2006-09-28IB/ipath: Flush RWQEs if access error or invalid error seenBryan O'Sullivan
If the receiver goes into the error state, we need to flush the posted receive WQEs. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-28IB/ipath: Limit # of packets sent without an ACK receivedBryan O'Sullivan
The sender requests an ACK every 1/2 MB to avoid retransmit timeouts that were causing MVAPICH mod_bw to fail after a predictable number of sends. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-09-22IB/ipath: remove stale references to userspace SMABryan O'Sullivan
When we first submitted a userspace subnet management agent, it was rejected, so we left it out of the final driver submission. This patch removes a number of vestigial references to it. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: simplify debugging code after ipath_core and ib_ipath mergerBryan O'Sullivan

2006-09-22IB/ipath: simplify layering codeBryan O'Sullivan
A lot of ipath layer code was only called in one place. Now that the ipath_core and ib_ipath drivers are merged, it's more sensible to simply inline the simple stuff that the layer code was doing. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: Performance improvements via mmap of queuesRalph Campbell
Improve performance of userspace post receive, post SRQ receive, and poll CQ operations for ipath by allowing userspace to directly mmap() receive queues and completion queues. This eliminates the copying between userspace and the kernel in the data path. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/uverbs: Pass userspace data to modify_srq and modify_qp methodsRalph Campbell
Pass a struct ib_udata to the low-level driver's ->modify_srq() and ->modify_qp() methods, so that it can get to the device-specific data passed in by the userspace driver. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-07-01[PATCH] IB/ipath: namespace cleanup: replace ips with ipathBryan O'Sullivan
Remove ips namespace from infinipath drivers. This renames ips_common.h to ipath_common.h. Definitions, data structures, etc. that were not used by kernel modules have moved to user-only headers. All names including ips have been renamed to ipath. Some names have had an ipath prefix added.

2006-07-01[PATCH] IB/ipath: ignore receive queue size if SRQ is specifiedBryan O'Sullivan
The receive work queue size should be ignored if the QP is created to use a shared receive queue according to the IB spec.

2006-07-01[PATCH] IB/ipath: rC receive interrupt performance changesBryan O'Sullivan
This patch separates QP state used for sending and receiving RC packets so the processing in the receive interrupt handler can be done mostly without locks being held. ACK packets are now sent without requiring synchronization with the send tasklet.

2006-07-01[PATCH] IB/ipath: enforce device resource limitsBryan O'Sullivan
These limits are somewhat artificial in that we don't actually have any device limits. However, the verbs layer expects that such limits exist and are enforced, so we make up arbitrary (but sensible) limits.
