The current code loops during rkey/lkey validiation to isolate the MR for the RDMA, which is expensive when the current operation is inside a very large memory region. This fix optimizes rkey/lkey validation routines for user memory regions and fast memory regions. The MR entry can be isolated by shifts/mods instead of looping. The existing loop is preserved for phys memory regions for now. Signed-off-by: Mike Marciniszyn <mike.marciniszyn@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com> |
