KCS ipmi interface doesnt work

KCS ipmi interface doesnt work

Hi, All,
My server BIOS tries to send ipmi command "self test", but openbmc( I tried Zaius)  doesn't response.

Is this right? Or how can I debug this? Thanks.

Zaius is an OpenPower machine.  OpenPower is using the bt (block
transfer) device on the lpc bus to comunicate with the host for
IPMI and does not use the KCS protocol or the keyboard device.

Someone else can suggest a better platform to copy the
IPMI configuration to use KCS.

Intel platforms are using the KCS interface for BIOS/BMC communication.

Notice there is a known issue about the dbus name, need to convert the dash to underscore

Ipmi-kcs3 needs to change to ipmi_kcs3

kcsbridged -c ipmi_kcs3
kcsbridged -c ipmi_kcs4

Thanks,
