Note, the i-teams have requested approval by Friday, Apr 23, so unless somebody objects and needs more time, this case will timeout on Friday, April 23. This case clarifies the current hv behavior for the vpci io api, for which versions 1.1 and 1.2 were previously approved but never enabled due to some issues, and creates version 2.0, which requires strict compliance with the interface spec and allows the guest to request mappings with the "relaxed ordering" attribute, which is a performace issue on some platforms. The complete explanation of all this is in the file in the materials directory, which can also be seen here: http://cpubringup.sfbay.sun.com/twiki/bin/view/CSWFirmware/VpciV2dot0 Part of the case deprecates PCI_DMA_SYNC (fast trap 0x80, function number 0xb8, vpci v1.2, which never shipped on any platform), end enables negotiation of v2.0 for io api group 0x100. Requested release binding: - Firmware - Any - OS Components - Minor, Micro, Patch Upon approval, I will update the trap registry and put an updated version of the io-api.txt (with sccs history) with the updates defined by this case in the FWARC Specifications directory. (See section 5 in the case file document). -David From sacadmin Wed Apr 21 00:23:29 2010 Received: from dtmail.sfbay.sun.com (pkg.SFBay.Sun.COM [129.146.90.56]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id o3L7NTa6028422 for ; Wed, 21 Apr 2010 00:23:29 -0700 (PDT) Received: from [192.168.0.9] (noho.SFBay.Sun.COM [10.6.92.101]) by dtmail.sfbay.sun.com (8.14.4+Sun/8.14.4) with ESMTP id o3L7NS5i022304; Wed, 21 Apr 2010 00:23:28 -0700 (PDT) Message-ID: <4BCEA7F1.4020600@oracle.com> Date: Wed, 21 Apr 2010 00:23:29 -0700 From: David Kahn User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.9) Gecko/20100317 Thunderbird/3.0.4 MIME-Version: 1.0 To: fwarc@sac.sfbay.sun.com CC: Tayfun.Kocaoglu@oracle.com, alan.adamson@oracle.com Subject: Re: io-api vpci v2.0 FWARC/2010/137 fast-track, timeout 4/23/2010 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Status: RO Content-Length: 376 On 4/20/2010 11:00 PM, wrote: > Upon approval, I will update the trap registry and put an updated > version of the io-api.txt (with sccs history) with the updates > defined by this case in the FWARC Specifications directory. > (See section 5 in the case file document).

Sorry, that wasn't quite correct. PCI_DMA_SYNC is not, itself, deprecated. The change in arguments that was part of v1.2 is deprecated. Since v1.2 never shipped and the reason for it "disappeared" we can safely deprecate that v1.2 change. Anyway, it's all explained correctly in the case materials. -David From sacadmin Tue Apr 27 17:23:29 2010 Received: from noho.sfbay.sun.com (noho.SFBay.Sun.COM [10.6.92.101]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id o3S0NTdg014696 for ; Tue, 27 Apr 2010 17:23:29 -0700 (PDT) Received: from noho.sfbay.sun.com (localhost [127.0.0.1]) by noho.sfbay.sun.com (8.13.7+Sun/8.13.7) with ESMTP id o3S0NR0Z023690; Tue, 27 Apr 2010 17:23:27 -0700 (PDT) Received: (from dmk@localhost) by noho.sfbay.sun.com (8.13.7+Sun/8.13.7/Submit) id o3S0NRgn023689; Tue, 27 Apr 2010 17:23:27 -0700 (PDT) Date: Tue, 27 Apr 2010 17:23:27 -0700 (PDT) From: David Kahn Message-Id: <201004280023.o3S0NRgn023689@noho.sfbay.sun.com> To: fwarc@sac.sfbay.sun.com Subject: Re: io-api vpci v2.0 FWARC/2010/137 fast-track, timeout 4/23/2010 Cc: Tayfun.Kocaoglu@oracle.com, alan.adamson@oracle.com Status: RO Content-Length: 634 >Note, the i-teams have requested approval by Friday, Apr 23, so >Requested release binding: > > - Firmware - Any > - OS Components - Minor, Micro, Patch This case timed out on and is marked as approved as of Friday April 23. >Upon approval, I will update the trap registry and put an updated >version of the io-api.txt (with sccs history) with the updates >defined by this case in the FWARC Specifications directory. >(See section 5 in the case file document).
