reading a register/attempting DMA. Now it'll wait for a certain number
of seconds rather than a certain number of times through the loop
before deciding that it's timed out and resetting the hardware. Also,
add more timeout handling, and reset the draw state after resetting the
engine.
instead of ErrorFs for things that are really bad, and put limits on
some loops. Now, sometimes instead of hanging the entire system, we
(mostly-) cleanly drop to console when the card has hung.
- Add monochrome hardware cursor support.
- Try to auto-detect AGP support for DRI on Radeons. And fail. Detect it
properly on R128.
- Set up card for pseudo-DMA if possible. Convert 2D rendering code to
prepare DMA packets only. Use generic code to decode DMA packets to
MMIO if PDMA is unavailable. Add WIP code to support "real" DMA without
DRM support.
- Dispatch pending DMA commands when the server sleeps. Otherwise some
things, such as typing in an xterm, wouldn't show up for a time.
- Fix Radeon Composite acceleration in many ways, and add Rage 128
Composite acceleration. Disable them both due to still-not-understood
issues they have. They fail with In, Out, AtopReverse, and Xor, and
text rendering is strange.
- Add textured XV support for R100 and Rage 128. No brightness/sat
controls, but it does support multiple ports, and cooperates with
Composite.
- Add WIP code for hostdata uploads.
- Many cleanups and fixes.
