* IB/qib: Fix a possible data corruption when receiving packetsRam Vepa2012-01-121-1/+3
| | | | | | | | | | | | | | 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: Fix interrupt mitigationMike Marciniszyn2011-01-101-1/+1
| | | | | | | | | | | 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: Clear 6120 hardware error registerRalph Campbell2010-07-061-2/+1
| | | | | | | | | The hardware error register needs to be cleared or another interrupt will be generated, thus causing an infinite loop. This is a regression introduced when removing debug output.
