Hi Kevin, I have updated the script you shared here:
https://wiki.linaro.org/WorkingGroups/PowerManagement/Doc/AdaptiveTickless?action=AttachFile&do=view&target=nohz-test-cpuset.sh 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 :) -- viresh
is-cpu-isolated.sh
Description: Bourne shell script
