-/* NVidia uses context objects to drive drawing operations.
-
- Context objects can be selected into 8 subchannels in the FIFO,
- and then used via DMA command buffers.
-
- A context object is referenced by a user defined handle (CARD32). The HW
- looks up graphics objects in a hash table in the instance RAM.
-
- An entry in the hash table consists of 2 CARD32. The first CARD32 contains
- the handle, the second one a bitfield, that contains the address of the
- object in instance RAM.
-
- The format of the second CARD32 seems to be:
-
- NV4 to NV30:
-
- 15: 0 instance_addr >> 4
- 17:16 engine (here uses 1 = graphics)
- 28:24 channel id (here uses 0)

- NV40:
-
- 15: 0 instance_addr >> 4 (maybe 19-0)
- 21:20 engine (here uses 1 = graphics)
- I'm unsure about the other bits, but using 0 seems to work.
