When CONFIG_DCB is disabled, we get a link error: drivers/infiniband/built-in.o: In function `bnxt_re_setup_qos': trace.c:(.text+0x155774): undefined reference to `dcb_ieee_getapp_mask' trace.c:(.text+0x155774): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask' trace.c:(.text+0x155794): undefined reference to `dcb_ieee_getapp_mask' trace.c:(.text+0x155794): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dcb_ieee_getapp_mask' Like the other drivers that use this function, a Kconfig dependency is the correct fix.

gcc-7 produces a mysterious warning about the size argument being potentially out of range: drivers/infiniband/hw/hfi1/verbs.c: In function 'init_cntr_names': drivers/infiniband/hw/hfi1/verbs.c:1644:2: error: 'memcpy': specified size between 18446744071562067968 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=] This seems to refer to a the case where an 64-bit size_t gets truncated into a negative 'int' and subsequently turned into a high 64-bit number again. The fix is clearly to use size_t here, which matches the type that gets used for this value elsewhere. Fixes: b7481944 ("IB/hfi1: Show statistics counters under IB stats interface") Signed-off-by:

The send complete for RC QPs mismanages the ack count when the responder side is only in RTR. A QP in that state cannot send requests, but it can be the target for operations that elicit responses. Adjust the RC completion logic to correct the count maintenance by reflecting RECV_OK in a new state test. Reviewed-by:

The EFI variable that provides board ID is named by the PCI address of the device, which is published in upper-case, while the HFI1 driver reads the EFI variable in lower-case. This prevents returning the correct board id when queried through sysfs. Read EFI variables in upper-case if the lower-case read fails. Reviewed-by:

Having per-CPU reference count for each MR prevents cache-line bouncing across the system. Thus, it prevents bottlenecks. Use per-CPU reference counts per MR. The per-CPU reference count for FMRs is used in atomic mode to allow accurate testing of the busy state. Other MR types run in per-CPU mode MR until they're freed. Reviewed-by:

Sebastian Sanchez authored
Receive code paths use the QP's device and port number to access the struct hfi1_ibport. When an instance of struct hfi1_ctxtdata is present, it can be used to access struct hfi1_ibport through a pointer. This makes struct hfi1_ibport lookup time faster as an array doesn't have to be indexed and access fields in other cache-lines. Reviewed-by:

The resource specific wait locking missed correcting the lock for the notify_error_qp() calldown. The code is fixed to correctly use the iowait lock field to protect the head that is protected by that lock. Fixes: Commit 4e045572 ("IB/hfi1: Add unique txwait_lock for txreq events") Reviewed-by:

After extended testing, it was found that the previous PCIe Gen 3 recipe, which used adaptive CTLE with Preset 4, could cause an NMI/Surprise Link Down in about 1 in 100 to 1 in 1000 power cycles on some platforms. New EV data combined with extensive empirical data indicates that the new recipe should use static CTLE with Preset 6 for all integrated silicon SKUs.

In the event that the IRQ thread is extremely busy, the processing of an rcd wait list can be delayed by quite a bit until the IRQ thread completes its work. The QP reset reference count wait can then appear to be stuck, thus causing up a QP destroy to emit the hung task diagnostic. Fix by processing the qp wait list periodically from the thread. The interval is a multiple (currently 4) of the MAX_PKT_RECV. Also, reduce some of the excessive inlining. The guidelines are per packet is ok inline, otherwise the choice is based on likelyhood of execution. Reviewed-by:

The destination address in a listening rdma_id does not have an address family. Since address family in both sides of a connection must be the same in rdma_bind_addr() we set the address family of the destination to the address family of the source. This patch serves the logic in cma_port_is_unique() which requires to know if destination address that is associated with a rdma_id is any address (cma_zero_addr() and cma_loopback_addr()). This can happen when port reuse is checked for a port number that is being listened to. Fixes: 19b752a1 ("IB/cma: Allow port reuse for rdma_id") Signed-off-by:

Add new entry to the RDMA-CM configfs that allows users to select default TOS for RDMA-CM QPs. This is useful for users that want to control the TOS for legacy applications without changing their code. Application that sets the TOS explicitly using the rdma_set_option API will continue to work as expected, meaning overriding the configfs value.
