Hello,
FreeBSD IB folks.
I am working off of a FreeBSD 10.1 RC4 code base and I'm investigating
InfiniBand running on FreeBSD as part of a prototyping effort.
The prototype hardware is an Intel FDR InfiniBand* ConnectX-3* I/O Module AXX2FDRIBIOM
(Dual Port). According to the documentation , the Module is based on the
Mellanox MT27508A1-FCCR-FV Chip.
>From the Mellanox documentation the PCI Device IDs for the adapter are:
0x1003 MT27500 Family [ConnectX-3]
0x1004 MT27500 Family [ConnectX-3 Virtual Function]
>From looking at the FreeBSD driver source code it appears that the MT27500
family is not supported:
<snip>
#define PCI_DEVICE_ID_MELLANOX_TAVOR 0x5a44
#define PCI_DEVICE_ID_MELLANOX_ARBEL_COMPAT 0x6278
#define PCI_DEVICE_ID_MELLANOX_ARBEL 0x6282
#define PCI_DEVICE_ID_MELLANOX_SINAI_OLD 0x5e8c
#define PCI_DEVICE_ID_MELLANOX_SINAI 0x6274
<snip>
<snip>
/* Types of supported HCA */
enum {
TAVOR, /* MT23108 */
ARBEL_COMPAT, /* MT25208 in Tavor compat mode */
ARBEL_NATIVE, /* MT25208 with extended features */
SINAI /* MT25204 */
};
<snip>
Does anyone know if support is planned for the MT27500 (ConnectX-3)
Family of adapters.
Any info will be appreciated.
Thanks,
-Fred Lewis
