[ofw] RE: Porting OFA stack to WDK

[Leonid Keller]

It's a port from Linux. In the first revision it won't support MSI-X.

	Hi Leonid,

	 

	Is the new ConnectX driver a port from Linux or is it a
ground-up Windows driver?  Will it support MSI-X?

	The new ConnectX driver is being developed in WDF environment
and requires WDK tools for its build.

	 

	While trying to build OFA stack in WDK environment i've come
across a __ptr64 problem.

	This attribute causes the WDK compiler crash in checked x86
environment.

	Instead of searching some workaround, i'm going to perform the
following "drastic" solution:

	    - remove __ptr64 attribute from all the functions of the
stack;

	    - remove __ptr64 attribute from all the structures except
the Ioctl ones;

	    - use PtrToPtr64 function while the assignment of __ptr64
Ioctl fields (only in user space);

	    - remove unnecessary castings, related to __ptr64 attriubute
all over the code, if any;

	 

	The changes wrt ioctls will be committed separately to
facilitate the code review.

	 

	Any comments/suggestions/objections ?
