2013-04-24gianfar: Optimization for routed packets by exchanging rx/tx buffersRajan Gupta
Patch enhances the Gianfar driver performance for the packets that are received by the driver and transmitted by the driver in the same context. Performance is enhanced by exchanging the buffer between the Tx and Rx rings, rather than allocating buffer from kernel or taking it from recycle queue. Patch keeps the TX interupt masked by default and skb cleanup is done in the xmit function just before skb is recybled back to the RX ring. TX interupt is unmasked only when H/W transmit queue is full, in TX interupt handler stopped tx queues are started again when the H/W has cleaned the TX buffer rings. As TX interups are disabled by default, RFC1588 timestamping is not done and 1588 ptp protocol doesnot works with this optimization. Patch gives best performance with DEFAULT_RX_RING_SIZE 32, DEFAULT_TX_RING_SIZE 32, and GFAR_DEV_WEIGHT 32. Patch improves the forwarding performance of offload implementation like ASF by around 50% and linux forwarding performance by 20%.

Use TSTAT TXF h/w indication to identify the active Tx queues. Simplify the polling routine to make it faster. No need to poll the Tx rings in a loop due to Tx interrupt coalescing plus the fact that Tx polling does not consume NAPI budget, as Tx ring cleanup is run to completion. This contributes to a faster/ more responsive cleanup of Tx rings reducing the possibility of Tx congestion (Tx timeout triggering).

On certain chip like MPC8536 and P1022, system can be waked up from sleep by user-defined packet and Magic Patcket.(The eTSEC cannot supports both types of wake-up event simultaneously.) This patch implements wake-up on user-defined patcket including ARP request packet and unicast patcket to this station. When entering suspend state, the gianfar driver sets receive queue filer table to filter all of packets except ARP request packet and unicast patcket to this station. The driver temporarily uses the last receive queue to receive the user defined packet. In suspend state, the receive part of eTSEC keeps working. When receiving a user defined packet, it generates an interrupt to wake up the system. The rule of the filer table is as below. if (arp request to local ip address) accept it to the last queue elif (unicast packet to local mac address) accept it to the last queue else reject it endif Note: The local ip/mac address is the ethernet primary IP/MAC address of the station. Do not support multiple IP/MAC addresses. Here is an example of enabling and testing wake up on user defined packet. ifconfig eth0 10.193.20.169 ethtool -s eth0 wol a echo standby > /sys/power/state or echo mem > /sys/power/state Ping from PC host to wake up the station: ping 10.193.20.169 Change-Id: Ib3a29047bb55c770fe8cacae3299a5e5f3420c89 Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Jin Qing <b24347@freescale.com> Signed-off-by: Li Yang <leoli@freescale.com> Signed-off-by: Zhao Chenhui <chenhui.zhao@freescale.com> Acked-by: Andy Fleming <afleming@freescale.com> Reviewed-on: http://git.am.freescale.net:8181/1517 Reviewed-by: Manoil Claudiu-B08782 <claudiu.manoil@freescale.com> Reviewed-by: Fleming Andrew-AFLEMING <AFLEMING@freescale.com> Tested-by: Fleming Andrew-AFLEMING <AFLEMING@freescale.com>

2013-04-18dpaa_eth: Delay buffer pool seeding for private portsIoana Radulescu
Until now, all private ports had to be configured to use the same buffer size, as they all share a common buffer pool. Create the framework for working with different buffer sizes on the private ports; a single, common buffer pool is still used by all private ports. The pool is seeded with buffers large enough to accomodate frames for all private ports. In order to be able to compute the largest needed buffer size, the buffer pool seeding is delayed until the first private interface is raised. Temporarily disable the boot-time ethernet unit test, which requires the use of the common buffer pool.

2013-04-15gianfar: Optimize Tx/Rx ring cleanup with Tx/Rx NAPIClaudiu Manoil
Add a separate NAPI poll routine for Tx cleanup to be triggerred independently by the Tx confirmation interrupts only. Existing poll function is modified to handle only the Rx path processing. The Tx poll routine does not need a budget, since Tx processing doesn't consume NAPI budget, and hence it is registered with minimum NAPI weight. This way the Tx poll routine won't compete for budget with the Rx poll routine. The Rx poll routine is registered with the maximum NAPI weight, just as before. The gfar_configure_coalescing function is simply split in two so that the coalescing timers can be updated separately between the Rx and Tx paths. The schedule cleanup ISR part has been changed to handle the Rx and Tx interrupts independently (since we have separate interrupt lines for Rx and Tx). NAPI scheduling does not require locking since we have different NAPI instances between the Rx and Tx confirmation paths now. This generaly improves the driver's response, most notably when forwading multiple opposite flows.
