* mesa: add new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment program inputsBrian Paul2009-07-291-4/+5
| | | | | | | | | | Previously, the FOGC attribute contained the fragment fog coord, front/back- face flag and the gl_PointCoord.xy values. Now each of those things are separate fragment program attributes. This simplifies quite a few things in Mesa and gallium. Need to test i965 driver and fix up point coord handling in the gallium/draw module...

| * mesa: fix texture border color code for glPopAttrib()Brian Paul2009-07-141-7/+1

| | | | | | | | | | | | | | | | | | The values 2147483648.0 and 4294967294.0 are too larget to be stored in single precision floats. Forcing these to be singles causes bits to be lost, which results in errors in some pixel transfer tests. This fixes bug #22344. (cherry picked from commit 70e72070fce6aa1e0918dcc62c1949465cee69f7)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | two) The semantics are a little different for shaders vs. fixed-function when trying to use an incomplete texture. The fallback texture returning (0,0,0,1) should only be used with shaders. For fixed function, the texture unit is truly disabled/ignored. Fixes glean fbo test regression.

| | | | | | | | | | | | | | | | 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.

| * mesa/dlist: fixes and improvements for material cachingKeith Whitwell2009-06-301-8/+16
| | | | | | | | | | | | | | | | | | | | | | Only short-circuit material call if *all* statechanges from this call are cached. Some material calls (eg with FRONT_AND_BACK) change more than one piece of state -- need to check all of them before returning. Also, Material calls are legal inside begin/end pairs, so don't need to be as careful about begin/end state as with regular statechanges (like ShadeModel) when caching. Take advantage of this and do better caching.
| * mesa/dlist: don't cache state which may not be replayed on CallListKeith Whitwell2009-06-301-1/+5
| | | | | | | | | | | | | | | | | | Statechanges which occur before the first End in a display list may not be replayed when the list is called, in particular if it is called from within a begin/end pair. Recognize vulnerable statechanges and do not use them to fill in the state cache.
| * mesa/dlist: invalidate cached dlist compile state after CallListKeith Whitwell2009-06-301-16/+24
| | | | | | | | | | | | When compiling a display list containing a CallList, it is necessary to invalidate any assumption about the GL state after the recursive call completes.

| * | mesa/dlist: restore missing SAVE_FLUSH_VERTICES in save_ShadeModelKeith Whitwell2009-06-301-0/+1
| | | | | | | | | | | | | | | Reorganization of ShadeModel to avoid flushing vertices too often ended up never flushing vertices due to omitted line of code.
| * | mesa: add debug printer for primitive nameKeith Whitwell2009-06-302-0/+28
| | | | | | | | | | | | | | | | | | Add a simple version of _mesa_lookup_enum_by_nr() which expects a primitive enum (GL_POINTS..GL_POLYGON). This avoids some annoying duplicates when looking up primitives, such as the GL_FALSE/GL_POINTS clash.
| * | mesa/dlist: shortcircuit some redundant statechanges at compile timeKeith Whitwell2009-06-302-19/+51
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, state-changes in mesa display lists are more or less a verbatim recording of the GL calls made during compilation. This change introduces a minor optimization to recognize and eliminate cases where the application emits redundant state changes, eg: glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() The big win is when we can eliminate all the statechanges between two primitive blocks and combine them into a single VBO node. This commit implements state-change elimination for Material and ShadeModel only. This is enough to make a start on debugging, etc.

| * | mesa: create/use a fallback texture when bound texture is incompleteBrian Paul2009-06-224-2/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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?
