I have never published my work because my approach was rather crude and remote was not very responsive - it used polling. You can get my old patched port here: http://mikhailov.org/files/lirc-0.7.2-cxm-patched-port.tar.gz I never got to create full patch against LIRC though, so use at your own risk. Few months ago I decided to stop fighting windmills and converted FreeBSD MythTV box to Linux, and boy, how much better experience it is! Everything just works out of the box - no patching of cxm driver to bring V4L2 ioctls, MythTV never crashes, tuner appears to get much better picture - I have no idea why. I love FreeBSD a lot, but in multimedia it lags behind Linux considerably. It's pleasure to see that you guys trying to change it to the better. Talking about REAL fix for PVR350 remote: I believe the only good solution to this is to enhance cxm kernel driver to create another device like /dev/cxmr0 (in addition to /dev/cxm0) for remote control, so select() on it could be used by LIRC and avoid polling. This will also make creating LIRC driver extremely simple. In fact, hw_cxm may become simplest driver of all LIRC drivers - almost all heavy lifting will happen in kernel. Actually, such heavy lifting is already done by bktr (and REMOTE_GETKEY ioctl can use it as is), it only needs to do it via device other than tuner device, and should support read() and select(). Good luck! Vadim Mikhailovhome | help
