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 don´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.
