<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Currently, In Mtjade platform of Ampere, we have SMPro mdf drivers (SMPro hwmon, SMPro errmon, SMPro misc driver).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The drivers will be loaded by kernel when the BMC boot up. But they are only binded when the host is already On.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">They are also unbinded when the host is Off.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">To support binding/unbinding the SMPro drivesr, we have one service name driver-binder.<o:p></o:p></span></p>
<ol style="margin-top:0cm" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US">When the Dbus property CurrentHostState of service xyz.openbmc_project.State.Host changes to “not Off”, we will bind the drivers.<o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1"><span lang="EN-US">When the Dbus property RequestedHostTransition of service xyz.openbmc_project.State.Host OR Dbus property RequestedPowerTransition of xyz.openbmc_project.State.Chassis<o:p></o:p></span></li></ol>
<p class="MsoListParagraph"><span lang="EN-US">change to Off, we will unbind the drivers.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The driver-binder is working as expected, it have the configuration file to configure which drivers will be binded/unbinded.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">But that is our solution.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Do we have any common solution to do that job?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
