Hi,
I've posted this question to the Mellanox support site, but I've found
that it's not terribly responsive. I was hoping someone here would know
the answer to my question, or be able to direct me to someone who does.
I'm reading section 9.2.1 of the ConnectX Family PRM (Posting a Work
Request to a Send Work Queue) and I'm a little confused.
Previous sections mention that the Send Queue is sampled at the WQEBB
boundaries. And ownership is passed from SW to HW via the owner bit in
the Ctrl segment. If that is the case, why does each 64 byte block of
the SQ need to be invalidated initially and as the SQ progresses?
Let's say my WQEBB is 256 bytes. I would think that the HCA would only
sample every 256 bytes for a valid control structure. Why do I need to
maintain 64 byte chunks?
Thanks for the help.
