The DC firmware overwrites the enable_lane_tx register and does not update it on a host request to go to Poll. This causes an infinite loop through the LNI state machine if a link width downgrade occurs. This patch re-sets the enable_lane_tx register to all 4 lanes. Reviewed-by:

Reset firmware instead of reloading Sbus firmware if it's already done for this ASIC. To work around thermal polling problem in firmware, don't reload Sbus firmware, instead, reset the firmware on the initialization of the second HFI. Reviewed-by:

This fixes transmit errors when the number of scatter gather elements in the request is more that the number of per packet descriptors supported by the hardware, allocate and coalesce the extra scatter gather elements into a single buffer. The last descriptor is reserved and used for this coalesced buffer. Verbs potentially need this support when transferring small data chunks involving different memory regions. Reviewed-by:

The QSFP interface code has been running without issues and the flag is never set to off. This patch removes the QSFP_ENABLED bit from HFI1_CAP. Reviewed-by:

If packets stop egressing the hardware link, software can lock up. Implement a timeout for send context halt recovery. This patch increases the timeout for packet egress to 500 us and timer resets to zero if the packet occupancy changes. Also we bounce the link on time out. Reviewed-by:

The latest version of the 8051 firmware will wait longer when bringing the link down. Extend the driver's timeout to go with that. Reviewed-by:

The ASIC registers were not reset on FLR, and the code to protect the ASIC block against multiple initializations by peer HFIs did not extend to multiple ASICs in a system. This patch addresses this gap. Reviewed-by:

The clear_ahg call is new in hfi1 vs qib. For small messages the progress routine always builds one and clears out the ahg state when the queue has gone to empty which is the predominant case for small messages. Inline the routine and avoid the call to sdma_ahg_free to mitigate the performance impact. Finally, move the routine to qp.h for scope reasons. Reviewed-by:
