Randall, Amancio, Multimedia's I was wondering why we do not have the bt848 driver in the GENERIC kernel. Why do we have to build a new kernel before we can watch TV with FXTV? At first I thought it was because the 864k of RAM the driver allocates. You may not want the Generic Kernel allocating this space. But as FXTV supports the DGA Direct Video mode (DMA transfer from bt848->video card directly) there is no need for a frame buffer in all situations. FXTV can work without it. (It runs faster in DGA mode anyway) Video Capture, e.g. vic, frame_capture for a webcam etc, requires it. We could have a bktr0 in the GENERIC kernel which does not allocate memory for a frame buffer. FXTV users can then boot up and watch TV right away. Video Capture users - well they currently have to build a kernel anyway. Questions for this are... 1.How many FreeBSD users actually use the GENERIC kernel and do not recompile a personalised kernel? Of those using GENERIC kernel, is it really that they have no idea how to make a kernel. Or just no need to personalise it as it detects all their hardware. 2.Would Joe Public use his bt848 purely for FXTV (direct video mode). In which case, getting something in the GENERIC kernel would really help Joe Public. He can watch TV without having to know about kernel options and things. He would also save 864k of memory of memory. 3.What sound card support would a Generic Kernel need. Just enough to initialise the mixer and volume? Thoughts, comments, questions?
