sensor-detect and non-compliant SMSC Super I/Os

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All,

I looked through a lot of SMSC datasheets the last couple of days with
the goal to improve sensor-detect to correctly identify more SMSC
Super I/Os. I noticed that some of the chips don't conform to the ISA
PNP standard with the device ID register living at a different address
(0x0d instead of 0x20). In order to correctly identify those chips, a
somewhat ugly (and totally SMSC specific) hack would be necessary.
Something like reading from both addresses and then using the value
from 0x0d for some of the SMSC chips.

I wonder how much value this adds given that none of these Super IOs
have HW monitoring capabilities? The only benefit I can see is that
the chip is correctly identified and we can flag it as not being a
sensor and thus users won't bug us for adding support.

Any thoughts, comments, ideas?

Thanks
