Yup, agree that this is a key enabler, and that this is a problem we’ve been 
talking about for a while. Looking forward to hear what you’ve been thinking 
about!

Glad to hear y’all will be working together – looking forward to the updates :)

Omar - Carlos is right on. Someone can rush out code to solve a point problem, 
if it's useful to the community, but we've been trying to think about this at a 
higher level. To be fair, we brought this up at an OCP engineering meeting at 
UNH over a year ago. It wasn't even on anyone's radar or priority list until 
the past few weeks. So we didn't feel the urgency to contribute to you open 
community yet.

We'll connect with Rob, Jeff and others ASAP and agree on what can be released 
immediately (and iterated), and what needs more thought and structure put into 
it.

Omar,

I think you are misconstruing the point.  Having a utility to dump standards 
based EEPROM data is done (or should be in the case of ONL) according to SFF 
and MSA standards.  That's not the issue.  The issue is using the 
'non-standard' pages in the EEPROM.  A simple mmap or block read/write may be 
insufficient for some vendors capabilities, thus the progress (or lack there of 
in) is justified.  Based on the doc Pete shared, it looks like they are well 
underway.

For a common utility to use vendor's non-standard pages is not a show stopper 
for Interop testing, but a key enabler going forward.  If a NOS can dump the 
standard pages for SFP and QSFP EEPROM, they are not going to pass the interop 
test.  The purpose of the utility to allow users the ability to query and use 
all of a given vendor's part rather than the lowest common denominator (link 
establishment, link down, query basic EEPROM).

Hi Craig,


At first, I thought there was already working code + specs that you could
contribute to the open given you¹d been working on it for 6 months, but it
sounds like it is at basically a concept phase. Given that, can you also
add OpenNetLinux folks (Rob/Jeff) to the list of parties to understand
what they have so far as they already have experience with it and already
have working code there?

Also, not clear how much we need in addition to this in terms of a big
framework/etcŠ my impression was that OCP testing efforts needs something
asap, and hopefully that can happen sooner than later. If there is a need
for a larger ³architecture² then let¹s present that to the community.

Finally, hope we can iterate on this out in the open and let it take shape
with the community - no need to bake a complete plan/architecture offlineŠ
:) Hopefully you all can get together, figure out some high-level ideas
and then iterate with everyone.

Thanks!

Omar
