* i965: Disentangle VS constant surface state from WM surface state.Eric Anholt2009-05-067-186/+255
| | | | | 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.
* i965: Don't create constant buffers if they won't be used.Eric Anholt2009-05-061-1/+17
| | | | | | | | 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.

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.

| | | | | | This reverts commit a0edbfb28fb2e670c657d52190a7e8b1ccf4f46e. This patch didn't completely fix the problem. The next patch will.

| * gallium: fix texcoords for cubemap mipmap generationBrian Paul2009-05-051-10/+86
| | | | | | | | | | 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.

* | mesa: more complete fix for transform_invarient glitchesKeith Whitwell2009-05-056-11/+153
| | | | | | | | | | | | 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.
* | mesa/main: set PREFER_DP4 to match position_invarient codeKeith Whitwell2009-05-051-1/+1
| | | | | | | | | | | | | | | | 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.

* | mesa: in glReadBufer() set _NEW_BUFFERS, not _NEW_PIXELBrian Paul2009-05-016-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * st: create renderbuffer's pipe_surface in st_render_texture()Brian Paul2009-05-011-1/+11
| | | | | | | | | | | | 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.
| * mesa: fix state validation bug for glCopyTex[Sub]Image()Brian Paul2009-05-011-5/+16
| | | | | | | | | | 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.
* | st: if st_swapbuffers() is called for single-buffered visual don't crashBrian Paul2009-05-011-1/+19
| | | | | | | | Furthermore, return pointer(s) to the front color buffer(s).
* | xlib winsys: use new st_swapbuffers() functionBrian Paul2009-05-011-14/+7
| | | | | | | | | | | | | | | | | | | | 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.
* | st: when creating an on-demand front color buffer, init to back buffer imageBrian Paul2009-05-011-1/+31
| | | | | | | | | | | | 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.
* | st: added st_renderbuffer::defined flagBrian Paul2009-05-016-2/+28
| | | | | | | | | | | | | | | | | | | | 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.

| * Fix symbol list for mangled Mesa on Darwin.Tom Fogal2009-05-011-59/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | set: new st_swapbuffers() which does a true front/back buffer swapBrian Paul2009-05-012-0/+83
| | | | | | | | | | The pointers to the front/back renderbuffers are exchanged. This new function isn't actually used yet...
* | egl_xlib: Pass RTLD_LAZY to dlopen.José Fonseca2009-05-011-1/+3
| | | | | | | | | | 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.
* | Test either GL_FRONT_LEFT or GL_FRONT for front-buffer renderingIan Romanick2009-05-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

* | st: when double buffered, only create front color buffer on demandBrian Paul2009-05-012-8/+109
| | | | | | | | | | Before we always created the front color buffer, even if was never used. This can save some memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Make the use_const_buffer field per-program and only call the code which updates the constant buffer's data if the flag is set. This should undo the perf regression from 20f3497e4b6756e330f7b3f54e8acaa1d6c92052 (cherry picked from master, commit dc9705d12d162ba6d087eb762e315de9f97bc456)
