Hi Kevin,

I have updated the script you shared here:

https://wiki.linaro.org/WorkingGroups/PowerManagement/Doc/AdaptiveTickless?a...

to get the time for which cpu wasn't getting interrupted.

Probably this might be useful for few other folks as well and so sharing it.. I am bad at scripting, so please ignore silly code in there :)

So, the script will take a parameter, i.e. number of samples you need and will output the amount of time CPU1 (of a dual-core machine) was isolated.

There is a variable "isdebug", which can be used to enable/disable debug messages.

Let me know if there is something really stupid in it :)

Just for records, this script is pushed here (for others to us):
