Hi all, According to PCI 3.0 spec, ACHI's PCI class code is 0x010601, and I suggest the ahci driver had better try to claim all ahci controllers, pls see the following patch: diff -Nur linux-2.6.17/drivers/scsi/ahci.c linux-2.6.17-ahci/drivers/scsi/ahci.c --- linux-2.6.17/drivers/scsi/ahci.c 2006-06-18 09:49:35.000000000 +0800 +++ linux-2.6.17-ahci/drivers/scsi/ahci.c 2006-10-31 22:50:54.000000000 +0800 @@ -296,6 +296,11 @@ board_ahci }, /* ATI SB600 non-raid */ { PCI_VENDOR_ID_ATI, 0x4381, PCI_ANY_ID, PCI_ANY_ID, 0, 0, board_ahci }, /* ATI SB600 raid */+ /* Claim all AHCI controllers not listed above. + * According to PCI 3.0, AHCI's class code is 0x010601 + */+ { PCI_AND_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, 0x010601,0xffffff, + board_ahci },{ } /* terminate list */ };
Since things have settled in this area, yes, this would probably be a good thing to add.
For the benefit of others, some background: we should not be -removing- any PCI IDs due to this, because quite often the PCI class code will be RAID or something else, yet still be drive-able with this ahci driver.
