* IB/ipath: Update copyright dates for files changed in 2008Ralph Campbell2008-04-161-1/+1

* IB/ipath: Misc sparse warning cleanupArthur Jones2008-04-161-1/+2
| | | | | | | | | | Recent sparse versions and kernel cleanups knock down the false positive rate of the ipath driver code to a point where having it be sparse clean is worthwhile. Here we fixup the sparse warnings. Some of these warnings (and the impetus to run sparse again) are due to work by Roland Dreier.

* IB/ipath: Fix comments for ipath_create_srq()Ralph Campbell2008-01-251-2/+2
| | | | | | | During a code review, someone noticed the comments didn't match the code. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: Normalize error return codes for posting work requestsRalph Campbell2007-11-201-1/+1
| | | | | | | | | The error codes for ib_post_send(), ib_post_recv(), and ib_post_srq_recv() were inconsistent. Use EINVAL for too many SGEs and ENOMEM for too many WRs. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: Fix offset returned to ibv_modify_srq()Ralph Campbell2007-11-201-17/+25
| | | | | | | | The wrong offset was being returned to libipathverbs so that when ibv_modify_srq() calls mmap(), it always fails. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: Add barrier before updating WC head in shared memoryRalph Campbell2007-07-091-0/+2
| | | | | | | | | Add a barrier to make sure the CPU doesn't reorder writes to memory, since user programs can be polling on the head index update and the entry should be written before that. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/ipath: Don't corrupt pending mmap list when unmapped objects are freedRobert Walsh2007-04-301-29/+26
| | | | | | | | | | | | Fix the pending mmap code so it doesn't corrupt the list of pending mmaps and crash the machine when pending mmaps are destroyed without first being mapped. Also, remove an unused variable, and use standard kernel lists instead of our own homebrewed linked list implementation to keep the pending mmap list.

* IB/ipath: Performance improvements via mmap of queuesRalph Campbell2006-09-221-90/+150
| | | | | | | | | | 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>
* IB/uverbs: Pass userspace data to modify_srq and modify_qp methodsRalph Campbell2006-09-221-1/+3
| | | | | | | | | | 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>
* [PATCH] IB/ipath: enforce device resource limitsBryan O'Sullivan2006-07-011-12/+35
| | | | | | | | | | | | | 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.
