After several long months of inactivity, I've restarted work on the luxdvd project (LuxSonor LS200 DVD family decoder chipset kernel driver for Linux). As can be seen from the following log output, the board appears to be initialized and the microcode appears to be loaded:

Now, IOCTLS have to be implemented. Will probably do sound first since that should be much easier than video. Still need to gather more info on the three sound formats (PCM, AC3, MPEG) to do this properly. Probably will tackle PCM first if I can find a DVD with that format, or perhaps find suitable reference samples. Still kinda stumbling in the dark when it comes to these.

Recreation

Yesterday I spent a couple hours backing up all important files (or at least, all the important ones I remembered. Oops.) and re-installed and configured GNU/Linux. Need to upgrade the Kernel to a 2.4-pre version for the new PCI services as the current LuxSonor code expects that. Then, its on to writing the hooks between user and kernel space. Joy.

Tangent

At a recent job fair, Compaq gave out "Linux" license plates. A friend-of-a-friend was lucky enough to get one which he put on the front of his car. A couple weeks later, he got this (~500k).

Someone's not going to be happy.
