  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.

[Ubuntu Kernel Bot]

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-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

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.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 1719545] Re: [P9][LTCTest][Opal][FW910] cpupower monitor shows multiple stop Idle_Stats

[Khaled El Mously]

@sthou...@in.ibm.com: 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-4.15.0-46_4.15.0-46.49~k1_ppc64el.deb

This .deb includes the updated cpupower binary. The full path after
installation should be: /usr/lib/linux-tools-4.15.0-46/cpupower

Please install that .deb and use the included 'cpupower' binary when testing. 
Thank you.

[Kernel-packages] [Bug 1719545] Re: [P9][LTCTest][Opal][FW910] cpupower monitor shows multiple stop Idle_Stats

[Khaled El Mously]

@sthou...@in.ibm.com: 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.

[Kernel-packages] [Bug 1719545] Re: [P9][LTCTest][Opal][FW910] cpupower monitor shows multiple stop Idle_Stats

[Khaled El Mously]

@Pavaman, thanks for testing.

The patch that was submitted upstream by IBM to fix this bug (
f9652d5cae04eb5e85303c087f5842d320499c65 ) was applied (cleanly) to
bionic to generate that kernel. It's not clear to me why that doesn't
fix your problem since it was identified as the only required fix for
this issue.

Could you please try this kernel:
https://kernel.ubuntu.com/~kmously/1719545/kernel-kmously-438fd5a-TfNM/

and could you please also show the output of uname -a as well ?

Thanks

Your report is missing any confirmation that the bug is in fact fixed by
the test kernel. Could you please provide some additional comments here
stating if this kernel fixes the issue for you or not ?

[Kernel-packages] [Bug 1719545] Re: [P9][LTCTest][Opal][FW910] cpupower monitor shows multiple stop Idle_Stats

[Khaled El Mously]

@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-unsigned-4.15.0-45-generic_4.15.0-45.48~16.04.1_ppc64el.deb'

Please try to install the kernel that way and retry the test. Thanks

[Kernel-packages] [Bug 1719545] Re: [P9][LTCTest][Opal][FW910] cpupower monitor shows multiple stop Idle_Stats

[Joseph Salisbury]

I built a test kernel with commit f9652d5cae0.  The test kernel can be 
downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1719545

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-unsigned .deb packages.

Thanks in advance!

[Kernel-packages] [Bug 1719545] Re: [P9][LTCTest][Opal][FW910] cpupower monitor shows multiple stop Idle_Stats

[Andrew Cloke]

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.

  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

  ---Problem Description---
  cpupower monitor shows multiple stop Idle_Stats
   

   
  ---uname output---

  ---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

 8|2052|  15|  0.00|  0.00|  0.00

  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

  cpupower monitor header prints the header list by getting the name of
