2010-10-27Track separate programs for each stageIan Romanick
The assumption is that all stages are the same program or that varyings are passed between stages using built-in varyings.
2010-10-13Drop GLcontext typedef and use struct gl_context insteadKristian Høgsberg
2010-07-02mesa: make the number of draw buffers part of the texenv program key stateBrian Paul
All the state that effects the program should be in the key. This didn't help with bug 28169 but is a good fix anyway. NOTE: this is a low-priority candidate for the 7.8 branch. In practice, this issue might never be hit.
2010-06-28mesa: initial support for ARB_geometry_shader4Zack Rusin
laying down the foundation for everything and implementing most of the stuff. linking, gl_VerticesIn and multidimensional inputs are left.

2010-04-05mesa: update_arrays() depends on program state.Henri Verbeet
It uses ctx->VertexProgram._Current. Signed-off-by: Brian Paul <brianp@vmware.com>

2010-01-26mesa: remove redundant _MaxElement computationBrian Paul
Eric added some new code to check if offset < obj_size before computing _MaxElement but my original code was still present afterward and it clobbered the _MaxElement value. Not sure if this came from a bad merge or what.

2009-09-24mesa/main: Make FEATURE_pixel_transfer follow feature conventions.Chia-I Wu
As shown in mfeatures.h, this allows users of pixel.h to work without knowing if the feature is available.
2009-08-07mesa: use a more logical flag in _mesa_set_vp_override()Brian Paul
2009-08-03texenv: Add missing dependency on VP changes.Eric Anholt
Funny thing is I annotated this dependency in e5f63c403b767f9974e8eb5d412c012b8a69287f, but didn't actually use it.
2009-07-16texenv: Calculate whether we need to do secondary color on our own.Eric Anholt
The _TriangleCaps bit is deprecated, not updated when we require, and is set based on state that hasn't been updated at that point in _mesa_update_state_locked(). Fixes incorrect clear color in glsl/twoside.c with meta_clear_tris.
2009-07-14Fix state flag dependencies for fixed function fragment program updates.Eric Anholt
I started looking into why _NEW_ARRAY punishes us, and while annotating dependencies noticed that a bunch of dependencies were missing.
2009-07-07Cap array elements at 0 when passed an invalid pointer for an array object.Eric Anholt
Otherwise, a pointer greater than the size would underflow and give a large maximum element. Reviewed-by: Brian Paul <brianp@vmware.com> (previous version)

2009-05-21mesa: move gl_array_attrib::_MaxElement to gl_array_object::_MaxElementBrian Paul
This value is per array object.
2009-05-07mesa: Compute gl_client_array->_MaxElement during array validationBrian Paul
Used to be done in the glVertex/Normal/Color/etc/Pointer() calls but if the VBO was reallocated the size could change. New _NEW_BUFFER_OBJECT state flag.
2009-05-07mesa: use local var to make code a bit more conciseBrian Paul
2009-04-21mesa: new _NEW_PROGRAM_CONSTANTS flagBrian Paul
This state flag will be used to indicate that vertex/fragment program constants have changed. _NEW_PROGRAM will be used to indicate changes to the vertex/fragment shader itself, or misc related state. _NEW_PROGRAM_CONSTANTS is also set whenever a program parameter that's tracking GL state has changed. For example, if the projection matrix is in the parameter list, calling glFrustum() will cause _NEW_PROGRAM_CONSTANTS to be set. This will let to remove the need for dynamic state atoms in some drivers. For now, we still set _NEW_PROGRAM in all the places we used to. We'll no longer set _NEW_PROGRAM in glUniform() after drivers/etc have been updated.
2009-04-15mesa: Update texenv program when _NEW_ARRAYS is updated as well.Eric Anholt
This fixes a regression in fbotest1 on 915, where a transition from color+vertex array enabled to texcoord0+vertex array enabled wouldn't trigger program update on the second _mesa_update_state of DrawArrays, and we'd sample a constant texcoord of 0,0,0,1 instead of the array. The double state update in DrawArrays from 1680ef869625dc1fe9cf481b180382a34e0738e7 still needs fixing.
2009-03-07mesa: move glViewport and glDepthRange functions into new viewport.c fileBrian Paul
A bit of refactoring with an eye toward ES2 and GL 3.1
2009-03-03mesa: fix sw fallback state validation bugBrian Paul
When a hw driver fell back to swrast, swrast wasn't always getting informed of program changes. When fixed function is translated into shaders, flags like _NEW_LIGHT, _NEW_TEXTURE, etc. should really signal _NEW_PROGRAM. In this case, swrast wasn't seeing _NEW_PROGRAM when new fragment shaders were generated.
2009-03-02mesa: add ctx->Stencil._Enabled fieldBrian Paul
Only true if stenciling is enabled, and there's a stencil buffer.
2009-02-10Merge commit 'origin/gallium-master-merge'Brian Paul
This is the big merge of the gallium-0.2 branch into master. gallium-master-merge was just the staging area for it. Both gallium-0.2 and gallium-master-merge are considered closed now. Conflicts: progs/demos/Makefile src/mesa/main/state.c src/mesa/main/texenvprogram.c
2009-02-10mesa: another fix for program/texture state validationBrian Paul
This fixes a regression introduced in 46ae1abbac6837d051c10b2e8b57eab3d4958ff4 Break program validation into two steps, do part before texture state validation and do the rest after: 1. Determine Vertex/Fragment _Enabled state. 2. Update texture state. 3. Determine pointers to current Vertex/Fragment programs (which may involve generating new "fixed-function" programs). See comments in the code for more details of the dependencies.

consistant with other flags
2009-02-10mesa: fix/change state validation order for program/texture stateBrian Paul
Program state needs to be updated before texture state since the later depends on the former. Fixes piglit texgen failure. The second time through the modes (press 't' three times) we disable the fragment program and return to conventional texture mode. State validation failed here because update_texture() saw stale fragment program state.
2009-01-09mesa: Remove _Active and _UseTexEnvProgram flags from fragment programs.Eric Anholt
There was a note in state.c about _Active deserving to die, and there were potential issues with it due to i965 forgetting to set _UseTexEnvProgram. Removing both simplifies things. Reviewed-by: Brian Paul <brianp@vmware.com>

2008-10-10mesa: new _mesa_set_vp_override() function for driver-override of vertex programBrian Paul
Patch provide by Keith. Used in state tracker by DrawPixels to indicate that the state tracker (driver) is using its own vertex program. This prevents the texenvprogram code from replacing conventional shader inputs with state vars. Fixes glDraw/CopyPixels regressions.

2008-10-03mesa: avoid generating constant vertex attributes in fixedfunc programsKeith Whitwell
Keep track of enabled/active vertex attributes. Keep track of potential vertex program outputs. When generating fragment program, replace references to fragment attributes which are effectively non-varying and non-computed passthrough attributes with references to the new CURRENT_ATTRIB tracked state value. Only downside is slight ugliness in VBO code where we need to validate state twice in succession.
