[ewg] GPUDirect Support

[Jagga Soorma]

Hey Guys,

I am trying to enable GPUDirect support in our environment and I have built
OFED release 1.5.2.  I was expecting the following directory to be created
but don't see this directory and the files within that would help me enable
gpudirect:

/sys/module/ib_core/parameters

The parameter file I am looking for is
/sys/module/ib_core/parameters/gpu_direct_enable.  Any ideas as to why the
parameters directory is missing altogether?  Anyone on this list have any
experience with this.

Here is some information about my environment:
