'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 code that causes this error can be removed.  The next else if clause
will handle the output correctly such that

hardware limits: 800.000 MHz - 4.200000 GHz

is displayed correctly.

[v2]: Remove two lines instead of fixing broken code.

Thanks.  I will queue this up for 4.15-rc1.
OK

So are you going to maintain this utility going forward?
oops. I was on auto-pilot responding to patches sitting in my Inbox.
Wrong email response. Sorry about that.

Please ignore. Mu bad.
OK :-)

But that said, from my perspective, cpupower is basically not maintained.

Thomas, who sort of maintained it, but then basically became a patch
reviewer for it, does not respond to patches any more and I am not
sufficiently familiar with the code to be able to effectively review
the patches myself, nor I have the time to get more familiar with it.

For this reason, I'm inclined to drop this code from the kernel source
tree unless somebody steps in to fill the gap.
Please don't drop this from kernel sources.. I think this is useful. If you
are looking for a maintainer, I will be happy to step up to maintain it.


thanks,
