* mesa: Add dd_function_table::PrepareExecBeginChad Versace2011-10-183-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This hook allows the driver to prepare for a glBegin/glEnd. i965 will use the hook to avoid avoid recursive calls to FLUSH_VERTICES during a buffer resolve meta-op. Detailed Justification ---------------------- When vertices are queued during a glBegin/glEnd block, those vertices must of course be drawn before any rendering state changes. To enusure this, Mesa calls FLUSH_VERTICES as a prehook to such state changes. Therefore, FLUSH_VERTICES itself cannot change rendering state without falling into a recursive trap. This precludes meta-ops, namely i965 buffer resolves, from occuring while any vertices are queued. To avoid that situation, i965 must satisfy the following condition: that it queues no vertex if a buffer needs resolving. To satisfy this, i965 will use the PrepareExecBegin hook to resolve all buffers on entering a glBegin/glEnd block. -------- v2: Don't add dd_function_table::CleanupExecEnd. Anholt and I discovered that hook to be unnecessary. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* swrast: Fix fastpaths for glRead/WritePixels(GL_DEPTH_STENCIL)Chad Versace2011-10-182-0/+4
| | | | | | | | | | | | | | | | | | | In some cases, Intel hardware requires that depth and stencil buffers be separate. To accommodate swrast, i965 resorts to hackery that causes a segfault in the fastpaths of draw_depth_stencil_pixels() and read_depth_stencil_pixels(). The hack is that i965 sets framebuffer->Attachment[BUFFER_DEPTH].Renderbuffer and framebuffer->Attachment[BUFFER_STENCIL].Renderbuffer to a dummy renderbuffer for which the GetRow accessors and friends are null. The real buffers are located at framebuffer->_DepthBuffer and framebuffer->_Stencilbuffer. To fix the segault, this patch skips the fastpath if framebuffer->Attachment[BUFFER_DEPTH].Renderbuffer->GetRow is null. Note: This is a candidate for the 7.11 branch.

* meta: Bump MAX_META_OPS_DEPTH from 2 to 8Chad Versace2011-10-181-1/+1
| | | | | | | | | When i965 uses (in the near future) meta-ops to perform buffer resolves, the meta-op stack exceeds depth 2. I bumped it to 8 because... 8 is bigger than 2, but not too big. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* meta: Add flag MESA_META_SELECT_FEEDBACKChad Versace2011-10-182-0/+28
| | | | | | | | | | | If this flag is set, then _mesa_meta_begin/end will save/restore the state of GL_SELECT and GL_FEEDBACK render modes. Intel's future buffer resolve meta-ops will require this, since buffer resolves may occur when the GL_RENDER_MODE is GL_SELECT.

* intel: Convert from GLboolean to 'bool' from stdbool.h.Kenneth Graunke2011-10-1889-732/+738
| | | | | | | | | | | | | | | | | I initially produced the patch using this bash command: for file in {intel,i915,i965}/*.{c,cpp,h}; do [ ! -h $file ] && sed -i 's/GLboolean/bool/g' $file && sed -i 's/GL_TRUE/true/g' $file && sed -i 's/GL_FALSE/false/g' $file; done Then I manually added #include <stdbool.h> to fix compilation errors, and converted a few functions back to GLboolean that were used in core Mesa's function pointer table to avoid "incompatible pointer" warnings. Finally, I cleaned up some whitespace issues introduced by the change.

* meta: Fix saving the active programNeil Roberts2011-10-181-1/+1
| | | | | | | | | | When saving the active program in _mesa_meta_begin, it was actually saving the fragment program instead. This means that if the application binds a program that only has a vertex shader then when the meta saved state is restored it will forget the bound program.

* mesa: Convert fixed function fragment program generator to GLSL IR.Eric Anholt2011-10-184-754/+688
| | | | | | | | This is a step towards providing a direct route for drivers accepting GLSL IR for codegen. Perhaps more importantly, it runs the fixed function fragment program through the GLSL IR optimization. Having seen how easy it is to make ugly fixed function texenv code that can do unnecessary work, this may improve real applicatinos.
* mesa: Add a flag for shader programs to allow SSO linkage in GLES2.Eric Anholt2011-10-182-1/+13
| | | | | | | | On converting fixed function programs to generate GLSL, the linker became cranky that we were trying to make something that wasn't a linked vertex+fragment program. Given that the Mesa GLES2 drivers also support desktop GL with EXT_sso, just telling the linker to shut up seems like the easiest solution.

| | | | | | | | | | | | | | | | | | | | For glReadPixels, the user supplied pixels have format GL_UNSIGNED_INT_24_8. But, when the depthstencil buffer's format was MESA_FORMAT_S8_Z24, the fastpath read from the buffer without reordering the depth and stencil bits. To fix this, this patch just skips the fastpath when the format is not MESA_FORMAT_Z24_S8. The problem and fix for glWritePixels is analagous.

The last part of the implementation of ArrayElement is: if (generic attribute array 0 enabled) { if (generic vertex attribute 0 array normalization flag is set, and type is not FLOAT or DOUBLE) VertexAttrib[size]N[type]v(0, generic vertex attribute 0 array element i); else VertexAttrib[size][type]v(0, generic vertex attribute 0 array element i); } else if (vertex array enabled) { Vertex[size][type]v(vertex array element i); } Page 23 (page 37 of the PDF) of the same spec says: "Setting generic vertex attribute zero specifies a vertex; the four vertex coordinates are taken from the values of attribute zero. A Vertex2, Vertex3, or Vertex4 command is completely equivalent to the corresponding VertexAttrib* command with an index of zero." Fixes piglit test attribute0.
