Re: Hot Plug Compliant Silicon

[Henry Gong <hgong@cisco.com>]

Brad,

I have same question. PCI hot plug does not look like a real hot plug.
User has to take care the hot plug process through software. If you hot
plug your card like you do on USB, you may damage the card instantly.
Besides, isolation logic is on the mother board. Compare with
CompactPCI, where isolation logic is on the card.

Please read Tom Shanley's "PCI System Architecture, 4th Ed", page
456. It clearly indicates that "PCI add-in cards designed to the PCI
spec
requires no changes in order to be Hot-Pluggable." However, if you do
implement CompactPCI isolation logic on your 2.2 PCI card, you need to
claim it in corresponding configuration register for new capability.
