Hi York,
For the general pcie devices, it will not bring delay, because the RC access these devices can get the link up state correctly, usually, if the slot have the device, return the L0 state, if the slot have not device, return DETECT state, but for a few device, the initial phase it may be polling state(this issue is feedback from customer, we have not this device), After a period of time, the device resume the L0 state, so for this type of device, we need wait a moment, and about the 1 ms delay, It is estimate value, in other words, if this type device resume the L0 state within the 1ms, we consider that it is link up.
Joakim,
Do you accept this reasoning? Can you test on your hardware?
Guys,
I don't think we agreed on this patch. We either continue to discuss, or I will have to drop this set.
