Using fw_sbus_load to control SBus firmware load doesn't scale across multiple HFI1 cards in a single system. This patch ensures that the SBus firmware is loaded once per ASIC. Reviewed-by:

When under heavy load, the receive interrupt handler can run too long with IRQs disabled. Add a mixed-mode threading scheme. Initially process packets in the handler for quick responses (latency). If there are too many packets to process move to a thread to continue (bandwidth). Reviewed-by:

In preparation for threading the receive interrupt, add irqsaves in the packet processing path. When the receive interrupt is threaded, the packet processing path is no longer guaranteed to have IRQs disabled. Add irqsaves where needed on several locks in the packet processing path. Anything that did not have an obvious, "close" irqsave in its caller is a candidate. Reviewed-by:

The SDMA engines were configured to generate progress interrupts every time they processed N/2 descriptors (where N is the size of the descriptor queue). This interval was too infrequent, leading to degraded performance. This commit adds a module parameter, as well as a recommended default, which allows for the tuning of the interrupt frequency.

The address being mapped into a process's memory for notification events was improperly calculated due to cast that was happening too early. dd->events is a pointer and should have been casted to unsigned long after the pointer arithmetic was done, not before. As a result, processes were looking at the wrong place and not seeing their notification events. Signed-off-by:

User SDMA keeps track of progress into the submitted IO vectors by tracking an offset into the vectors when packets are submitted. This offset is updated after a successful submission of a txreq to the SDMA engine. The same offset was used when determining whether an IO vector should be 'freed' (pages unpinned) in the SDMA callback functions. This was causing a silent data corruption in big jobs (> 2 nodes, 120 ranks each) on the receive side because the send side was mistakenly unpinning the vector pages before the HW has processed all descriptors referencing the vector.

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:

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:

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 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:
