Has anyone been able to use ipath with the current latest git everything? The libipathverbs git repository seems to be missing a patch from Roland to make it work with libibverbs.2 in an email titled:
[openib-general] [PATCH 3/7] libipathverbs: Update libipathverbs for new libibverbs driver handling After applying that patch the user space consumers load but we got a kernel oops when we tried to run a test here :< Unable to handle kernel NULL pointer dereference at 0000000000000918 RIP: [<ffffffff88074c76>] :ib_ipath:ipath_mmap+0x37/0x95 PGD 3ad46067 PUD 3ad4f067 PMD 0 Oops: 0000 [1] CPU 0 Modules linked in: usb_storage skge bitrev crc32 ib_ipath k8temp hwmon forcedeth ehci_hcd ohci_hcd usbcore i2c_nforce2 i2c_core ib_uverbs ib_umad ib_mad ib_core Pid: 4009, comm: ib_rdma_lat Not tainted 2.6.20-rc4-gf3a2c3ee-dirty #6 RIP: 0010:[<ffffffff88074c76>] [<ffffffff88074c76>] :ib_ipath:ipath_mmap+0x37/0x95 RSP: 0000:ffff81003aaa3e88 EFLAGS: 00010002 RAX: ffff81003c434000 RBX: 0000000000000910 RCX: 0000000000001000 RDX: 00000000002b3000 RSI: ffff81003bcab440 RDI: ffff81003bc2d840 RBP: ffff81003b7af918 R08: ffff81003aaa3f08 R09: ffff81003aa38c98 R10: ffff81003aa38c90 R11: ffffffff88074c3f R12: 00000000ffffffea R13: ffff81003ac496c0 R14: 00000000f7ee3000 R15: 0000000000001000 FS: 0000000000000000(0000) GS:ffffffff80530000(0063) knlGS:00000000f7d8c6c0 CS: 0010 DS: 002b ES: 002b CR0: 000000008005003b CR2: 0000000000000918 CR3: 000000003aa2f000 CR4: 00000000000006e0 Process ib_rdma_lat (pid: 4009, threadinfo ffff81003aaa2000, task ffff81003c0495e0) Stack: ffff81003b7af918 00000000001000fb 00000000ffffffea ffffffff80250151 ffff81003be9f440 ffff81003bc2d140 0000000000000028 00000000ff99df20 0000000000000000 0000000000000000 ffff81003b87d818 ffff81003dc04840 Call Trace: [<ffffffff80250151>] do_mmap_pgoff+0x4d5/0x739 [<ffffffff8021b54b>] sys32_mmap2+0x76/0x9e [<ffffffff8021a432>] ia32_sysret+0x0/0xa Code: 48 3b 7b 08 75 46 48 3b 53 10 75 40 8b 43 1c 48 39 c1 77 40 RIP [<ffffffff88074c76>] :ib_ipath:ipath_mmap+0x37/0x95 RSP <ffff81003aaa3e88> CR2: 0000000000000918 This is with a PCI-E qlogic card: 0000:03:00.0 InfiniBand: Unknown device 1fc1:0010 (rev 01) Anyone have any clues? One notable thing is that I have a 32 bit user space and a 64 bit kernel. I'll try a 64 bit user space tomorrow in case there is some thing wrong with 32bit compatability... The last time we had these cards working was with OFED 1.1 on 64 bit FC4 using a linus kernel (2.6.18 I think)..
