Nb: this should more or less be considered as an RFC. One thing I already know I need/want to add is a timer callback to make sure we don't get stuck keys due to missing a release event signal. The main area of contention though is over how the keyboard/mouse device is set up. Currently, if you have three raw rc-core IR receivers in your system, you get three separate keyboard/mouse event devices, stored inside rc_dev->raw->mce_kbd->idev. I *think* this is the right way to do this, but one could argue that the decoder should just have a single input_dev within the decoder itself, which is used to feed along signals from any raw IR device. The other question is whether or not this module should be loaded by default when rc-core is initialized. The current implementation means this is loaded, and input devices are set up for every raw IR device, and I doubt the vast majority of people with raw IR receivers actually have this keyboard. -- Jarod Wilson ja...@wilsonet.com -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
