Why are we looking at focal now? The change to systemd only happened after the opening of groovy.
Data is tricky. There are a ton of different cpufreq drivers that are affected, and they all have different behavior. pstates alone has different behavior on newer intels that do pstates in hardware (hwp) vs those that do them in software. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.6 in Ubuntu. https://bugs.launchpad.net/bugs/1885730 Title: Please switch default, hwe, oem kernel flavours governor to CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y , such that advanced userspace utilities such as game-mode can be later used to rev-up to to performance, or rev-down to powersave. Status in linux package in Ubuntu: In Progress Status in linux-oem-5.6 package in Ubuntu: Confirmed Status in linux-riscv package in Ubuntu: Confirmed Status in linux source package in Focal: Triaged Status in linux-oem-5.6 source package in Focal: Confirmed Status in linux-riscv source package in Focal: Confirmed 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: Confirmed Status in linux-riscv source package in Groovy: Confirmed 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, riscv, oem kernel flavours in Focal and Groovy+. * ondemand.service must not be shipped by systemd package * 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).
