How/where can I put low-level driver specific suspend/resume code, for PATA or SATA or usb-storage or ieee1394 or SCSI? What is the linkage (chain, pointers, whatever) thru the SCSI stack to each driver's "methods"? Or do those not exist yet?
I will try to post a more concrete followup to my earlier comment about involvement of lower levels, notably ieee1394, at the end of the week. So far I have to say about ieee1394 that - "internal power management" i.e. suspend/resume of the local 1394 host adapters seems not to fully work yet according to sparse reports from users (I did not test it myself under Linux 2.6 yet), - "external power management" i.e. management of power states of attached 1394 nodes is not implemented yet. I hope to implement bus manager contention (a prerequisite for bus-wide power management) in late November or in December. -- Stefan Richter -=====-=-=-= =-=- ==-=- http://arcgraph.de/sr/ - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
