NV03_PGRAPH_NSTATUS and NV03_PGRAPH_NSOURCE.
The prefix NV03 is chosen because nv10reg.h had no versioned prefix,
and the code using these registers does not check card_type.
The PGRAPH init for the various cards will need cleaning up at some point,
a lot of the values written there are per-context state left over from the
all the hardcoding done in the ddx.
It's possible some cards get broken by this commit, let me know.
Tested on: NV5, NV18, NV28, NV35, NV40, NV4E
graphics objects:
- No longer takes flags/dmaobj parameters, requires some major changes
to the ddx to setup the object through the FIFO. This change is
likely to cause breakages on some cards (tested on NV05,NV28,NV35,
NV40 and NV4E).
dma objects:
- now takes a "class" parameter, not really used yet but we may need
it at some point.
- parameters are checked, so clients can't randomly create DMA objects
pointing at whatever they feel like.
misc:
- Added FB_SIZE/AGP_SIZE getparams
- Read PFIFO_INTR in PFIFO irq handler, not PMC_INTR
- Dump PGRAPH trap info on PGRAPH_INTR_NOTIFY if NSOURCE isn't
NOTIFICATION_PENDING.
Hook into nv20 pgraph switching functions (they're identical for nv3x).
Actually call nv30_pgraph_context_init so the ctx_table is allocated.
Thanks to Carlos Martin for the help.
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.
