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

== 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.
