hermon - ConnectX MT25408/MT25418/MT25428 InfiniBand (IB) Driver


The hermon driver is an IB Architecture-compliant implementation of an
HCA, which operates on the Mellanox MT25408, MT25418 and MT25428
InfiniBand ASSPs using host memory for context storage rather than
locally attached memory on the card. Cards based on these ASSP's
utilize the PCI-Express I/O bus. These ASSP's support the link and
physical layers of the InfiniBand specification while the ASSP and the
driver support the transport layer.

The hermon driver interfaces with the InfiniBand Transport Framework
(IBTF) and provides an implementation of the Channel Interfaces that are
defined by that framework. It also enables management applications and
agents to access the IB fabric.

Writing Device Drivers


In addition to being logged, the following messages may appear on the
system console:

hermoni: driver attached for maintenance mode only.

There was a failure in the boot process of the hermon ASSP and
the only function that can be performed is to re-flash firmware on
the ASSP. (Note that i represents the instance of the hermon device

hermoni: driver failed to attach

The ASSP could not boot into either operational (HCA) mode or into
maintenance mode. The device is inoperable. (Note that i represents
the instance of the hermon device number.)

Unexpected port number in port state change event.

A port state change event occurred, but the port number in the
message does not exist on this HCA. This message also indicates the
port number that was in the port state changed.

Hermon driver successfully detached.

The driver has been removed from the system and the HCA is no longer
available for transfer operations.

hermoni: port m up.

A port up asynchronous event has occurred. (Note that i represents
the instance of the Hermon device number while "m" represents the
port number on the Hermon device.

hermoni: port m down.

A port up asynchronous event has occurred. Similar to port up event.

hermon: <command name> command failed.

A internal firmware command failed to execute.
