SMBIOS 3.0 support in dmidecode

an invention by jdelvare

On February 12th, 2015, the DMTF released version 3.0.0 of the System Management BIOS Reference Specification. This update isn't just adding enumerated values to existing structures, as previous updates did. It is also introducing a new entry point format which allows for larger tables and structures. Support for this needs to be added to dmidecode. Additionally, reading the entry point and the table from /dev/mem is no longer possible on all systems, so some work is in progress to offer an alternative interface through sysfs. It would be great to finalize this and release a new version of dmidecode that would support both SMBIOS version 3.0 and this new kernel interface.

DMI table conformance checker

a project by jdelvare

The SMBIOS specification includes an informative annex providing conformance guidelines for DMI table implementations. I would like to write a checker tool to verify the conformance of DMI tables, based on this document. Such a tool could be useful for system firmware writers. We already have dmidecode which is able to locate and decode DMI tables. It should be fairly easy to reuse the same core and add an alternative structure parser, which would perform the checks instead of printing the decoded information.

Out-of-the-box SPD support

an invention by jdelvare

In order to see the SPD (detailed memory information) data, the user currently has to manually load the needed kernel driver. Which driver to load depends on the memory type. Depending on the driver user, the devices may even have to be instantiated manually and this is a non-trivial multi-step task. Plus you need to be root to do it. I would like to attempt to automatize all this at least in the most common and simple cases like Intel x86 desktop. The idea would be to figure out the memory type and the I2C address of the SPD EEPROMs based on DMI data. If the DMI data is of good quality then it should be possible to automatically figure out which driver to use and to instantiate the devices at boot time.

Support for BIOS-based error log in dmidecode

a project by jdelvare

Project Description

The DMI table may contain BIOS-based error information. Currently dmidecode is not able to decode it. However an experimental patch was contributed a few years ago, which could be used as a starting point to enable this feature.
