Re: mpt(4) compatible with 53C1020?

The mpt(4) driver manpage says it supports the LSI Logic Fusion-MPT family of SCSI and Fibre Channel controllers, but it only explictly lists the 53c1030 SCSI controller. Does anyone know if it supports
the 53C1020/53C1020A, as used in the LSI20320-R and LSIU320
single-channel HBAs? Both are based on the Fusion-MPT architecture.

If it does not support it it shouldn't be hard to add: it may even just
be a matter of adding the right PCI ID to the driver's table.

Well, it's been over a year, but I finally got around to buying an LSI20320-R, and the mpt(4) driver supports it fine (no need to add the PCI ID).

However, NetBSD shows it as "LSI Logic 53c1030 Ultra320 SCSI", even though it has a 53C1020 on it. From what I gather, the 53C1030 dual-channel chip shows up on the PCI bus as two functions, both with PCI ID 1000/0030, whereas the 53C1020 single-channel chip shows up as a single function with ID 1000/0030. Perhaps pcidevs should call it "LSI Logic 53C1020/53C1030 Ultra320 SCSI" instead? FWIW, the Windows driver mentions both: "LSI Adapter, Ultra320 SCSI 2000 series, (w/1020/1030)(StorPort)". It's just a minor cosmetic thing in any case... What *would* be useful is to explicitly mention 53C1020 support in the mpt(4) manpage:
