Description

This repo contains utilities to transfer SMBIOS tables from Host to BMC over IPMI BLOB protocol.

Two implementations are available:

• transfer SMBIOS tables from the UEFI firmware (DXE_DRIVER)
• transfer SMBIOS tables from the OS

BMC requirements

BMC firmware should be based on the openbmc distribution.

You need to add smbios-mdr and phosphor-ipmi-blobs packages to the image.

Besides that you'll need to append the smbios-mdr recipe (recipes-phosphor/smbios/smbios-mdr_git.bbappend) with the following content:

PACKAGECONFIG:append = " smbios-ipmi-blob"

PACKAGECONFIG:remove = " cpuinfo"

Results

After the successful transfer of SMBIOS tables you can check out the objects created by the xyz.openbmc_project.Smbios.MDR_V2 service:

Currently smbios-mdr parses only these types of SMBIOS tables (specification):

• BIOS Information (Type 0)
• System Information (Type 1)
• Processor Information (Type 4)
• System Slots (Type 9)
• Memory Device (Type 17)

Here is an example how webui-vue can display the CPU information:

And here is an example of DIMM information display:

If you want to display PCI devices as well, you should probably check the IBM fork of webui-vue.
