This is basically half of Keith's draw/flush patch.
The stage->point/line/tri() functions are now self-validating, the validator
functions are installed by the flush() function.
There were excessive calls to validate_pipeline(), however. This was caused
by draw_prim_queue_flush() keeping a local 'first' variable that always pointed
to the validate functions. Replaced 'first' with 'draw->pipeline.first'.
Performance in gears is up just slightly with this patch.

fs inputs
Some follow-on simplification in prim setup is possible...

Now based on the draw_vbuf code, instead being a custom one-off.
Disabled by default, enable with SP_VBUF env var.
|
|
Remove all dependencies on vertex_info, except for draw_vbuf.
Drawing stages now strictly operate on post-transformed vertices and don't
know anything about hw vertices.
Use vertex program output info for two-side/flat/etc stages.
Temporarily disable vbuf module in softpipe driver.

These are changes that are in our internal branch, but somehow were skipped
so far. It was done using visual comparison of the branches --
it is likely that changes are being carried on the wrong way

Note that fogcoord and front-facing attribs are in the same register, in the
X and Y channels, respectively.

This controls whether the window origin is considered to be the lower-left
or upper-left corner.
This effects computation of gl_FragCoord and the application of polygon stipple.

We were doing this for the sake of softpipe and the tgsi intergrepter since
we always need the fragment position and W-coordinate information in order
to compute fragment interpolants.
But that's not appropriate for hardware drivers.
The tgsi interpreter now get x,y,w information from a separate tgsi_exec_vector
variable setup by softpipe.
The new pipe_shader_state->input_map[] defines how vert shader outputs map
to frag shader inputs. It may go away though, since one can also examine
the semantic label on frag shader input[0] to figure things out.

Use FREE, MALLOC, CALLOC, GETENV wrappers.
Silence compiler warnings.
Add proper copyrights.

typedefs are rather evil, remove them and use the enum
keyword explicitely.

Build a buffer of contigous vertices and indices at the backend of our
software transformation/clipping path. This will become the mechanism
for emitting buffers of vertices to rasterization hardware.
This is similar to but not the same as the post-transform vertex cache.
In particular, these vertices are subject to clipping, culling, poly offset,
etc. The vertices emitted will all be used by hardware.
TODOs include the actual transformation to hardware vertex formats, moving
this out of softpipe to somewhere more useful and allowing >1 primitive to
share the generated VB.

Remove/disable the attrib/slot mapping arrays in a few places.
Work in progress...

This is a step toward removing TGSI_ATTRIB_ tokens.
Basically, when translating Mesa programs to TGSI programs, pass in input and
output register re-maps, plus interpolation info.
There's some known breakage (cubemap.c) so more to be done...

to cpy.
One less dependency on the TGSI_ATTRIB_x flags.
This requires setting the vertex_info->interp_mode[] values in the i915 driver and passing them to draw_set_vertex_attributes().
|
|
The code is all in place, but mostly disabled for now:
In t_vp_build.c, write the VERT_RESULT_PSIZE register
In sp_state_derived.c, need to emit vertex point size if drawing points.
In setup_point() use the point size from the vertex.

Replace VF_ATTRIB_x with TGSI_ATTRIB_x
When converting mesa programs to TGSI programs, also convert the InputsRead
and OutputsWritten to a mask of TGSI_ATTRIB_ bits.
Still need to do conversion for vertex programs...

To build with mesa, need -DMESA in makefile/config file.

This prevents rendering out of bounds when the viewport is partially outside the surface bounds.
