* Pulled in some registers from nv10reg.h. Needed for context switching.
* Filled in nv30 graphics context (based on nv40_graph.c).
* Figure out nv30 context table, set up on context creation. Allows the cards automatic switching to work.
This is enough to get grctx switching going on my NV40 and C51 after
the binary driver has initialised the card first.
Bumping the drm patchlevel because the ddx needs some modifications to
have NV4x work at all with these changes.
- Do important card init in firstopen
- Give each channel it's own cmdbuf dma object
- Move RAMHT config state to the same place as RAMRO/RAMFC
- Make sure instance mem for objects is *after* RAM{FC,HT,RO}
On X init, PFIFO and PGRAPH are reset to defaults. This causes the GPU to
loose the configuration done by the drm. Perhaps a CARD_INIT ioctl a proper
solution to having this problem again in the future..
Added preliminary support for context switches (triggers the interrupts, but hangs after the switch ; something's not quite right yet).
Removed the PFIFO_REINIT ioctl. I hope it's that a good idea...
Requires the upcoming commit to the DDX.
