The X in 'chipX' indicates the Xth chip on platform. There are following attributes in this directory: ================= ==== ========================================= all_linked: (RO) if all enabled ports on this chip are linked (bool). linked_full_lane: (RO) if all linked ports on this chip are full lane (bool). crc_err_cnt: (RO) total CRC err count for all ports on this chip. ================= ==== ========================================= What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/all_linked What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/linked_full_lane What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/crc_err_cnt Date: November 2023 KernelVersion: 6.6 Contact: Huisong Li <lihuisong@huawei.com> Description: The /sys/devices/platform/HISI04Bx:00/chipX/dieY/ directory contains read-only attributes exposing some summarization information of all HCCS ports under a specified die. The Y in 'dieY' indicates the hardware id of the die on chip who has chip id X. There are following attributes in this directory: ================= ==== ========================================= all_linked: (RO) if all enabled ports on this die are linked (bool). linked_full_lane: (RO) if all linked ports on this die are full lane (bool). crc_err_cnt: (RO) total CRC err count for all ports on this die. ================= ==== ========================================= What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/hccsN/type What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/hccsN/lane_mode What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/hccsN/enable What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/hccsN/cur_lane_num What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/hccsN/link_fsm What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/hccsN/lane_mask What: /sys/devices/platform/HISI04Bx:00/chipX/dieY/hccsN/crc_err_cnt Date: November 2023 KernelVersion: 6.6 Contact: Huisong Li <lihuisong@huawei.com> Description: The /sys/devices/platform/HISI04Bx/chipX/dieX/hccsN/ directory contains read-only attributes exposing information about a HCCS port. The N value in 'hccsN' indicates this port id. The X in 'chipX' indicates the ID of the chip to which the HCCS port belongs. For example, X ranges from to 'n - 1' if the chip number on platform is n. The Y in 'dieY' indicates the hardware id of the die to which the hccs port belongs. Note: type, lane_mode and enable are fixed attributes on running platform. The HCCS port have the following attributes: ============= ==== ============================================= type: (RO) port type (string), e.g. HCCS-v1 -> H32 lane_mode: (RO) the lane mode of this port (string), e.g. x8 enable: (RO) indicate if this port is enabled (bool). cur_lane_num: (RO) current lane number of this port. link_fsm: (RO) link finite state machine of this port. lane_mask: (RO) current lane mask of this port, every bit indicates a lane. crc_err_cnt: (RO) CRC err count on this port. ============= ==== ============================================= |
