For the BMC connector patch, you know if there is a register setting
I can check to see if a BMC is present or not ?
I think you can use VGA CRD0[7] whose definition is as below:
DRAM Initial Selection (see note 1)
0: VBIOS Initial the DRAM
1: SOC Firmware Initial the DRAM
If CRD0[7] is 1, there is BMC.
Thank you. That seems very helpful.
Thank a lot, I will run some tests, and add this check in my v6.
Unfortunately, on my testing server (which has BMC, and I'm using it)
the bit(7) of CRD0 is set to 0.
Here is the complete register read:
AST read[d0] 0x41
So I will keep the always enabled BMC virtual connector.
