Does anybody know what is the minimum expected time for sleep period<br>>> with the cpuidle ?<br>By sleep period do you mean sleep time for complete device or only for cpu's? If you want to check for device as a whole, you can see the print in the kernel log. If you want to check programmatically, suspend_devices_and_enter() is the function.<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Oct 10, 2014 at 4:01 AM, <span dir="ltr"><<a href="mailto:Valdis.Kletnieks@vt.edu" target="_blank">Valdis.Kletnieks@vt.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On Thu, 09 Oct 2014 21:28:23 +0300, Ran Shalit said:<br>

<br>
</span>Both processor dependent and sleep level dependent. There's a certain<br>
amount of latency induced by the hardware waking up.<br>
<br>
Look at /sys/devices/system/cpu/cpu*/cpuidle/state*/latency<br>
