BF16 support in SDE

Hello,

while I can see CPUID to report VP2INTERSECT support (with -tgl, albeit not with -future), I didn't manage to find what option (if any) to use to have BF16 emulation enabled. Could you advise please?

Thanks, Jan

Please use the -cpx (the cooper lake CPU knob) for getting the BF16 instructions emulation.

Thanks much. Is there a table somewhere mapping features to code names / command line options? Is there a reason -future doesn't enable both BF16 and VP2INTERSECT?
