Hi, just wanted to update you I did some stupid mistake when I did the
UEFI setup test (that's why I could not boot my Win10).
I suggest we will abandon this patch, and try to keep going on the QEMU
VMBus patchset.
And perhaps submit a very basic patch to SeaBIOS and EDK2 which just
enable SCONTROL.
Does that sound like a good plan to you?
Thanks,
-- Jon.
