7b51aa54be Added GL_POLYGON primitive. Single primitive between glBegin()/glEnd() now works. 2005-01-06 00:10:11 +00:00

3e4d4aca77 * Fixed handling of scissors 
* Only set scissor regs directly if drmMinor < 1
* Don't set texaddr to 0 when a texture unit is disabled. That would trigger
  the tightened texture state check in the DRM if the texaddr and texdesc
  registers were not emitted atomically.

699fc6baf9 Make the format of the fastpaths cleaner at the expense of a little 
performance.

Add fastpaths for some more common vertex formats.

dd9666bc1d Give attributes with zero-stride a count of 1 to make it easier 
to avoid transforming the same attribute multiple times.

Don't light a single normal multiple times in light_fast_rgba*

e3fe80a60f Bring VIA driver up-to-date with regard to drm_*_t changes and remove 
the xf86drmVIA.[ch] files.

Bring in the IRQ handler and Ring buffer code, but ring buffer is disabled
as it is with the Xserver. It certainly locks up the CLE266.

6b185aaedf Port code from r200 that implements color blending. Seems to work. 
This can be tested with lesson19 from NeHe.
This has also shown that the alpha code does not work - we pick up a red tint
for transparent pixels somewhere.

638faa92fc Major code restructuring: 
* move proven code into the r300_state.c
  * update ClearBuffer to cope with more dynamic state
  * cleanup !

b6ab7a1bf1 Change to use the t_vertex.c mechanisms for building vertices, 
including Felix's ptex code.

Re-enable some assembly for performance.

f72e4424d9 Use the GLX 1.3 pbuffer/fbconfig functions in preference to the SGIX ones. 
Added more functions to pbutil.[ch] to better isolate API differences.

e3748eb19b Added support for floating point depth buffers on Savage4-based 
hardware. By also reversing the depth range this can compensate the loss
of accuracy of far objects caused by the projective transformation.
Software fallbacks work but are slightly slower since floats in a custom
(non IEEE) format have to be encoded and decoded. I havn't done anything
about polygon offsets yet. There doesn't seem to be an easy way do get
it right except making the offset unit as big as the lowest resolution
of depth values. For now float depth is disabled by default but can be
enabled through driconf (though I have seen only positive effects so
far).

25faa2d56e Turns out I left flat primitives in vertex buffer mode. Switch them back to immediate which works correctly.. 2005-01-03 06:53:38 +00:00

63473a8e76 Enable code to compute other constants that were used by R200 code. 
Add fprintf to print these constants.
Correct t->size computation, so it works now.

9a04b25c60 Get textures to work with NeHe lesson06. 
The code is still disabled since we are displaying random image data instead of actual texture and because I had to put a sleep(1) in lesson06 drawing loop to prevent lockups.

7a231da442 Improved the performance of software fallbacks by not waiting for idle 
in every single span function. Instead flush and wait in the
SpanRenderStart hook and in wrappers around _swrast_Copy/Draw/ReadPixels.
Misc. cleanups in savagespan.c while I'm there.

1067ce0cea Removed all direct hardware access (MMIO, BCI) from the Savage DRI 
driver. It uses the new DRM version 2.0.x now, which has just been
committed to DRM CVS.

e443d1ec47 Qualify the magic 20B0 register as SE_VTE_CNTL similar to R200. Looks like disabling Z offset and scaling displays gears properly, not sure why. Perhaps the meaning of the bits has changed ? 
Cleanup code a bit.
