* mesa: call ctx->Driver.ChooseTextureFormat() only when necessary.Brian Paul2010-07-201-6/+3
| | | | | | | | | | | | | | | | | | | When defining mipmap level 'L' and level L-1 exists and the new level's internalFormat matches level L-1's internalFormat, then use the same hw format. Otherwise, do the regular ctx->Driver.ChooseTextureFormat() call. This avoids a problem where we end up choosing different hw formats for different mipmap levels depending on how the levels are defined (glTexImage vs. glCopyTexImage vs. glGenerateMipmap, etc). The root problem is the ChooseTextureFormat() implementation in some drivers uses the user's glTexImage format/type parameters in the choosing heuristic. Later mipmap levels might be generated with different calls (ex: glCopyTexImage()) so we don't always have format/type info and the driver may choose a different format. For more background info see the July 2010 mesa-dev thread "Bug in _mesa_meta_GenerateMipmap"
* Merge branch 'shader-file-reorg'Brian Paul2010-06-232-9/+7
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Move all GL entrypoint functions and files into src/mesa/main/ This includes the ARB vp/vp, NV vp/fp, ATI fragshader and GLSL bits that were in src/mesa/shader/ 2. Move src/mesa/shader/slang/ to src/mesa/slang/ to reduce the tree depth 3. Rename src/mesa/shader/ to src/mesa/program/ since all the remaining files are concerned with GPU programs. 4. Misc code refactoring. In particular, I got rid of most of the GLSL-related ctx->Driver hook functions. None of the drivers used them. Conflicts: src/mesa/drivers/dri/i965/brw_context.c

* | Revert "Fix image_matches_texture_obj() MaxLevel check"Will Dyson2010-06-191-0/+3
|/ | | | | | | | | | | | | This reverts commit a9ee95651131e27d5acf3d10909b5b7e5c8d3e92. It was based on a failure to understand how ther driver allocates memory, and causes a regression with Celestia. Set MaxLevel to dstLevel before allocating new mipmap level. The radeon driver will fail to allocate space for a new level that is outside of BaseLevel..MaxLevel. Set MaxLevel before allocating. Signed-off-by: Maciej Cencora <[email protected]>
* meta: Convert Z value from normalized to object-space in meta codeBrian Paul2010-05-241-4/+19
| | | | | | | | | | | | | | Convert Z from a normalized value in the range [0, 1] to an object-space Z coordinate in [-1, +1] so that drawing at the new Z position with the default/identity ortho projection results in the original Z value. Used by the meta-Clear, Draw/CopyPixels and Bitmap functions where the Z value comes from the clear value or raster position. Fixes piglit tests fdo23670-depth_test, quad-invariance and glsl-orangebook-ch06-bump as well as oglc zbfunc.c. https://bugs.freedesktop.org/show_bug.cgi?id=23670
* mesa: more transform feedback infrastructureBrian Paul2010-05-101-0/+7

* mesa: remove driver hooks for GetFloat/Integer/Doublev, etcBrian Paul2010-05-071-8/+0
| | | | | Once upon a time some drivers hooked into these for GL_HP_occlusion_test and GL_OES_read_format. They're not being used anymore so get rid of them.

* meta: Use the DrawBuffer's stencil sizeIan Romanick2010-03-051-1/+1
| | | | | | | | | Previously the code was erroneously using the stencil size of the context instead of the stencil size of the DrawBuffer. With FBOs these may be different. As a result, clearing the stencil buffer of an FBO bound to a context that doesn't have stencil would fail. Signed-off-by: Ian Romanick <[email protected]>
* mesa: Remove ClearIndex and IndexMask from device-driver interfaceIan Romanick2010-03-031-2/+0

* | mesa: implement per-buffer color maskingBrian Paul2009-12-292-14/+40
| | | | | | | | | | | | | | | | | | | | | | This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0. The ctx->Color.ColorMask field is now a 2-D array. Until drivers are modified to support per-buffer color masking, they can just look at the 0th color mask. The new _mesa_ColorMaskIndexed() function will be called by glColorMaskIndexedEXT() or glColorMaski().
* | mesa: per-buffer blend enabled flagsBrian Paul2009-12-291-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ctx->Color.BlendEnabled is now a GLbitfield instead of a GLboolean to indicate blend on/off status for each color/draw buffer. This is infrastructure for GL_EXT_draw_buffers2 and OpenGL 3.x New functions include _mesa_EnableIndexed(), _mesa_DisableIndexed(), and _mesa_IsEnabledIndexed(). The enable function corresponds to glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3. Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0 unless GL_EXT_draw_buffers2 is enabled.
