First let me say that the purpose of this project is to
make the entire stack (with all of the enablement layers)
including the drivers opensourced.
The kernel abstraction layer will be built
around standards based (opengroup.org/icsc) RNIC-PI
interface and which allows the RNIC vendors to opensource
their drivers using that interface. BTW, RNIC-PI
interface is work-in-progress and the first draft
is targeted to be published soon.
Several RNIC adapter vendors, who contribute to the
openRDMA effort, are quite willing to opensource
their drivers through openRDMA project.
BTW, I understood why you got the impression
that the this is for closed source vendor drivers:
Our intention is not to allow the kernel verbs
provider code (kVP) to be private and that was
an error. Thanks for pointing this out
but we'll make this change soon.
