Status in linux package in Ubuntu: In Progress Status in linux-oem-5.6 package in Ubuntu: New Status in linux-riscv package in Ubuntu: New Status in systemd package in Ubuntu: Invalid Status in linux source package in Focal: Triaged Status in linux-oem-5.6 source package in Focal: New Status in linux-riscv source package in Focal: New Status in systemd source package in Focal: Fix Released Status in linux source package in Groovy: In Progress Status in linux-oem-5.6 source package in Groovy: New Status in linux-riscv source package in Groovy: New Status in systemd source package in Groovy: Invalid Bug description: [Impact] * Kernel should have sensible default governor set to CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y for the generic, hwe, raspi, riscv64, oem kernel flavours in Focal and Groovy+. * ondemand.service must not be shipped by systemd package * ppc64el, kvm flavour, cloud-kernels flavours should continue using performance governor. * Users should be given control to rev-up to performance, or rev-down to powersave using other tools, i.e. game-mode and/or similar CLI or GUI tools (these are scheduled to be integrated on Ubuntu platform later). [Test Case] * Boot ubuntu generic, hwe, or oem kernel * Check that default governor is ondemand * Check that ondemand.service is not active [Regression Potential] * ondemand governor is the best kernel default as recently analyzed by colin king, it gives a balance bootspeed and power, giving as responsive machines whilst not wasting power. It is the best experience we can give our users by default. [Other Info] * It is up to the user to elect/switch to powersave for maximum battery life, or to the performance for maximum processing power (i.e. gaming / computation).
