Dave: I want to modify the bus_suspend and bus_resume routines in ohci-hub.c. The idea is to have versions that can operate entirely in interrupt context.
Normally of course this would be impossible. But if you know that no ports are enabled (or even connected) and none have been for the last second or so, then it should be possible to move directly between the OPER and SUSPEND states with no delays. Will this work? Is it more or less obvious which portions of the suspend and resume routines can be skipped under these circumstances? Will any of the known controller quirks pose a problem? In short, can you offer any advice about the best way to do it? Alan Stern ------------------------------------------------------------------------- Take Surveys. Earn Cash.
