Question about NVMe MCTP in dbus-sensors

[Heyi Guo]

Hi,

We can see that NVMe sensors in dbus-sensors relies on MCTP to get 
hardware information. It is using libmctp interfaces to initialize MCTP 
and SMBus. However I don't find the code or component who is responsible 
as a bus owner, to discover endpoints, manager EID and update routing 
table. Isn't necessary for a central component to do such things? Will 
there be access conflict if non-NVMe devices (MCTP capable) are also 
connected to the same SMBus？

We also found another implementation from Intel: 
https://github.com/Intel-BMC/pmci. It implements mctpd to provide MCTP 
message transfer interfaces on D-Bus, while PLDM, NVME-MI and others can 
rely on the D-Bus interfaces instead of libmctp. In my opinion it seems 
to be a more mature solution for MCTP and higher PCMI management models. 
Is there any plan to accept such implementations into the mainline?

Thanks,

Heyi
