May I ask what goal you are trying > to achieve? Well, I wanted to make an "example" app that exercises as many 3d related capability as possible. With the hope that once this is published people with more knowledge of Mesa internals would be tempted to make a real driver. Also, it is possible to access CP fifo via MMIO registers - if I remember this right. That was going to be my second choice, with the preference of connecting to DRM module directly. > > > > 5.

For the > other code, the DRI tree isn't the right target IMHO. No, I meant the code that makes TV-in work. I was incredibly busy this year and did not have time to start porting to 4.4.0 codebase. best Vladimir Dergachev > > > -- > Earthling Michel DÃnzer | Debian (powerpc), X and DRI developer > Libre software enthusiast | http://svcs.affero.net/rm.php?r=daenzer > ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
