Well done on getting this enabled Out of interest how far is SandyBridge from 3.2?

Since geometry shaders were the last remaining feature needed for GL 3.2, it's time to turn on GL 3.2 support. Here is a short patch series to turn it on. Patch 1 enables GLSL 1.50 and GL 3.2 for i965/gen7 parts (Ivy Bridge and Haswell). Patch 2 removes the old warning message "Geometry shader support is currently experimental". Patch 3 bumps the Mesa major version from 9 to 10 to reflect the fact that we now support a new version of OpenGL. Note: although geometry shaders are feature complete, there are still a few bugs that I still need to iron out before the next release. Here is a list of all the current GLSL 1.50 and GL 3.2 piglit failures on Ivy Bridge and Haswell. With a few minor exceptions that are unfixable due to hardware limitations, or which are too obscure to be worth fixing, I believe I can take care of all of these by the Nov 27 release date. OpenGL 3.2 piglit failures: -------------------------- - layered-rendering/clear-{color,depth}: It appears that our glClear implementation doesn't clear all layers of a layered attachment. - layered-rendering/{framebuffer-layered-attachments,framebuffertexture-defaults}: I have not investigated, but I believe Jordan Justen may be working on this. - minmax: GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS has the wrong value. GLSL 1.50 piglit failures: ------------------------- - built-in constants/* (9 failures) and compiler/constants.geom: a few new GLSL 1.50 built-in constants aren't being set up properly. - compiler/{vs,gs}-redeclares-pervertex-out-{after,after-other,before}-global-redeclaration.geom: We're not flagging an error if both gl_PerVertex and one of its members are redeclared. - compiler/incorrect-{in,out}-layout-qualifiers-with-variable-declarations.geom: We're not flagging an error if GS layout qualifiers are improperly applied to variables. - compiler/interface-blocks-name-reused-globally.vert: We're not flagging an error if an interface block name conflicts with a global variable name. - compiler/interface-blocks-structs-defined-within-block-instanced.vert: We're not flagging an error if a struct is defined inside an interface block. - compiler/layout-fs-no-output.frag: We're not flagging an error if GS layout qualifiers are used in a non-geometry shader. - compiler/layout-not-case-sensitive-{in,max-vert,out}.geom and compiler/layout-not-case-sensitive.frag: Layout qualifiers should be case-insensitive--they are not. - compiler/layout-vs-no-{input,output}.vert: We're not flagging an error if GS layout qualifiers are used in a non-geometry shader. - execution/geometry/clip-distance-bulk-copy: Test is broken. I have a patch on the Piglit list to fix this. - execution/geometry/triangle-strip-orientation (Ivy Bridge only): Vertices in triangle strips are improperly ordered. I am working on a fix for this. - glsl-1.50-geometry-primitive-id-restart GL_POINTS other (Ivy Bridge only): A hardware workaround is required. I am working on a fix for this. - glsl-1.50-geometry-primitive-types * (10 failures): Failing due to bugs in transform feedback (I accidentally dropped a patch from Bryan Cain's original geometry shader series). I am working on a fix for this. - glsl-1.50-geometry-tri-strip-ordering-with-prim-restart * (4 failures): Vertices in triangle strips are improperly ordered. I am working on a fix for this. - linker/interstage-{pervertex,pervertex-in,pervertex-out}-redeclaration-unneeded: We're not accounting for the fact that a compilation unit is not required to redeclare gl_PerVertex if it does not use it. - query-gs-prim-types: New geometry shader informational queries are not implemented yet. [PATCH 1/3] i965: Turn on GLSL 1.50 and GL 3.2 support for i965 gen7. [PATCH 2/3] mesa: Remove warning that geometry shader support is experimental. [PATCH 3/3] mesa: Bump version to 10.0.0. _______________________________________________ mesa-dev mailing list <a href="mailto:mesa-dev@lists.freedesktop.org">mesa-dev@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/mesa-dev" target="_blank">http://lists.freedesktop.org/mailman/listinfo/mesa-dev</a> </blockquote></div>
