Hi All,

Now I work with intel-ipmi-oem and want to get smbios blob.
I use intel-ipmi-oem lib and ipmi-whitelist.conf with phosphor-host-ipmid.

I test this by ipmitool like this ipmitool raw 0x30 0x1a and get:
Unable to send RAW command (channel=0x0 netfn=0x30 lun=0x0 cmd=0x1a
rsp=0xc1): Invalid command
 In journalctl:
Oct 11 09:06:43 QV-00002-3a1b4b0da2c0 ipmid[278]: Channel/NetFn/Cmd not
whitelisted

How I can debug  this ?

Are there any examples how to get blob with intel-ipmi-oem ?

If you're going to use MDRv1 protocol then I can share the experience.

We use intel-ipmi-oem and it handles requests like 0x3e:0x20 (for
region status) by calling methods of a D-Bus object, which you should
also be able to query manually following

busctl introspect xyz.openbmc_project.Smbios.MDR_V1 /xyz/openbmc_project/Smbios/MDR_V1

output.

"xyz.openbmc_project.Smbios.MDR_V1" is handled by
https://github.com/Intel-BMC/provingground/tree/master/services/smbios .

Example of requesting status of the first region:

# ipmitool raw 0x3e 0x20 1
 11 01 01 02 00 00 80 cc 0a 91

Why are you using 0x30 0x1a, it seems to be
<Intel General Application>:<Get NIC Info> so completely unrelated?

Hi Paul,
Thanks for your response.

I request to this <Intel General Application>:<Get NIC Info> for test.

Now I have some compile errors this
https://github.com/Intel-BMC/provingground/tree/master/services/smbios
...
In file included from /home/qs/provingground/services/smbios/src/cpu.cpp:17:
/home/qs/provingground/services/smbios/src/cpu.hpp:111:17: error:
‘std::string phosphor::smbios::Cpu::processorSocket(std::string)’ marked
‘override’, but does not override
  111 |     std::string processorSocket(std::string value) override;
...
/home/qs/provingground/services/smbios/src/cpu.cpp: In member function
‘std::string phosphor::smbios::Cpu::processorSocket(std::string)’:
/home/qs/provingground/services/smbios/src/cpu.cpp:38:9: error:
‘processorSocket’ is not a member of
‘sdbusplus::xyz::openbmc_project::Inventory::Item::server::Cpu’
   38 |         processorSocket(value);
...
And other typical errors.

I'll fix them and post my progress.
