This patch tidies up a few loose ends left by the preceding patches. It indicates the controller supports remote wakeup whenever the PM capability is present -- which shouldn't cause any harm if the assumption turns out to be wrong. It refuses to suspend the controller if the root hub is still active, and it refuses to resume the root hub if the controller is suspended. It adds checks for a dead controller in several spots, and it adds memory barriers as needed to insure that I/O operations are completed before moving on. Actually I'm not certain the last part is being done correctly. With code like this: outw(..., ...); mb(); udelay(5); do we know for certain that the outw() will complete _before_ the delay begins? If not, how should this be written? Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
