Power saving mode

[Giuliano Pochini]

I have a card which can enter a low power state. It turns
off some components but it leaves the PCI bus interface
active. To bring the card back to life it has to be
reinitialized from scratch. What "D" state is it ?  PCI
power management papers say that already in D1 state
i/o space is disabled. I'm a bit confused... I can't
find any doc about D0.5  :)

Bye.
