* i965: Set up clip distance VUE slots appropriately for gl_ClipDistance.Paul Berry2011-09-234-27/+32
| | | | | | | | | | | | | | | When gl_ClipDistance is in use, the contents of the gl_ClipDistance array just need to be copied directly into the clip distance VUE slots, so we re-use the code that copies all other generic VUE slots (this has been extracted to its own method). When gl_ClipDistance is not in use, the vertex shader needs to calculate the clip distances based on user-specified clipping planes. This patch also removes the i965-specific enum values BRW_VERT_RESULT_CLIP[01], since we now have generic Mesa enums that serve the same purpose (VERT_RESULT_CLIP_DIST[01]).

* i965: Don't upload clip planes when gl_ClipDistance is in use.Paul Berry2011-09-234-7/+12
| | | | | | | | When the vertex shader writes to gl_ClipDistance, we do clipping based on clip distances rather than user clip planes, so don't waste push constant space storing user clip planes that won't be used. Reviewed-by: Eric Anholt <[email protected]>
* i965: Enable lower_clip_distance.Paul Berry2011-09-231-0/+1
| | | | | | | | i965 requires gl_ClipDistance to be formatted as an array of 2 vec4's (as opposed to an array of 8 floats), so enable the lowering pass that performs this conversion. Reviewed-by: Eric Anholt <[email protected]>
* mesa: Decode GL_CLIP_DISTANCE[67] properly in _mesa_set_enable().Paul Berry2011-09-231-6/+8
| | | | | | | | | | | | | In order to support 8 clip distances, we need to properly decode when the user sets the GL_CLIP_DISTANCE6 and GL_CLIP_DISTANCE7 enable flags. For clarity, this patch changes the names GL_CLIP_PLANE[0-5] in the switch statement to the equivalent names GL_CLIP_DISTANCE[0-5], since the GL_CLIP_PLANE names are deprecated.

* mesa: set up gl_vert_result and gl_frag_attrib values for gl_ClipDistance.Paul Berry2011-09-232-10/+14
| | | | | | | | | | | | This patch assigns enumerated values for gl_ClipDistance in the gl_vert_result and gl_frag_attrib enums, so that driver back-ends can assign gl_ClipDistance to the appropriate hardware registers. It also adjusts the functions _mesa_vert_result_to_frag_attrib() and _mesa_frag_attrib_to_vert_result() (which translate between the two enums) to correctly translate the new enumerated values.

* mesa: Add a flag to indicate whether a program uses gl_ClipDistance.Paul Berry2011-09-233-1/+12
| | | | | | | | | | | | | | | | | | GLSL 1.30 requires us to use gl_ClipDistance for clipping if the vertex shader contains a static write to it, and otherwise use user-defined clipping planes. Since the driver needs to behave differently in these two cases, we need a flag to record whether the shader has written to gl_ClipDistance. The new flag is called UsesClipDistance. We initially store it in gl_shader_program (since that is the data structure that is available when we check to see whethe gl_ClipDistance was written to), and we later copy it to a flag with the same name in gl_vertex_program, since that is a more convenient place for the driver to access it (in i965, at least).

* glsl: Implement a lowering pass for gl_ClipDistance.Paul Berry2011-09-236-0/+351
| | | | | | | | | | | | | | | | | | | In i965 GEN6+ (and I suspect most other hardware), gl_ClipDistance needs to be laid out as a pair of vec4's (the first containing clip distances 0-3, and the second containing clip distances 4-7). However, it is declared in GLSL as an array of 8 floats. This lowering pass acts at the GLSL level, modifying the declaration of gl_ClipDistance so that it is an array of vec4's rather than an array of floats, and renaming it to gl_ClipDistanceMESA. In addition, it modifies all accesses to the array so that they access the appropiate component of one of the vec4's. Since some hardware may not internally represent gl_ClipDistance as a pair of vec4's, this lowering pass is optional. To enable it, set the LowerClipDistance flag in gl_shader_compiler_options to true. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl hierarchical visitor: Do not overwrite base_ir for parameter lists.Paul Berry2011-09-232-7/+17
| | | | | | | | | | | | | | This patch fixes a bug in ir_hirearchical_visitor: when traversing an exec_list representing the formal or actual parameters of a function, it modified base_ir to point to each parameter in turn, rather than leaving it as a pointer to the enclosing statement. This was a problem, since base_ir is used by visitor classes to locate the statement containing the node being visited (usually so that additional statements can be inserted before or after it). Without this fix, visitors might attempt to insert statements into parameter lists. Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | There were notes about the possibility of slowdowns due to zcopy from a PBO due to thrashing around of the region. Slowdowns are even more likely now that textures are generally tiled, which a zcopy wouldn't get. Additionally, there were no checks on the buffer size to ensure that the hardware-required rounding was present, which could result in GPU hangs on large zcopy PBOs.
