taking minimum number of measurement(s) with battery only RAPL device for cpu 0 RAPL device for cpu 0 Devfreq not enabled Cannot load from file /var/cache/powertop/saved_parameters.powertop File will be loaded after taking minimum number of measurement(s) with battery only unknown op '{' Leaving PowerTOP Especially the "unknown op" seems somewhat disturbing. Autotune makes sense on desktop-systems, too: Especially for powersavings for PCI devices. -- System Information: Debian Release: 9.5 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-7-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages powertop depends on: ii libc6 2.24-11+deb9u3 ii libgcc1 1:6.3.0-18+deb9u1 ii libncurses5 6.0+20161126-1+deb9u2 ii libncursesw5 6.0+20161126-1+deb9u2 ii libnl-3-200 3.2.27-2 ii libnl-genl-3-200 3.2.27-2 ii libpci3 1:3.5.2-1 ii libstdc++6 6.3.0-18+deb9u1 ii libtinfo5 6.0+20161126-1+deb9u2 powertop recommends no packages.
