Few things fixed it. 1. Generally, pi == ci, no need for extra checks. 2. The proper initializations in init with ci Fixes: 1b49352f41be ("bus/fslmc: rename portal pi index to consumer index") Cc: stable@dpdk.org Signed-off-by: Youri Querry Acked-by: Hemant Agrawal --- drivers/bus/fslmc/qbman/qbman_portal.c | 14 +++----------- 1 file changed, 3 insertions(+), 11 deletions(-) diff --git a/drivers/bus/fslmc/qbman/qbman_portal.c b/drivers/bus/fslmc/qbman/qbman_portal.c index 77c9d508c4..aedcad9258 100644 --- a/drivers/bus/fslmc/qbman/qbman_portal.c +++ b/drivers/bus/fslmc/qbman/qbman_portal.c @@ -339,17 +339,9 @@ struct qbman_swp *qbman_swp_init(const struct qbman_swp_desc *d) eqcr_pi = qbman_cinh_read(&p->sys, QBMAN_CINH_SWP_EQCR_PI); p->eqcr.pi = eqcr_pi & p->eqcr.pi_ci_mask; p->eqcr.pi_vb = eqcr_pi & QB_VALID_BIT; - if ((p->desc.qman_version & QMAN_REV_MASK) >= QMAN_REV_5000 - && (d->cena_access_mode == qman_cena_fastest_access)) - p->eqcr.ci = qbman_cinh_read(&p->sys, QBMAN_CINH_SWP_EQCR_PI) - & p->eqcr.pi_ci_mask; - else - p->eqcr.ci = qbman_cinh_read(&p->sys, QBMAN_CINH_SWP_EQCR_CI) - & p->eqcr.pi_ci_mask; - p->eqcr.available = p->eqcr.pi_ring_size - - qm_cyc_diff(p->eqcr.pi_ring_size, - p->eqcr.ci & (p->eqcr.pi_ci_mask<<1), - p->eqcr.pi & (p->eqcr.pi_ci_mask<<1)); + p->eqcr.ci = qbman_cinh_read(&p->sys, QBMAN_CINH_SWP_EQCR_CI) + & p->eqcr.pi_ci_mask; + p->eqcr.available = p->eqcr.pi_ring_size; portal_idx_map[p->desc.idx] = p; return p; -- 2.17.1
