[Bug 1480349] Re: thermald breaks frequency scaling in Xeon® E5-2687W v3 & E5-1650 v3

[Colin Ian King]

The bionic SRU test message occurred because I accidentally uploaded the
package with the entire old history.  This bug has already been fixed
and the verification for bionic can be ignored.

[Andy Whitcroft]

Hello Shahar, or anyone else affected,

Accepted thermald into bionic-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/thermald/1.7.0-5ubuntu4 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

I've given this a run through on a bunch of Wily based intel systems and
can't see any regressions, I therefore mark this as verified for wily.

Re: comment #85, I do not believe this is a regression based on this
fix.  With the view that the same fix landed on Xenial and Trusty and
it's the same code base, I'd like this bug to be released if possible.

- 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?
