2008-12-31mesa: increase max texture image units and GLSL samplers to 16Brian Paul
The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.
2008-12-31intel: Share passthrough transform setup between glBitmap and glDrawPixels.Eric Anholt
The DrawPixels path was missing glViewport care, so blender's toolbar icons would go to the wrong places. Bug #19118.
2008-12-31intel: Add support for glBitmap as metaops using GL calls.Eric Anholt
This lets us avoid software fallbacks when clients forget to turn some state off (engine demo) or just do crazy things to test conformance (OGLC). This should probably be brought into mesa generic code so other drivers can make use of it. Bug #19016.
2008-12-30mesa: fix bug in evaluation of structure fieldsBrian Paul
Fixes incorrect size information. See bug 19273.
2008-12-30mesa: allow variable indexing into the predefined uniform variable arraysBrian Paul
This allows code such as "vec4 a = gl_LightSource[i].ambient;" to work. When a built-in uniform array is indexed with a variable index we need to "unroll" the whole array into the parameter list (aka constant buffer) because we don't know which elements may be accessed at compile-time. In the case of the gl_LightSource array of size [8], we emit 64 state references into the parameter array (8 elements times 8 vec4s per gl_LightSourceParameters struct). Previously, we only allowed constant-indexed references to uniform arrays (such as gl_LightSource[2].position) which resulted in a single state reference being added to the parameter array, not 64. We still optimize this case. Users should be aware that using "gl_LightSource[i].ambient" in their shaders is a bit expensive since state validation will involve updating all 64 light source entries in the parameter list.

2008-12-30intel: disable ATI_texture_env_combine3 for i830( and related device).Xiang, Haihao
Thanks to Eric for pointing it out.
2008-12-29dri: Fix driWaitForMSC32 when divisor >= 2 and msc < 0.Eric Anholt
We'd come up with a negative remainder, while we were looking for the positive version of it in the loop conditional. And, since the "did we hit our target" break was disabled for the target_msc == 0 ("Just make the divisor/remainder work") path, we'd never exit. Simplify the code by just using int64_t all over instead of trying to do it in a u32 space.

2008-12-29intel: enable ATI_texture_env_combine3. Fixes #17707Xiang, Haihao
2008-12-28r300: remove the unknowns from the indx_buffer codeDave Airlie
2008-12-24i915: separate the fog term from the specular color term.Xiang, Haihao
Previously fog parameter and specular color are packed into the same dword. Note specular color should be packed in BGRA for device, so if fog parameter and specular color all are present, fog parameter will dirty the alpha term of specular color. This fixes rendering issue when playing 'Yo Frankie' on 915/945.
2008-12-23intel: Fix glBitmap clipping for DRI1.Eric Anholt
2008-12-23Remove third buffer support from Mesa.Dave Airlie
This is part of the deprecated pageflipping infrastructure.
2008-12-19Add do_row_3d for mipmapping 3D texturesIan Romanick
Previously 3D textures were mipmapped using multiple passed through the 2D mipmap generation code. This had 3 disadvantages. First, the extra passes were slow. Second, this required the allocation of a temporary buffer to hold intermediate data. Third, and most important, the extra passes caused loss of additional bits due to integer division / bit-shifting. With this change, our mipmapgen conformance test passes for non-compressed texture formats.

2008-12-19965 / GLSL: Use full precision for EXP instructionIan Romanick
The partial precision mode doesn't have quite enough bits of precision to pass conformance tests.
2008-12-19GLSL: The LOG2 macro doesn't have enough precisionIan Romanick
It looks like the LOG2 macro only has 8 or 9 bits of precission, but the ARB_vertex_program spec says "accurate to at least 10 bits".
2008-12-19intel: Fix glBitmap top/bottom clipping.Eric Anholt
Bug #19139.
2008-12-19intel: Don't forget the source bitmap size when clipping the size we draw.Eric Anholt

2008-12-19intel: don't clip to scissor-clipped read framebuffer bounds in copypixels.Eric Anholt
2008-12-18intel: Move copyteximage source clipping out of copytexsubimage.Eric Anholt
glCopyTexSubImage already gets the (correct) clipping for us, so it doesn't need the path. While moving the clipping out, replace the code with the mesa path to do the same job.
2008-12-18mesa: Clip copytexsubimage to read framebuffer bounds, not scissor region.Eric Anholt
2008-12-18mesa: Correct _mesa_clip_to_region() off-by-one.Eric Anholt
Note how if: x + width == xmax + 0: width -= 0 x + width == xmax + 1: width -= 0 x + width == xmax + 2: width -= 1 So, the function was clipping to [xmin, xmax+1), not [xmin, xmax) like it was supposed to. Same for ymax.

2008-12-14Perform range checking on app supplied texture base levelIan Romanick
It is possible for applications to specify any texture base level, including trivially invalid values (i.e., 47000000). When an app specifies an invalide base level, we should gracefully disable the texture instead of accessing memory outside the gl_texture_object. This fixes an occasional segfault in one of our conformance tests.
