Hi Andrey,
I tried your patches on my 2P XGMI platform. The baco can work at most time, and randomly got following error:
[ 1701.542298] amdgpu: [powerplay] Failed to send message 0x25, response 0x0
This error usually means some sync issue exist for xgmi baco case. Feel free to debug your patches on my XGMI platform.
Regards,
Ma Le

Hey Ma, attached a solution - it's just compiled as I still can't make my XGMI setup work (with bridge connected only one device is visible to the system while the other is not). Please try it on your system if you have a chance.

AFAIK it's enough for even single one node in the hive to to fail the enter the BACO state on time to fail the entire hive reset procedure, no ?
[Le]: Yeah, agree that. I've been thinking that make all nodes entering baco simultaneously can reduce the possibility of node failure to enter/exit BACO risk. For example, in an XGMI hive with 8 nodes, the total time interval of 8 nodes enter/exit BACO on 8 CPUs is less than the interval that 8 nodes enter BACO serially and exit BACO serially depending on one CPU with yield capability. This interval is usually strict for BACO feature itself. Anyway, we need more looping test later on any method we will choose.
Any way - I see our discussion blocks your entire patch set - I think you can go ahead and commit yours way (I think you got an RB from Hawking) and I will look then and see if I can implement my method and if it works will just revert your patch.
[Le]: OK, fine.
Andrey
