Revision 42ab01c31526ac1d06d193f81a498bf3cf2acfe4 authored by Jack Morgenstein on 01 December 2008, 18:09:37 UTC, committed by Roland Dreier on 01 December 2008, 18:09:37 UTC
When resizing a CQ, MTTs associated with the old CQE buffer were not freed. As a result, if any app used resize CQ repeatedly, all MTTs were eventually exhausted, which led to all memory registration operations failing until the driver is reloaded. Once the RESIZE_CQ command returns successfully from FW, FW no longer accesses the old CQ buffer, so it is safe to deallocate the MTT entries used by the old CQ buffer. Finally, if the RESIZE_CQ command fails, the MTTs allocated for the new CQEs buffer also need to be de-allocated. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1416>.
