When I boot with this installed frequency scaling is no longer behaving as expected.
It seems that with this installed, the OS loses control of the scaling.
It seems that scaling is performed, though. And very much to the purpose of power saving.
Performance is terrible because of this. And I do mean terrible.
It makes it so that there are two governors available, powersave and performance.
And I can seemingly switch between them, but setting performance (yes, on all cores) doesn't seem to change to scaling behavior. The frequency doesn't pass 800MHz.
I would like to use Intel's microcode updates, but I have to have my CPU running at the speed for which it costs so damn much.
Any suggestions?

SRU Justification Wily
CPU scaling on a class of Intel CPUs is not functioning correctly, causing the CPU to be throttled back to the lowest CPU frequency
[FIX]
Upstream cherry picks, as recommended by Intel
f4e316ef4d8d8c9a558ef5bfa74e25303c46a985 ("Add white list of the cpu ids")
18d1574230c6b9b4e8876c0b6739c074a24205e6 ("Move parser init to thd_engine")
6749427098434ccad81fa8c5f2a3e102fc1644f7 ("Remove wild card for loading")
ba4fe1e7bb77d09530544cda860fba559603ec83 ("Error recovery when sysfs attrib read fails")
Plus 4 changes to allow clean and simpler patching of the above 4 fix to reduce the risk of breaking thermald with a complex backport:
Remove trailing ':' from THD engine failure message
Remove !! from "No coretemp sysfs found"
Add new option for config file
Support target state
Essentially we now have a white list of valid CPUs to run thermald on, so we can exclude the issues on a wider class of CPUs.
[TEST CASE]
With the buggy thermald, CPU is pegged at the lowest CPU frequency. With the fixed thermald, CPU scaling now works.

[REGRESSION POTENTIAL]
We are allowing thermald now to run on a strict set of CPUs, so we are hoping that the whitelist covers the class that we can legitimately run thermald against.

SRU Justification Wily
CPU scaling on a class of Intel CPUs is not functioning correctly, causing the CPU to be throttled back to the lowest CPU frequency
[FIX]
Upstream cherry picks, as recommended by Intel
f4e316ef4d8d8c9a558ef5bfa74e25303c46a985 ("Add white list of the cpu ids")
18d1574230c6b9b4e8876c0b6739c074a24205e6 ("Move parser init to thd_engine")
6749427098434ccad81fa8c5f2a3e102fc1644f7 ("Remove wild card for loading")
ba4fe1e7bb77d09530544cda860fba559603ec83 ("Error recovery when sysfs attrib read fails")
Plus 4 changes to allow clean and simpler patching of the above 4 fix to reduce the risk of breaking thermald with a complex backport:
Remove trailing ':' from THD engine failure message
Remove !! from "No coretemp sysfs found"
Add new option for config file
Support target state
Essentially we now have a white list of valid CPUs to run thermald on, so we can exclude the issues on a wider class of CPUs.
[TEST CASE]
With the buggy thermald, CPU is pegged at the lowest CPU frequency. With the fixed thermald, CPU scaling now works.
[REGRESSION POTENTIAL]
We are allowing thermald now to run on a strict set of CPUs, so we are hoping that the whitelist covers the class that we can legitimately run thermald against.
--------------------------------------------------------------------------
When I boot with this installed frequency scaling is no longer behaving as expected.
It seems that with this installed, the OS loses control of the scaling.
It seems that scaling is performed, though. And very much to the purpose of power saving.
Performance is terrible because of this. And I do mean terrible.
The default governor is powersave.
Setting the governor to performance (yes, on all cores) doesn't seem to change to scaling behavior. The frequency doesn't pass 800MHz.
I would like to use Intel's microcode updates, but I have to have my CPU running at the speed for which it costs so damn much.
Any suggestions?
