* IB/mthca: Use IRQ safe locks to protect allocation bitmapsRoland Dreier2006-08-311-4/+11
| | | | | | | | | | | It is supposed to be OK to call mthca_create_ah() and mthca_destroy_ah() from any context. However, for mem-full HCAs, these functions use the mthca_alloc() and mthca_free() bitmap helpers, and those helpers use non-IRQ-safe spin_lock() internally. Lockdep correctly warns that this could lead to a deadlock. Fix this by changing mthca_alloc() and mthca_free() to use spin_lock_irqsave(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/mthca: Update HCA firmware revisionsMichael S. Tsirkin2006-08-231-3/+3

* IB/mthca: No userspace SRQs if HCA doesn't have SRQ supportRoland Dreier2006-08-181-5/+6
| | | | | | | | | | | Leave all SRQ methods out of the device's uverbs_cmd_mask if the device doesn't have SRQ support (because of ancient firmware) so that we don't allow userspace to call the driver's create_srq method. This fixes a userspace-triggerable oops caused by ib_uverbs_create_srq() following the device's ->create_srq function pointer, which will be NULL if the device doesn't support SRQs.

* IB/mthca: Fix potential AB-BA deadlock with CQ locksRoland Dreier2006-08-112-14/+32
| | | | | | | | | | | | | | | | | | | | | When destroying a QP, mthca locks both the QP's send CQ and receive CQ. However, the following scenario is perfectly valid: QP_a: send_cq == CQ_x, recv_cq == CQ_y QP_b: send_cq == CQ_y, recv_cq == CQ_x The old mthca code simply locked send_cq and then recv_cq, which in this case could lead to an AB-BA deadlock if QP_a and QP_b were destroyed simultaneously. We can fix this by changing the locking code to lock the CQ with the lower CQ number first, which will create a consistent lock ordering. Also, the second CQ is locked with spin_lock_nested() to tell lockdep that we know what we're doing with the lock nesting. This bug was found by lockdep.

* IB/ipath: ipath_skip_sge() can break if num_sge > 1Ralph Campbell2006-07-241-4/+0
| | | | | | | | | | | ipath_skip_sge() doesn't exactly duplicate the side effects of ipath_copy_sge() if num_sge > 1 since it doesn't decrement ss->num_sge. This could result in the sg_list being accessed out of bounds. Since ipath_skip_sge() is almost always called with num_sge == 1, the original "optimization" is almost never used.

* [PATCH] IB/ipath: fixed bug 9776 for realBryan O'Sullivan2006-07-012-31/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was that I was updating the head register multiple times in the rcvhdrq processing loop, and setting the counter on each update. Since that meant that the tail register was ahead of head for all but the last update, we would get extra interrupts. The fix was to not write the counter value except on the last update. I also changed to update rcvhdrhead and rcvegrindexhead at most every 16 packets, if there were lots of packets in the queue (and of course, on the last packet, regardless). I also made some small cleanups while debugging this. With these changes, xeon/monty typically sees two openib packets per interrupt on sdp and ipoib, opteron/monty is about 1.25 pkts/intr. I'm seeing about 3800 Mbit/s monty/xeon, and 5000-5100 opteron/monty with netperf sdp. Netpipe doesn't show as good as that, peaking at about 4400 on opteron/monty sdp. Plain ipoib xeon is about 2100+ netperf, opteron 2900+, at 128KB Signed-off-by: olson@eng-12.pathscale.com Signed-off-by: Bryan O'Sullivan <bos@pathscale.com> Cc: "Michael S.

| | | | | | | | | | | | | | | | | | | | | | Also count the number of interrupts where that works (fastrcvint). On any interrupt where the port0 head and tail registers are not equal, just call the ipath_kreceive code without reading the interrupt status, thus saving the approximately 0.25usec processor stall waiting for the read to return. If any other interrupt bits are set, or head==tail, take the normal path, but that has been reordered to handle read ahead of pioavail. Also no longer call ipath_kreceive() from ipath_qcheck(), because that just seems to make things worse, and isn't really buying us anything, these days. Also no longer loop in ipath_kreceive(); better to not hold things off too long (I saw many cases where we would loop 4-8 times, and handle thousands (up to 3500) in a single call).

* [PATCH] IB/ipath: allow diags on any unitBryan O'Sullivan2006-07-015-87/+53
| | | | | | | | | | | | | | There is no longer a /dev/ipath_diag file; instead, there's /dev/ipath_diag0, 1, etc. It's still not possible to have diags run on more than one unit at a time, but that's easy to fix at some point.
