* 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?

* mesa: fix up error/warning/debug output newlinesBrian Paul2009-04-242-10/+27
| | | | | | | | | | As of commit 23ad86cfb91c294ce85a3116d4b825aaa3988a6e all messages go through output_if_debug(). Add new parameter to output_if_debug() to indicate whether to emit a newline. _mesa_warning() and _mesa_error() calls should not end their strings with \n. _mesa_debug() calls should end their text with \n.

* mesa: protect driver.flush() with FLUSH_CURRENTKeith Whitwell2009-04-222-8/+8
| | | | | | Need to do this to ensure vbo code unmaps its buffers before calling the driver, which may be sitting on top of a memory manager which objects to firing commands from a mapped buffer.
* mesa: new _NEW_PROGRAM_CONSTANTS flagBrian Paul2009-04-212-1/+36
| | | | | | | | | | | | | | | This state flag will be used to indicate that vertex/fragment program constants have changed. _NEW_PROGRAM will be used to indicate changes to the vertex/fragment shader itself, or misc related state. _NEW_PROGRAM_CONSTANTS is also set whenever a program parameter that's tracking GL state has changed. For example, if the projection matrix is in the parameter list, calling glFrustum() will cause _NEW_PROGRAM_CONSTANTS to be set. This will let to remove the need for dynamic state atoms in some drivers. For now, we still set _NEW_PROGRAM in all the places we used to. We'll no longer set _NEW_PROGRAM in glUniform() after drivers/etc have been updated.

| |/ |/| | | | | | | | | | | | | | | | | This fixes a regression in fbotest1 on 915, where a transition from color+vertex array enabled to texcoord0+vertex array enabled wouldn't trigger program update on the second _mesa_update_state of DrawArrays, and we'd sample a constant texcoord of 0,0,0,1 instead of the array. The double state update in DrawArrays from 1680ef869625dc1fe9cf481b180382a34e0738e7 still needs fixing.

* Mesa: allow suppression of debug messages in a debug buildRobert Ellison2009-04-081-10/+32
| | | | | | | | | | | | | | | | | | | | | For testing, it's very useful to be able to test on a debug build, while suppressing the debug messages (messages that are by default suppressed in a release build), in order to see the same behavior that users of release builds will see. For example, the "piglit" test suite will flag an error on programs that produce unexpected output, which means that a debug build will always fail due to the extra debug messages. This change introduces a new value to the MESA_DEBUG environment variable. In a debug build, explicitly setting MESA_DEBUG to "0" will suppress all debug messages (both from _mesa_debug() and from _mesa_warning()). (The former behavior was that debug messages were never suppressed in debug builds.) Behavior of non-debug builds has not changed. In such a build, _mesa_debug() messages are always suppressed, and _mesa_warning() messages will be suppressed unless MESA_DEBUG is set *to any value*.

| | | | | | This format is layered on MESA_FORMAT_RGB888 so the component order is actually BGR. Fixes glean pixelFormat failures.

* mesa: clamp colors to [0,1] for glGetTexImage() when format is GL_LUMINANCEBrian Paul2009-04-031-4/+6

* mesa: fix TexParameter functionsRoland Scheidegger2009-04-021-62/+86
| | | | | | | | | premature return in TexParameterf caused mesa to never call Driver.TexParameter breaking drivers relying on this (fix bug #20966). While here, also fix using ctx->ErrorValue when deciding to call Driver.TexParameter. Errors are sticky and uncleared errors thus would cause this to no longer get called. Since we thus need return value of set_tex_parameter[if] can also optimize this to only call when value changed.

* swrast: do texture sampling/combining in floating pointBrian Paul2009-04-011-9/+0

* glsl: implement compiling/linking of separate compilation unitsBrian Paul2009-04-011-0/+1
| | | | | | | | | A shader program may consist of multiple shaders (source code units). If we find there are unresolved functions after compiling the unit that defines main(), we'll concatenate all the respective vertex or fragment shaders then recompile. This isn't foolproof but should work in most cases.
* mesa: fix a recursive display list problemBrian Paul2009-04-011-1/+1
| | | | | | | | | | | | | This fixes an issue when compiling glCallList() into another display list when the mode is GL_COMPILE_AND_EXECUTE. Before, the call to glCallList() called _mesa_save_CallList() which called neutral_CallList() which then called _mesa_save_CallList() again. In the end, the parent display list contained two calls to the child display list instead of one. Let's be on the lookout for regressions caused by this change for a while before we cherry-pick this elsewhere.
* mesa: fix bug in GPU codegen for fixed-function two-sided lightingBrian Paul2009-03-311-2/+12
| | | | | | | | | | | | | The 'dots' register wasn't getting properly un-negated and un-swizzled after emitting the code for back-face lighting. So, if more than one light source was enabled, the specular exponent for the next light source was wrong. During execution we were evaluating pow(x, y) where y was negative instead of positive. This led to the outcome being zero or NaN. This fixes the occasional black triangles seen in isosurf when hacked to enable two-sided lighting.
