Hi Ilya,
We don’t have any video card so no listing in device tree. KCS and IPMB should be working fine.
We use kcs1 and kcs2 only.  Just check if you are using latest kernel and has ipmb driver entry in device tree.

Hi, Vijay!

About KVM:
When I was build OpenBMC, KVM did not work. There was no vhub and video nodes in devicetree file. Is this done on purpose?



Right now I have problem with KCS Bridge, but i fix it with udev rule like this:
KERNEL=="ipmi-kcs3", SYMLINK+="ipmi_kcs3"
And fixing phosphor-ipmi-kcs_git.bb<https://urldefense.proofpoint.com/v2/url?u=http-3A__phosphor-2Dipmi-2Dkcs-5Fgit.bb&d=DwMFaQ&c=5VD0RTtNlTh3ycd41b3MUw&r=v9MU0Ki9pWnTXCWwjHPVgpnCR80vXkkcrIaqU7USl5g&m=xJd9l55w4_jXkxlHu57P3jeoPNHXgCEvjF2D9ByPU_g&s=CjSN51iKoIK-hHREyPitTu0Mq4-LvFeh-eMO9hJ_5MQ&e=>



Right now i have a problem with starting ipmb service.





Do you have such problems too?
Or is it my fault?



Thanks,


Ilya

Hi!

>I have tried to touch Tiogapass (by Wiwyn).
Good.
>I have added the devices for KVM. And it works.
What are you trying for KVM here?
>Now i want to get information about hardware (for example CPU and DIMM imformation, like model, clocks, etc.). How i can get it? Only from IPMI stack (like KCS)?
Yes it can be accesses from IPMI stack via ipmi tools, you can run ipmitool from BMC console itself. And there is a file in /etc/appData.json which stores all of these data.
