4e9e0aff79 We need to call _mesa_load_state_parameters() whenever a fragment program 
is enabled and we've changed any GL state that might be referenced by a
fragment program (such as state.fog.params).  Do this during swrast
validation, not in _swrast_exec_fragment_program().

ecd1743a0c In TEX instructions, use precomputed lambda only if using fragment.texcoord[k] 
to sample texture[k].  Use zero otherwise.  Not foolproof, but a good
compromise.

256c96136c For TEX instructions use lambda=0. When sampling from texture unit K we 
were using the partial derivatives of texcoord[K] but the coordinate used
for texture sampling may be something totally different (and texcoord[K]
might not be a real texture coord at all).  Net result was a bogus LOD is
sometimes used, often resulting in using the smallest mipmap level (a
constant color).
Just use zero for now (undef LAMBDA_ZERO to override).
Plus, some additional debug code.

b14bae8466 Fix bug #8799. 
Properly resize bith the drawable and the readable in mgaUpdateRects.
Eliminate the use of the deprecated GetBufferSize interface.  Bump
driver date.

86a465412d Refactor mgaXMesaSetFrontClipRects and mgaXMesaSetBackClipRects. 
Combine mgaXMesaSetFrontClipRects and mgaXMesaSetBackClipRects into a
single new function called mga_set_cliprects.  This enables a small
refactor in mgaDDDrawBuffer.

5af5260f3c Get DRI drawable from framebuffer object. 
In the software rasterization fallbacks, get the __DRIdrawablePrivate
pointer from the driRenderbuffer that is passed in.  This eliminates
the need for the mesa_drawable pointer in MGA context structure.

This partially fixes bug #8799.  wincopy no longer produces a black
window for the destination window, but it does produce incorrect
results if the destination window is resized.

fd2756006a Move edgeflag into the VERT_ATTRIB_SEVEN slot. This means that our 
NV_vertex_program implementation has slightly incorrect aliasing
behaviour.  I think this is reasonable given the simplification and
the fact that the mainstream ARB_vp continues to have the correct
behaviour.

a23e668d40 Move gl_vertex_program_machine struct out of mtypes.h and put into nvvertexec.h.

toward unifying vertex/fragment program execution.

e998c34647 Rather than always allocating 100 instructions, put instructions into a 
temporary buffer, then copy into a malloc'd array of the correct size.
According to Glean texCombine, we never need more than 21 instructions.

efd95c1084 Program instructions are initialized before parsing so no need to set 
Abs, NegateAbs, CondMask and CondSwizzle fields to defaults here.
CondMask was getting mis-set.  Removing the incorrect assignment improves
fragment program speed by 15%.

b1f176039a Changes for new vbo-building module. 
- Removed all the old immediate, array and display list code.
	- Remove references to the old array_cache module.
	- Added a _tnl_draw_prims() entrypoint.
	- Added a simplified data import facility for converting
non-floating point data as required.

Checkpoint commit - trivial/tri works.

fd12b37dba Checkpoint of new vbo-building code. Currently builds regular arrays 
rather than VBO's - VBOs are easy but need to look closer at the
driver interface.  The trivial/tri demo works.

e9b923182e change some bogus comments regarding the base e exponential function used for fog in vertex programs. 2006-10-25 12:14:26 +00:00
Roland Scheidegger
fc606f7db9 fix (per-vertex) fog when using ARB_vp by incorporating fog factor computation into the vertex program (not yet fixed for swtnl). Simplify (and correct) the VTX_TCL_OUTPUT_VTXFMT handling when using vertex programs, turns out it's solely driven by the needs of the past-vertex stage of the pipeline, this should fix lockups with ill-specified applications using vertex programs (for instance applications enabling fog but not writing to fog coord output will now get (conformant) undefined results instead of lockups). 2006-10-24 22:37:51 +00:00

759facb4d8 Emit cliprects in the userspace driver as required, rather than 
passing them to the kernel.  This works because all drawing commands
in the 965 driver are emitted with the lock held and the batchbuffer
is always flushed prior to releasing the lock.  This allows multiple
cliprects to be dealt with, without replaying entire batchbuffers and
redundantly re-emitting state.
