Context 0 (which handles the error packets) can potentially receive an invalid rhf. Hence, it can not depend on RHF sequence number and can only use DMA_RTAIL mechanism. Detect such packets with invalid rhf using rhf sequence counting mechanism and drop them. As DMA_RTAIL mechanism has performance penalties, do not use context 0 for performance critical verbs path. Use context 0 for VL15 (MAD), multicast and error packets. Reviewed-by:

The current send function handlers are passed a bunch of parameters that are already part of the data structure that is passed in first (qp). This patch removes all of this and just passes the QP. Reviewed-by:

Implement ACK coalesing logic using a 8 bit counter. The algorithm is send pio ack when: - fecn present - this is the first packet in an interrupt session - counter is >= HFI1_PSN_CREDIT Otherwise the ack is defered. Reviewed-by:

Mike Marciniszyn authored
This patch is a prelimary patch required to coalesce acks. The routine to "schedule" a QP for sending a NAK is now centralized in rc_defer_ack(). The flag is changed for clarity since the all acks will potentially use the deferral mechanism. Reviewed-by:

Disabling one receive context when RX_DMA is receiving a packet can cause incorrect packet delivery for a subsequent packet on another receive context. This is resolved by doing the following: 1. Programming dummy tail address for every receive context before enabling it 2. While deallocating receive context resetting tail address to dummy address 3. Leaving the dummy address in when disabling tail update 4. When disabling receive context leaving tail update enabled Reviewed-by:

Now that we have a multi-threaded work queue we precomputed and store the SC and SDE on RC and UC QPs for faster access. Reviewed-by:
-
Mike Marciniszyn authored
The workqueue is currently single threaded per port which for a small number of SDMA engines is ok. For hfi1, the there are up to 16 SDMA engines that can be fed descriptors in parallel. Use alloc_workqueue with a workqueue limit of the number of sdma engines and with WQ_CPU_INTENSIVE and WQ_HIGHPRI specified. Then change send to use the new scheduler which no longer needs to get the s_lock Reviewed-by:

During driver load the thermal sensor needs to be reset prior to initialization of the sensor. This prevents a possible sensor lock up which can cause the wrong temperature value to be reported. This fix leads to remove disabling thermal polling from reset_asic_csrs() function.
