* IB/qib: Fix a possible data corruption when receiving packetsRam Vepa2012-01-121-2/+4
| | | | | | | | | | | | | | commit eddfb675256f49d14e8c5763098afe3eb2c93701 upstream. Prevent a receive data corruption by ensuring that the write to update the rcvhdrheadn register to generate an interrupt is at the very end of the receive processing.

* IB/qib: Ensure that LOS and DFE are being turned offMitko Haralanov2011-06-171-7/+18
| | | | | | | | | | | | Due to timing, it is possible for the LOS and DFE to remain on. This is due to the link progressing to LinkUP prior to the driver getting the first Status Changed interrupt. By expanding the conditions under which LOS is turned off and DFE timeout is being set, timing is no longer an issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * ib_wq is added, which is used as the common workqueue for infiniband instead of the system workqueue. All system workqueue usages including flush_scheduled_work() callers are converted to use and flush ib_wq. * cancel_delayed_work() + flush_scheduled_work() converted to cancel_delayed_work_sync(). * qib_wq is removed and ib_wq is used instead.

* | IB/qib: Change receive queue/QPN selectionMike Marciniszyn2011-01-101-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | The basic idea is that on SusieQ, the difficult part of mapping QPN to context is handled by the mapping registers so the generic QPN allocation doesn't need to worry about chip specifics. For Monty and Linda, there is no mapping table so the qpt->mask (same as dd->qpn_mask), is used to see if the QPN to context falls within [zero..dd->n_krcv_queues).

* | IB/qib: Fix interrupt mitigationMike Marciniszyn2011-01-101-3/+7
| | | | | | | | | | | | | | | | | | | | | | For SusieQ we need to write to the interrupt timer register before updating the header queue head with interrupt count. This is to ensure that the timer is enabled properly and a receive available interrupt is delivered. Otherwise this interrupt can be lost if the receiver header/eager queues are full before the timer is enabled.

* IB/qib: Set cfgctxts to number of CPUs by defaultRalph Campbell2010-08-031-1/+1
| | | | | | | | | | | | Up to now, we have set the number of available user contexts based on the number of hardware contexts which is set according to the number of available CPUs. This was fine since most CPUs had a power of two number of cores and the chip supported 4, 8, or 16 user contexts. Now that some systems have 12 cores, the default isn't optimal and should be set to 12 even though 16 hardware contexts need to be enabled.

* IB/qib: Use a single txselect module parameter for serdes tuningRalph Campbell2010-05-261-403/+179
| | | | | | | | | | | | As part of the earlier patches submitted and reviewed, it was agreed to change the way serdes tuning parameters were specified to the driver. The updated patch got dropped by the linux-rdma email list so the earlier version of qib_iba7322.c ended up being used. This patch updates qib_iab7322.c to the simpler, single parameter method of setting the serdes parameters.
