Introduction 1.1. Project/Component Working Name: Intel 10GbE PCIE NIC Driver 1.2. Name of Document Author/Supplier: Author: Samuel Tu 1.3 Date of This Document: 22 October, 2007 4. Technical Description This case adds support for Intel 10GbE PCI Express Adapter Driver into ON. The architecture of the Intel 10GbE PCI Express Adapter differs significantly from the Intel 82597EX based PCIX Adapter, which is supported by ixgb. An important new feature of this adapter is I/OAT (I/O Acceleration Technology) from Intel which will be helpful for performance improvement. So we introduce a new driver to support them. Intel has software license agreement with Sun to allow Sun integrate this driver and distribute the software in both source, and binary object code forms. This SLA also grants Sun the right to make modification to the source code and distribute the modified driver in open source and binary forms. The driver supports x86/x64 and SPARC platform. The vendor ID and device ID of the chips supported are: pci8086,10C6 pci8086,10C7 Interface Table +-----------------------------------------------------------------+ | NAME | STABILITY LABEL | DESCRIPTION | +------------------------+-----------------------+----------------+ | Interfaces Exported | |-----------------------------------------------------------------| | ixgbe | Committed | Driver name | |------------------------+-----------------------+----------------| | SUNWixgbe | Committed | Package name | +-----------------------------------------------------------------+ | Interfaces Imported | |-----------------------------------------------------------------| | GLDv3 | Consolidation Private | PSARC/2004/571 | | | | PSARC/2005/396 | +-----------------------------------------------------------------+ 6.

So we introduce a new driver to support > them. let's see. I/O AT is a collection of new capabilities that may involve the NIC, the chipset and/or the CPU. Could you say more about which of these capabilities that this case will be using/supporting? which are expected to actually be present on SPARC, Intel, AMD systems? Will the driver invoke any new kernel interface to query whether the platform specific features are present or not? is this case introducing these interfaces or are they covered elsewhere? Also looking at Intel's docs (and previous presentations), there is a hint to a need for an "optimized TCP/IP stack" in order to benefit from I/O AT. (see for instance http://download.intel.com/technology/comms/perfnet/download/98856.pdf). Is this case introducing changes for the OpenSolaris TCP/IP stack to be able to use I/OAT ? Any new interfaces needed to negotiate such capabs? Last, one comment about the Asynchronous low cost data copy (a.k.a. Intel's QuickData component of the I/O AT), this seems to be a generic enough functionality, with benefits beyond the networking. My suggestion is to consider exposing the interfaces that use it.

AFAIK, the "I/OAT" mentioned is to describe h/w capability. Because this case itself doesn't introduce any interface changes, the interfaces involved to support this feature is out of the scope this case. Below paragraph was trying to explain why a new driver needed and wanted to imply such feature can be supported in the future when framework is ready. Hope this clarification is helpful. Also, please see below embedded answers. -Cecilia Kais Belgaied Wrote: > Cecilia Hu wrote: >> >> The architecture of the Intel 10GbE PCI Express Adapter differs >> significantly from the Intel 82597EX based PCIX Adapter, which is >> supported by ixgb.

Can you explain how this project relates to PSARC 2004/824? That case also aimed to deliver a driver by the name "ixge" for Intel 10Gb Ethernet interfaces. Is this case a duplicate? Does it supersede or obsolete the previous one?

Not an ARC issue, but I hope these agreements are being reviewed by the OpenSolaris team.

This case depends on that framework in order to deliver its support for key performance functionality. This case imports interfaces from that framework.

Given the fact that the case included support for I/O AT features to help performance, and given the observation that other Operating systems needed to change their TCP/IP stack is addition to the driver in order to benefit from I/O AT, can this case be considered complete without the TCP/IP stack changes? can it deliver any performance benefit at all without those changes?

James, Thanks for your time on this case. The hardware are completely different designs here so we'd introduce a separate driver to support it. It's NOT a duplication with PSARC 2004/8247.
