Bug Description
== Comment: #0 - PAVAMAN SUBRAMANIYAM <email address hidden> - 2017-06-29 02:30:22 ==
---Problem Description---
cpupower monitor shows multiple stop Idle_Stats
---uname output---
Linux zz376p1 4.10.0-26-generic #30~16.04.1-Ubuntu SMP Tue Jun 27 09:38:48 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux
Machine Type = P9
---Debugger---
A debugger is not configured
---Steps to Reproduce---
Install a P9 8375-42A Hardware with Ubuntu 16.04.3 OS.
Then execute the cpupower monitor command to fetch all the Idle_Stats values.
root@zz376p1:~# cpupower monitor

As can be seen it shows 2 columns for stop.

cpu monitor will print the results of all the 3 available idle_stats .
The first stop -> stop0_lite stats
and
The second stop -> stop1_lite stats.
cpupower monitor header prints the header list by getting the name of the idle stats.
name (name description)
snoo [T] -> snooze
stop [T] -> stop0_lite
stop [T] -> stop1_lite
We can change the header to be more meaningful so user won't interpret it as 2 columns for stop.
May be we need to change the code to print the header to use name description instead of name.
.
I will work on the patch and get it resolve.

I have executed the command again with the fixed cpupower utility.
Submitted patch upstream and awaiting response.

The patch described in comment #6 has landed upstream in 4.18, so the next step would be to backport to 4.15 Ubuntu kernel so that it was available in the 16.04.5 HWE kernel.

I built a test kernel with commit f9652d5cae0. The test kernel can be downloaded from:
http://
Can you test this kernel and see if it resolves this bug?
Note about installing test kernels:
* If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages.
* If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-
Thanks in advance!

Assuming the fix in comment #13 is OK, it should be available in the Bionic general kernel (and its derivatives, include xenial-hwe) in the March 4th SRU release.

@PAVAMAN: Is there a reason that you installed the modules and modules-extra packages using 'dpkg -i' and then tried to install the kernel using 'apt-get install'? It doesn't look like you installed the right kernel there.
I think the third command should have been 'dpkg -i linux-image-
Please try to install the kernel that way and retry the test. Thanks

@<email address hidden>: Thanks for that test. Unfortunately I'm not quite sure why the patch isn't fixing the problem. This was the patch that IBM submitted upstream and reported that it fixes the problem. The patch applied cleanly to bionic. I'm still investigating this further and may require your help in testing it again if I can't reproduce the issue myself. Will update again shortly.
Thanks.

@<email address hidden>: Hello. Now I have a theory as to what the problem might be.
The upstream fix is actually a change only to the 'cpupower' tool, not the kernel itself. This tool is not part of the linux-image or linux-modules .deb files. It is built as part of the linux-tools .deb, which for some reason, wasn't included in the test build that I prepared for you.
I've updated the above link by adding the file: linux-tools-
This .deb includes the updated cpupower binary. The full path after installation should be: /usr/lib/
Please install that .deb and use the included 'cpupower' binary when testing.
Thank you.
