You say above "we post *up to* 2 work requests", unless you wish to
change that to "we always post at least 2 work requests per queue
entry", Jason is right, your frequency of signaling needs to be X/2
regardless of your CQ size, you need the signaling to control the queue
depth tracking.
If you would like to spread things out farther between signaling, then
you can modify your send routine to only increment the send counter for
actual send requests, ignoring registration WQEs and invalidate WQES,
and then signal every X/2 sends.
Yea, you're right, and not only I got it wrong, I even contradicted my
own suggestion that was exactly what you and Jason suggested (where is
the nearest rat-hole...)
So I suggested to signal every X/2 and Marta reported SQ overflows for
high queue-dpeth. Marta, at what queue-depth have you seen this?
