This is not very helpful for the application trying to use the device. Maybe we should zap the device when channels are routed through audio instead of dripping requests?Yes, I have thought about that as well, but it can cause other problems. I have modified the fftest tool from: http://www.koders.com/c/fidF60D5962FCA8B937A6D0947AA81AE95A8C58FB36.aspx for my needs. It opens the /dev/input/eventX, and it will keep it open as long as it is running. It is OK for me, since the twl6040-vibra goes to low power mode when we do not have effects running. I can imagine, that real world application will do the same, and that might cause some problems, if I try to zap the device. Can we zap a device, while it is open? How application will handle that event?
The application will get an error on read or write, like -ENODEV, and will hopefully "drop off". -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
