| * Texas Instruments CPSW ethernet driver |
| |
| Multiqueue & CBS & MQPRIO |
| ===================================================================== |
| ===================================================================== |
| |
| The cpsw has 3 CBS shapers for each external ports. This document |
| describes MQPRIO and CBS Qdisc offload configuration for cpsw driver |
| based on examples. It potentially can be used in audio video bridging |
| (AVB) and time sensitive networking (TSN). |
| |
| The following examples were tested on AM572x EVM and BBB boards. |
| |
| Test setup |
| ========== |
| |
| Under consideration two examples with AM572x EVM running cpsw driver |
| in dual_emac mode. |
| |
| Several prerequisites: |
| - TX queues must be rated starting from txq0 that has highest priority |
| - Traffic classes are used starting from 0, that has highest priority |
| - CBS shapers should be used with rated queues |
| - The bandwidth for CBS shapers has to be set a little bit more then |
| potential incoming rate, thus, rate of all incoming tx queues has |
| to be a little less |
| - Real rates can differ, due to discreetness |
| - Map skb-priority to txq is not enough, also skb-priority to l2 prio |
| map has to be created with ip or vconfig tool |
| - Any l2/socket prio (0 - 7) for classes can be used, but for |
| simplicity default values are used: 3 and 2 |
| - only 2 classes tested: A and B, but checked and can work with more, |
| maximum allowed 4, but only for 3 rate can be set. |
