The problem with chrome is that it is split in more than 2 processes(often 3 processes)  

and I don’t know if is a possibility to join the power info for all of them into one.

Also ,

for  sections : GPU ops/s

Disk IO/s

GFX

, the information is missing for chrome --type=gpu-process, and chrome --type=renderer

Thanks

Hi Marius,

That is not an error, The message tells that PowerTOP has not saved values as baseline.   But you still can run the program. 

You could run it  using:

1- To generate an html file: powertop - -html

2- From the command line: powertop

I executed PowerTOP on Ubuntu running chrome  and got the attached file.

I would recommend to join and post other your questions to the mailing list so that other people can benefit.

Thank you,

Alexandra.
