Ask for sample code to read value from DIMM by SMBUS (Intel® Xeon® D-1627)

[DerekWang]

Hello,

I am developing in linux kernel space and would like to read register value from DDR.
From schematics there is a DDR SMBUS linked to DDR(DIMM). Could you share some linux driver sample code to read the value from DDR by this DDR_SMBUS?
Thank you.

P.S . The smbus I mean is DDR_SCL and DDR_SDA.

Hi Sergio S,

I posted this question on the website you mentioned, but somehow it was moved to Processors website.

I just posted again on embedded server website:
