Support for Supermicro X7DBU (Winbond W83627HF/F/HG/G & Winbond W83793G) #6
Comments

A good example of why I rely on vendor information is in doc/board-technical.md for the X7SBL series, where there are two Winbond/Nuvoton chips on the board, but only one is used for hardware monitoring. Talking to the wrong chip could very likely cause system instability. Other times, there are multiple chips used for monitoring (due to large numbers of sensors/fans/etc. that exceed capabilities of a single chip), such as in doc/board-technical.md for the X6DVA series. As you can see, every board varies. What would be helpful is:
It should be noted that the X7DBU is officially EoL'd, per Supermicro's website, and as doc/board-technical.md states, I do not know what their retention policies are on documentation for EoL'd boards. In other words: they may come back and say "sorry we don't have this info due to EoL", in which case I cannot add support for this board (again: I don't take risks, I only rely on vendor information -- stability is important). Let me know if you want me to proceed, and I can start conversations with Supermicro. |

I am aware of the multiple Winbond/Nuvoton; I have provided some of that information as well as links to manuals/datasheets. I am more than willing to help in any way that I can. I do hae a remote networked PDU if the server needs to be rebooted and I have an IPMI card coming that should be here next week. |

It is up to you whether or not you would like to take this on as well. If you run into problems with Supermicro, I may be able to get additional information for you. I used to work for a company who used these boards in their products and have designed a large number of custom solutions and interfaces specifically for these boards. |

Great! I've put in a request to Supermicro. They usually take anywhere from 5 to 10 business days to respond to these type of requests. If I don't get a response within 2 weeks I'll send another. Historically they've been very forthcoming with all the necessary details, though this is the first time I've asked for details on an EoL'd product. Cross your fingers! I forgot one additional item: in the case that they are able to provide said information, I'll also need from you photo(s) of the BIOS screen depicting voltages, fan RPMs, and temperatures of the system where the testing will be done from. I need this to ensure that the labels in bsdhwmon match that of the BIOS (and for general validation of data). Often the MB manual omits these, or describes them inaccurately (e.g. copy-pasted from another model). Likewise, data from IPMI also can't be used for this purpose as it varies per system, IPMI F/W revision, etc.; sometimes they choose to label the sensors simply by "sensor index number" rather than actual function. You can either Email me the photos at jdc@koitsu.org or put them somewhere public (ex. imgur, Dropbox, your own web server, etc.) and provide links here. Thanks! |

Response from Support below. Supermicro is no longer providing technical information for boards that are EoL'd. This is different than how things were several years ago (I was able to ask for information from EoL'd boards on several occasions). Therefore, I cannot add support for the Supermicro X7DBU to bsdhwmon. Your only option would be to get IPMI modules, use whatever tools there are for IPMI (maybe It should also be noted here that on most newer (2013-present) boards, Supermicro has been pushing IPMI quite hard, and TMK no longer provide open documentation for sensor info, instead insisting you use IPMI. This, if the above is true, in effect means bsdhwmon is a project I should probably retire permanently. Sad news. |

I would love support for my Supermicro X7DBU (Super IO: Winbond W83627HF/F/HG/G, Hardware Monitor: Winbond W83793G). I don't have much useful information yet but I'm working on it and I'm willing to provide as much information as advised.
