2006-09-22IB/ipath: add serial number to hardware freeze error messageBryan O'Sullivan
Also added the word "Hardware" after "Fatal" to make it more obvious that it's hardware, not software. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: support new QLogic product naming schemeBryan O'Sullivan

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
Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
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: merge ipath_core and ib_ipath driversBryan O'Sullivan
There is little point in keeping the two drivers separate, so we are merging them. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: drop requirement that PIO buffers be mmaped write-onlyBryan O'Sullivan
Some userlands try to mmap these pages read-write, so accommodate them. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: fix handling of kpiobufsBryan O'Sullivan
Change comment: no longer imply that user can set ipath_kpiobufs to zero. Actually set ipath_kpiobufs from parameter. Previously only altered per-device ipath_lastport_piobuf, which was over-written in chip init. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: fix for crash on module unload, if cfgports < portcntBryan O'Sullivan
Allocate enough pointers for all possible ports, to avoid problems in cleanup/unload. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-09-22IB/ipath: More changes to support InfiniPath on PowerPC 970 systemsBryan O'Sullivan
Ordering of writethrough store buffers needs to be forced, and we need to use ifdef to get writethrough behavior to InfiniPath buffers, because there is no generic way to specify that at this time (similar to code in char/drm/drm_vm.c and block/z2ram.c).

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>
2006-09-22IB/uverbs: Allow resize CQ operation to return driver-specific dataRalph Campbell
Add a ib_uverbs_resize_cq_resp.driver_data field so that low-level drivers can return data from a resize CQ operation to userspace. Have ib_uverbs_resize_cq() only copy the cqe field, to avoid having to bump the userspace ABI. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ehca: Add driver for IBM eHCA InfiniBand adaptersHeiko J Schick
Add a driver for IBM GX bus InfiniBand adapters, which are usable with some pSeries/System p systems. Signed-off-by: Heiko J Schick <schickhj.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/srp: Add port/device attributesIshai Rabinovitz
Add local_ib_device and local_ib_port attributes to srp scsi_host. These are needed when we want to connect to the same target through multiple distinct ports. Signed-off-by: Ishai Rabinovitz <ishai@mellanox.co.il> Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Signed-off-by: James Lentini <jlentini@netapp.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/uverbs: Fix lockdep warning when QP is created with 2 CQsRoland Dreier
Lockdep warns when userspace creates a QP that uses different CQs for send completions and receive completions, because both CQs are locked and their mutexes belong to the same lock class. However, we know that the mutexes are distinct and the nesting is safe (there is no possibility of AB-BA deadlock because the mutexes are locked with down_read()), so annotate the situation with SINGLE_DEPTH_NESTING to get rid of the lockdep warning. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/uverbs: Use idr_read_cq() where appropriateRoland Dreier
There were two functions that open-coded idr_read_cq() in terms of idr_read_uobj() rather than using the helper. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipoib: Fix flush/start xmit race (from code review)Michael S. Tsirkin
Prevent flush task from freeing the ipoib_neigh pointer, while ipoib_start_xmit() is accessing the ipoib_neigh through the pointer it has loaded from the skb's hardware address. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/mthca: Don't use privileged UAR for kernel accessMichael S. Tsirkin
Make kernel use UAR2 instead of UAR1 for hardware access: this adds sanity checking from the hardware side, without any performance cost. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/mthca: Fix lid used for sending trapsJack Morgenstein
The SM LID used to send traps to is incorrectly set to port LID. This is a regression from 2.6.17 -- after a PortInfo MAD is received, no traps are sent to the SM LID. The traps go to the loopback interface instead, and are dropped there. The SM LID should be taken from the sm_lid of the PortInfo response. The bug was introduced by commit 12bbb2b7be7f5564952ebe0196623e97464b8ac5: IB/mthca: Add client reregister event generation Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Michael S.
