Thank you, It is too helpful!
1) What is the interface over which the Intel x86 CPU sends data to the BMC? KCS or something?
2) I see /var/lib/smbios but don't see /var/lib/smbios/smbios2 in my system. It will be created when the file is received?
3) When the file arrives from the CPU to the BMC, Can I see the information in webui? Do I have to create any configuration files in entity-manager or phosphor-inventory-manager to do this?
4) Besides the CPU and DIMM information, How can I see the information of the chassis and board? I think the only way to do this is FRU? I mean, this information is kept in any EEPROM as binary in the production process of boards. If I think wrong, Is there any way to see the information of the chassis or board?
Regards.

cpuinfo is additional daemon, that actually do nothing with smbios, but
it can get some CPU-related information by using PECI interface. For
about couple of years PECI wasn't supported by upstream OpenBMC, the
implementation was only in Intel's fork.
I don't know actual situation, but I guess you just miss some libraries
for PECI support.
Anyway, you don't need this at this stage.

Yes, smbiosmdrv2 daemon reads SMBIOS information from the file
/var/lib/smbios/smbios2 and you have to somehow deliver it to the BMC
filesystem.

Not sure. I think I saw somewhere in the Internet example of delivering
it using phosphor-ipmi-blobs.

Well, it just parse SMBIOS tables from binary file and expose extracted
information to dbus for other daemons use.
