Ah, I first read the commit message as saying this is RISC-V specific,
which I couldn't find in the spec.

I now realise you just mean it's important for RISC-V

Can you provide some details of where this is described? I can't seem to find it

Alistair


System Management BIOS (SMBIOS) Reference Specification 3.7.0 (DSP0134)
https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.7.0.pdf
7.5.2 Processor Information — Processor Family
Table 23 – Processor Information: Processor Family field

200h 512 RISC-V RV32
201h 513 RISC-V RV64
202h 514 RISC-V RV128

While for other architectures values for different CPU generations have 
been defined the values for RISC-V only depend on the bitness.


Best regards

Heinrich





Add a processor-family option for SMBIOS table 4.

The value of processor-family may exceed 255 and therefore must be provided
in the Processor Family 2 field. Set the Processor Family field to 0xFE
which signals that the Processor Family 2 is used.

[PATCH v2 1/4] smbios: add processor-family option

2023-12-29 Thread Heinrich Schuchardt
For RISC-V the SMBIOS standard requires specific values of the processor
family value depending on the bitness of the CPU.

Add a processor-family option for SMBIOS table 4.

The value of processor-family may exceed 255 and therefore must be provided
in the Processor Family 2 field. Set the Processor Family field to 0xFE
which signals that the Processor Family 2 is used.
