| * | IB/ipath: Change UD to queue work requests like RC & UCRalph Campbell2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code to post UD sends tried to process work requests at the time ib_post_send() is called without using a WQE queue. This was fine as long as HW resources were available for sending a packet. This patch changes UD to be handled more like RC and UC and shares more code.

| * | IB/ipath: iba6110 rev4 GPIO counters supportArthur Jones2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On iba6110 rev4, support for three more IB counters were added. The LocalLinkIntegrityError counter, the ExcessiveBufferOverrunErrors counter and support for error counting of flow control packets on an invalid VL. These counters trigger GPIO interrupts and the sw keeps track of the counts. Since we also use GPIO interrupts to signal packet reception, we need to turn off the fast interrupts, or we risk losing a GPIO interrupt.

| * | IB/ehca: Fix clipping of device limits to INT_MAXRoland Dreier2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Doing min_t(int, foo, INT_MAX) doesn't work correctly, because if foo is bigger than INT_MAX, then when treated as a signed integer, it will become negative and hence such an expression is just an elaborate NOP. Fix such cases in ehca to do min_t(unsigned, foo, INT_MAX) instead. This fixes negative reported values for max_cqe, max_pd and max_ah: Before: max_cqe: -64 max_pd: -1 max_ah: -1 After: max_cqe: 2147483647 max_pd: 2147483647 max_ah: 2147483647 Based on a bug report and fix from Anton Blanchard <anton@samba.org>.

| * | IB/mthca: Use mmiowb() to avoid firmware commands getting jumbled upRoland Dreier2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firmware commands are sent to the HCA by writing multiple words to a command register block. Access to this block of registers is serialized with a mutex. However, on large SGI systems, problems were seen with multiple CPUs issuing FW commands at the same time, because the writes to the register block may be reordered within the system interconnect and reach the HCA in a different order than they were issued (even with the mutex). Fix this by adding an mmiowb() before dropping the mutex. Tested-by: Arthur Kepner <akepner@sgi.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * | IB/cm: Modify interface to send MRAs in response to duplicate messagesSean Hefty2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IB CM provides a message received acknowledged (MRA) message that can be sent to indicate that a REQ or REP message has been received, but will require more time to process than the timeout specified by those messages. In many cases, the application may not know how long it will take to respond to a CM message, but the majority of the time, it will usually respond before a retry has been sent. Rather than sending an MRA in response to all messages just to handle the case where a longer timeout is needed, it is more efficient to queue the MRA for sending in case a duplicate message is received. This avoids sending an MRA when it is not needed, but limits the number of times that a REQ or REP will be resent. It also provides for a simpler implementation than generating the MRA based on a timer event. (That is, trying to send the MRA after receiving the first REQ or REP if a response has not been generated, so that it is received at the remote side before a duplicate REQ or REP has been received) Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
| * | IB/mthca: Increase max number of QPs per multicast group to 56Roland Dreier2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Increase the number of QPs allowed per multicast group from 8 to 56.

| * | IB/umad: Fix bit ordering and 32-on-64 problems on big endian systemsRoland Dreier2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The declaration of struct ib_user_mad_reg_req.method_mask[] exported to userspace was an array of __u32, but the kernel internally treated it as a bitmap made up of longs. This makes a difference for 64-bit big-endian kernels, where numbering the bits in an array of__u32 gives: |31.....0|63....31|95....64|127...96| while numbering the bits in an array of longs gives: |63..............0|127............64| 64-bit userspace can handle this by just treating method_mask[] as an array of longs, but 32-bit userspace is really stuck: the meaning of the bits in method_mask[] depends on whether the kernel is 32-bit or 64-bit, and there's no sane way for userspace to know that. Fix this by updating <rdma/ib_user_mad.h> to make it clear that method_mask[] is an array of longs, and using a compat_ioctl method to convert to an array of 64-bit longs to handle the 32-on-64 problem. This fixes the interface description to match existing behavior (so working binaries continue to work) in almost all situations, and gives consistent semantics in the case of 32-bit userspace that can run on either a 32-bit or 64-bit kernel, so that the same binary can work for both 32-on-32 and 32-on-64 systems.

| * | IB/umad: Add P_Key index supportRoland Dreier2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for setting the P_Key index of sent MADs and getting the P_Key index of received MADs. This requires a change to the layout of the ABI structure struct ib_user_mad_hdr, so to avoid breaking compatibility, we default to the old (unchanged) ABI and add a new ioctl IB_USER_MAD_ENABLE_PKEY that allows applications that are aware of the new ABI to opt into using it. We plan on switching to the new ABI by default in a year or so, and this patch adds a warning that is printed when an application uses the old ABI, to push people towards converting to the new ABI.

If this is a second request, it seems like it would interfere with process_join_error() since group->last_join won't point to the member at the head of the pending_list. The sequence would thus be: 1. ib_sa_join_multicast() puts member1 on head of pending_list and starts work thread 2. mcast_work_handler() calls send_join() which sets group->last_join to member1 3. ib_sa_join_multicast() puts member2 on head of pending_list 4. join operation for member1 receives failures response from SA. 5. join_handler() is called with error status 6. process_join_error() fails to process member1 since it doesn't match the first entry in the group->pending_list. The impact is that the failed join request is tossed. The second request is processed, and after it completes, the original request ends up being retried. This change also results in join requests being processed in FIFO order.

I had to look closely to see the "Port 1 is not active" message within all the debug: eHCA Infiniband Device Driver (Rel.: SVNEHCA_0022) eHCA scaling code enabled ehca D.001.DQDXYCB-P1-C9: PU0006 EHCA_ERR:ehca_define_sqp Port 1 is not active. ehca D.001.DQDXYCB-P1-C9: PU0006 EHCA_ERR:ehca_create_qp ehca_define_sqp() failed rc=ffffffffffffffff ib_mad: Couldn't create ib_mad QP1 ib_mad: Couldn't open ehca0 port 1 ehca D.001.DQDXYCB-P1-C9: PU0006 EHCA_ERR:ehca_alloc_fmr unsupported fmr_attr->page_shift=9 ehca D.001.DQDXYCB-P1-C9: PU0006 EHCA_ERR:ehca_alloc_fmr rc=ffffffffffffffea pd=c000000b4b5b2420 mr_access_flags=7 fmr_attr=c0000005afd37394 fmr_create failed for FMR 0 Remove a few debug statements so that things are clearer: eHCA Infiniband Device Driver (Rel.: SVNEHCA_0022) eHCA scaling code enabled ehca D.001.DQDXYCB-P1-C9: PU0006 EHCA_ERR:ehca_define_sqp Port 1 is not active. ib_mad: Couldn't create ib_mad QP1 ib_mad: Couldn't open ehca0 port 1 ehca D.001.DQDXYCB-P1-C9: PU0006 EHCA_ERR:ehca_alloc_fmr unsupported fmr_attr->page_shift=9 fmr_create failed for FMR 0 Signed-off-by: Anton Blanchard <anton@samba.org> Acked-by: Hoang-Nam Nguyen <hnguyen@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | mlx4_srq_query() returns a big-endian 16-bit value through an int *, which screws up sparse checking. Fix this so that a CPU-endian value is returned. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * | IB/mthca: Enable MSI-X by defaultMichael S. Tsirkin2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recover from MSI-X errors by automatically falling back on regular interrupt, instead of asking the user to do this manually. This makes it possible to enable MSI-X by default, and will make it possible to get rid of the msi_x module option in the future. Signed-off-by: Michael S.
