The mlx4 WQ is implemented with HW QP without special HW object. Current implementation which tried to reuse the code did it with common QP creation flows. Such decision caused to the absence of mlx4_ib_wq struct, which is needed to ensure proper allocation of ib_wq inside of IB/core. Separate create_qp_common() to pure QP flow and to create_rq() for RWQ.

This patch is a part of a series that extends kernel ABI to allow to pass tagged user pointers (with the top byte set to something else other than 0x00) as syscall arguments. mlx4_get_umem_mr() uses provided user pointers for vma lookups, which can only by done with untagged pointers.

由 Will Deacon 提交于
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

由 Håkon Bugge 提交于
Using CX-3 virtual functions, either from a bare-metal machine or pass-through from a VM, MAD packets are proxied through the PF driver. Since the VF drivers have separate name spaces for MAD Transaction Ids (TIDs), the PF driver has to re-map the TIDs and keep the book keeping in a cache. Following the RDMA Connection Manager (CM) protocol, it is clear when an entry has to evicted form the cache. But life is not perfect, remote peers may die or be rebooted. Hence, it's a timeout to wipe out a cache entry, when the PF driver assumes the remote peer has gone. During workloads where a high number of QPs are destroyed concurrently, excessive amount of CM DREQ retries has been observed The problem can be demonstrated in a bare-metal environment, where two nodes have instantiated 8 VFs each. This using dual ported HCAs, so we have 16 vPorts per physical server. 64 processes are associated with each vPort and creates and destroys one QP for each of the remote 64 processes. That is, 1024 QPs per vPort, all in all 16K QPs. The QPs are created/destroyed using the CM. When tearing down these 16K QPs, excessive CM DREQ retries (and duplicates) are observed. With some cat/paste/awk wizardry on the infiniband_cm sysfs, we observe as sum of the 16 vPorts on one of the nodes: cm_rx_duplicates: dreq 2102 cm_rx_msgs: drep 1989 dreq 6195 rep 3968 req 4224 rtu 4224 cm_tx_msgs: drep 4093 dreq 27568 rep 4224 req 3968 rtu 3968 cm_tx_retries: dreq 23469 Note that the active/passive side is equally distributed between the two nodes. Enabling pr_debug in cm.c gives tons of: [171778.814239] <mlx4_ib> mlx4_ib_multiplex_cm_handler: id{slave: 1,sl_cm_id: 0xd393089f} is NULL! By increasing the CM_CLEANUP_CACHE_TIMEOUT from 5 to 30 seconds, the tear-down phase of the application is reduced from approximately 90 to 50 seconds. Retries/duplicates are also significantly reduced: cm_rx_duplicates: dreq 2460 [] cm_tx_retries: dreq 3010 req 47 Increasing the timeout further didn't help, as these duplicates and retries stems from a too short CMA timeout, which was 20 (~4 seconds) on the systems. By increasing the CMA timeout to 22 (~17 seconds), the numbers fell down to about 10 for both of them. Adjustment of the CMA timeout is not part of this commit.

The commit cited below replaced rdma_create_ah with mlx4_ib_create_slave_ah when creating AHs for the paravirtualized special QPs. However, this change also required replacing rdma_destroy_ah with mlx4_ib_destroy_ah in the affected flows. The commit missed 3 places where rdma_destroy_ah should have been replaced with mlx4_ib_destroy_ah. As a result, the pd usecount was decremented when the ah was destroyed -- although the usecount was NOT incremented when the ah was created. This caused the pd usecount to become negative, and resulted in the WARN_ON stack trace below when the mlx4_ib.ko module was unloaded: WARNING: CPU: 3 PID: 25303 at drivers/infiniband/core/verbs.c:329 ib_dealloc_pd+0x6d/0x80 [ib_core] Modules linked in: rdma_ucm rdma_cm iw_cm ib_cm ib_umad mlx4_ib(-) ib_uverbs ib_core mlx4_en mlx4_core nfsv3 nfs fscache configfs xt_conntrack nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 libcrc32c ipt_REJECT nf_reject_ipv4 tun ebtable_filter ebtables ip6table_filter ip6_tables iptable_filter bridge stp llc dm_mirror dm_region_hash dm_log dm_mod dax rndis_wlan rndis_host coretemp kvm_intel cdc_ether kvm usbnet iTCO_wdt iTCO_vendor_support cfg80211 irqbypass lpc_ich ipmi_si i2c_i801 mii pcspkr i2c_core mfd_core ipmi_devintf i7core_edac ipmi_msghandler ioatdma pcc_cpufreq dca acpi_cpufreq nfsd auth_rpcgss nfs_acl lockd grace sunrpc ip_tables ext4 mbcache jbd2 sr_mod cdrom ata_generic pata_acpi mptsas scsi_transport_sas mptscsih crc32c_intel ata_piix bnx2 mptbase ipv6 crc_ccitt autofs4 [last unloaded: mlx4_core] CPU: 3 PID: 25303 Comm: modprobe Tainted: G W I 5.0.0-rc1-net-mlx4+ #1 Hardware name: IBM -[7148ZV6]-/Node 1, System Card, BIOS -[MLE170CUS-1.70]- 09/23/2011 RIP: 0010:ib_dealloc_pd+0x6d/0x80 [ib_core] Code: 00 00 85 c0 75 02 5b c3 80 3d aa 87 03 00 00 75 f5 48 c7 c7 88 d7 8f a0 31 c0 c6 05 98 87 03 00 01 e8 07 4c 79 e0 0f 0b 5b c3 <0f> 0b eb be 0f 0b eb ab 90 66 2e 0f 1f 84 00 00 00 00 00 66 66 66 RSP: 0018:ffffc90005347e30 EFLAGS: 00010282 RAX: 00000000ffffffea RBX: ffff8888589e9540 RCX: 0000000000000006 RDX: 0000000000000006 RSI: ffff88885d57ad40 RDI: 0000000000000000 RBP: ffff88885b029c00 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000001 R11: 0000000000000004 R12: ffff8887f06c0000 R13: ffff8887f06c13e8 R14: 0000000000000000 R15: 0000000000000000 FS: 00007fd6743c6740(0000) GS:ffff88887fcc0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000ed1038 CR3: 00000007e3156000 CR4: 00000000000006e0 Call Trace: mlx4_ib_close_sriov+0x125/0x180 [mlx4_ib] mlx4_ib_remove+0x57/0x1f0 [mlx4_ib] mlx4_remove_device+0x92/0xa0 [mlx4_core] mlx4_unregister_interface+0x39/0x90 [mlx4_core] mlx4_ib_cleanup+0xc/0xd7 [mlx4_ib] __x64_sys_delete_module+0x17d/0x290 ? trace_hardirqs_off_thunk+0x1a/0x1c ? do_syscall_64+0x12/0x180 do_syscall_64+0x4a/0x180 entry_SYSCALL_64_after_hwframe+0x49/0xbe Fixes: 5e62d5ff ("IB/mlx4: Create slave AH's directly") Signed-off-by: NJack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: NLeon Romanovsky <leonro@mellanox.com> Signed-off-by: NJason Gunthorpe <jgg@mellanox.com>
