They don't work with private back buffers yet.
This gets vsync working.

In mesa_to_tgsi.c, use TGSI_INTERPOLATE_PERSPECTIVE by default (to match
post-transform vertex info convention). More to be done there...
In sp_quad_fs.c, interpolate W in addition to Z. This fixes the divide
by zero happening in perspective_interpolation() tgsi_exec.c
As it was, we were only getting perspective correction of texture coords
used by the TGSI_TEX instruction since it does a homogeneous divide.
Other coords/varyings were incorrect.

Bind when the currently bound state is /not/ the one
we just found/created.

state
|
|
Converting depth and stencil objects into a single state object
(d3d10 like) and making it immutable.
|
|
The const is there to enforce the immutable state of the object,
which is in reality owned by the pipe so just cast away the
constness.
|
|
Switch the sample to be an immutable state object.
|
|
Replacing mesa's main hash with one that handles collisions, moving state_tracker
related caching to the state tracker to keep cso cache independent of it. Cleanups.
|
|
We want our state objects to be immutable, handled via the
create/bind/delete calls instead of struct propagation.
Only implementing the blend state to see how it would look like
and work.

Must have missed this a while back. This fixes cube mapping.
|
|
Not quite finished yet.
Selection/feedback are done with a private instance of the 'draw' module
in the state tracker. Not quite all the draw context's state is set yet,
namely vertex format info. Hold off on that for a bit...

git+ssh://brianp@git.freedesktop.org/git/mesa/mesa into softpipe_0_1_branch
|

This is already handled by the semanics of map(), etc.

Correctly clear the pointer to the old buffer (not sure how this could build at
all before...) and only reference the new one when its pointer is non-NULL.

This replaces the temporary occlusion counter functions we had before.
Added new ctx->Driver.WaitQuery() function which should block until the result is ready.
Sketch out some code for vertex transformation feedback counters.

This will be used for:
GL_NV_transform_feedback, or similar GL3 functionality
glRasterPos
GL selection/feedback modes
|
|
This will be used for:
GL_NV_transform_feedback, or GL3 equivalent.
RasterPos
GL select/feedback modes

ctx->Driver.RasterPos() function.

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()
|
|
Added a new draw_set_twoside_attributes() function for specifying which
vertex attributes are to be copied/replaced when a polygon is back-facing.
|

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().
|
|
In emit_poly() we need to compute header.edgeflags from the vertex
edge flags. Also need to set header.det so later stages can determine
front/back orientation.
|
|
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.
