Add new DDR4 DDIMM keyword ENTIRE_SPD_WITHOUT_EFD

2019-09-27T22:29:55+00:00

With the DDR4 DDIMM SPD there are really two parts. There is the 640 bytes of information you typically see in a DIMM's SPD and then there are 2 KB - 640 bytes of EFD (extensible function descriptors) to give vendors space to add customized data. In many cases we want the ENTIRE_SPD (including the EFD area) but in other cases we want to save some time/space and only read in the first 640 bytes. This new keyword will give us that flexibility.

Clean up some comments and refactor how we determine new cache entry

2019-06-05T21:39:35+00:00

While code was added to handle detecting new OCMB parts a new check was added to make sure an entry was newly added to cache to make it so we didnt do new part validation on entries that had not been cached yet. This commit removes what was added and leverages existing information we had earlier on in the caching algorith. Also in this commit a few minor comments were addressed related to tracing and doxygen comments.

Add cache/hardware comparison functions for SPD classes of VPD content

2019-05-31T13:51:28+00:00

This commit adds necessary support for ensuring the eeprom cache is in sync with hardware for EEPROM_CONTENT_TYPE DDIMM and ISDIMM. Support for IBM_MVPD and IBM_FRUVPD will be added in a later commmit.

Refactor keyword support for various DIMM types

2019-05-29T20:52:24+00:00

The existing keyword logic didn't use bitmasking when searching for the correct keyword entry. This commit refactors the code to allow for bitmasking and changing the NA module specific keyword to mean that no keyword was found for the given target rather than its previous ambiguous meaning that could be confused with the ALL module specific keyword.

Add keyword support for OCMB SPD reads

2019-05-09T15:42:22+00:00

Currently the only supported keyword was ENTIRE_SPD for OCMB chips. This commit adds support for all of the common keywords (modSpec NA and DDIMM) for DDRx DIMMs and new keywords for OCMB_MODULE_PART_NUMBER and OCMB_MODULE_SERIAL_NUMBER.

Add keywords for part and serial number for DDIMM

2019-05-07T14:58:34+00:00

Adds the PART_NUMBER and SERIAL_NUMBER keywords to spdDDR4.H for DDIMM modules. This way OCMBs don't need to read the ENTIRE_SPD and then index to the correct spot.

Stop overwriting OCMB vpd info in standalone and handle DDIMM modules

2019-04-03T11:26:25+00:00

This commit removes some lines that were overwriting the OCMB's eeproms with what we thought was "good" VPD. Simics itself now has a better copy so we will use theirs. When consuming their VPD however we found that Hostboot was missing support for the DDIMM type modules. This commit also update the spd driver to handle this new type of memory module.

Force VPD IO through HW (Axone) ,add plat function to get OCMB VPD

2019-03-08T03:59:14+00:00

This commit follows up on previous work that pulled in the code that can find the correct EFD given a SPD blob of data which has the DDR SPD and the EFD for the DDIMM. This commit adds ocmb_spd.C which provides a DeviceFW::SPD read interface for OCBM targets, and hooks is up to the platform implementation of the FAPI interface platGetVPD for OCMB target. Also this commit forces all VPD IO in Axone to go through HW, which will actually read from the new EEPROM cache in pnor.
