-
-       * src/verbs.c (mthca_free_pd): Free pointer to correct structure
-       (we get lucky now, but don't rely on this).
-       * src/mthca.c (mthca_free_context): Free context's PD so we don't
-       leak it.
-
-2006-01-06  Michael S. Tsirkin  <mst at mellanox.co.il>
-
-       * src/verbs.c (mthca_destroy_qp): Jack Morgenstein has discovered
-       the following race condition in libmthca:
-
-       Thread A destroys QP A at the kernel side by calling
-       ibv_cmd_destroy_qp, but its time-slice is over before removing it
-       from the user-space qp_table removal.
-
-       Thread B allocates QP B, receiving a QP number that matches the
-       just-destroyed QP A in the low 16 bits.  Thread B will now
-       over-write the slot in qp_table which was used for QP A.
-
-       Thread A wakes up and clears qp_table slot, in effect removing QP
-       B from qp_table.
-
-       As a solution, remove the QP from qp_table before calling
-       ibv_cmd_destroy_qp.  This also makes sense since operations are
-       performed in the reverse order in create_qp.
-
-       * src/cq.c (handle_error_cqe): Fill in vendor_err field for
-       completions with error.
-
-2006-01-05  Jack Morgenstein  <jackm at mellanox.co.il>
-
-       * src/verbs.c (mthca_destroy_qp, mthca_destroy_srq): Free QP/SRQ
-       object to avoid memory leak.
-
-2005-12-15  Jack Morgenstein  <jackm at mellanox.co.il>
-
-       * src/cq.c (mthca_cq_clean): When cleaning up a CQ, we should free
-       an SRQ WQE if and only if the CQE is a receive.
-
-2005-12-15  Michael S. Tsirkin  <mst at mellanox.co.il>
-
-       * src/qp.c (mthca_store_qp): Don't increment qp_table ref count if
-       allocation fails.
-
-2005-11-29  Michael S. Tsirkin  <mst at mellanox.co.il>
-
-       * src/qp.c (mthca_arbel_post_send): Add handling for posting long
-       send lists for mem-free HCAs.
-       * src/qp.c (mthca_tavor_post_recv): Fix posting long receive
-       lists: nreq is set to zero early on, so we need to use
-       MTHCA_TAVOR_MAX_WQES_PER_RECV_DB as the increment to rq.head.
-
-2005-11-28  Roland Dreier  <roland at cisco.com>
-
-       * src/qp.c (mthca_init_qp_indices): Set qp->sq.last and
-       qp->rq.last so that QP is fully reset when the indices are
-       reinited on transition to RESET state.
-       (mthca_tavor_post_send, mthca_arbel_post_send): Don't create an
-       inline send segment when a work request is posted that has the
-       inline flag set but no gather entries included.
-
-2005-11-09  Roland Dreier  <roland at cisco.com>
-
-       * src/srq.c (mthca_tavor_post_srq_recv), src/qp.c
-       (mthca_tavor_post_recv): Fix bugs in long receive list handling;
-       need to set nreq to 0 and not put 256 credits into the second
-       doorbell word.
-
-       * src/cq.c (mthca_cq_clean): Handle case where CQ indices wrap
-       around by treating signed comparisons of prod_index and
-       cq->cons_index carefully.
-
-2005-11-09  Michael S. Tsirkin  <mst at mellanox.co.il>
-
-       * src/srq.c (mthca_tavor_post_srq_recv), src/qp.c
-       (mthca_tavor_post_recv): Tavor requires that a doorbell be rung
-       at least every 256 receives, so add code to ring doorbells in the
-       middle of posting a huge list of receives.
-       
-       * src/qp.c (mthca_tavor_post_send, mthca_tavor_post_send): When
-       posting atomic operations, could wqe size in "octowords" correctly.
-
-       * src/ah.c (mthca_alloc_av): Don't free ah if page allocation
-       fails.  It will be freed where it's allocated, in the caller.
-
-2005-11-08  Roland Dreier  <roland at cisco.com>
-
-       * src/qp.c, src/verbs.c, src/mthca.h: Delegate setting of QP
-       capabilities (max_sge, max_inline_data, etc) to kernel.
-
-2005-11-04  Roland Dreier  <roland at cisco.com>
-
-       * src/verbs.c (mthca_destroy_qp): Clean CQEs when we destroy a QP.
