I found the following in target-i386/cpu.c

    case 0x80000006:
        /* cache info (L2 cache) */
        *eax = 0;
        *ebx = 0x42004200;
        *ecx = 0x02008140;
        *edx = 0;
        break;

>From the AMD cpuid book it look like the L3 settings are not defined (edx).

Eduardo: A user I know want to be able to set the size of the guest L3 cache.
I am ok to write a patch to do so.

Do you have some recommandations regarding the other fields of the edx register 
?
What would be an acceptable user interface to set this ?

Best regards

Benoît
