* RDMA/cxgb3: Doorbell overflow avoidance and recoverySteve Wise2010-02-241-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | T3 hardware doorbell FIFO overflows can cause application stalls due to lost doorbell ring events. This has been seen when running large NP IMB alltoall MPI jobs. The T3 hardware supports an xon/xoff-type flow control mechanism to help avoid overflowing the HW doorbell FIFO. This patch uses these interrupts to disable RDMA QP doorbell rings when we near an overflow condition, and then turn them back on (and ring all the active QP doorbells) when when the doorbell FIFO empties out. In addition if an doorbell ring is dropped by the hardware, the code will now recover. Design: cxgb3: - enable these DB interrupts - in the interrupt handler, schedule work tasks to call the ULPs event handlers with the new events. - ring all the qset txqs when an overflow is detected. iw_cxgb3: - disable db ringing on all active qps when we get the DB_FULL event - enable db ringing on all active qps and ring all active dbs when we get the DB_EMPTY event - On DB_DROP event: - disable db rings in the event handler - delay-schedule a work task which rings and enables the dbs on all active qps. - in post_send and post_recv logic, don't ring the db if it's disabled.

* RDMA/cxgb3: Handle port events properlySteve Wise2009-09-061-3/+5
| | | | | | | | | Massage the err_handler upcall into an event handler upcall, pass netdev port events to the cxgb3 ULPs and generate RDMA port events based on LLD port events. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* cxgb3: remove __GFP_NOFAIL usageDivy Le Ray2009-06-111-0/+3
| | | | | | | | | | | | | | | Pre-allocate a skb at init time to be used for control messages to the HW if skb allocation fails. Tolerate failures to send messages initializing some memories at the cost of parity error detection for these memories. Retry sending connection id release messages if both alloc_skb(GFP_ATOMIC) and alloc_skb(GFP_KERNEL) fail. Do not bring the interface up if messages binding queue set to port fail to be sent.

* cxgb3 - Fix dev->priv usageDivy Le Ray2007-08-311-0/+2
| | | | | | | | | | | | cxgb3 used netdev_priv() and dev->priv for different purposes. In 2.6.23, netdev_priv() == dev->priv, cxgb3 needs a fix. This patch is a partial backport of Dave Miller's changes in the net-2.6.24 git branch. Without this fix, cxgb3 crashes on 2.6.23.
