| Description: | |
| The /sys/devices/platform/HISI04Bx:00/chipX/ directory | |
| contains read-only attributes exposing some summarization | |
| information of all HCCS ports under a specified chip. | |
| 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. | |

| 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. | |
