Everything now goes through the draw_vbuf handler, the same as
regular drivers.

Split into component pieces, stitch together at runtime using function
pointers. Make it possible to utilize the existing fastpaths as image-level
filters for generic mip-filtering routines.
Remove special case for rectangle filtering, as it can now be handled by
the 2d path.
As most of the mesa demo texturing was already covered by fast paths, its
harder to find examples of speedups, but tunnel gets a boost as mip-nearest
filtering is now able to access the img_2d_linear_wrap_POT functions
for sampling within a mipmap level.

These do similar jobs but with largely disjoint code. Will want
to evolve them separately going forward.

|
Consolidate the read-modify-write color combining code from
the blend, colormask and output stages.
|
|
First attempt
|

|
|
No performance gain yet, but the code is a bit cleaner.

Render results are only visible when the render cache is flushed.
softpipe_is_texture_referenced must reflect that or transfers to/from the
textures bound in the framebuffer won't be proceeded of the necessary
flush, causing transfer data to be outdated/clobbered.
This fixes conform drawpix test with softpipe.

This reverts commit 5d75124db480b37977c353511b4e228905b7cc95.
This fixed unclipped polygons, but broke clipped polygons.
A better fix from the mesa 7.5 branch will be merged next...
|
|
Use the first vertex, not the last.
|
|
Drivers can just keep track of whether they are within a query
by monitoring the begin/end query callbacks. The flag adds no
information beyond that.
Only softpipe was examining this flag -- it has been fixed up
and retested with demos/arbocclude.

Be more consistant with 'draw' module.
|
|
uint64 is not (so?) standard, and often redefined by third parties,
causing name clashes.
|
|
Need to disable/bypass lambda calculation since derivatives of texcoords
are meaningless for adjacent vertices.

softpipe.
We want to make it env variable, or even better, autodetect as the feature makes
softpipe run slower on a single CPU.
|
|
Configured for 2 cores.
|
|
We were indexing sp_constants[i] outside the loop so i was 2.
Replace i with PIPE_SHADER_VERTEX.
Also, replace magic '2' with PIPE_SHADER_TYPES in a few places.

|
The struct is still there though until all winsys layers are updated

The later follows the naming scheme of other limits.
Keep the old definition until all possible usage is updated.
|

|
|
These are convenience fields. Otherwise, we have to check cbuf[0] or zsbuf
in various places.
|
|
Bind all the samplers/textures at once rather than piecemeal.
This is easier for drivers to understand.
|
|
For hardware without native polygon stipple. Create a 32x32 alpha texture
that encodes the stipple pattern. Modify the user's fragment program to
sample the texture (with gl_FragCoord) and kill the fragment according to
the texel value.
Temporarily enabled in softpipe driver, replacing the sp_quad_stipple.c step.
|
|
This fixes at least one instance of dereferencing an invalid texture pointer.

Update the Makefiles and includes for the new paths.
Note that there hasn't been no separation of the Makefiles yet, and make is
jumping all over the place. That will be taken care shortly. But for now, make
should work. It was tested with linux and linux-dri. Linux-cell and linux-llvm
might require some minor tweaks.

This is in a separate commit to ensure renames are properly preserved.
