Looking on the libibverbs - XRC instance
(git://git.openfabrics.org/ofed_1_3/libibverbs.git) and re-reading your
email, my understanding is that the way you went was
1. add a new field at the end of struct ibv_qp_init_attr
2. add bunch of new XRC verbs packed in struct ibv_xrc_ops
3. both create_qp & create_xrc_rcv_qp get ibv_qp_init_attr, the latter
looks on the xrc field

ULP section of the policy file doesn't have separate qos-matching-rule
and separate qos-level. Each line in this section internally generates
matching rule, and links it to one of the pre-generated simple qos levels
that has only SL.
Do I want to explain it to the user? No. That's the whole point of the ULP
section - the user is not aware of the full policy file syntax and semantics.
However, the user does know that OSM is enforcing qos according to path queries,
and the single message that I ...

I still need to create a bunch of QPs for this so I have to convey that
information to mlx4. We can get rid of the align parameter and use
another creation flag to let mlx4 know that we need the QPs aligned to
the size of required number of QPs.
We also need to let mlx4 know which QP is used as a default QP -- the
one QP that receives all rx packets that did not map to any of the other
QPs. I thought of doing this through modify QP by putting something like
this

mlx4: enable discarding/passing multicast loopback packets by FW/HW.
When attaching a QP to a multicast group, checks if mcast
loopback packets should be blocked (receives it as a parameter).
If so, it sets the mcast loopback block bit to 1.
When querying a QP (which is mlx4_ib_qp) using ib_qp_query,
the field create_flags of the struct ib_qp_init_attr that is given as
a parameter, will now be set with the flags that were used when
this QP was created.

The blocking is done by the HCA if possible.
This patch creates an improvement of up to 39% in bandwidth when
seding mcast packets with IPoIB.
There is also an improvment of 12% in cpu usage.

I was thinking about applications which create and destroy HCA
Looks to me like using __GFP_ZERO is the cleanest approach. I like
less clear_highpage() since it uses kmap_atomic() which could fail.

I would expect all the other costs of mapping pages into/out of the ICM
to be large enough that the cost of zeroing a page is not too big a
deal. But if there is anyone who cares we can always make this
__GFP_ZERO flag conditional on FW version I guess.
