CABLE_IS_40WIRE(9) libata Core Internals CABLE_IS_40WIRE(9) NAME cable_is_40wire - 40/80/SATA decider SYNOPSIS int cable_is_40wire(struct ata_port * ap); ARGUMENTS ap port to consider DESCRIPTION This function encapsulates the policy for speed management in one place. At the moment we donĀ“t cache the result but there is a good case for setting ap->cbl to the result when we are called with unknown cables (and figuring out if it impacts hotplug at all). Return 1 if the cable appears to be 40 wire. AUTHOR Jeff Garzik Author. COPYRIGHT Kernel Hackers Manual 2.6. November 2013 CABLE_IS_40WIRE(9)[top]
