Hi,
What is the IRQL to use DbgPrint() ? Nothing is said in the DDK
documentation.
When I call it at DISPATCH_LEVEL I get “Pageable code called at IRQL 2”
The C line is the following:
Extension=(PDEVICE_EXTENSION)DeviceObject->DeviceExtension;
DbgPrint(“***** %ws: Connect event received\n”,Extension->DosName.Buffer);
and DosName is allocated in a NonPagedPool:
Extension->DosName.Buffer = ExAllocatePool(NonPagedPool, BuuferLength);
wchar or wide string operations requires passive level. Otherwise dispatch
is OK. And IIRC this is clearly statuated somewhere in DDK .

" IIRC … somewhere" means not an obvious location (hidden).
I wish the msdn search engine could handle queries like all high-tech
equipment in hollwood productions:
User types ( or dictates): ‘Show DDK-Docs where IQRL of DbgPrint is explained’
some beeps later … only one page of Information appears that has
exactly the information the user wanted ( or “Access denied” flashes).
“If it jams, force it. If it breaks, it needed replacing anyway.”

Thanks for your answers. I must have an old documentation file and I should
have searched deeper before posting.
It’s indeed written in the online documentation at msdn.com

“IIRC somewhere” can be a very meaningufull location. I couldnt remember a
full URL and I had no mood to open DDK
help to point user at. How about the “DbgPrint” reference itslf ? Or for
that matter, reiterated in references of KdPrint,
DbgPrintEx, KdPrintEx . Is this location obivious enough ?

Just read your DDK help carefully.

O really now, don’t be silly. The display would pound it’s way out one
character at a time at about 80 characters per second all the while sounding
like a teletype. All this is happening while you “virtually” navigate
through some kind of a Picasso maze of colors and what looks like IC’s on
circuit boards.
Hollywood couldn’t find its ass in a bucket of bits if it were sitting on
it.
