[Bug 1732865] Re: [LTCTest][OPAL][FW860.20] lscpu failed to list cpu max and min frequencies

 

OK, I checked it myself now, bionic + artful are OK, so all we need is
the backport to xenial.

** Also affects: util-linux (Ubuntu Artful)
   Importance: Undecided
       Status: New

** Changed in: util-linux (Ubuntu Artful)
       Status: New => Fix Released

Bug description:
  [Test case]
  1. Clone https://github.com/open-power/op-test-framework
  2. Run this command to GUARD the cpu.
  ./op-test --bmc-type FSP --bmc-ip $FSPIP --bmc-username dev --bmc-password FipSdev --host-ip $HOSTIP --host-user root --host-password passw0rd --ffdcdir test-reports/ --run testcases.OpTestHMIHandling.MalfunctionAlert
  3. Repeat again, so that multiple CPUs are guarded.
  4. Run lscpu
  5. Observe that no CPU frequencies are displayed:
  CPU max MHz: (null)
  CPU min MHz: (null)
  6. Install util-linux from -proposed.
  7. Run lscpu again
  8. Observe that max and min CPU frequencies are correctly displayed.

  ---Problem Description---
  After 3 CPU's are garded, lscpu failed to list CPU max and min frequencies

  Contact Information = ppaidipe@xxxxxxxxxx

  ---uname output---
  Linux p8wookie 4.8.0-32-generic #34~16.04.1-Ubuntu SMP Tue Dec 13 17:01:57 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux

  Machine Type = PowerNV 8284-22A

  ---Debugger---
  A debugger is not configured

  ---Steps to Reproduce---
   1. Read lscpu output
  2. Inject HMI Non recoverable error three times
  3. Read lscpu output again
  compare the output cpu frequencies will list as NULL

  Stack trace output:
   no

  Oops output:
   no

  Not able to recreate this issue, I am facing some other issue while injecting HMI Non recoverable error

  Pridhivi,
  Can you please provide steps to reproduce with the commands

  == Comment: #4 - Pridhiviraj Paidipeddi <ppaidipe@xxxxxxxxxx> - 2017-02-10 02:04:56 ==
  Hi Mamatha
  I am able to reproduce with below steps.

  On Host:
  #lscpu
  #service kdump-tools stop
  #echo 10 > /proc/sys/kernel/panic

  On FSP:
  $ getscom pu.ex 10013100 -all
  $ putscom pu.ex 10013100 1000000000000000 -n0 -p00 -c6

  Repeat the above process 4 times with each time on a different chip
  with master core getting injected.

  Then run

  Hi Pridhivi,

  I have fixed the issue and copied "lscpu" on the p8wookie system,
  Can you please verify and update the bug, so that I will submit patch for review

  Thanks

      lscpu: Read available CPUs max and min frequencies

      Problem:"lscpu frequency-info" command was always reading CPU0
      max and min frequencies. If CPU0 is guarded or offline then it used to
      display max and min frequencies as NULL.

      This patch will read overall CPU max and min frequencies.
