[ewg] Mellanox: ConnectX-3VPI Driver Problem

[Hector Abrach]

Pavan,

Thank you, I've contacted Mellanox via email and they replied they cannot 
dedicate a resource so they moved it up to "Support Admin" for further 
review. We should have an NDA, I'm guessing it's a robot answering, not 
sure.

With respect to my second question:
Yes, It  is connected to Mellanox switch (MIS5022Q). 
I have tested without a switch and says the port is "1: Down". 
I've noticed that if OpenSM is not up the port remains in INIT if plugged 
in to a switch. 
When OpenSM is run under Linux the port goes to the "4: Active" state 
after OpenSM moves to the Master state. I'm currently trying to track down 
where OpenSM fails. My current theory is that it is somehow in the driver: 
core/mad.c and/or OpenSM osm_sm_mad_ctrl.c file. I seem to fail with qp0 
mads outstanding.

We actually, have the MTHCA driver working and I know openSM works for 
that one but we have a new requirement to support the ConnectX QDR 
cards...

Thank you for your help!!

Hector Abrach

Hector,
The Programmers Reference Manual is distributed by Mellanox under NDA. So 
you should contact them for the manual.
For your second question, is the port connected. Is it connected directly 
to another HCA directly or to a switch ?
Thanks,
Pavan

Hello, 

I'm hoping one of you can help me. I'm porting the follwoing driver to 
QNX: 
ConnectX-3VPI 
MCX353-QCB 
Rev A1-A2 
MT_1060110018 

I have a couple questions: 
1. Where can I get the programmer's reference manual for the driver? Can 
any of you provide it for me? 

2. I get the driver to initialize and run all the way to OpenSM. However, 
the port state is stuck in 2:INIT. 
/sys/class/infiniband/mlx4_0/ports/1/state 
Do any of you would happen to know why this is or how to fix it? 

I know this is a mailing list for OpenSM under Linux but any pointers to 
the right people and/or help would be extremely appreciated! 
Thank you in advanced!!
