SMBIOS 3.0 support in dmidecode
an invention by jdelvare
Updated 2 months ago. 2 hacker ♥️.

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.

Looking for mad skills in:

      Roy Franz's patches have been reviewed, tested and committed. This lets dmidecode make use of the upcoming sysfs interface to DMI tables.

      I have just committed the dmidecode patches that implement support for the SMBIOS 3.0.0 specification. So the user-space side of the project is mostly completed, although a few cleanups and improvements are still possible.

      I committed a few more patches yesterday and this morning. There's one issue left that I'm aware of (reading SMBIOS 3.0 64-table from a dump file), I'll look into it.
