As Jeremy said it is ok. In pciconf output you can see
"class=0x010601". Your ICH9 controller has PCI subclass 0x06 (SATA)
and PCI programming interface 0x01 (AHCI).
Thank you both! I figured it was operating normally (I've noticed no
performance problems or oddities from the controller or devices
attached to it). I guess in trying to find out what was going on, I
saw this comment:
/* is this PCI device flagged as an AHCI compliant chip ? */
if (pci_read_config(dev, PCIR_PROGIF, 1) != PCIP_STORAGE_SATA_AHCI_1_0)
Which if I read the comment literally makes me believe if that does
not return non-zero/NULL, that my controller is not AHCI compliant.
But if it's falling back on a perfectly working generic AHCI
implementation, what it reports at boot time is moot. :)
