When processing a REG_MR work request, if fw supports the FW_RI_NSMR_TPTE_WR work request, and if the page list for this registration is <= 2 pages, and the current state of the mr is INVALID, then use FW_RI_NSMR_TPTE_WR to pass down a fully populated TPTE for FW to write. This avoids FW having to do an async read of the TPTE blocking the SQ until the read completes. To know if the current MR state is INVALID or not, iw_cxgb4 must track the state of each fastreg MR. The c4iw_mr struct state is updated as REG_MR and LOCAL_INV WRs are posted and completed, when a reg_mr is destroyed, and when RECV completions are processed that include a local invalidation. This optimization increases small IO IOPS for both iSER and NVMF. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com> |
