ksysguardd: Avoid including IO-wait in CPU load.
Review Request #120406 - Created Sept. 28, 2014 and updated
IO-wait is included in the cpu usage. This is wrong since IO-wait is a part of the idle time. This goes for both total combines CPU-usage and the per CPU usage.
Fx. running a read from a slow USB-media like this will always end up showing 25% load on my system (I have 4 cores)
dd if=/dev/sdb of=/dev/null bs=1M
This end up being around 0% with my patch.
Hmm... there is no way to see the wait time anywhere then, right? I don't see a way to add individual columns for that. Maybe that should be re-thought for frameworks. I.e. keep the CPU% like now but add more columns for the individual cpu/wait times?
as that is a change which might break "My Workflow"(TM) (expect a script which parses the output) I doubt it's a 4.11 material, but should rather go into a feature release. Though that's just my personal opinion and I'm not a contributor to ksysguard.
