I'm busy with other things - but hopefully will succeed testing it and pushing it today. As to 2028 (No FMR support) - I need pushed a fix to only disable ZCopy when no FMR facility. I don't have time right now to add support for fast memory registeration when FMR is not available - but Steve said he'll help with implementing it. - Amir On 04/23/2010 05:34 PM, Andrea Gozzelino wrote: > Hi Amir, > > have you any news about bug 2027 and 2028 (SDP)? > > Take care and keep in touch. > Thamk you very much, > Andrea > > > On Apr 21, 2010 02:01 PM, Amir Vadai wrote: > > >> Hi Andrea, >> >> I am preparing the fix right now. >> >> - Amir >> >> On 04/20/2010 04:53 PM, Andrea Gozzelino wrote: >> >>> Hi Amir, >>> >>> have you any news about bugs 2027 "SDP not respecting # SGEs as >>> reported >>> from HW" and 2028 "SDP should support fastreg mrs"? >>> >>> When those bugs will be fixed, I will test the NE020 cards >>> performance >>> with SDP protocol and I will compare SDP and TCP. >>> >>> Keep in touch, >>> >>> Andrea Gozzelino >>> >>> INFN - Laboratori Nazionali di Legnaro (LNL) >>> Viale dell'Universita' 2 >>> I-35020 - Legnaro (PD)- ITALIA >>> Tel: +39 049 8068346 >>> Fax: +39 049 641925 >>> Mail: andrea.gozzelino@lnl.infn.it >>> >>> >>> >>> >>> >>> >>> >>> On Apr 15, 2010 10:38 AM, Amir Vadai wrote: >>> >>> >>> >>>> It should be a simple fix and I plan to do soon - just add yourself >>>> as >>>> CC in bugzilla - that way I won't forget to notify you. >>>> >>>> - amir >>>> >>>> On 04/15/2010 10:07 AM, Andrea Gozzelino wrote: >>>> >>>> >>>>> On Apr 15, 2010 08:24 AM, Amir Vadai wrote: >>>>> >>>>> >>>>> >>>>> >>>>>> I hope to have a fix next week for the first one. >>>>>> >>>>>> Thanks, >>>>>> Amir >>>>>> >>>>>> On 04/14/2010 09:48 PM, Tung, Chien Tin wrote: >>>>>> >>>>>> >>>>>> >>>>>>>> Tung, Chien Tin wrote: >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>>>> One more thing - Please open a bug regarding the num_sge >>>>>>>>>> limitation at: >>>>>>>>>> https://bugs.openfabrics.org/ >>>>>>>>>> >>>>>>>>>> >>>>>>>>>> >>>>>>>>>> >>>>>>>>>> >>>>>>>>> Done, Bug 2027. >>>>>>>>> >>>>>>>>> Chien >>>>>>>>> >>>>>>>>> >>>>>>>>> >>>>>>>>> >>>>>>>>> >>>>>>>> And 2028 opened to request fastreg support. >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>>> >>>>>>> I am open to test fixes for these two bugs. >>>>>>> >>>>>>> Chien >>>>>>> >>>>>>> >>>>>>> >>>>>>> >>>>>>> >>>>>> >>>>>> >>>>>> >>>>> Hi Amir, >>>>> Hi Chien, >>>>> >>>>> I understand that the bug 2027 could be solved next week, so I >>>>> will >>>>> test >>>>> SDP protocol performance on NE020 cards. >>>>> Is it correct? >>>>> If yes, could you point out the code modifies? >>>>> >>>>> Keep in touch and take care. >>>>> Regards, >>>>> Andrea >>>>> >>>>> >>>>> Andrea Gozzelino >>>>> >>>>> INFN - Laboratori Nazionali di Legnaro (LNL) >>>>> Viale dell'Universita' 2 >>>>> I-35020 - Legnaro (PD)- ITALIA >>>>> Tel: +39 049 8068346 >>>>> Fax: +39 049 641925 >>>>> Mail: andrea.gozzelino@lnl.infn.it >>>>> >>>>> >>>>> >>>>> >>>>> >>>> >>>> >>> >>> >>> -- >>> To unsubscribe from this list: send the line "unsubscribe >>> linux-rdma" in >>> the body of a message to majordomo@vger.kernel.org >>> More majordomo info at http://vger.kernel.org/majordomo-info.html >>> >>> >> > > > > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
