Hello, I have my work on the nv vpe video decoder in a functional state. In case you didn't know this decoder accelerates mpeg2 video at the idct/mc level. I have verified that it works on nv40 hardware. I believe it works on nv30 hardware (and maybe some earlier hardware), but I cannot verify since I have none. I will reply with patches against the kernel, drm, ddx and mesa for

Hi guys, I'd like to start a new thread about explicit fence synchronization. This time with a Nouveau twist. :-) First, let me define what I understand by implicit/explicit sync: Implicit synchronization * Fences are attached to buffers * Kernel manages fences automatically based on buffer read/write access Explicit synchronization * Fences are passed around independently * Kernel takes
