commit 3a9565c2a8e4f1b3da698bf6a8af5889dc4fefbd Author: Sreekanth Reddy <[email protected]> AuthorDate: 2026-01-23 16:38:02 +0000 Commit: Sumit Saxena <[email protected]> CommitDate: 2026-01-27 12:13:09 +0000 bnxt_re: Add support to display board_id in ibv_devinfo output Added support to display board_id in ibv_devinfo output. ibv_devinfo util reads the board_id from below sysctl attribute, so added this sysctl attribute. sys.class.infiniband.bnxt_reX.board_id Reviewed by: ssaxena Differential Revision: https://reviews.freebsd.org/D54524 MFC after: 3 days --- sys/dev/bnxt/bnxt_en/bnxt.h | 1 + sys/dev/bnxt/bnxt_en/bnxt_ulp.c | 1 + sys/dev/bnxt/bnxt_en/bnxt_ulp.h | 2 ++ sys/dev/bnxt/bnxt_en/if_bnxt.c | 7 +++++++ sys/dev/bnxt/bnxt_re/main.c | 21 ++++++++++++++++++++- 5 files changed, 31 insertions(+), 1 deletion(-) diff --git a/sys/dev/bnxt/bnxt_en/bnxt.h b/sys/dev/bnxt/bnxt_en/bnxt.h index 5556914fb61e..64482a656e9d 100644 --- a/sys/dev/bnxt/bnxt_en/bnxt.h +++ b/sys/dev/bnxt/bnxt_en/bnxt.h @@ -1340,6 +1340,7 @@ struct bnxt_softc { unsigned long fw_reset_timestamp; struct bnxt_fw_health *fw_health; + char board_partno[64]; }; struct bnxt_filter_info { diff --git a/sys/dev/bnxt/bnxt_en/bnxt_ulp.c b/sys/dev/bnxt/bnxt_en/bnxt_ulp.c index 677c9c99b74e..c6d862a36a9a 100644 --- a/sys/dev/bnxt/bnxt_en/bnxt_ulp.c +++ b/sys/dev/bnxt/bnxt_en/bnxt_ulp.c @@ -463,6 +463,7 @@ static inline void bnxt_set_edev_info(struct bnxt_en_dev *edev, struct bnxt_soft edev->hwrm_bar = bp->hwrm_bar; edev->port_partition_type = bp->port_partition_type; edev->ulp_version = BNXT_ULP_VERSION; + memcpy(edev->board_part_number, bp->board_partno, BNXT_VPD_PN_FLD_LEN - 1); } int bnxt_rdma_aux_device_del(struct bnxt_softc *softc) diff --git a/sys/dev/bnxt/bnxt_en/bnxt_ulp.h b/sys/dev/bnxt/bnxt_en/bnxt_ulp.h index 7d7ecbd2f536..53bb51b07135 100644 --- a/sys/dev/bnxt/bnxt_en/bnxt_ulp.h +++ b/sys/dev/bnxt/bnxt_en/bnxt_ulp.h @@ -127,6 +127,8 @@ struct bnxt_en_dev { struct bnxt_bar_info hwrm_bar; u32 espeed; uint8_t lanes; + #define BNXT_VPD_PN_FLD_LEN 32 + char board_part_number[BNXT_VPD_PN_FLD_LEN]; }; struct bnxt_en_ops { diff --git a/sys/dev/bnxt/bnxt_en/if_bnxt.c b/sys/dev/bnxt/bnxt_en/if_bnxt.c index 94775457b7e3..dea6fd68181e 100644 --- a/sys/dev/bnxt/bnxt_en/if_bnxt.c +++ b/sys/dev/bnxt/bnxt_en/if_bnxt.c @@ -2674,6 +2674,13 @@ bnxt_attach_pre(if_ctx_t ctx) softc->state_bv = bit_alloc(BNXT_STATE_MAX, M_DEVBUF, M_WAITOK|M_ZERO); + if (BNXT_PF(softc)) { + const char *part_num; + + if (pci_get_vpd_readonly(softc->dev, "PN", &part_num) == 0) + snprintf(softc->board_partno, sizeof(softc->board_partno), "%s", part_num); + } + return (rc); failed: diff --git a/sys/dev/bnxt/bnxt_re/main.c b/sys/dev/bnxt/bnxt_re/main.c index eb21c770ca5f..dc68854157a0 100644 --- a/sys/dev/bnxt/bnxt_re/main.c +++ b/sys/dev/bnxt/bnxt_re/main.c @@ -2031,11 +2031,30 @@ static ssize_t show_hca(struct device *device, struct device_attribute *attr, return scnprintf(buf, PAGE_SIZE, "%s\n", rdev->ibdev.node_desc); } +static ssize_t show_board_id(struct device *device, struct device_attribute *attr, + char *buf) +{ + struct bnxt_re_dev *rdev = to_bnxt_re_dev(device, ibdev.dev); + char buffer[BNXT_VPD_PN_FLD_LEN] = {}; + + if (!rdev->is_virtfn) + memcpy(buffer, rdev->en_dev->board_part_number, + BNXT_VPD_PN_FLD_LEN - 1); + else + scnprintf(buffer, BNXT_VPD_PN_FLD_LEN, + "0x%x-VF", rdev->en_dev->pdev->device); + + return scnprintf(buf, PAGE_SIZE, "%s\n", buffer); +} + static DEVICE_ATTR(hw_rev, 0444, show_rev, NULL); static DEVICE_ATTR(hca_type, 0444, show_hca, NULL); +static DEVICE_ATTR(board_id, 0444, show_board_id, NULL); + static struct device_attribute *bnxt_re_attributes[] = { &dev_attr_hw_rev, - &dev_attr_hca_type + &dev_attr_hca_type, + &dev_attr_board_id }; int ib_register_device_compat(struct bnxt_re_dev *rdev)
