PIPE_MAX_SHADER_INPUTS
|
|
as-is in vbuf code
|
|
|
|
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.
|
|
Also, added draw_convert_wide_points/lines() so a driver can tell the draw
module whether to convert wide points/lines into triangles, or just pass
them through.

|
post-xform vertex attribs to hw vertex attribs
|
|
Just pass in the vertex_info object and make a copy of it.
|
|
No longer store the vertex header and clip pos info in the draw module's
vertex_info. The vertex_info just describes the data[] elements.
This simplifies the code in several places.
|
|
typedefs are rather evil, remove them and use the enum
keyword explicitely.
|
|
|
|
|
|
|
|
Remove/disable the attrib/slot mapping arrays in a few places.
Work in progress...
|
|
|
|
|
|
A few functions which were basically duplicated between softpipe and the
i915 driver are now re-used:
draw_emit_vertex_attr()
draw_compute_vertex_size()
|
|
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().
|
|
|
|
|
|
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...
|
|
This also includes legacy #defines for VF_ATTRIB_*, FRAG_ATTRIB_*, etc tokens.
Those will go away eventually, but at least we no longer need vf/vf.h
