illumos gate

SMBIOS 3.3 added a few additional features. The most notable of which include:

• A new type, 'Processor Additional Information' with a detailed RISC-V subsection
• Extended clock speeds for memory devices
• Additional definitions for PCIe Gen 4 and high bandwidth memory (HBM)

As part of this, I also went and extended the test suite to cover this and cleaned up a few parts of the smbios_processor_t to be more in line with how we're handling extensions to structure members when both old values and new values fit.

To test this I manually constructed a RISC-V table and dumped it with the smbios command:

ID    SIZE TYPE
1     121  SMB_TYPE_PROCESSOR_INFO (type 44) (Processor Additional Information)

  Processor Handle: 1
  Processor Type: 7 (64-bit RISC-V (RV64))
  RISC-V Additional Processor Information:

I also ran through the updated test suite which covers validation of these new tables and extensions:

$ dmake install && LD_PRELOAD_32=/ws/rm/smbios/usr/src/lib/libsmbios/i386/libsmbios.so.1 ./smbios
