[PATCH OLK-5.10] RDMA/hns: Fix the valid QP bank set to improve performance
by Chengchang Tang 14 Nov '24

14 Nov '24

From: wenglianfa <wenglianfa(a)huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB2HJE ---------------------------------------------------------------------- QP banks 0, 1, 4, and 5 use one HW FIFO, while QP banks 2, 3, 6, and 7 use another. Currently, if HNS_ROCE_CAP_FLAG_LIMIT_BANK is set, only QP banks 0, 1, 4, and 5 are used, resulting in a single HW FIFO being utilized. Instead, it is proposed to use QP banks 0, 1, 6, and 7 to leverage different FIFOs and improve performance.
