--- Comment #12 from Mikolaj Zalewski mikolaj.zalewski@gmail.com 2008-03-15 13:41:50 --- I'd expect that the wProcessorLevel should be the same as the "cpu family" line in /proc/cpuinfo. For Pentium 4 with the current code it isn't so it would be good to check it (especially that for my Athlon 64 that has also a cpu family of 15 the wProcessorLevel should be 15 so the current code produces a wrong result). Of course it would be also nice to test it on more architectures (I've just checked that on a Core 2 it's the same).
If you test it on a Sempron you should also tell us if this Sempron is a cut-down version of Athlon XP or Athlon 64 (or provide also the /proc/cpuinfo from Linux).
