This question is not directly related to this patch, but given that
this is a copy-paste from the qib driver I'll go ahead and take it
anyway. How does qib (and rvt now) do memory key invalidation? I didn't
see any reference to IB_WR_LOCAL_INV anywhere in the qib driver...
What am I missing?
ping?
In short, it doesn't look like qib or hfi1 support this.
Oh, I'm surprised to learn that. At least I see that
qib is not exposing IB_DEVICE_MEM_MGT_EXTENSIONS. But whats
the point in doing something with a IB_WR_REG_MR at all?
Given that this is not supported anyway, why does this patch
exist?
That doesn't mean it can't be added to rdmavt as a future enhancement
though if there is a need.
Well, given that we're trying to consolidate on post send registration
interface it's kind of a must I'd say.
Are you asking because soft-roce will need it?
I was asking in general, but in specific soft-roce as a consumer will
need to support that yes.
