* swrast: remove calls to _swrast_update_depth/stencil_buffer()Brian Paul2012-01-061-23/+0
| | | | | | | These functions updated the gl_renderbuffer::_DepthBuffer and _StencilBuffer fields. But those fields are no longer used. Reviewed-by: Eric Anholt <[email protected]>
* i965: Turn on ARB_depth_buffer_float by default.Eric Anholt2012-01-061-2/+1
| | | | | | | | | | Everything about this that we have tests for works except for the deprecated metaops. The conclusion we came to on IRC sounded like we were OK with turning it on as long as core functionality works. The remaining failures (copypixels, drawpixels) should just be a matter of finishing the MapRenderbuffer for them. Reviewed-by: Kenneth Graunke <[email protected]>

* mesa: Fix transform feedback of unsubscripted arrays.Paul Berry2012-01-051-45/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not explicitly stated in the GL 3.0 spec that transform feedback can be performed on a whole varying array (without supplying a subscript). However, it seems clear from context that this was the intent. Section 2.15 (TransformFeedback) says this: When writing varying variables that are arrays, individual array elements are written in order. And section 2.20.3 (Shader Variables), says this, in the description of GetTransformFeedbackVarying: For the selected varying variable, its type is returned into type. The size of the varying is returned into size. The value in size is in units of the type returned in type. If it were not possible to perform transform feedback on an unsubscripted array, the returned size would always be 1. This patch fixes the linker so that transform feedback on an unsubscripted array is supported. Fixes piglit tests "EXT_transform_feedback/builtin-varyings gl_ClipDistance[{4,8}]-no-subscript" and "EXT_transform_feedback/output_type *[2]-no-subscript". Note: on back-ends that set gl_shader_compiler_options::LowerClipDistance (for example i965), tests "EXT_transform_feedback/builtin-varyings gl_ClipDistance[{1,2,3,5,6,7}]" still fail. I hope to address this in a later patch. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* mesa: Avoid segfault when getting an unbound transform feedback buffer name.Paul Berry2012-01-051-1/+1
| | | | | | | | | | | | | | | | | | | | Previously we were using gl_transform_feedback_object::Buffers[i]->Name to service an indexed get request for GL_TRANSFORM_FEEDBACK_BUFFER_BINDING. However, if no buffer has been bound, gl_transform_feedback_object::Buffers[i] is NULL, so this was causing a segfault. This patch switches to using gl_transform_feedback_object::BufferNames[i], which is equal to gl_transform_feedback_object::Buffers[i]->Name if gl_transform_feedback_object::Buffers[i] is not NULL, and 0 if it is NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using transform feedback, there are three circumstances in which it is useful for Mesa to instruct a driver to stream out just a portion of a varying slot (rather than the whole vec4): (a) When a varying is smaller than a vec4, Mesa needs to instruct the driver to stream out just the first one, two, or three components of the varying slot. (b) In the future, when we implement varying packing, some varyings will be offset within the vec4, so Mesa will have to instruct the driver to stream out an arbitrary contiguous subset of the components of the varying slot (e.g. .yzw or .yz). (c) On drivers that set gl_shader_compiler_options::LowerClipDistance, if the client requests that an element of gl_ClipDistance be streamed out using transform feedback, Mesa will have to instruct the driver to stream out a single component of one of the gl_ClipDistance varying slots. Previous to this patch, only (a) was possible, since gl_transform_feedback_info specified only the number of components of the varying slot to stream out. This patch adds gl_transform_feedback_info::ComponentOffset, which indicates which components should be streamed out. Reviewed-by: Kenneth Graunke <[email protected]>
* i965: Fix transform feedback of gl_ClipVertex.Paul Berry2012-01-051-5/+8
| | | | | | | | | | | | | | | | | | | | | | | Previously, on i965 Gen6 and above, we weren't allocating space for gl_ClipVertex in the VUE, since the VS was automatically converting it to clip distances. This prevented transform feedback from being able to capture gl_ClipVertex. This patch goes aheads and allocates space for gl_ClipVertex in the VUE on Gen6 and above. The old behavior is retained on Gen5 and below, since (a) transform feedback is not yet supported on those platforms, and (b) those platforms don't currently support gl_ClipVertex anyhow. Note: this constitutes a slight waste of VUE space for shaders that use gl_ClipVertex and don't use transform feedback to capture it. However, that seems preferable to making the VUE map (and all of the state that depends on it) dependent on transform feedback settings.

* i965: Fix transform feedback of gl_PointSize.Paul Berry2012-01-052-2/+14
| | | | | | | | | | | | | | | On i965 Gen6 and above, gl_PointSize is stored in component W of the first VUE slot (which corresponds to VERT_RESULT_PSIZ in the VUE map). Normally we store varying floats in component X of a VUE slot, so we need special case logic for gl_PointSize. For Gen6, we do this with a ".wwww" swizzle in the GS. For Gen7, we shift the component mask by 3 to select the W component. Fixes Piglit test "EXT_transform_feedback/builtin-varyings gl_PointSize". Reviewed-by: Kenneth Graunke <[email protected]>
