vdpa-dev - vdpa device configuration
vdpa dev [ OPTIONS ] { COMMAND| help } OPTIONS := { -V[ersion] } vdpa dev show [ DEV ] vdpa dev help vdpa dev add name NAME mgmtdev MGMTDEV [ device_features DEVICE_FEATURES ] [ mac MACADDR ] [ mtu MTU ] [ max_vqp MAX_VQ_PAIRS ] vdpa dev del DEV vdpa dev config show [ DEV ] vdpa dev vstats show DEV qidx QUEUE_INDEX
vdpa dev show - display vdpa device attributes DEV - specifies the vdpa device to show. If this argument is omitted all devices are listed. Format is: VDPA_DEVICE_NAME vdpa dev add - add a new vdpa device. name NAME Name of the new vdpa device to add. mgmtdev MGMTDEV Name of the management device to use for device addition. device_features DEVICE_FEATURES Specifies the virtio device features bit-mask that is provisioned for the new vdpa device. The bits can be found under include/uapi/linux/virtio*h. see macros such as VIRTIO_F_ and VIRTIO_XXX(e.g NET)_F_ for specific bit values. This is optional. mac MACADDR - specifies the mac address for the new vdpa device. This is applicable only for the network type of vdpa device. This is optional. mtu MTU - specifies the mtu for the new vdpa device. This is applicable only for the network type of vdpa device. This is optional. vdpa dev del - Delete the vdpa device. DEV - specifies the vdpa device to delete. vdpa dev config show - Show configuration of specific device or all devices. DEV - specifies the vdpa device to show its configuration. If this argument is omitted all devices configuration is listed. Format is: VDPA_DEVICE_NAME vdpa dev vstats show - shows vendor specific statistics for the given device and virtqueue index. The information is presented as name- value pairs where name is the name of the field and value is a numeric value for it. DEV - specifies the vdpa device to query qidx QUEUE_INDEX - specifies the virtqueue index to query
vdpa dev show Shows the all vdpa devices on the system. vdpa dev show foo Shows the specified vdpa device. vdpa dev add name foo mgmtdev vdpa_sim_net Add the vdpa device named foo on the management device vdpa_sim_net. vdpa dev add name foo mgmtdev vdpa_sim_net device_features 0x300020000 Add the vdpa device named foo on the management device vdpa_sim_net with device_features of 0x300020000 vdpa dev add name foo mgmtdev vdpa_sim_net mac 00:11:22:33:44:55 Add the vdpa device named foo on the management device vdpa_sim_net with mac address of 00:11:22:33:44:55. vdpa dev add name foo mgmtdev vdpa_sim_net mac 00:11:22:33:44:55 mtu 9000 Add the vdpa device named foo on the management device vdpa_sim_net with mac address of 00:11:22:33:44:55 and mtu of 9000 bytes. vdpa dev add name foo mgmtdev auxiliary/mlx5_core.sf.1 mac 00:11:22:33:44:55 max_vqp 8 Add the vdpa device named foo on the management device auxiliary/mlx5_core.sf.1 with mac address of 00:11:22:33:44:55 and max 8 virtqueue pairs vdpa dev del foo Delete the vdpa device named foo which was previously created. vdpa dev config show foo Shows the vdpa device configuration of device named foo. vdpa dev vstats show vdpa0 qidx 1 Shows vendor specific statistics information for vdpa device vdpa0 and virtqueue index 1
