Questions regarding OpenMPI over SRIO Documentation

Hi,

I'm trying to get OpenMPI working over SRIO, and got some questions while reading this documentation:

1. In the "Device Tree Modification" part, I noticed that I need to enable UIO and install the UIO module, the former one is easy, but I cannot find this "uio_module_drv.ko" file. I guess I can build it by modifying the Linux .config file, but failed a couple times. So how can I build/get this file?

2. Also it says to make RIONET loadable as a module, but then it never mentioned that RIONET module... is it relevant?

Thanks,

Shang
