qib_compute_aeth - compute the AETH (syndrome + MSN) : the queue pair to compute the AETH for
Returns the AETH.
Definition at line 910 of file qib_qp.c.
qib_create_qp - create a queue pair for a device : the protection domain who's device we create the queue pair for : the attributes of the queue pair : user data for libibverbs.so
Returns the queue pair on success, otherwise returns an errno.
Called by the ib_create_qp() core verbs function.
Definition at line 974 of file qib_qp.c.
qib_destroy_qp - destroy a queue pair : the queue pair to destroy
Returns 0 on success.
Note that this can be called while the QP is actively sending or receiving!
Definition at line 1188 of file qib_qp.c.
qib_error_qp - put a QP into the error state : the QP to put into the error state : the receive completion error to signal if a RWQE is active
Flushes both send and receive work queues. Returns true if last WQE event should be generated. The QP r_lock and s_lock should be held and interrupts disabled. If we are already in error state, just return.
Definition at line 473 of file qib_qp.c.
qib_free_all_qps - check for QPs still in use : the QP table to empty
There should not be any QPs still in use. Free memory for table.
Definition at line 293 of file qib_qp.c.
qib_free_qpn_table - free the QP number table for a device : the QPN table
Definition at line 1248 of file qib_qp.c.
qib_get_credit - flush the send work queue of a QP : the qp who's send work queue to flush : the Acknowledge Extended Transport Header
The QP s_lock should be held.
Definition at line 1264 of file qib_qp.c.
qib_init_qpn_table - initialize the QP number table for a device : the QPN table
Definition at line 1236 of file qib_qp.c.
qib_lookup_qpn - return the QP with the given QPN : the QP table : the QP number to look up
The caller is responsible for decrementing the QP reference count when done.
Definition at line 337 of file qib_qp.c.
qib_modify_qp - modify the attributes of a queue pair : the queue pair who's attributes we're modifying : the new attributes : the mask of attributes to modify : user data for libibverbs.so
Returns 0 on success, otherwise returns an errno.
