Relevant SA queries are actually "greater than" / "less than", not "greater than or equal" / "less than or equal" as the names imply. (See IB spec 1.2 Vol 1, 15.2.5.16 PATHRECORD/Table 205 PathRecord) Signed-off-by:

If a QP has separate send and receive CQs, then the send CQ will never have receive completions from that QP in it. So when cleaning the send CQ, there's no need to pass in an SRQ pointer, even if the QP is attached to an SRQ. Signed-off-by: -

Trigger device remove and then add when a catastrophic error is detected in hardware. This, in turn, will cause a device reset, which we hope will recover from the catastrophic condition. Since this might interefere with debugging the root cause, add a module option to suppress this behaviour. Signed-off-by:

Split up ipoib_ib_handle_wc() into ipoib_ib_handle_rx_wc() and ipoib_ib_handle_tx_wc() to make the code easier to read. This will also help implement NAPI in the future. Signed-off-by: -

Fast Memory Registration (fmr) is used to register for rdma an sg whose elements are not linearly sequential after dma mapping. The IB verbs layer provides an "all dma memory MR (memory region)" which can be used for RDMA-ing a dma linearly sequential buffer. Change the code to use the dma mr instead of doing fmr when dma mapping produces a single dma entry sg. Signed-off-by:

fix and add some debug prints related to iser handling of memory for rdma. Signed-off-by:

Erez Zilber authored
As iser is able to use at most one rdma operation for the execution of a scsi command, and registration of the sg associated with scsi command has its restrictions, the code checks if an sg is "aligned for rdma". Alignment for rdma is measured in "fmr page" units whose possible resolutions are different between HCAs and can be smaller, equal or bigger to the system page size. When the system page size is bigger than 4KB (eg the default with ia64 kernels) there a bigger chance that an sg would be aligned for rdma if the fmr page size is 4KB. Change the code to create FMR whose pages are of size 4KB and to take that into account when processing the sg. Signed-off-by:

Currently, the data length of a command coming down from scsi-ml is limited only by the size of its sg list (sg_tablesize). The max data length may be different for different page size values. By setting max_sectors, we limit the data length to max_sectors*512 bytes. Signed-off-by:

dma mapping may include a "compaction" of the sg associated with scsi command. Hence, the size of the maximal prefix of the SG which is aligned for rdma must be compared against the length of the dma mapped sg (mem->dma_nents) and not against the size of it before it was mapped (mem->size).

Modifications to the existing rdma header files, core files, drivers, and ulp files to support iWARP, including: - Hook iWARP CM into the build system and use it in rdma_cm. - Convert enum ib_node_type to enum rdma_node_type, which includes the possibility of RDMA_NODE_RNIC, and update everything for this.

Add an iWARP Connection Manager (CM), which abstracts connection management for iWARP devices (RNICs). It is a logical instance of the xx_cm where xx is the transport type (ib or iw). The symbols exported are used by the transport independent rdma_cm module, and are available also for transport dependent ULPs. Signed-off-by:

The implementation assumes that any RMPP request that requires a response uses DS RMPP. Based on the RMPP start-up scenarios defined by the spec, this should be a valid assumption. That is, there is no start-up scenario defined where an RMPP request is followed by a non-RMPP response. By having this assumption we avoid any API changes. In order for a node that supports DS RMPP to communicate with one that does not, RMPP responses assume a new window size of 1 if a DS ACK has not been received. (By DS ACK, I'm referring to the turn-around ACK after the final ACK of the request.) This is a slight spec deviation, but is necessary to allow communication with nodes that do not generate the DS ACK. It also handles the case when a response is sent after the request state has been discarded. Signed-off-by:
