This is completely analogous to the previous asynchronous - event change. - -2005-08-31 Roland Dreier <roland@cisco.com> - - * include/infiniband/kern-abi.h, include/infiniband/verbs.h, - src/cmd.c, src/device.c, src/ibverbs.h, src/init.c, src/verbs.c, - examples/asyncwatch.c: Update to handle new kernel ABI for - avoiding stale asynchronous events. When a CQ, QP or SRQ is - destroyed, the kernel reports the number of events it has given to - userspace, and we wait until we've handled the same number of - events. - - This does introduce a library API change: consumers are now - required to call ibv_put_async_event() to release every - asynchronous event that they retrieve via ibv_get_async_event(). - -2005-08-30 Roland Dreier <roland@cisco.com> - - * man/ibv_asyncwatch.1, man/ibv_devices.1, man/ibv_devinfo.1, - man/ibv_rc_pingpong.1, man/ibv_srq_pingpong.1, - man/ibv_uc_pingpong.1, man/ibv_ud_pingpong.1: Add man pages for - example programs. - - * examples/devinfo.c: Merge with Dotan Barak's vstat tool. |
