Hi!

Yes.. Works nice. :-).

I'm able to program the blitter from the user space XvMC lib, but as expected not the video engine nor the mpeg player.

I've requested info from VIA about this. Let's see what happens.

What approx size of the ringbuffer would the 3d lib need?


Currently the 3D driver has 2 2MB buffers. I think a single 2MB buffer should be big enough.

OK. I've put the buffer in the last 2 of the 32 MB AGP area the DDX allocates. I've also restricted the public AGP map and the AGP memory manager not to include this area, for security reasons. If I understand it correctly, only the kernel should have access to the buffer.


Also, The irq enable IOCTL returns an error with your patch applied. Not before. The via specific IRQ setup routines are never called. Could you have a look into this?
