-
- Working Group Staffing - Teener
-
- temporary recording secretary
-
- Ed Gardner was dragooned into this role.
-
- new Chair
-
- Mike Teener reported that he is overwhelmed by 1394 and other work,
- particularly the combined responsibility of being both technical editor and
- Chair. Jerry Marazas (IBM) has offerred to take over the Chair's
- responsibilities, allowing Mike to devote full time to editting the document.
- The actual formal appointment of Jerry as Chair will depend on the IEEE
- bureaucracy.
-
- Draft Status - Teener
-
- baseline delay
-
- Baseline draft is not ready. The version handed out at the meeting will not
- be given to IEEE for reproduction, because the PMD changes have not been
- incorporated yet. The PMD incorporation should be completed next week and
- will be made available in all the usual places.
- Due to the changes, this version is not yet suitable to advance to baseline
- status.
-
- updates to PMD
-
- The connector doumentation has been updated, with minor changes to wording,
- an additional test specification, a change in the location of the detent, and
- numerous small changes to the drawings to remove ambiguities The electrical
- interface was changed to match the document that Roger Van Brunt brought to
- the December meeting.
-
- updates to Overview
-
- Extensive comments were received from Greg Floryance and Doug Chisholm. To
- accurately report these to reviewers, Mike has included their comments and
- his replies in the front (overview) of this version. Also extensive detail
- has been added explain how the self-ID process works.
- other changes
-
- Link protocol has minor state machine corrections.
-
- Apple Licensing - Zar
-
- Apple intends to comply with the IEEE patent policy for inventions necessary
- to comply with 1394. Other patents useful for 1394 but not necessary to
- comply will be retained by Apple and licensed commercially. A written
- statement to this affect was available (see attached document). More details
- will be provided at the March meeting.
-
- Tom Potyraj expressed surprise at hearing that an Apple patent license would
- be necessary. Ed Gardner (Digital) observed that a Digital patent filing may
- apply to the 1394 fair arbitration scheme; this will not be known until the
- patent issues and the allowed claims are known. This was a repetition of
- statements made to Mike Teener approximately a year ago, although with less
- public discussion. There was substantial discussion of patent licensing and
- IEEE policy, educating those present.
-
- SGS-Thompson Licensing Update - Crowell
-
- Another lawyer reviewed the license terms and added four words: "before
- opening this package".
-
- Backplane Task Group Report - Potyraj
-
- Adopted 10 bit arbitration sequence, four bits priority and six bit
- arbitration number (i.e., node number). The four priority bits allow for
- fourteen priority levels in addition to fair and isochronous.
- Discussed arbitration bit timing in best case / worst case scenarios.
- Previous analysis omitted certain delays (e.g., flip-flop setup times).
- Discussion of optimizing for best case or worst case, with programmability to
- change delays to accomodate other configurations. Voted to adopt worst case
- timing always, without programmability.
-
- Debated if 1394 should specify other than 2 nodes per module for backplanes.
- Voted in favor of specifying a max of 63 nodes per backplane, with no limit
- on the number of nodes per module.
-
- Debated what environmental conditions should be specified for electrical
- parameters. Agreed to specify compliance "over the application temperature
- range".
-
- Action items: Recalculate gap timing with new arbitration bit timing. Ask
- plenary if/how other folks can participate in the sponsor ballot (see below).
- Look into monarch selection for backplanes; backplane folks are convinced
- they do not need a monarch.
-
- Next Meeting: Thursday, April 22, St. Petersburg, FL (with the Bus
- Architecture Standards Committee meetings). Note that the X3T9.2 (SCSI)
- meeting is April 19-20 and the P1394 plenary is April 21, all in St.
- Petersburg.
-
- How to vote on sponsor ballot
-
- To join the balloting body that will vote to approve 1394, call the IEEE
- Standards Department in Piscataway, NJ, at +1-908-562-3805. If you want to
- join the TCMM (Technical Committee on Minicomputers and Microprocessors) and
- get automatic invitations to join any TCMM sponsored balloting body, then
- call the Computer Society office in Washington, DC, at +1-202-371-0101.
-
- Connector Task Group - Hatch
-
- In response to the request to add some sort of connector latching mechanism,
- the connector task group proposed simple jack screws along the sides of the
- connector (i.e., making the narrow dimension fatter). People bitched and
- moaned about jack screws as opposed to a more user friendly latching
- mechanism, but no one raised a "real" objection. The connector group hadn't
- persued other latching mechanism due to limited time and questions about the
- need or market demand for latching connectors. Alternate layouts were
- suggested for the jack screws to allow denser connector packing, including a
- vertical layout (above and below the long axis of the connector) or a
- staggered horizontal layout (one side raised and the other lowered).
- After discussion, there appeared to be concensus that a clean latching
- mechanism (shuttle based or whatever) was a requirement. Also, that the
- latching mechanism needed to be compatible with rows of connectors in a
- bulkhead, allowing the same spacing either with or without latching. There
- was the usual bickering among connector manufacturers over design details and
- whether or not they were proprietary. The connector task group agreed to
- continue investigating non-jack screw latching mechanisms, specifically
- shuttle-type latches.
-
- Ed Gardner asked the connector task group to determine the appropriate
- spacing between connectors in a panel row or bulkhead arrangement, the intent
- that this be included as an informative dimension in the specification. The
- connector task group agreed to determine this dimension.
