Subject: RDMA/CM and multiple QPs
Date: Sat, 5 Sep 2015 23:45:50 -0700 [thread overview]
Message-ID: <20150906064550.GA30683@infradead.org> (raw)
Hi All,
right now RDMA/CM works on a QP basis, but seems very awakward if you
want multiple QPs as part of a single logical device, which will be
useful for a lot of modern protocols. For example we will need to check
in the CM handler that we're not getting a different ib_device if we
want to apply the device limit in any sort of global scope, and it's
generally very hard to get a struct ib_device that can be used as
a driver model parent.
Is there any interest in trying to add an API to the CM to do a single
address resolution and allocate multiple QPs with these checks in
place?
