Field Descriptions Scratch Data (Data)-Bits 31-0.
So you get one per socket, first one at PCI_DEV(0,0x18,2) 0x9C
AFAICS this is not MMIO, so it's unusable for locking.
? I thought you were looking for config space. Why does it need to be MMIO?
I did look at the Family 0Fh BKDG. Should I have looked elsewhere?
I'm not an expert. I'd just seen this scratch register recently.
