Additionally, fam:6 model:6 stepping 3 never existed in the real world afaict. I used to keep x86info's stepping db pretty up to date, and that only has knowledge of stepping 1 & 2.[*] Modelling qemu on something from the real world might be a better idea than inventing new special cases. > Oh, and the thing has CPUID_EXT2_LM which is also a WTH moment for me. > Paolo, what's going on here? Yeah, this is a mess, there should be no family < 0xf with LM set. Dave [*] It's possible I somehow missed it, or the AMD rev docs never mentioned it for some reason, but it seems unlikely. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
