Subject: [PATCH RESEND] cpupower: Fix no-rounding MHz frequency output
Date: Mon, 23 Oct 2017 07:56:32 -0400 [thread overview]
Message-ID: <20171023115632.27998-1-prarit@redhat.com> (raw)
Sent about a year ago ...

'cpupower frequency-info -ln' returns kHz values on systems with MHz range
minimum CPU frequency range. For example, on a 800MHz to 4.20GHz system
the command returns
hardware limits: 800000 MHz - 4.200000 GHz
The value of speed passed into print_speed is in kHz, so divide speed by
1000 in the MHz else-if section to get MHz.
