Hi, I was recently working on a project which adds support for DVB-T, DVB-C, analog TV and FM Radio to Linux [1] The actual driver consists of a kernel bridge which acts as a databridge to userland for the USB endpoints, and the main configuration which is done by a daemon in userland which runs as root and submits the control codes to the i2c components as well as to the usb bridge using raw USB commands (usbdevfs). There's a userspace library available which intercepts the Linux video4linux2 and linux DVB calls and forwards them through a unix domain socket to the daemon which has access to the raw USB control interface. (the library can run as normal unprivileged user and forwards the data to the privileged user who runs the daemon).
The main question for opensolaris is, is there any interest in such a framework? The USB Endpoints will deliver either a valid MPEG-TS (for DVB-T or DVB-C) or raw YUY2 frames for analog TV and/or raw PCM for radio/analog TV The configuration part was entirely implemented in userland, so what would be expected by opensolaris would be: 1.) a userland USB Control Message interface to the kernel for a privileged user 2.) some nodes which just pipe the USB data from the endpoints to userland this system might also be adoptable for PCI devices. The userland framework is supposed to intercept the native Linux DVB or V4L2 calls either by using LD_PRELOAD or by implementing an available user library directly into the target application best regards, Markus [1] http://mcentral.de/wiki/index.php5/Terratec_HTC_XS?SL
