If you have a GPU using this code and it has the offsets up in this space,
this fails.
|
|
Since ARB_fragment_program and friends are defined to ignore the setting of
the GL_TEXTURE_COMPARE_FUNC parameter, we have to explicitly enable the
shadow comparison by marking the texture unit in ShadowSamplers when
appropriate.
|
|
All newly created programs have RefCount == 1, but the fragment program cache
added an additional reference in cache_item, with the result being that none
of the programs were ever freed.
Solve the problem by not creating the additional reference in cache_item.
|
|
Removes some compiler #ifdef stuff.
|
|
|
|
When purging the program hash table, the refcount _should_ be one since
the program is referenced by the hash table. Need to explicitly set to
zero before calling delete().
Also, purge high-level shader hash tables before low-level program hash tables.

Previously, the shader linker combined the uniforms used by the vertex and
fragment shaders into a combined set of uniforms. This made the implementation
of glUniform*() simple, but was rather inefficient otherwise. Now each shader
gets its own set of uniforms (no more modelview matrix showing up in the
fragment shader uniforms, for example).

I'll fix this using the mipmap hooks I just picked from gallium-0.1

This at least stops the compiz brain explosion we were seeing, I do wonder
though if we should somehow be calling intel_generate_mipmap somehow.

Use _mesa_reference_vert/fragprog() wherever we assign program pointers.
Fixes a memory corruption bug found with glean/api2 test.
|
|
|
|
Use floor() to convert to int (per Mark Kildard and the SI).
Also, change translate_id() to return a signed integer since we may be
offsetting from GL_LIST_BASE.

GL_REPLACE_EXT comes from the ancient GL_EXT_texture extension. Found an old demo that
actually uses it.
The values of the GL_REPLACE and GL_REPLACE_EXT tokens is different, unfortunately.

Fixes problem with bitmaps jumping around by one pixel depending on window
size. The rasterpos is often X.9999 instead of X+1.
Run progs/redbook/drawf and resize window to check.

shader/shader program objects to avoid memory access error.

More such shader functions are needed...

We always need to do PBO validation, so do that in core Mesa before calling driver routine.
|

|
Helper functions for (some) drivers, including swrast.
|

In _mesa_Bitmap, can't early return if bitmap ptr is NULL, it may be an offset
into a PBO. Similarly for _mesa_GetTexImage.

fix double free issue(bug#14710). It also corrects glsl/bitmap demo behavior.
|

Currently a callback delete_shader_cb is used for deleting shader
and shader program objects. Mesa detaches all attached shaders in
_mesa_free_shader_program_data when deleting shader program objects. However
it is likely that these shaders have been freed in _mesa_free_shader,
which will result in unexpected behaviour. This fix uses a single callback for
shader program objects and deletes shader program objects before shader objects.

They're changed by the intel driver implementation and thus not const.
Fixes compilation warning.
|
|
|
|
Avoids AVC warnings when allocating executable memory by first checking
if the current process has permission to do so.
|
|
When generating a fragment program from fixed function, checking
texUnit->_ReallyEnabled is not sufficient, need texUnit->Enabled too
since the former also represents texture enables from an active vertex
shader.
