vertex buffer. ELTS are not supported yet (missing functionality in
the DRM). You need at least Savage DRM version 2.1.3, which fixes a
bug that screwed up triangle fans and strips.
Moved the texture normalization stage to savagerender.c.
|
|
Fixed: Use savageEmitChangedRegs instead of savageEmitContiguousRegs for
emitting Savage4.
|
|
* 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.

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).

driver. It uses the new DRM version 2.0.x now, which has just been
committed to DRM CVS.

supported so far.

misplaced in savageDDInitState_s3d, where was overwriting completely
unrelated S3D registers with garbage.

Now, the driver's Viewport routine should call _mesa_ResizeBuffersMESA()
if necessary.
Cleaned up code related to GLframebuffer width/height initialization.
Set initial viewport/scissor params in _mesa_make_current2(), instead of
in the drivers' MakeCurrent functions.

- Don't lock in savageDDUpdateStatte, don't call savageEmitHwStateLocked
- Need to grab the lock for texture uploads now
- New SAVAGE_NEW_CULL bit in new_state to make sure that culling state and
raster_primitive are not examined at the wrong times.

Only available with Xlib driver for now.
Assorted clean-ups related to Draw/ReadBuffer().
Renamed FRONT_LEFT_BIT -> DD_FRONT_LEFT_BIT, etc.

A bit more cosmetics.
Improved state emit on Savage 3D/IX/MX.

which registers changed in all the functions that change the state. Instead
check which registers changed in the end when the hardware state is updated.
Tried to avoid cosmetic (whitespace) changes in this commit.

with modifications to make it work with current Mesa 6.
