** Summary changed:
- Bring back ondemand.service or switch kernel default governor for pstate -
pstate now defaults to performance governor
+ Please switch default kernel governor to ondemand, such that advanced
userspace utilities such as game-mode can be later used to rev-up to to
performance, or rev-down to powersave.
** Changed in: linux (Ubuntu Focal)

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.

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).
