Rafael and Greg: The following series of emails contains my proposed patches for the runtime PM core, leading up to a general "autosuspend" implementation. This is going to be one of those difficult cross-subsystem things, because the first patch in the series affects sysfs whereas the rest affect PM. (In addition, there are two other patches I'm not going to include here that update USB to take advantage of the new PM facilities. Ultimately there will be changes to the SCSI, block, and IDE layers as well -- they're not written yet.) We can decide on the best plan for merging these later on. For now I would simply like to post them for review and comments. These are not yet necessarily in final form, but I think they are pretty close. They apply on top of 2.6.36-rc5. Alan Stern 1/7: Add sysfs_merge_group() and sysfs_unmerge_group() routines for later use by PM and USB. 2/7: Move the runtime PM accounting routines away from the functions that do the actual work. 3/7: Replace runtime PM boolean arguments with bitflags. 4/7: Merge the synchronous and asynchronous runtime PM routines. 5/7: Regroup the public entry points for runtime PM into three simple functions. 6/7: Add the "no_callbacks" flag. 7/7: Implement autosuspend. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
