LIRC merges two different things, basic IR driver support and application scripting for non-IR aware apps. Application scripting for unaware apps is always going to happen in user space and it will always need to be manually configured. But scripting should be optional. I'm looking at the driver half and I'd like to explore how zero config support can be built for IR aware apps. Of course we don't have any IR aware apps today because no kernel IR event types have been defined yet. It is better to simply make the apps IR aware and have them process IR events from evdev (in other words forget about the configs code it was a poor man's scripting scheme). For mouse/keyboard support something parallel to USB HID is needed. A couple of common device profiles would be mapped to keyboard/mouse events by default. That should support 90% of users. The other 10% can use a set keys IOCTL to change the mappings. A couple of use cases: insert MSMCE IR device kernel automatically loads all drivers IR events appear in evdev as vendor/device/command triplets apt-get mythtv set universal remote to xmit DVR commands everything just works set universal remote to xmit device A commands device A commands mapped to keyboard/mouse movements everything just works For these default cases you just have to read enough docs to know what device to set your universal remote to. The scenario I'd like to achieve install TV app install audio app install home automation app use multi-function remote to control in parallel with zero config other than setting three devices into the remote. -- Jon Smirl jonsmirl@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
