Infiniband Adapter with Documentation

Infiniband Adapter with Documentation

[Brandon Falk]

Heya,

I have a compute cluster which uses a completely custom OS (not binary
or source compatible with Linux by any means), and I'm really
interested in Infiniband support. Are there any adapters out there
that have development guides for system level stuff (such as PCI
BAR/MMIO space, etc). I'd ideally implement for the Mellanox
ConnectX-4, but I'm willing to go where the documentation is.

I just want to make a limited driver capable of RDMA writes and reads,
not planning on supporting much more beyond that. How feasible is
that? I've written multiple 1GbE drivers and a 10GbE driver
(specifically for the X540) which was a 8 hour project thanks to good
documentation. Is documentation of this sort available for Infiniband?

I'd be looking for the Infiniband equivalent of this
https://www-ssl.intel.com/content/dam/www/public/us/en/documents/datasheets/ethernet-x540-datasheet.pdf
.

I have looked a lot for publicly-available documentation for
RDMA-capable NICs, but without success.

AFAIK, Mellanox's datasheets (Programmer Reference Manuals - PRMs) are
available to "customers with a design-in portfolio" under an NDA:
https://community.mellanox.com/thread/1052. Can someone with more
experience shed some light on this? For example, if I buy a Mellanox
card, am I eligible for its PRM?
