.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is provided for management of the Connect-X4, 5 and 6 network adapters
|
|
in the aspects not covered by the generic
|
|
.Xr ifconfig 8
|
|
command, mostly related to the PCIe attachment and internal card working.
|
|
The utility executes commands on specific adapter, which is addressed using
|
|
.Em device:bus:slot:function
|
|
conventions of the PCIe buses.
|
|
You can match adapters ethernet name and addresses using the
|
|
.X pciconf 8
|
|
utility.
|
|
The address is passed as an argument of the
|
|
.Fl d
|
|
option, which must be specified for each invocation.
|
|
.Pp
|
|
When the driver detects the malfunctioning of the hardware, or by user
|
|
request, it is possible to create
|
|
.Em firmware dump ,
|
|
which contains debugging information about internal device state, for
|
|
analysis of the failure by the Mellanox support team.
|
|
.Pp
|
|
The following commands are currently implemented:
|
|
.Bl -tag -width indent
|
|
.It Fl E
|
|
Print EEPROM information
|
|
.It Fl e
|
|
Take the snapshot of the firmware registers state and store it in the
|
|
kernel buffer.
|
|
The buffer must be empty, in other words, no dumps should be written so
|
|
far, or existing dump cleared with the
|
|
.It Fl f
|
|
Flashes the firmware image
|
|
.Fa file.mfa2
|
|
to the specified adapter.
|
|
Image must be in MFA2 pack format and contain a component suitable
|
|
for the adapter hardware.
|
|
.Pp
|
|
Typically, PCIe link-level reset is required to activate the
|
|
newly flashed image, which can be performed by the system reboot
|
|
or using the
|
|
.Fl z
|
|
option.
|
|
.Fl r
|
|
command for the specified device.
|
|
.It Fl r
|
|
Clear the stored firmware dump, preparing the kernel buffer for
|
|
the next dump.
|
|
.It Fl w
|
|
Fetches the stored firmware dump and writes it into the file specified
|
|
by the
|
|
.Fl o
|
|
option argument.
|
|
.It Fl z
|
|
Performs PCIe link-level reset on the specified device.
|
|
.El
|
|
.Sh FILES
|
|
The
|
|
.Pa /dev/mlx5ctl
|
|
.Xr devfs 5
|
|
node is used to pass commands to the driver.
