2009-06-22mesa: create/use a fallback texture when bound texture is incompleteBrian Paul
When a GLSL sampler reads from an incomplete texture it should return (0,0,0,1). Instead of jumping through hoops in all the drivers to make this happen, just create/install a fallback texture with those texel values. Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some GPU lockups when trying to sample from missing surfaces. If a binding table entry is NULL, it seems that sampling sometimes works, but not always (lockup). Todo: create a fallback texture for each type of texture target? (cherry picked from commit 3f25219c7bf0f090502489928f0f018e62c4f6cf)
2009-06-17Fast path when rebinding the same texture in single context environmentIan Romanick
If there is no shared context, there is no purpose in rebinding the same texture. In some artificial tests this improves performance 10% - 30%. (cherry picked from commit 7f8000db8bd45bb95bda4a4f8535c49b8ef74254)

2009-02-22mesa: move a bunch of compiler-related stuff into new compiler.h headerBrian Paul
This trims down and cleans up imports.h and glheader.h quite a bit.
2009-02-21mesa: use an array for current texture objectsBrian Paul
Use loops to consolidate lots of texture object code.
2009-02-21mesa: use an array for default texture objectsBrian Paul
Replace Default1D/2D/3D/Cube/etc with DefaultTex[TEXTURE_x_INDEX]. The same should be done with the Current1D/2D/3D/etc pointers...
2009-02-07mesa: minor fixes to incomplete texture debug codeBrian Paul
2009-01-30mesa: add missing _mesa_reference_texobj() calls for texture array targetsBrian Paul
2009-01-28mesa: remove GL_SGIX_shadow, GL_SGIX_shadow_ambient and GL_SGIX_depth_textureBrian Paul
Everyone should be using the newer/better ARB versions of these extensions.
2009-01-28mesa: set/get new state for GL_EXT_texture_swizzleBrian Paul
2009-01-21mesa: add some debug assertions to detect null current texture object pointersBrian Paul
See bug #17895. These assertions could be removed when this is resolved.
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.
2008-09-21mesa: refactor: move #define FEATURE flags into new mfeatures.h fileKeith Whitwell
Also, check the FEATURE flags in many places. (cherry picked from commit 40d1a40f294f1ed2dacfad6f5498322fc08cc2d1) Conflicts: src/mesa/main/config.h src/mesa/main/context.c src/mesa/main/texobj.c src/mesa/main/texstate.c src/mesa/main/texstore.c

2007-08-16Bring over the texobj refcounting changes from mesa_7_0_branchBrian
2007-08-14Fix a few more problems with freeing FBOs/textures during context destruction.Brian
Free FBOs before textures since the later may be referenced by the former. Need to bind the context we're destroying if there isn't a current context so that ctx->DeleteTexture() etc can be used.
2007-08-13Implement mutex/locking around texture object reference counting.Brian
Use new _mesa_reference_texobj() function for referencing/unreferencing textures. Add new assertions/tests to try to detect invalid usage of deleted textures.

2007-05-16Initial implementation of MESA_texture_arrayIan Romanick
Shadow sampling from texture arrays is still not implemented. Everything else should be there, though.
2007-05-10Refactor the loop in unbind_texobj_from_texunits.Ian Romanick
Common code was pulled out of the per-target if-statment and put at the end of the for-loop. The common code is guarded by a new variable, curr, that is set to point to the unit's current target in each if-statement.

2006-03-20Lots of changes/fixes for rendering to framebuffer objects.Brian Paul
- When deleting texture objects, unbind from FBOs if necessary. - Changed driver hooks for starting/ending render to texture. - Now properly handle case where gl[Copy]TexImage() is called after glFramebufferTexture[123]D(). That didn't work before.
2005-10-05Remove _IsPowerOfTwo from gl_texture_object, not really needed.Brian Paul

_BaseFormat to be consistant with gl_renderbuffer.

2005-02-05Remove the Shared->TexObjectList pointer and Next field from gl_texture_object.Brian Paul
Was only used by two drivers to walk over all texture objects. Can do that via the hash table instead. Cleaned up some comments for struct gl_texture_object.

2005-01-19Change behaviour of glDeleteTextures as discussed on ARB list.Brian Paul
glDeleteTexture makes the texture ID immediately free for re-use while the actual texture object lingers until its reference count goes to zero (when no longer bound by any rendering context).
