* mesa: fix image unpacking when storing compressed texturesBrian Paul2011-10-072-6/+19
| | | | | | | | | | | | | | This fixes failures found with the new piglit texsubimage test. Two things were broken: 1. The dxt code doesn't handle sources images where width != row stride. Check for that and take the _mesa_make_temp_ubyte_image() path to get an image where width = rowstride. 2. If we don't take the _mesa_make_temp_ubyte_image() path we need to take the source image unpacking parameters into account in order to get the proper starting memory address of the source texels. Note: This is a candidate for the 7.11 branch.
* mesa: Create _mesa_bitcount_64() to replace i965's brw_count_bits()Paul Berry2011-10-062-0/+16
| | | | | | | | | | | | | | | | The i965 driver already had a function to count bits in a 64-bit uint (brw_count_bits()), but it was buggy (it only counted the bottom 32 bits) and it was clumsy (it had a strange and broken fallback for non-GCC-like compilers, which fortunately was never used). Since Mesa already has a _mesa_bitcount() function, it seems better to just create a _mesa_bitcount_64() function rather than special-case this in the i965 driver. This patch creates the new _mesa_bitcount_64() function and rewrites all of the old brw_count_bits() calls to refer to it.

* mesa/es: Allow GL_CLIP_PLANE0+6 and GL_CLIP_PLANE0+7.Kenneth Graunke2011-10-061-8/+6
| | | | | | | | | | Fixes the ES1 conformance 'userclip' test, which broke when we increased MAX_CLIP_PLANES to 8. Core Mesa already validates incoming values against MAX_CLIP_PLANES; we just need the ES wrapper to pass everything through.

| | | | | | | | | | It's required for ES 1.0 and 1.1, and isn't specified for ES 2. While the comment says Mesa depends on it internally, removing it from ES2 doesn't seem to regress any Piglit or ES2 conformance tests.

This is a step toward getting rid of the gl_texture_image::ImageOffsets field. Reviewed-by: Eric Anholt <[email protected]>
* i965 Gen6: Implement gl_ClipVertex.Paul Berry2011-10-051-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements proper support for gl_ClipVertex by causing the new VS backend to populate the clip distance VUE slots using VERT_RESULT_CLIP_VERTEX when appropriate, and by using the untransformed clip planes in ctx->Transform.EyeUserPlane rather than the transformed clip planes in ctx->Transform._ClipUserPlane when a GLSL-based vertex shader is in use. When not using a GLSL-based vertex shader, we use ctx->Transform._ClipUserPlane (which is what we used prior to this patch). This ensures that clipping is still performed correctly for fixed function and ARB vertex programs. A new function, brw_select_clip_planes() is used to determine whether to use _ClipUserPlane or EyeUserPlane, so that the logic for making this decision is shared between the new and old vertex shaders. Fixes the following Piglit tests on i965 Gen6: - vs-clip-vertex-const-accept - vs-clip-vertex-const-reject - vs-clip-vertex-different-from-position - vs-clip-vertex-equal-to-position - vs-clip-vertex-homogeneity - vs-clip-based-on-position - vs-clip-based-on-position-homogeneity - clip-plane-transformation clipvert_pos - clip-plane-transformation pos_clipvert - clip-plane-transformation pos Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Chad Versace <[email protected]>
* mesa: Add a gl_vert_result for gl_ClipVertex.Paul Berry2011-10-051-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, clip planes didn't work properly in Mesa when using vertex shaders, because Mesa assigned both gl_ClipVertex and gl_Position to the same gl_vert_result (VERT_RESULT_HPOS). As a result, backends couldn't distinguish between the two variables, so any shader that wrote different values to them would fail to work properly. This patch paves the way for proper support of gl_ClipVertex by creating a new enumerated value in gl_vert_result for it (VERT_RESULT_CLIP_VERTEX). After this patch, a back-end may add support for gl_ClipVertex using the following algorithm: - If using a user-supplied GLSL vertex shader: - If the bit corresponding to VERT_RESULT_CLIP_VERTEX is set in gl_program::OutputsWritten: - Clip using the vertex shader output VERT_RESULT_CLIP_VERTEX and the clip planes defined in gl_context::Transform.EyeUserPlane. - Else: - Clip using the vertex shader output VERT_RESULT_HPOS and the clip planes defined in gl_context::Transform.EyeUserPlane. - Else (either using fixed function or an ARB vertex program): - Clip using the vertex shader output VERT_RESULT_HPOS and the clip planes defined in gl_context::Transform._ClipUserPlane (*) where (*) represents the normal Mesa behavior before this patch. An example of implementing the above algorithm can be found in the patch that follows this one, which implements gl_ClipVertex in i965 Gen6. Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | | | | | | From the EXT_transform_feedback spec: Primitives can be optionally discarded before rasterization by calling Enable and Disable with RASTERIZER_DISCARD_EXT.

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.