-
- Jerry Marazas asked if there were any patent issues regarding to connectors
- and specifically latching mechanisms. Connector representatives stated that
- they didn't know of any per se, but that that could not be positively
- determined until after a specific latching mechanism was chosen. This will
- need to be followed up after the connector design is complete.
-
- Molex presented a proposal for an internal device connector based on the
- miniature micro-ribbon connector (1.27 mm pitch, leaf-type contact,
- "Centronics" style). This is a standard connector available in 20-100
- contacts, 30 are proposed for 1394. Discussion of the environment for this
- connector led to statements that its goals are to concentrate on "board to
- board" connections in a blind mating environment. While cable attachments
- might happen, they are outside the design center and need not be consciously
- addressed.
-
- Larry Lamers echoed the need to bring disk oriented connector issues to the
- Small Form Factor committee. He further stated that the connector was small
- enough that some spare contacts should be added, including additional grounds
- to deal with mating skew in cable environments, if "you guys are remotely
- serious about this". Larry observed that achieving the internal connector's
- goals would require that the connector position be specified relative to
- drive mounting holes, which would require Small Form Factor involvement.
- Greg Floryance agreed to be a focal point to collect system vendor
- requirements for the internal connector and its environment, with the intent
- that this be brought to the next Small Form Factor committee meeting in
- March.
-
- Device Connector -Floryance
-
- Greg made an abbreviated pitch at last meeting. Connector task group has
- discussed this, but says they need guidance from users (e.g. system houses).
- Greg complained of receiving very few comments from anyone. There is some
- evidence of internet email being flakey, resulting in some messages not
- getting through. Greg stated that if the lack of public participation
- continued, he would give up and persue a private connector definition.
- power management
-
- Previous strawman had dedicated pins for different voltages. Greg discussed
- adopting ideas from PCMCIA, where power pins are initially 5 volts and later
- negotiated down to 3.3 volts. After some discussion, noone in the room
- supported the idea, instead preferring separate +3.3, +5, and +12 pins as in
- the strawman. There was considerable unproductive discussion of how power
- conserving devices might switch between consuming +5 and +3.3 volt power. The
- end result is that the strawman proposal was left unaltered.
-
- Phy-Link Interface Update Baldwin
-
- A new version of Apple's Link-Phy Interface was distributed. Jim Baldwin said
- some of the state machines need to be updated, but it is otherwise believed
- complete and accurate. There was discussion of incorporating this as an
- informative annex of the 1394 specification, with general concensus that this
- should be done. But this did lead to questions of whether it might be covered
- by or otherwise entail yet more patents. Apple's representatives stated that
- they did not believe this was patentable, and in any case had no intention of
- attempting to patent it.
-
- Cable Configuration Preference (homework report) - Teener / working group
- The maximum number of hops determines the round trip delay, which in term
- affects bus performance. A higher maximum leads to configuration flexibility
- and more robust operation (lower likelihood of violating configuration
- rules), but lower performance. This was discussed at the last meeting, and
- was mostly repeated.
-
- After discussion, there was agreement that all 1394 compliant nodes shall
- implement programmable or configurable timers for hop counts of 2, 4, 8, and
- 16 nodes. The actual delays will be specified in time (microseconds), but
- those will correspond to the specified hop counts using normal configuration
- assumptions (which will be documented in an informative annex). All nodes
- shall power up using the 16 node delay; the actual delay may subsequently be
- programmed by the root node. This passed as a motion 10 in favor, 1 opposed.
- Greg Floryance expressed a need for finer granularity due to concern for the
- performance impact of a (for example) 5 hop system having to use the delay
- for an 8 hop system. Mike Teener requested that people consider this over
- lunch.
-
- Following lunch, Greg Floryance observed that the overhead got worse at
- higher data rates if maximum packet size remained the same. Ed Gardner
- retorted that maximum packet size would scale with data rate, keeping
- overhead roughly the same. Subsequent discussion covered the impact to
- Apple's chip designs and whether that was a relevant issue.
- After discussion, Ed Gardner moved and Jerry Marazas seconded that all 1394
- compliant nodes be required to include a programmable round trip delay
- counter allowing round trip delays to be programmed to any multiple of 81.38
- nsec (8 base rate bit times) between 81.38 nsec (1x) through 5208.33 nsec
- (64x) inclusive, and that all compliant nodes shall default to 5208.33 nsec
- at power up. The motion passed 15-0 (23 people were in the room during the
- vote).
-
- Fair / Urgent and Mixed Speeds - Floryance / Teener
-
- The current definition of urgent arbitration allows sending three urgent
- packets every time a fair packet is sent by some other node. This requires
- that nodes using urgent arbitration be able to see all packets sent by all
- other nodes. But the urgent node may not be able to see packets sent at
- higher data rates (even if it itself supports the higher speeds). We could
- argue that this isn't important; that it need not be "fixed", urgent
- arbitration is best efforts and/or configuration dependent. Or we could
- devise some scheme to fix it. Mike Teener requested that discussion of this
- occur via email or telephone in anticipation of resolution at the next
- meeting.
-
- This led to a rathole concerning the potential abuse of urgent arbitration by
- ill behaved devices. Greg Floryance requested that there be some way to
- manage urgent arbitration, that is, devices would be prohibited from using
- urgent arbitration unless explicitly enabled by some management entity.
- Prototype Status - Teener
-
- A lab demo was provided.
