Ring 1/Ring 2 Runtime support for Pseudo drivers?

NTDEV
1

Hello,

Is there any possibility of adding Runtime support to
Win2k to execute drivers under Ring 1/Ring 2. This
might help in reducing the time to debug atleast the
pseudo drivers which doesn’t talk to hardware.

Does it require substantial changes in the kernel or
might be done by a third party. Also will there be any
takers?

Thanks,
Sajeev

Yes. You will need to call ALL kernel’s functions via the syscall
path, also you will lose direct access to things like
Irp->AssociatedIrp.SystemBuffer.

Interesting… in short, people have to learn one more
way of writing windows drivers
