* 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.

| * | i965: only upload constant buffer data when we actually need the const bufferBrian Paul2009-04-276-17/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
| * | i965: rework GLSL/WM register allocationBrian Paul2009-04-242-48/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | Use a bitvector of used/free flags. If we run out of temps, examine the live intervals of the temp regs in the program and free those which are no longer alive. Also, enable the new WM const buffer code.

| * | mesa: signal _NEW_PROGRAM_CONSTANTS instead of _NEW_PROGRAMBrian Paul2009-04-243-10/+11
| | | | | | | | | | | | | | | Use _NEW_PROGRAM_CONSTANTS when changing constant/uniform buffer values. Binding a new program/shader sets both _NEW_PROGRAM and _NEW_PROGRAM_CONSTANTS.

| * | i965: enable VS constant buffersBrian Paul2009-04-221-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the VS constants can now be handled in two different ways: 1. If there's room in the GRF, put constants there. They're preloaded from the CURBE prior to VS execution. This is the historical approach. The problem is the GRF may not have room for all the shader's constants and temps and misc registers. Hence... 2. Use a separate constant buffer which is read from using a READ message. This allows a very large number of constants and frees up GRF regs for shader temporaries. This is the new approach. May be a little slower than 1. 1 vs. 2 is chosen according to how many constants and temps the shader needs.

| * | i965: checkpoint commit: use two state caches instead of oneBrian Paul2009-04-224-45/+88
| | | | | | | | | | | | | | | | | | | | | The new, second cache will only be used for surface-related items. Since we can create many surfaces the original, single cache could get filled quickly. When we cleared it, we had to regenerate shaders, etc. With two caches, we can avoid doing that.

| * | i965: the brw_constant_buffer state atom is no longer dynamicBrian Paul2009-04-222-33/+5
| | | | | | | | | | | | No more dynamic atoms so we can simplify the state validation code a little.

| * | i965: use _NEW_PROGRAM_CONSTANTS and always create new const buffersBrian Paul2009-04-221-14/+14
| | | | | | | | | | | | | | | | | | When program constants change we create a new VS constant buffer instead of re-using the old one. This allows us to have several const buffers in flight with vertex rendering.

| | | | | | | | | | | | | | | | | | Make sure we detect constant buffer changes indicated by the new flag. Should be able to remove _NEW_PROGRAM (and _NEW_MODELVIEW, _NEW_LIGHT, etc) from several places (someday.
* | | mesa: create/use a fallback texture when bound texture is incompleteBrian Paul2009-05-014-2/+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?

* | egl: Don't install demodriverDan Nicholson2009-04-291-2/+0
| | | | | | | | | | | | | | I don't think anyone besides a developer would ever want to use the demo egl driver. Furthermore, egl would only ever load demodriver if it was set via EGL_DRIVER in the environment. In that case, I think you can point it to your mesa source directory.
* | Use variable library name in pkg-config output.Tom Fogal2009-04-2910-10/+15
| | | | | | | | | | | | | | | | | | | | | | Previously the pkg-config output files would contain e.g. `-lGL' and `-lGLU', even if the user modified their configuration to build libraries with different names. This modifies the pkg-config inputs, and corresponding makery, so that modifying the output library name will cause the appropriate updated name to appear in the pkg-config `-l' option.
