DESCRIPTION
devlink port set - change devlink port attributes
DEV/PORT_INDEX - specifies the devlink port to operate on.
Format is:
BUS_NAME/BUS_ADDRESS/PORT_INDEX
type { eth | ib | auto }
set port type
eth - Ethernet
ib - Infiniband
auto - autoselect
devlink port split - split devlink port into more
DEV/PORT_INDEX - specifies the devlink port to operate on.
count COUNT
number of ports to split to.
devlink port unsplit - unsplit previously split devlink port
Could be performed on any split port of the same split group.
DEV/PORT_INDEX - specifies the devlink port to operate on.
devlink port show - display devlink port attributes
DEV/PORT_INDEX - specifies the devlink port to show. If this argument
is omitted all ports are listed.
devlink port health - devlink health reporting and recovery
Is an alias for devlink-health(8).
devlink port add - add a devlink port
DEV - specifies the devlink device to operate on. or
DEV/PORT_INDEX - specifies the devlink port index to use for the
requested new port. This is optional. When omitted, driver allocates
unique port index.
flavour { pcipf | pcisf }
set port flavour
pcipf - PCI PF port
pcisf - PCI SF port
pfnum PFNUMBER
Specifies PCI pfnumber to use on which a SF device to create
sfnum SFNUMBER
Specifies sfnumber to assign to the device of the SF. This
field is optional for those devices which supports auto assign-
ment of the SF number.
controller CNUM
Specifies controller number for which the SF port is created.
This field is optional. It is used only when SF port is created
for the external controller.
devlink port function set - Set the port function attribute(s).
DEV/PORT_INDEX - specifies the devlink port to operate on.
hw_addr ADDR
Hardware address of the function to set. This is a Ethernet MAC
address when port type is Ethernet.
state { active | inactive }
New state of the function to change to.
active - Once configuration of the function is done, activate
the function.
inactive - To inactivate the function and its device(s), set to
inactive.
roce { enable | disable }
Set the RoCE capability of the function.
migratable { enable | disable }
Set the migratable capability of the function.
devlink port del - delete a devlink port
DEV/PORT_INDEX - specifies the devlink port to delete.
devlink port param set - set new value to devlink port configuration param-
eter
DEV/PORT_INDEX - specifies the devlink port to operate on.
name PARAMETER
Specify parameter name to set.
value VALUE
New value to set.
cmode { runtime | driverinit | permanent }
Configuration mode in which the new value is set.
runtime - Set new value while driver is running. This configura-
tion mode doesn't require any reset to apply the new value.
driverinit - Set new value which will be applied during driver
initialization. This configuration mode requires restart driver
by devlink reload command to apply the new value.
permanent - New value is written to device's non-volatile mem-
ory. This configuration mode requires hard reset to apply the
new value.
devlink port param show - display devlink port supported configuration
parameters attributes
DEV/PORT_INDEX - specifies the devlink port to operate on.
name PARAMETER Specify parameter name to show. If this argument, as
well as port index, are omitted - all parameters supported by devlink
device ports are listed.
devlink port function rate - manage devlink rate objects
Is an alias for devlink-rate(8).
EXAMPLES
devlink port show
Shows the state of all devlink ports on the system.
devlink port show pci/0000:01:00.0/1
Shows the state of specified devlink port.
devlink port set pci/0000:01:00.0/1 type eth
Set type of specified devlink port to Ethernet.
devlink port split pci/0000:01:00.0/1 count 4
Split the specified devlink port into four ports.
devlink port unsplit pci/0000:01:00.0/1
Unplit the specified previously split devlink port.
devlink port health show
Shows status and configuration of all supported reporters regis-
tered on all devlink ports.
devlink port health show pci/0000:01:00.0/1 reporter tx
Shows status and configuration of tx reporter registered on
pci/0000:01:00.0/1 devlink port.
devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
Add a devlink port of flavour PCI SF on PCI PF having number 0 with
SF number 88. To make use of the function an example sequence is
to add a port, configure the function attribute and activate the
function. Once function usage is completed, inactivate the function
and finally delete the port. When there is desire to reuse the port
without deletion, it can be reconfigured and activated again when
function is in inactive state and function's operational state is
detached.
devlink port del pci/0000:06:00.0/1
Delete previously created devlink port. It is recommended to first
deactivate the function if the function supports state management.
devlink port function set pci/0000:01:00.0/1 hw_addr 00:00:00:11:22:33
Configure hardware address of the PCI function represented by
devlink port. If the port supports change in function state, hard-
ware address must be configured before activating the function.
devlink port function set pci/0000:01:00.0/1 state active
Activate the function. This will initiate the function enumeration
and driver loading.
devlink port function set pci/0000:01:00.0/1 state inactive
Deactivate the function. This will initiate the function teardown
which results in driver unload and device removal.
devlink port function set pci/0000:01:00.0/1 roce enable
This will enable the RoCE functionality of the function.
devlink port function set pci/0000:01:00.0/1 migratable enable
This will enable the migratable functionality of the function.
devlink port function set pci/0000:01:00.0/1 hw_addr 00:00:00:11:22:33
state active
Configure hardware address and also active the function. When a
function is activated together with other configuration in a single
command, all the configuration is applied first before changing the
state to active.
devlink dev param show
Shows (dumps) all the port parameters across all the devices regis-
tered in the devlink.
devlink dev param set pci/0000:01:00.0/1 name internal_error_reset
value true cmode runtime
Sets the parameter internal_error_reset of specified devlink port
(#1) to true.
devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88 con-
troller 1
Add a devlink port of flavour PCI SF on controller 1 which has PCI
PF of number 0 with SF number 88. To make use of the function an
example sequence is to add a port, configure the function attribute
and activate the function. Once the function usage is completed,
deactivate the function and finally delete the port. When there is
desire to reuse the port without deletion, it can be reconfigured
and activated again when function is in inactive state and func-
tion's operational state is detached.
