Overview

Get queue information from the kernel. Only configured queues will be reported (as opposed to all available hardware queues).

Instance Method Details

#dmabuf ⇒ Integer

ID of the dmabuf attached to this queue, if any.

Returns:

  • (Integer)

See Also:



2118
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2118

def dmabuf; attributes[:"dmabuf"]&.value; end

#id ⇒ Integer

Queue index; most queue types are indexed like a C array, with indexes starting at 0 and ending at queue count - 1. Queue indexes are scoped to an interface and queue type.

Returns:

  • (Integer)

See Also:

# File 'nl-linux/generated/nl/linux/netdev.rb', line 2096

def id; attributes[:"id"]&.value; end

#ifindex ⇒ Integer

ifindex of the netdevice to which the queue belongs.

Returns:

  • (Integer)

See Also:



2101
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2101

def ifindex; attributes[:"ifindex"]&.value; end

#io_uring ⇒ AttributeSets::IoUringProviderInfo

io_uring memory provider information.

Returns:

See Also:



2123
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2123

def io_uring; attributes[:"io_uring"]&.value; end

#lease ⇒ AttributeSets::Lease

A queue from a virtual device can have a lease which refers to another queue from a physical device. This is useful for memory providers and AF_XDP operations which take an ifindex and queue id to allow applications to bind against virtual devices in containers.

Returns:

See Also:



2136
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2136

def lease; attributes[:"lease"]&.value; end

#napi_id ⇒ Integer

ID of the NAPI instance which services this queue.

Returns:

  • (Integer)

See Also:



2113
 
# File 'nl-linux/generated/nl/linux/netdev.rb', line 2113

def napi_id; attributes[:"napi_id"]&.value; end

#type ⇒ Integer

Queue type as rx, tx. Each queue type defines a separate ID space. XDP TX queues allocated in the kernel are not linked to NAPIs and thus not listed. AF_XDP queues will have more information set in the xsk attribute.

Known enum values are defined in Enums::QueueType.

Returns:

  • (Integer)

# File 'nl-linux/generated/nl/linux/netdev.rb', line 2108

def type; attributes[:"type"]&.value; end

#xsk ⇒ AttributeSets::XskInfo

XSK information for this queue, if any.

Returns:

# File 'nl-linux/generated/nl/linux/netdev.rb', line 2128

def xsk; attributes[:"xsk"]&.value; end
