This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- artful' to 'verification-done-artful'. If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed- artful'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[Bug 1743269] Re: P-state not working in kernel 4.13
Submitted SRU request for Artful and Bionic:
https://lists.ubuntu.com/archives/kernel-team/2018-January/089416.html
** Description changed:
- I have a Lenovo Thinkpad X230 with an Intel Core i5-3210M CPU. I'm using
- Xubuntu 17.10 (Description:Ubuntu 17.10, Release: 17.10). I use tlp
- 1.0-1~artful in order to improve battery performance, particularly
- enabling the Intel P-state performance scaling. In Xubuntu 17.04 it
- worked flawlessly, but when I upgraded to 17.10 the processor doesn't
- scale anymore. I ran all the updates and it's not working. I also did a
- clean install using another hard drive and the problem persist.
+ == SRU Justification ==
+ Commits b29c6ef7bb12 and 7d5905dc14a8 fix a regression in Artful. They
+ were both added to mainline in v4.15-rc1 and fix the following two commits:
+ b29c6ef7bb12 Fixes: 4815d3c56d1e (cpufreq: x86: Make scaling_cur_freq behave
more as expected)
+ 7d5905dc14a8 Fixes: 890da9cf0983 (Revert "x86: do not use cpufreq_quick_get()
for /proc/cpuinfo "cpu MHz"")
+ According to the bug report, P-state is not working in Artful, but it was
working
+ in Zesty. This bug is happening on a Lenovo Thinkpad X230 with an Intel Core
i5-3210M CPU.
+ The bug reporter is using CPU scaling to improve battery life.
+
+ == Fixes ==
+ b29c6ef7bb12 ("x86 / CPU: Avoid unnecessary IPIs in arch_freq_get_on_cpu()")
+ 7d5905dc14a8 ("x86 / CPU: Always show current CPU frequency in /proc/cpuinfo")
+
+ == Regression Potential ==
+ Low. The two commit fix a current regression and have had additiona upstream
reviews
+ from being send to stable.

+
+ ## Original Bug Description ##
+ I have a Lenovo Thinkpad X230 with an Intel Core i5-3210M CPU. I'm using
Xubuntu 17.10 (Description: Ubuntu 17.10, Release: 17.10). I use tlp
1.0-1~artful in order to improve battery performance, particularly enabling the
Intel P-state performance scaling. In Xubuntu 17.04 it worked flawlessly, but
when I upgraded to 17.10 the processor doesn't scale anymore. I ran all the
updates and it's not working. I also did a clean install using another hard
drive and the problem persist.
I searched the tlp forums and similar problems pointed to a kernel bug,
so I'm filing this report.
I tested different mainline kernels in order to see what kernel version
is causing the problem:
Up to mainline kernel 4.12.14 generic, P-state scaling is OK
Kernel 4.13 generic up to kernel 4.14.12 generic, P-state scaling is not
working
Kernel 4.14.13 generic up to 4.15 rc7 generic, P-state scaling is OK
