Simple WPP Question

Hi,
Can you have multiple drivers trace using the same GUID?

Thanks,

Oh yeah…I used WPP in my port driver (export driver) and I have 3-4
miniports linked to the port driver. They do use the same ctl_guid in the
port driver. WPP works great for me except the thing I complained 2 days ago
regarding logger kicked in too late.

Yes they can. One interesting quirk is that you cannot separate the
different instances of the same GUID apart, ie only receiving logging
from one of the drivers using the same GUID. If that is an issue, you
might want to consider one GUID per driver.
