Bug#899211: linux-cpupower: linuxcpupower unable to call hardware to tell current frequency

[shirish शिरीष <shirishag75@gmail.com>]

Package: linux-cpupower
Version: 4.16.5-1
Severity: normal

Dear Maintainer,

I was running -

$ cpupower frequency-info
analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 800 MHz - 3.30 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 800 MHz and 3.30 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 3.21 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes

Now as can be seen it says 'current CPU frequency: Unable to call
hardware' but when it is set to performance, then it should tell what
frequency it is using now.

Some info. of the current machine -
