Hey, I'd actually like some thoughts on the power stuff in the p4 power tree. I want to remove my cruft to just mess with _PSx since the power resource code is much more mature and just use that from the PCI drivers. For that to work correctly however, we will need to perhaps do a pass over the ACPI tree early on (before child PCI bus devices are attached I think) that registers all the producers and consumers. We also might want to fix the register functions to use _PSC if it is available to determine the current power state and then add code to power consumers on before we probe/attach them. Note that with the current power resource code, this would only call _PS0 if it really needed to be called. -- John Baldwin <jhb_at_FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/Received on Fri Dec 05 2003 - 11:24:46 UTC
