2009-05-06i965: Split WM constant buffer update from other WM surfaces.Eric Anholt
This can avoid re-uploading constant data when it isn't necessary, and is a step towards not updating other surfaces just because constants change. It also brings the upload of the constant buffer next to the creation. This brings openarena performance up another 4%, to 91% of the Mesa 7.4 branch.
2009-05-06i965: Disentangle VS constant surface state from WM surface state.Eric Anholt
Also, only create VS surface state if there's a VS constant buffer to be uploaded, and set the contents of the buffer at the same time as creation.
2009-05-06i965: Don't create constant buffers if they won't be used.Eric Anholt
Really, the creation and upload of constants should be in the same place, since they should only happen together, and a state flag should be triggered by them so that we don't thrash state around so much for just updating constants. But this still recovers openarena performance by another 19%, leaving us 16% behind Mesa 7.4 branch.
2009-05-05mesa: only use fallback texture when using shaders, not fixed-function (take ↵Brian Paul
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.

2009-05-05gallium: fix texcoords for cubemap mipmap generationBrian Paul
We need to use (s,t,r) cubemap coords when sampling from the cubemap texture so the rendered quad gets texture samples from the correct cube face.
2009-05-05mesa: more complete fix for transform_invarient glitchesKeith Whitwell
Add a new flag mvp_with_dp4 in the context, and use that to switch both ffvertex.c and programopt.c vertex transformation code to either DP4 or MUL/MAD implementations.
2009-05-05mesa/main: set PREFER_DP4 to match position_invarient codeKeith Whitwell
This is a quick fix for z fighting in quake4 caused by the mismatch between vertex transformation here and in the position_invarient code. Full fix would be to make this driver-tunable and adjust both position_invarient and ffvertex_prog.c code to respect driver preferences.

2009-05-01mesa: in glReadBufer() set _NEW_BUFFERS, not _NEW_PIXELBrian Paul
Since GL_READ_BUFFER is historically part of the gl_pixel_attrib group it made sense to signal changes with _NEW_PIXEL. But now with FBOs it's also part of the framebuffer state. Now _NEW_PIXEL strictly indicates pixels transfer state changes. This change avoids framebuffer state validation when any random bit of pixel-transfer state is set. DRI drivers updated too: don't check _NEW_COLOR when updating framebuffer state. I think that was just copied from the Xlib driver because we care about dither enable/disable state there.

2009-05-01st: create renderbuffer's pipe_surface in st_render_texture()Brian Paul
Previously we created the pipe_surface during framebuffer validation. But if we did a glCopyTex[Sub]Image() before anything else we wouldn't yet have the surface. This fixes that.
2009-05-01mesa: fix state validation bug for glCopyTex[Sub]Image()Brian Paul
We need to make sure the framebuffer state is up to date to make sure we read pixels from the right buffer when doing a texture image copy.
2009-05-01st: if st_swapbuffers() is called for single-buffered visual don't crashBrian Paul
Furthermore, return pointer(s) to the front color buffer(s).
2009-05-01xlib winsys: use new st_swapbuffers() functionBrian Paul
The front/back buffer pointers are truly swapped (when there is an actual front buffer). This fixes some issues seen with apps/tests that draw to both the front and back color buffers. The true swap allows us to avoid the (potentially) slow surface_copy() call in update_framebuffer_state() and is cleaner overall.
2009-05-01st: when creating an on-demand front color buffer, init to back buffer imageBrian Paul
When we create a new front color buffer (user called glDrawBuffer(GL_FRONT)) initialize it to the contents of the back buffer. Any previous call to SwapBuffers() would have done that in effect, so make it reality.
2009-05-01st: added st_renderbuffer::defined flagBrian Paul
Indicates whether there's defined image contents, or garbage/don't care. This is set when we draw into a renderbuffer and cleared when we resize/ reallocate a renderbuffer or do a buffer swap (back buffer becomes undefined). We use this to determine whether the front color buffer has been drawn to, and whether to display its contents upon glFlush/Finish(), when the new st_swapbuffers() function is used.

2009-05-01Fix symbol list for mangled Mesa on Darwin.Tom Fogal
When building mangled Mesa on Darwin, the exported symbols are named `_mgluWhatever' instead of simply `_gluWhatever'. When using a list of exported symbols via the system ld's `-exported_symbols_list' command line option (as done by mklib), this resulted in error messages about exporting symbols which do not exist. Fortunately the file format accepts simple wildcards. This throws a wildcard so that the symbol list will match both the mangled and non-mangled names, preventing the warning and actually exporting the correct symbols in one shot.
2009-05-01set: new st_swapbuffers() which does a true front/back buffer swapBrian Paul
The pointers to the front/back renderbuffers are exchanged. This new function isn't actually used yet...
2009-05-01egl_xlib: Pass RTLD_LAZY to dlopen.José Fonseca
dlopen manpage mandates that either RTLD_LAZY or RTLD_NOW flags must be passed. Not doing so was causing a NULL return on debian unstable x86-64.
2009-05-01Test either GL_FRONT_LEFT or GL_FRONT for front-buffer renderingIan Romanick
For non-stereo visuals, which is all we support, we treat GL_FRONT_LEFT as GL_FRONT. However, they are technically different, and they have different enum values. Test for either one to determine if we're in front-buffer rendering mode. This fix was suggested by Pierre Willenbrock. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
2009-05-01st: when double buffered, only create front color buffer on demandBrian Paul
Before we always created the front color buffer, even if was never used. This can save some memory.

2009-05-01mesa: 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?
