[Freeipmi-devel] Supermicro OEM PSU power readings

[Kilian Cavalotti]

HI there,

I'm aware of the Supermicro get-power-supply-status and
get-pmbus-power-supply-status oem commands, but I was wondering if
there would also be possible to add support to get power readings out
of the PSUs.

Supermicro has this tool, IPMICFG
(https://www.supermicro.com/solutions/SMS_IPMI.cfm,
ftp://ftp.supermicro.com/utility/IPMICFG/) that allows this:

# ./ipmicfg-linux.x86_64 -pminfo

It seems to use IPMICTL_RECEIVE_MSG ioctls under the hood, so it
probably just sends raw IPMI commands.

Do you think there would be ways to add support in freeipmi to get
more information about PMBus PSUs on Supermicro machines?

Thanks,