-       (mthca_modify_qp): Clean CQEs when we move a QP to RESET state,
-       and reset QP index pointers.
-
-       * src/cq.c (mthca_cq_clean): Add function to clean out CQEs for
-       QPs that are being destroyed or reset.
-
-2005-10-30  Roland Dreier  <roland at cisco.com>
-
-       * src/srq.c (wqe_to_link): Change to use an offset of 12 (the imm
-       field), because posting an SRQ WQE may actually change the ee_nds
-       field and still cause free list corruption.  A receive WQE will
-       never have immediate data, so using imm is definitely safe.
-
-2005-10-25  Roland Dreier  <roland at cisco.com>
-
-       * Release version 1.0-rc4.
-
-2005-10-23  Roland Dreier  <roland at cisco.com>
-
-       * src/qp.c (mthca_return_cap, mthca_alloc_qp_buf), src/verbs.c
-       (mthca_create_qp): Explicitly pass QP type to functions used while
-       creating QP, since we can't rely on ibv_qp.qp_type to be set until
-       after we return.  This fixes breakage with UD QPs introduced in
-       the last change below.
-
-2005-10-19  Roland Dreier  <roland at cisco.com>
-
-       * src/mthca.h, src/verbs.c (mthca_create_qp), src/qp.c
-       (mthca_tavor_post_send, mthca_arbel_post_send, mthca_alloc_qp_buf,
-       mthca_return_cap): Eliminate struct mthca_qp.qpt field and use
-       struct ibv_qp.qp_type instead (now that that field has been added
-       in libibverbs).
-
-2005-10-18  Roland Dreier  <roland at cisco.com>
-
-       * src/cq.c (handle_error_cqe, mthca_poll_one): Dump CQEs for local
-       QP operation errors instead of all error statuses.
-
-2005-10-06  Roland Dreier  <roland at cisco.com>
-
-       * src/srq.c (mthca_free_srq_wqe): Pass index instead of WQE
-       address.  The only caller already has the index handy, so there's
-       no need to recalculate it here.
-       
-       * src/srq.c (mthca_tavor_post_srq_recv,
-       mthca_arbel_post_srq_recv): Add an extra check so that we report
-       the SRQ as full before using the one extra WQE we need internally.
-
-2005-10-05  Roland Dreier  <roland at cisco.com>
-
-       * src/verbs.c (mthca_modify_srq): Fill in mthca_modify_srq().
-
-2005-09-29  Roland Dreier  <roland at cisco.com>
-
-       * src/verbs.c (mthca_query_device): Update to match new libibverbs
-       API that requires device-specific libraries to format firmware version.
-
-2005-09-25  Roland Dreier  <roland at cisco.com>
-
-       * src/cq.c, src/mthca.c, src/mthca.h, src/verbs.c: Update to match
-       new libibverbs API introduced with completion channel implementation.
-
-2005-09-13  Roland Dreier  <roland at cisco.com>
-
-       * src/qp.c (mthca_tavor_post_send, mthca_tavor_post_recv,
-       mthca_arbel_post_send), src/srq.c (mthca_tavor_post_srq_recv):
-       Apply Michael S. Tsirkin's patch to fix linking of WQEs on
-       mem-free HCAs.  While we're at it, simplify the Tavor WQE posting
-       code as well -- there's no need for a conditional, just always lik
-       the previous WQE.
-
-2005-09-07  Roland Dreier  <roland at cisco.com>
-
-       * src/mthca.h: Get rid of ntohll() and htonll() now that
-       libibverbs defines them in .
-
-2005-08-31  Roland Dreier  <roland at cisco.com>
-
-       * src/memfree.c (mthca_free_db): When we free a doorbell record,
-       really mark it as free in the free bitmap.  This we we don't
-       eventually run out of doorbells if a consumer creates and frees a
-       lot of objects.
-
-       * src/memfree.c (mthca_alloc_db): Introduce MTHCA_FREE_MAP_SIZE so
-       that we iterate over the correct number of entries in the mem-free
-       doorbell record free maps.  This fixes some off-by-a-factor-of-8
-       bugs that could lead to crashes.
-
-       * src/verbs.c (mthca_create_cq): In the mem-free case, when
-       creating a CQ fails to allocate an arm doorbell, make sure we free
-       the set CI doorbell instead of the (non-existent) arm doorbell.
