same slot
This fixes the glsl/bump.c and glsl/texdemo1.c programs
|
|
If the vertex program writes to an output that's not consumed by the
fragment program, map the vp output to an unused slot.

This was part of Keith's patch from Friday.
|
|
- Remove put/get tile, just have users call put_tile_raw, etc directly.
- Remove surface_data call, just map it locally.

undefined state

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.

Provide an actual definition of the pipe_buffer struct, containing
the parameters used to create the buffer, and its refcount.
Shift refcounting buffers out of the winsys interface, similar to
surfaces & textures.
Rework pipebuffer/ to reflect the fact these changes, and also Michel's
reworking of the buffer interface.
|
|
The properties of a buffer represented by struct pipe_buffer_handle are now
basically constant over its lifetime. The state tracker gets to deal with any
more complex buffer semantics it may need to provide.

now.
|
|
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.

This reverts commit 310e7ca44b33558a9aa22f43024d1bfb63642128.

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
|
|
This allows a few more programs to run and not crash.
Need to get constant buffer uploads working...

The CSO returned by pipe->create_vs_state() can't be passed to the
private draw module. That was causing glRasterPos to blow up.
Add a 'draw_shader' field to st_vertex_program for use with the private
draw module.
Change st_context->state.vs type from cso_vertex_shader to st_vertex_program.
|
|
pipe_get/put_tile_rgba() now use pipe->get/put_tile internally.
Also simplify the <format>_get/put_tile_rgba() helper functions and clean up
some inconsitencies in them.
|
|
It's now the responsibility of surface users to keep track of their mappings.
|
|
Also make enum pipe_format used in a couple more places.

If an app never called glViewport, the viewport size was always 0 by 0 pixels.
Now pass initial size to st_create_framebuffer() and initialize the viewport
and scissor bounds in st_make_current().
This could also be fixed by ensuring the gl_framebuffers passed to
_mesa_make_current() were initialized to the right size. But that involves
allocating the renderbuffers/pipe_surfaces earlier and that runs into some
other issues ATM.
Also remove obsolete createRenderbuffers param to st_create_framebuffer().

Remove dst_offset (not used)
Add nr_components, which could be calculated from format, but would be
too much effort.
Update i965 driver to cope.

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.

This fixes the glsl/texdemo1.c program.

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.

st_create_framebuffer() now takes pipe_formats for the color, depth, stencil
buffers.
This avoids a round-about chain of calls to pipe->is_format_supported() for
window renderbuffers (their format never changes).
Renderbuffer format selection code in st_format.c is simpler now too.
