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
|
|
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.
