I try to use an Atto Dual-Channel Low-Profile PCIExpress SCSI HBA (<http://www.attotech.com/ultra5Dlowpro.html>) with Linux (2.6.18.1, 2.6.19rc6). (Atto provides a Linux driver on CD, but I prefer to use drivers included in the vanilla Linux kernel. It looks like their driver does not include all source code; but I might be wrong on this.) According to lspci the card seems to include a vanilla Symbios Logic 1030 Chip (with an ATTO Vendor ID) and an Intel PCI-to-PCIExpress bridge: 09:00.0 PCI bridge: Intel Corporation 41210 [Lanai] Serial to Parallel PCI Bridge (A-Segment Bridge) (rev 09) 09:00.2 PCI bridge: Intel Corporation 41210 [Lanai] Serial to Parallel PCI Bridge (B-Segment Bridge) (rev 09) 0a:04.0 SCSI storage controller: Atto Technology Ultra320 SCSI Host Adapter (rev 08) 0a:04.1 SCSI storage controller: Atto Technology Ultra320 SCSI Host Adapter (rev 08) 09:00.0 0604: 8086:0340 (rev 09) 09:00.2 0604: 8086:0341 (rev 09) 0a:04.0 0100: 117c:0030 (rev 08) 0a:04.1 0100: 117c:0030 (rev 08) I added the new vendor ID to the fusion driver; with this kernel I can access a hard disk attached to that controller: diff -uprN linux-2.6.18.1-common/drivers/message/fusion/mptspi.c linux-2.6.18.1-atto/drivers/message/fusion/mptspi.c --- linux-2.6.18.1-common/drivers/message/fusion/mptspi.c 2006-11-15 14:08:39.000000000 +0100 +++ linux-2.6.18.1-atto/drivers/message/fusion/mptspi.c 2006-11-15 14:09:17.000000000 +0100 @@ -775,6 +775,8 @@ static struct pci_device_id mptspi_pci_t PCI_ANY_ID, PCI_ANY_ID }, { PCI_VENDOR_ID_LSI_LOGIC, MPI_MANUFACTPAGE_DEVID_53C1035, PCI_ANY_ID, PCI_ANY_ID }, + { PCI_VENDOR_ID_ATTO, MPI_MANUFACTPAGE_DEVID_53C1030, + PCI_ANY_ID, PCI_ANY_ID }, {0} /* Terminating entry */ }; MODULE_DEVICE_TABLE(pci, mptspi_pci_table); diff -uprN linux-2.6.18.1-common/include/linux/pci_ids.h linux-2.6.18.1-atto/include/linux/pci_ids.h --- linux-2.6.18.1-common/include/linux/pci_ids.h 2006-10-14 05:34:03.000000000 +0200 +++ linux-2.6.18.1-atto/include/linux/pci_ids.h 2006-11-15 14:11:26.000000000 +0100 @@ -1440,6 +1440,8 @@ #define PCI_DEVICE_ID_TOSHIBA_TC86C001_MISC 0x0108 #define PCI_DEVICE_ID_TOSHIBA_SPIDER_NET 0x01b3 +#define PCI_VENDOR_ID_ATTO 0x117c + #define PCI_VENDOR_ID_RICOH 0x1180 #define PCI_DEVICE_ID_RICOH_RL5C465 0x0465 #define PCI_DEVICE_ID_RICOH_RL5C466 0x0466 I tested this with Linux 2.6.19-rc6 too and it works.
