1 2Status of OpenGL 3.x features in Mesa 3 4 5Note: when an item is marked as "DONE" it means all the core Mesa 6infrastructure is complete but it may be the case that few (if any) drivers 7implement the features. 8 9 10Feature Status 11----------------------------------------------------- ------------------------ 12 13GL 3.0: 14 15GLSL 1.30 (GL_EXT_gpu_shader4, etc.) started 16glBindFragDataLocation, glGetFragDataLocation not started 17Conditional rendering (GL_NV_conditional_render) DONE (swrast, softpipe, i965) 18Map buffer subranges (GL_ARB_map_buffer_range) DONE 19Clamping controls (GL_ARB_color_buffer_float) DONE 20Float textures, renderbuffers (GL_ARB_texture_float) DONE (gallium r300) 21GL_EXT_packed_float DONE (gallium r600) 22GL_EXT_texture_shared_exponent DONE (gallium, swrast) 23Float depth buffers (GL_ARB_depth_buffer_float) DONE 24Framebuffer objects (GL_EXT_framebuffer_object) DONE 25Half-float DONE 26Multisample blit DONE 27Non-normalized Integer texture/framebuffer formats ~50% done 281D/2D Texture arrays DONE (gallium, swrast) 29Packed depth/stencil formats DONE 30Per-buffer blend and masks (GL_EXT_draw_buffers2) DONE 31GL_EXT_texture_compression_rgtc DONE (swrast, gallium r600) 32Red and red/green texture formats DONE (swrast, i965, gallium) 33Transform feedback (GL_EXT_transform_feedback) ~50% done 34Vertex array objects (GL_APPLE_vertex_array_object) DONE 35sRGB framebuffer format (GL_EXT_framebuffer_sRGB) core GL done (i965, gallium), GLX todo 36glClearBuffer commands DONE 37glGetStringi command DONE 38glTexParameterI, glGetTexParameterI commands DONE 39glVertexAttribI commands DONE (but converts int 40 values to floats) 41Depth format cube textures not started 42GLX_ARB_create_context (GLX 1.4 is required) not started 43 44 45GL 3.1: 46 47GLSL 1.40 not started 48Instanced drawing (GL_ARB_draw_instanced) DONE (gallium, swrast) 49Buffer copying (GL_ARB_copy_buffer) DONE 50Primitive restart (GL_NV_primitive_restart) DONE (gallium) 5116 vertex texture image units DONE 52Texture buffer objs (GL_ARB_texture_buffer_object) not started 53Rectangular textures (GL_ARB_texture_rectangle) DONE 54Uniform buffer objs (GL_ARB_uniform_buffer_object) not started 55Signed normalized textures (GL_EXT_texture_snorm) DONE (gallium) 56 57 58GL 3.2: 59 60Core/compatibility profiles not started 61GLSL 1.50 not started 62Geometry shaders (GL_ARB_geometry_shader4) partially done (Zack) 63BGRA vertex order (GL_ARB_vertex_array_bgra) DONE 64Base vertex offset(GL_ARB_draw_elements_base_vertex) DONE 65Frag shader coord (GL_ARB_fragment_coord_conventions) DONE (swrast, gallium) 66Provoking vertex (GL_ARB_provoking_vertex) DONE 67Seamless cubemaps (GL_ARB_seamless_cube_map) DONE 68Multisample textures (GL_ARB_texture_multisample) not started 69Frag depth clamp (GL_ARB_depth_clamp) DONE 70Fence objects (GL_ARB_sync) DONE 71GLX_ARB_create_context_profile not started 72 73 74GL 3.3: 75 76GLSL 3.30 not started 77GL_ARB_blend_func_extended not started 78GL_ARB_explicit_attrib_location DONE (swrast, i915, i965) 79GL_ARB_occlusion_query2 DONE (swrast, gallium) 80GL_ARB_sampler_objects DONE (gallium) 81GL_ARB_texture_rgb10_a2ui not started 82GL_ARB_texture_swizzle DONE (same as EXT version) 83GL_ARB_timer_query ~60% done (the EXT variant) 84GL_ARB_instanced_arrays DONE (gallium) 85GL_ARB_vertex_type_2_10_10_10_rev DONE (gallium) 86 87 88GL 4.0: 89 90GLSL 4.0 not started 91GL_ARB_texture_query_lod not started 92GL_ARB_draw_buffers_blend DONE (gallium softpipe) 93GL_ARB_draw_indirect not started 94GL_ARB_gpu_shader_fp64 not started 95GL_ARB_sample_shading not started 96GL_ARB_shader_subroutine not started 97GL_ARB_tessellation_shader not started 98GL_ARB_texture_buffer_object_rgb32 not started 99GL_ARB_texture_cube_map_array not started 100GL_ARB_texture_gather not started 101GL_ARB_transform_feedback2 started 102GL_ARB_transform_feedback3 not started 103 104 105GL 4.1: 106 107GLSL 4.1 not started 108GL_ARB_ES2_compatibility DONE (i965) 109GL_ARB_get_program_binary not started 110GL_ARB_separate_shader_objects some infrastructure done 111GL_ARB_shader_precision not started 112GL_ARB_vertex_attrib_64bit not started 113GL_ARB_viewport_array not started 114 115 116GL 4.2: 117GLSL 4.2 not started 118GL_ARB_texture_compression_bptc not started 119GL_ARB_compressed_texture_pixel_storage not started 120GL_ARB_shader_atomic_counters not started 121GL_ARB_texture_storage DONE (gallium, swrast) 122GL_ARB_transform_feedback_instanced not started 123GL_ARB_base_instance not started 124GL_ARB_shader_image_load_store not started 125GL_ARB_conservative_depth DONE (compiler) 126GL_ARB_shading_language_420pack not started 127GL_ARB_internalformat_query not started 128GL_ARB_map_buffer_alignment not started 129 130 131More info about these features and the work involved can be found at 132http://dri.freedesktop.org/wiki/MissingFunctionality 133
