Basic PCIE Switch related questions

Postby Guest » Wed Jun 10, 2020 4:49 pm

I want to know few basic scenarios about PCIE Switch.
1. How is a connect or disconnect even on a downstream port intimated by a Switch to the RC? Is it through MSI/MSI-X or something else?
2. What are all the possible conditions can a Switch send MSI/MSI-X packet to RC?
3. If an Endpoint on a Downstream Port of a multi port Switch is disconnected, do we need to re-enumerate all the other endpoints of the other ports?
4. What happens during Receiver Equalization Phases (1/2/3)? What happens on the PIPE signalling interface? What is PRESET, FS, LS?
5. What Extended Capabilities are to be supported by Switch?
Thanks & Regards,
