Re: [coreboot] SMBIOS table enablement in coreboot

[Mayuri Tendulkar]

We are using coreboot 4.4 only, because when I do dmidecode – t 0, its showing me bios version as 4.4-573.

Still type 17 doesn’t come up.

How we can access DIMM information from HOB?

Hi Mayuri

I have the same question with braswell coreboot that the source code is got from intel.
Intel source code don't implement smbios type 17.
but  you can get dimm information in HOB that is created in FSB image.
If you use coreboot4.4 for your bay trail platform. I think the type 17 is created.

Thank you

Hi David

Thanks for response.

So are there any other settings which enable Type 17 i.e. DDR data information in SMBIOS?

We don’t see this Type 17 information in our table.

Mayuri

Yes, below are settings for our system. As we are using Intel Baytrail, does this SMBIOS manufacturer shd be Intel?

That's up to you. Mainboard manufacturer, along with product name, serial number, and version, are strings which are expected to be assigned by the vendor. You may set these in your mainboard's Kconfig file. The Macbook 2.1 port shows an example of how to do this: https://review.coreboot.org/cgit/coreboot.git/tree/src/mainboard/apple/macbo....

Other SMBIOS tables such as memory info is generated automatically by coreboot. For example, the type 4 table should have details about your processor manufacturer (Intel) as well as information which implies Baytrail (CPU family, model, and stepping).

CONFIG_MAINBOARD_SMBIOS_MANUFACTURER="xxxxx"
# CONFIG_SMBIOS_PROVIDED_BY_MOBO is not set
CONFIG_GENERATE_SMBIOS_TABLES=y
CONFIG_MAINBOARD_SMBIOS_PRODUCT_NAME="yyyy"

Hi Mayuri,
Do you have GENERATE_SMBIOS_TABLES enabled in your config?

Hi
We are using coreboot for our board based on Intel Baytrail 3845.

When we use dmidecode –t to get DDR details, we get empty. It means data is missing in SMBIOS.

Are there any settings in coreboot to enable this?
