I can't tell from that block diagram. I tried to see if 0x61 is part of the AMD-8111 chipset, but it seems that they have removed all downloads from that web page (http://www.amd.com/us/products/embedded/chipsets/Pages/other-embedded-chipset-products.aspx, last 3 links are bad). I would expect 0x61 to be part of the 8111 or possibly 8132 chipset. > --- Randy Dunlap wrote: > >> On Fri, 16 Jul 2010 00:00:36 +0900 (JST) tanaka wrote: >> >>> Dear all. >>> >>> I investigate about NMI kernel messages. >>> Linux kernel read 0x61 address using inb(61h). >>> >>> I search a amd opteron cpu following manuals. >>> but I do not find explanation of 0x61 address. >>> >>> >> > http://support.amd.com/us/psearch/Pages/psearch.aspx?type=2.1&product=2.1.4&contentType=Tech+Doc+Processor&ostype=&keywords=&items=20 >>> >>> Could you teach me a 0x61 address of X86 arch > >> >> Hi, >> >> IO port 0x61 (NMI Status & Control register) is not CPU-specific on >> x86. >> It's more of a platform thing. >> >> Intel describes it in ICH (chipset) specs, e.g., ICH7 spec, >> section 10.7.1.
