writing large blocks of memory in Windbg

WINDBG
1

Hi,
I am trying to write about 256 k of data into memory using ed. It seems to
take a large amount of time ( I have never seen it work it completely). This
data is a precalculated one and I would like to see the behaviour of my
driver when it is so.
Is there another way of writing mass data into memory than ed (or any tips
as such).

thanks

Surely it would be better to add an ioctl to your driver (for debugging
only) to allow a user-mode application to write this data into memory
directly. That way, you’re doing it on the same machine, without
requireing a round-trip across the debugger wire for every word.

what is the maximum size of data that can be written across using !ed (if
there is any?)
