Yes, in the register, it is shifted by 3 bytes > Then we just need C code :-) That is another story... Here is the python script, I have tested it on my SN25p / opteron 165 I attached the output from a run under legacy BIOS: $ AMDK8MemMap.py -i > output.txt with a $ lspci -xxx -s 0:0:18.1 > lspci.txt for reference Could someone double check I did not misinterpreted the doc in the decoding of the registers. I would be interested in having the output of the tool and the lspci, like above, from something more interesting, like a Tyan 2 or 4 processors motherboard. I'm also interested in --test output. Try --help to have the list of available options. I did not use the "Fam 0Fh" 32559.pdf documentation, because I only have an opteron 939 to test on. But after a quick glance, it all looks the same, so it should work as-is. I'd also like comments, and any ideas for further improvements. If this is useful, it is: Signed-off-by: Vincent Legoll <[EMAIL PROTECTED]> and could go somewhere in the utils directory... -- Vincent Legoll
