That said, I suspect the sequence in question should probably use "mod_delayed_work()". I just did the minimal "don't use deprecated functions" fixup, though. * tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband: (45 commits) IB/qib: Fix local access validation for user MRs mlx4_core: Disable SENSE_PORT for multifunction devices mlx4_core: Clean up enabling of SENSE_PORT for older (ConnectX-1/-2) HCAs mlx4_core: Stash PCI ID driver_data in mlx4_priv structure IB/srp: Avoid having aborted requests hang IB/srp: Fix use-after-free in srp_reset_req() IB/qib: Add a qib driver version RDMA/nes: Fix compilation error when nes_debug is enabled RDMA/nes: Print hardware resource type RDMA/nes: Fix for crash when TX checksum offload is off RDMA/nes: Cosmetic changes RDMA/nes: Fix for incorrect MSS when TSO is on RDMA/nes: Fix incorrect resolving of the loopback MAC address mlx4_core: Fix crash on uninitialized priv->cmd.slave_sem mlx4_core: Trivial cleanups to driver log messages mlx4_core: Trivial readability fix: "0X30" -> "0x30" IB/mlx4: Create paravirt contexts for VFs when master IB driver initializes mlx4: Modify proxy/tunnel QP mechanism so that guests do no calculations mlx4: Paravirtualize Node Guids for slaves mlx4: Activate SR-IOV mode for IB ...
| * RDMA/cxgb4: Fix error handling in create_qp()Emil Goode2012-09-301-24/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variable ret is assigned return values in a couple of places, but its value is never returned. This patch makes use of the ret variable so that the caller get correct error codes returned. The following changes are also introduced: - The alloc_oc_sq function can return -ENOSYS or -ENOMEM so we want to get the return value from it. - Change the label names to improve readability.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 01e7da6ba53c ("RDMA/cxgb4: Make sure flush CQ entries are collected on connection close") introduced a potential problem where a CQ's comp_handler can get called simultaneously from different places in the iw_cxgb4 driver. This does not comply with Documentation/infiniband/core_locking.txt, which states that at a given point of time, there should be only one callback per CQ should be active. This problem was reported by Parav Pandit <Parav.Pandit@Emulex.Com>. Based on discussion between Parav Pandit and Steve Wise, this patch fixes the above problem by serializing the calls to a CQ's comp_handler using a spin_lock.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | At the time when a peer closes the connection, iw_cxgb4 will not send a cq event if ibqp.uobject exists. In that case, its possible for a user application to get blocked in ibv_get_cq_event(). To resolve this, call the cq's comp_handler to unblock any read from ibv_get_cq_event(). This will trigger userspace to poll the cq and collect flush status completions for any pending work requests.

| | | | | | | | | | | | | | | | Move the connection setup/teardown paths to the workq thread removing spin lock/irq disable requirements for these paths. This allows calls down to the LLD for EP and QP state transition actions to be atomic with respect to processing CPL messages coming up from the HW. Namely, calls to rdma_init() and rdma_fini() can now be called with the mutex held avoiding many race conditions with the abort path. The QP spinlock is still used but only to manipulate the qp state. This allows the fastpaths, poll, post_send, and pos_recv, to run in the irq context.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | T4 EQ entries are in multiples of 64 bytes. Currently the RDMA SQ and RQ use fixed sized entries composed of 4 EQ entries for the SQ and 2 EQ entries for the RQ. For optimial latency with small IO, we need to change this so the HW only needs to DMA the EQ entries actually used by a given work request. Implementation: - add wq_pidx counter to track where we are in the EQ. cidx/pidx are used for the sw sq/rq tracking and flow control. - the variable part of work requests is the SGL. Add new functions to build the SGL and/or immediate data directly in the EQ memory wrapping when needed. - adjust the min burst size for the EQ contexts to 64B.
