Thermald 1.9.1-1ubuntu0.4 contains the backport of the adaptive engine,
see bug https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1913186
Thermald 1.9.1-1ubuntu.05 contains the following fixes that may also be
useful:
- Disable legacy rapl cdev when rapl-mmio is in use
This will prevent PL1/PL2 power limit from MSR based rapl, which
may not be the correct one.
- Delete all trips from zones before psvt install
Initially zones has all the trips from sysfs, which may have wrong
settings. Instead of deleting only for matched psvt zones, delete
or all zones. In this way only zones which are in PSVT will be
present.
- Check for alternate names for B0D4 device
B0D4 can be named as TCPU or B0D4. So search for both names
if failed to find one.
- Fix error for condition names
The current code caps the max name as the last condition name,
which is "Power_Slider". So any condition more than 56 will be
printing error, with "Power_Slider" as condition name. For example
for condition = 57: Unsupported condition 57 (Power_slider)
- Set a very high RAPL MSR PL1 with --adaptive
After upgrading Dell Latitude 5420, again noticed performance
degradation.
The PPCC power limit for MSR RAPL PL1 is reduced to 15W. Even though
we disable MSR RAPL with --adaptive option, it is not getting
disabled. So MSR RAPL limits still playing role.
To fix that set a very high MSR RAPL PL1 limit so that it never
causes throttling. All throttling with --adaptive option is done
using RAPL-MMIO.
- Special case for default PSVT
When there are no adaptive tables and only one default PSVT table
is present with just one entry with MAX type. Add one additional
entry as done for non default case.
- Increase power limit for disabled RAPL-MMIO
Increase 100W to 200W as some desktop platform already have limit
more than 100W.
- Use Adaptive PPCC limits for RAPL MMIO
Set the correct device name as RAPL-MSR so that RAPL-MMIO can
also set the correct default power limits.
So first step is to see if thermald 1.9.1-1ubuntu0.5 helps.

Title:
CPU frequency stuck at minimum value
Status in linux package in Ubuntu:
Confirmed
Status in thermald package in Ubuntu:
Incomplete
Bug description:
I installed the Kubuntu variant of Ubuntu 18.04 on a new HP Spectre 13
laptop. Performance is poor. The CPU (an i7-8550U) is running at
400MHz, and never speeds up, even when running some of the Phoronix
Test Suite benchmarks.
I can use cpupower to switch to the "performance" cpufreq governor,
but cannot change the frequency with either governor.
Here is the output of some experiments I ran while Phoronix's c-ray test was
running.

- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
