Mike Marciniszyn 18912c4524 IB/hfi1: Close VNIC sdma_progress sleep window ... The call to sdma_progress() is called outside the wait lock. In this case, there is a race condition where sdma_progress() can return false and the sdma_engine can idle. If that happens, there will be no more sdma interrupts to cause the wakeup and the vnic_sdma xmit will hang. Fix by moving the lock to enclose the sdma_progress() call. Also, delete the tx_retry. The need for this was removed by: commit bcad29137a ("IB/hfi1: Serve the most starved iowait entry first") Fixes: 64551ede6c ("IB/hfi1: VNIC SDMA support") Reviewed-by: Gary Leshner <Gary.S.Leshner@intel.com> Signed-off-by: Mike Marciniszyn <mike.marciniszyn@intel.com> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>		2018-12-06 20:15:36 -07:00
