Hi Jean,

As the mask used for smb_en_status doesn't depend on the value of
"aux", this implies that on the Hudson-2, a single bit controls if both
SMBus controllers are enabled. It's not possible to enable one and
disable the other. Is it correct, or is it an overlook?

Good question. This is the current design, not an overlook.

BTW it would be really great if we could have access to the
documentation for these new AMD chipsets. I looked for both Hudson and
FCH at http://developer.amd.com/ but these searches returned nothing. I
could help better if I had access to the documentation / datasheets.

I don't know who is the website maintainer but forwarded your question
to our FCH datasheet maintainer, and he will follow up. I hope that it will
be improved in near future. :-)

BTW, will this patch appear from kernel 3.14-rc1 ?


Thanks,
Shane
