FIrst draft of text for Tuning Guide tuned-profiles-realtime section none

Description Clark Williams 2015-08-03 13:53:34 UTC 
Description of problem:

The 'tuned' package has added a 'tuned-profiles-realtime' sub-package which is used to do cpu-isolation and irq tuning. When the profile is activated it reads a variable section, which specifies the cpus to be isolated and moves all threads that may be moved off those cpu cores.

We need to add a section to the Realtime Tuning Guide which explains what the profile does and the parameters that are available for user modification.

Hi Clark, I'm going to work on this BZ but I don't have access to that etherpad. Please give me access.

Hi Maxim,
Please use the attached file 
	FIrst draft of text for Tuning Guide tuned-profiles-realtime section 

We did not want to loose the text, so we attached the contents of the etherpad to this bugzilla. Makes it easier for everyone. Please let us know if you have any questions.
