After the meeting ended today, Ralph made a suggestion regarding writes with
a stream ID: If you think that it might be useful to set deadlines on those
commands, it would be simplest to find a way to add a stream ID to WRITE
FPDMA QUEUED, rather than defining a new subcommand under SEND FPDMA QUEUED.
The problem with the latter is that I have a pending SATA-IO proposal to
obsolete the ICC field from SEND (and RECEIVE) FPDMA QUEUED. That's because
the ability to send an arbitrary command with a deadline is a huge can of
worms. The proposal to obsolete will probably be voted on in Monday's
So the question is whether you might have a use case for writes with stream
IDs *and* command deadlines. Let me know if you'd like to talk about this.
Thanks very much,
