Board Info Area Format Mfg Date/Time Rollover

Defined by the IPMI FRU Storage Information Specification. Last updated March 2015.

Board Info Area Format has a 3-byte Mfg Date/Time field.
Defined as the number of minutes from 0:00 hrs 1/1/1996.
Rolls over Nov 24th, 2027.

Option 1: OCP NIC leaves the Mfg Date/Time field as-is and allows the value to roll over with a start year ambiguity (1996, 2027, 2058, etc). Possibly following the OpenBMC format: https://gerrit.openbmc.org/c/openbmc/entity-manager/+/87782

Option 2: OCP NIC cards may start using the value of 00_00_00h (“unspecified”) going forward and is required to use 00_00_00h after Nov 24th, 2027.

Option 3: OCP NIC amends the 0xC0 Base OEM Record with a four byte manufacturing date field that starts from 0:00 hrs Jan 1st, 1996.

Option 4: OCP NIC amends the 0xC0 Base OEM Record with a four byte manufacturing date field that starts from 0:00 hrs Nov 24th, 2027.

Board Info Area Format Mfg Date/Time Rollover

Option 5: Implement a DMTF FRU (DSP0220) format in “hybrid” mode. Enables a gradual transition to the DMTF FRU. Backwards compatible.

High Level Changes:

Add a new DMTF OEM Record (0xC0, IANA 0xB41A00) containing a four-byte offset to the new DMTF General FRU Record File position.

BMCs that don’t understand the DMTF OEM Record will skip/ignore the new data.

Option 2 would also be implemented (zero out the mfg date/time field) and, at minimum, includes a new structure with a 13-byte Manufacture Date Field.

Card vendors may populate additional field types (such as the Manufacturer, Part Number, Serial Number) as defined in DSP0257.
Field Types with IPMI equivalents shall have the same data replicated in the DMTF FRU section.

Pros:

Maintains backwards compatibility with existing FRU format.
Minimal effort for NIC vendors.

Existing OCP NIC 3.0 IPMI OEM Records continue to be used as-is
Can co-exist with the IPMI FRU format and I2C EEPROMs.

Baseboard vendors may already support DSP0220 FRU formats.

Cons:

DMTF needs tools/validators/minor specification clarifications.
Misbehaved BMCs need to be examined.
