Adaptec 1405 and mvsas

["Marco Gruß" <kork.test@gmail.com>]

Hello,

I recently acquired an Adaptec 1405 SAS/SATA HBA.

While there is a closed-source driver by Adaptec, called adpinv, I'd of
course like to get it to work with open drivers.

A lspci -v reveals that the controller is actually using a Marvell chip:

02:00.0 Serial Attached SCSI controller: Adaptec Device 0450 (rev 02)
         Subsystem: Marvell Technology Group Ltd. Device 6440

02:00.0 0107: 9005:0450 (rev 02)
         Subsystem: 11ab:6440

(The output of lspci -vv is attached below)

So I simply added an entry for this PCI id to mvsas.c:

static struct pci_device_id __devinitdata mvs_pci_table[] = {
         { PCI_VDEVICE(MARVELL, 0x6320), chip_6320 },
         { PCI_VDEVICE(MARVELL, 0x6340), chip_6440 },
         {
                 .vendor         = PCI_VENDOR_ID_MARVELL,
                 .device         = 0x6440,
                 .subvendor      = PCI_ANY_ID,
                 .subdevice      = 0x6480,
                 .class          = 0,
                 .class_mask     = 0,
                 .driver_data    = chip_6480,
         },
         { PCI_VDEVICE(MARVELL, 0x6440), chip_6440 },
         { PCI_VDEVICE(MARVELL, 0x6480), chip_6480 },
+        { PCI_VDEVICE(ADAPTEC2, 0x0450), chip_6440 },

         { }     /* terminate list */
};

...with limited success:

I can actually use both devices (a (slow) OCZ SSD, and a dvd recorder),
but even during initialization, and afterwards, I get tons and tons of
these:

Aug 29 17:45:17 athlon kernel: mvsas 0000:02:00.0: RXQ_ERR 20000

Also, I don't like the "sas_ata_phy_reset: Unable to reset I T nexus?"
entries...

BTW: The driver loads fine on 2.6.30.5 x86_64, but oopses on
2.6.27.5 x86_64 (it still "works" anyway).

Unfortunately, my knowledge of Linux driver debugging ends here...
If there's anything I can do to help make this card work flawlessly,
I'd be glad to try it.

Thanks!
Marco
