* mesa/clear: fix crashes with illegal clear tests.Dave Airlie2012-01-111-4/+11
| | | | | | | | | Mesa shouldn't call into the drivers if there are no renderbuffers bound to the attachments for the buffers to be cleared. Fixes a number of the clearbuffer-* tests on softpipe. Signed-off-by: Dave Airlie <[email protected]>
* mesa: Move RasterDiscard to toplevel of gl_context.Paul Berry2011-12-211-7/+7
| | | | | | | | | | | | | | | | | | | | Previously we were storing the RasterDiscard flag (for GL_RASTERIZER_DISCARD) in gl_context::TransformFeedback. This was confusing, because we use the _NEW_TRANSFORM flag (not _NEW_TRANSFORM_FEEDBACK) to track state updates to it, and because rasterizer discard has effects even when transform feedback is not in use. This patch makes RasterDiscard a toplevel element in gl_context rather than a subfield of gl_context::TransformFeedback. Note: We can't put RasterDiscard inside gl_context::Transform, since all items inside gl_context::Transform need to be pieces of state that are saved and restored using PushAttrib and PopAttrib.

* mesa: Fix error generation for glClearBuffer{i ui}v with GL_DEPTH or GL_STENCILIan Romanick2011-11-071-0/+84
| | | | | | | | | | | | | | | | | | | | The spec says "Only ClearBufferiv should be used to clear stencil buffers." and "Only ClearBufferfv should be used to clear depth buffers." However, on the following page it also says: "The result of ClearBuffer is undefined if no conversion between the type of the specified value and the type of the buffer being cleared is defined (for example, if ClearBufferiv is called for a fixed- or floating-point buffer, or if ClearBufferfv is called for a signed or unsigned integer buffer). *This is not an error.*" Emphasis mine. Fixes problems with piglit's clearbuffer-invalid-drawbuffer test.

* mesa: Respect GL_RASTERIZER_DISCARD for various meta-type operations.Eric Anholt2011-10-011-5/+11
| | | | | | | | | | | | | | | | From the EXT_transform_feedback spec: Primitives can be optionally discarded before rasterization by calling Enable and Disable with RASTERIZER_DISCARD_EXT. When enabled, primitives are discared right before the rasterization stage, but after the optional transform feedback stage. When disabled, primitives are passed through to the rasterization stage to be processed normally. RASTERIZER_DISCARD_EXT applies to the DrawPixels, CopyPixels, Bitmap, Clear and Accum commands as well. And the GL 3.2 spec says it applies to ClearBuffer* as well.

* mesa: introduce a clear color union to be used for int/unsigned buffersDave Airlie2011-09-141-49/+33
| | | | | | | | | | This introduces a new gl_color_union union and moves the current ClearColorUnclamped to use it, it removes current ClearColor completely and renames CCU to CC, then all drivers are modified to expected unclamped floats instead. also fixes st to use translated color in one place it wasn't.

* mesa: implement GL3 glClearBuffer() functionsBrian Paul2009-12-301-0/+344
| | | | | | | | | | | | These functions clear color/depth/stencil buffers with a value that's passed to the function, rather than the context clear values. For now these functions are implemented in terms of the existing ctx->Driver.Clear() hook. In the future when we have non-normalized integer and unsigned integer color buffer formats we'll need new driver hook(s) to pass int and uint clear values to the driver. Note: these functions are not hooked into the dispatch table at this time.
