k8m890 id and 'P4VM800pro' description fix
To enable this device for DRI we need to figure out its video engine AGP command
stream capabilities, and also how the 3D engine behaves, and adjusting the
command verifier accordingly so that we don't create a security hole.
From what I understand, the device is a "Unichrome pro group A" when it comes to
video, but has a completely new directX 9 compatible 3D engine. The question is
whether this 3D engine is backwards compatible with what we have today.
So, let's get XvMC running first and then check whether we can use the current
Device numbers are added now,
but 3D and command DMA are disabled since we currently
have no implementation for the new 3D engine.
