For some triangles we can generate quads which lie just outside the
surface bounds. Just check the quad's mask before trying to emit/process
the quad.
Fixes failed assertion in Lightsmark.

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flush, causing transfer data to be outdated/clobbered.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.
|
|
Note that this doesn't have any real significance since
PIPE_CAP_ANISOTROPIC_FILTER still returns 0.

Because of flat shading, we can't use same code as PIPE_PRIM_TRIANGLE_FAN.
This is a follow-on to commit a59575d8fbe8b0ca053cc8366ce7a42bc660158a.
(cherry picked from commit 086ecea179ed572c89aa77c5f465671a5cef87a7)

This fixes incorrect front/back-face orientation.

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...
|
|
This fixes the incorrect colors seen when rendering flat-shaded polygons.
Note that clipped polygons were correct, but unclipped polygons were wrong.
See the glean/clipFlat test for regression testing.

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.
|
|
This allows the engine demo to run again (avoid crash in VBO code).
This stuff still needs to be revisited someday though...
|

|
Return the conservative PIPE_REFERENCED_FOR_READ | PIPE_REFERENCED_FOR_WRITE
value for now.
This fixes a bunch of regressions seen in piglit and glean.

Not used by softpipe anyway.
|
|
Also implement context member functions to optimize away those
flushes whenever possible.

Only allows clearing currently bound buffers, but colour and depth/stencil in
a single call.

And print/warn NaN/Inf in print_vertex().

This was used to indicate OpenGL's lower-left origin for fragment window
coordinates for polygon stipple and gl_FragCoord.
Now:
- fragment coordinate origin is always upper-left corner
- GL polygon stipple is inverted and shifted before given to gallium
- GL fragment programs that use INPUT[WPOS] are modified to use an
inverted window coord which is placed in a temp register.
Note: the origin_lower_left field still exists in pipe_rasterizer_state.
Remove it when all the drivers, etc. no longer reference it.

Need to null-out pointers after freeing transfer objects.
Fix mix-ups between tc->transfer and tc->tex_trans fields.
|
|
This fixes a number of crashes/regressions in programs such as lodbias.c,
mipmap_limits.c, etc.

Any driver who needs a copy of the shader tokens must organize to
do so itself. This has been the case for a long time, but there
was still defensive code in the state tracker, which is now removed.
Any bugs resulting from this need to be fixed in the offending driver...
|
|
I should have gotten most uses and implementation
correctly fixed, but things might break.
Feel free to blame me.

This reverts commit 6db24f449de9cc81e1f7bb2dde55a9819463d5e5.
With a null ptr check in align_free() this is no longer needed.
|

Fixes GALLIUM_NOCELL path. See bug 20475.

The core reference counting code is centralized in p_refcnt.h.
This has some consequences related to struct pipe_buffer:
* The screen member of struct pipe_buffer must be initialized, or
pipe_buffer_reference() will crash trying to destroy a buffer with reference
count 0. u_simple_screen takes care of this, but I may have missed some of
the drivers not using it.
* Except for rare exceptions deep in winsys code, buffers must always be
allocated via pipe_buffer_create() or via screen->*buffer_create() rather
than via winsys->*buffer_create().

The template makefile that most libraries in
gallium included was based on dri and had a bunch
unrelevant junk in it.
Update it and improve the depending makefiles.
