What: /sys/bus/dfl/devices/dfl_dev.X/fec_mode |
|
Date: Oct 2020 |
|
KernelVersion: 5.12 |
|
Contact: Xu Yilun <[email protected]> |
|
Description: Read-only. Returns the FEC mode of the 25G links of the |
|
ethernet retimers configured by Nios firmware. "rs" for Reed |
|
Solomon FEC, "kr" for Fire Code FEC, "no" for NO FEC. |
|
"not supported" if the FEC mode setting is not supported, this |
|
happens when the Nios firmware version major < 3, or no link is |
|
configured to 25G. |
|
Format: string |

What: /sys/bus/dfl/devices/dfl_dev.X/retimer_A_mode |
|
Date: Oct 2020 |
|
KernelVersion: 5.12 |
|
Contact: Xu Yilun <[email protected]> |
|
Description: Read-only. Returns the enumeration value of the working mode of |
|
the retimer A configured by the Nios firmware. The value is |
|
read out from shared registers filled by the Nios firmware. Now |
|
the values could be: |
|
|
|
- "0": Reset |
|
- "1": 4x10G |
|
- "2": 4x25G |
|
- "3": 2x25G |
|
- "4": 2x25G+2x10G |
|
- "5": 1x25G |
|
|
|
If the Nios firmware is updated in future to support more |
|
retimer modes, more enumeration value is expected. |
