<p class="MsoNormal">It is same for all platforms. Do you see swampd running in your platform. If it is running then you can change your temperature value beyong any of limit provided in fan table and fan speed should change to the mention values in table.<o:p></o:p></p>

<p class="MsoNormal">Hi Vijay,<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Thanks for your response.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">We are using entity-manager for fan speed controller. So we have entry for fan speed controller in json file.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">As you suggested, we could able to see some pwm and fan speed values are changing if we update the temperature values while swampd is running in TP.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">In YV2, the pwm values are not updating properly if temperature updates.
<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Please find the attached documents for temperatures and pwm values of TP and YV2.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">As of now, we are using same TP speed controller table entries for YV2.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Could you please let us know the procedure for fan speed validation.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>

<p class="MsoNormal">If you are using entity manager, then you should have entry for fan speed controller table in entity manager json file. Then you need to run swampd. Once swampd is running then you can change temperature values via dbus interface and see
if fan speeds are changing.<o:p></o:p></p>
