The register contents when the HV starts. 2. That %g3 is a pointer to the base address of the mini-md, and the memory pointed to by the mini md is transient. 3. Some (or all?) of the contents of the platform root node in the mini md? I think this needs a bit of work and it's not quite ready for a fast-track timeout yet. a. Which globals? b. Where's the reference to the mini-md format and what's the contents of the mini-md? c. What's the data format of the new variables in the mini md's platform root node and please specify exactly what the platform root node is if it isn't defined in some other case. d. Is the cpuset variable simply a 64-bit integer bit mask? If not, where is the format defined, and how do we represent platforms with more than 64 threads? Please specify all of this for each variable defined by this case or reference other cases that provide these definitions. e. We need to be a little more specific about the longevity of the mini-md pointed to be %g3. What's the requirement on the hv here? That it be copied out prior to initiating any communication with the vbsc, or what? (I think it's an implementation detail that it's put in the fpga/sram, but it's not an implementation detail if that memory is excluded from the available memory.) f. Please specify exactly which interfaces are being imported and which ones are being exported by this case and what their interface taxonomy is. I think you should put this case in "waiting need spec" and come back when you have a better interface document. Finally, I think it's good that you are trying to document this interface. -David From sacadmin Mon Oct 15 15:50:07 2007 Received: from sunmail3mpk.sfbay.sun.com (sunmail3mpk [129.146.11.52]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id l9FMo7BL017123 for ; Mon, 15 Oct 2007 15:50:07 -0700 (PDT) Received: from nwk-avmta-2.sfbay.sun.com (nwk-avmta-2.SFBay.Sun.COM [129.145.155.6]) by sunmail3mpk.sfbay.sun.com (8.13.7+Sun/8.13.7/ENSMAIL,v2.2) with ESMTP id l9FMkgVJ003667 for <@sunmail2sca.sfbay.sun.com:FWARC@sun.com>; Mon, 15 Oct 2007 15:46:46 -0700 (PDT) Received: from pmxchannel-daemon.nwk-avmta-2.sfbay.sun.com by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0JPZ00JGZ5XVVS00@nwk-avmta-2.sfbay.sun.com> for FWARC@sun.com (ORCPT FWARC@sun.com); Mon, 15 Oct 2007 15:46:44 -0700 (PDT) Received: from sca-es-mail-2.sun.com ([192.18.43.133]) by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0JPZ00AF64HWA950@nwk-avmta-2.sfbay.sun.com> for FWARC@sun.com (ORCPT FWARC@sun.com); Mon, 15 Oct 2007 15:15:32 -0700 (PDT) Received: from fe-sfbay-10.sun.com ([192.18.43.129]) by sca-es-mail-2.sun.com (8.13.7+Sun/8.12.9) with ESMTP id l9FMFWiO016218 for ; Mon, 15 Oct 2007 15:15:32 -0700 (PDT) Received: from conversion-daemon.fe-sfbay-10.sun.com by fe-sfbay-10.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) id <0JPY00E01N7HWB00@fe-sfbay-10.sun.com> (original mail from Yanmin.Sun@Sun.COM) for FWARC@sun.com (ORCPT FWARC@sun.com); Mon, 15 Oct 2007 10:15:32 -0700 (PDT) Received: from [129.153.85.54] by fe-sfbay-10.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) with ESMTPSA id <0JPY00FMWQLST490@fe-sfbay-10.sun.com> for FWARC@sun.com (ORCPT FWARC@sun.com); Mon, 15 Oct 2007 10:15:28 -0700 (PDT) Date: Mon, 15 Oct 2007 10:15:28 -0700 From: Yanmin.Sun@sun.com Subject: fasttrack FWARC/2007/593 - Mini MD Sender: Yanmin.Sun@sun.com To: fwarc@sun.com Message-id: <4713A030.7070009@Sun.COM> MIME-version: 1.0 Content-type: text/plain; format=flowed; charset=ISO-8859-1 Content-transfer-encoding: 7BIT X-Accept-Language: en-us, en X-PMX-Version: 5.2.0.264296 User-Agent: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.7) Gecko/20070109 Status: RO Content-Length: 432 I am sponsoring this fast track case for Fred Gotwald.

Can the mini MD instead have a series of fwd arcs (memory-segment?) to nodes that contain and address and size? Steve
