Public bug reported: SRU Justification:
[Impact] Currently, the VPD info stored in the EEPROM does not include a Rev ID. This field is incremented when a PN goes through minor HW changes. Sometimes, SW needs to differentiate the two versions of the card. Hence, this field should be supported in the EEPROM MFG partition. [Fix] EC (Engineering Changes) field is used to denote the HW Revision of a PN. Add it to the EEPROM MFG and provide a sysfs entry to access the same via mlx-bootctl. [Test Case] This field is typically programmed at the manufacturing step using the bfcfg tool which uses the write mechanism in the driver and then the MFG partition is locked. Reading the "rev" sysfs will show the current value. [Regression Potential] Can be considered minimum. ** Affects: linux-bluefield (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1948436 Title: Add RevID field to VPD info in EEPROM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-bluefield/+bug/1948436/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
