Introduction 1.1. Project/Component Working Name: Addition to NIU "phy-type" property values 1.2. Name of Document Author/Supplier: Eric Blanchard 1.3. Date of This Document: 11/05/08 1.4. Name of Major Document Customer(s)/Consumer(s): 1.4.1. The PAC or CPT you expect to review your project: NSN PAC 1.4.2. The ARC(s) you expect to review your project: FWARC 1.4.3.

Responsible Engineer: Eric.Blanchard@sun.com 1.5.3. Interest List: tenaya-sw@sun.com 2. Project Summary 2.1. Project Description: Tenaya is a N2 based rackmount server. Tenaya uses a new ethernet controller that takes the SerDes output of the N2 processor as input and exports 1GB copper ethernet. It exports solely 1GB speed over the copper Ethernet. This case updates FWARC/2006/566 and FWARC/2007/288 to define an additional "phy-type" property value for 1G Copper Phy. 2.2. Risks and Assumptions: If this property value is not defined, NIU driver(nxge) do not understand tenaya configuration and will attempt to initialize the PHY(and fail). 3. Business Summary 3.1. Problem Area: Without this property, nxge driver doesn't know how to initialize the physical layer on Tenaya. 3.2. Market/Requester: 3.3. Business Justification: 3.4. Competitive Analysis: 3.5. Opportunity Window/Exposure: 3.6. How will you know when you are done?: When the OS driver initialize according to the "phy-type" defined. 4. Technical Description: 4.1. Details: To initialize the internal SerDes for data communication over xaui a new property values for "phy-type" is defined. The current set of property values are listed in FWARC/2007/288. The additional "phy-type" value for 1G Copper Phy is defined below. "phy-type" Type: Prop-encoded-string Contents: Sun private property to indicate the type of the physical layer Value: "gsdc" for 1G Copper 4.2. Bug/RFE Number(s): TBD 4.3. In Scope: Section 4.1 4.4.

I don't think using the "hot-swappable-phy" property should be used in an on board device. My next question is, if we want to have the driver probe the device id, and consequentially the device phy-type, using MDIO is it ok to exclude or have incorrect phy-type properties? I think we still need to define a new phy-type value or expand the definition of one of the existing ones.

I think the term "ethernet controller" used in this sentence is mis-leading,

Tenaya uses a new ethernet controller that takes the SerDes output of

You should say "ethernet transceiver" instead.

While doing this I also noticed the niu spec is missing some changes that were added by other cases. My latest spec includes all of the missing changes that I found. I'm summarizing key points of an off-line discussion so it gets archived in the mail section of the case and so other people can provide input. Its been requested that we move away from niu and neptune drivers that rely on phy-type. Part of the reason to do this is the phy-type is unnecessary information in the md. The type of phy that is being used can be inferred by querying the part number of phy device. Resistance to adding this new phy-type value to the niu spec comes from the opinion that phy-type should be degraded, therefore we shouldn't be adding new values. Even with the following resistance, the software team developing the new driver is still pursuing the addition of the new phy-type value. The reasons are the current spec'ed interface for the niu still has the phy-type listed as a required property, and the new phy-type value requested is an accurate description of a phy interface that is not described in the current spec. Removing the drivers dependency of phy-type values can be done, but it requires making a change to the current driver that requires a bunch of regression testing. The new hardware being added is part of a platform project that has an accelerated schedule. Trying to degrade the reliance on phy-type will cause extra effort to be done on a project that already has a tight schedule. The software team doesn't disagree that removing the dependency on phy-type is a good thing and should be done. We just don't think this platform, an N2 platform who's solaris development needs to be finished before the end of the month, should be the platform to pioneer these new changes. If I haven't captured everything, or if I got something wrong, please correct me! Thanks, -Eric
