I've been lurking awaiting to see such a discussion. Alerting the PCI drivers
that their resources have been changed from underneath them by extending the
suspend/resume model, or perhaps (heresy?) adding a new callback entry point
specifically for instructing PCI drivers to re-read their BARs, etc. would be a
step in the right direction to enable this whole re-balancing work; well,
granted root/paging devs bound to PCI devs could be tricky. It seems entirely
natural (to me) that Microsoft would shudder at the amount of work and
verification of all drivers to do this, but the Linux community's attitude
seems to embrace sweeping changes ;-).
