Hello, We've been seeing some nasty data corruption issues on some platforms. We've been capturing PCI-E traces looking for something nasty but we haven't found anything yet. One of the hardware guys if asking if there is a call in Linux to issue a PME_Turn_Off broadcast message.
PME_Turn_Off Broadcast Message Before main component power and reference clocks are turned off, the Root Complex or Switch Downstream Port must issue a broadcast Message that instructs all agents downstream of that point within the hierarchy to cease initiation of any subsequent PM_PME Messages, effective immediately upon receipt of the PME_Turn_Off Message.
This must be initiated from the root complex. Is there such a call in linux?
Thanks, mikem
