Hi Shravan,

Could you, please, explain what TRIO PCIe host controller?
What is TRIO, is it some internal name or it's some standard terminology?
If it's internal, please, explain for what it stands for.

Same for TRIO instances. Are there some host side PCI instances?
What are the purpose of them?

Could you, please, also explain the system configuration?
