| Description: Interface is used to configure and connect device channels | |
| to component drivers. | |
| Attributes are visible only when configfs is mounted. To mount | |
| configfs in /sys/kernel/config directory use: | |

| The attributes: | |
| buffer_size | |
| configure the buffer size for this channel | |
| subbuffer_size | |
| configure the sub-buffer size for this channel | |
| (needed for synchronous and isochronous data) | |
| num_buffers | |
| configure number of buffers used for this | |
| channel | |
| datatype | |
| configure type of data that will travel over | |
| this channel | |
| direction | |
| configure whether this link will be an input | |
| or output | |
| dbr_size | |
| configure DBR data buffer size (this is used | |
| for MediaLB communication only) | |
| packets_per_xact | |
| configure the number of packets that will be | |
| collected from the network before being | |
| transmitted via USB (this is used for USB | |
| communication only) | |
| device | |
| name of the device the link is to be attached to | |
| channel | |
| name of the channel the link is to be attached to | |
| comp_params | |
| pass parameters needed by some components | |
| create_link | |
| write '1' to this attribute to trigger the | |
| creation of the link. In case of speculative | |
| configuration, the creation is post-poned until | |
| a physical device is being attached to the bus. | |
| destroy_link | |
| write '1' to this attribute to destroy an | |
| active link | |
