Re: [ewg] [PATCH] IB/core: Add support for Receive Core Affinity
+int ib_create_qp_range(struct ib_pd *pd, struct ib_qp_init_attr *qp_init_attr, + int nqps, int align, struct ib_qp *list[]) It just seems wrong to me to require the caller to specify the alignment restrictions. Isn't this HCA specific? I agree with you about this, but since my previous posts on the issue did not receive too much attention, I did not want to change my implementation before the issue has been discussed. Is IPoIB really going to know whether or not the QP numbers returned by this call are aligned or not? What if I call ib_create_qp_range() with nqps=3 and align=0? I am not sure I understand your argument here: in this case you create 3 consecutive QPs with no other restrictions on the number of of the first. Also, in ib_verbs.h, struct ib_qp_attr now has a struct rca_attr field. I don't see why the struct rca_attr field is needed for ib_modify_qp(). It seems to me that this information should be stored as part of the QP info when creating the N QPs. Why should the verbs caller need to know about this? The values are determined by the HCA when the QPs are created. I totally agree with you here too and I also sent an email about that some time ago. Again, I want to trigger a discussion to close on the API before re-implementing. I hope to get more opinions and then re-work the patch. ___ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg

[ewg] ofed-1.4 beta
Tziporet, I request that we make sure the following is in before we release beta: - NFSRDMA fastreg patches _and_ NFSRDMA working at least on 2.6.27-rc1. Currently it doesn't install correctly. Also we're waiting for the fastreg patch series from Tom Tucker which should be ready this week. - RDS iWARP bcopy. RDS doesn't currently build in the ofed_2_6_27 branch, and there are a set of patches that apparently never got delivered to Vlad. These should be ready this week as well. I'm asking that we hold off spinning Beta until these are ready. I don't see the point of a beta release if all the anchor functionality isn't in. And from an iWARP perspective, the above two are anchor items. Thanks, Steve. ___ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
