Archives For Mesa PPA

The latest Mesa 3D graphics library 17.1.0, which was released a week ago, now is backported for Ubuntu 16.04 and Ubuntu 17.04 via “Ubuntu-X” team PPA.

Mesa 17.1.0 implements the OpenGL 4.5 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don’t support all the features required in OpenGL 4.5. OpenGL 4.5 is only available if requested at context creation because compatibility contexts are not supported.

Mesa 17.1.0 features:

  • OpenGL 4.2 on i965/ivb
  • GL_ARB_gpu_shader_fp64 on i965/ivybridge
  • GL_ARB_gpu_shader_int64 on i965/gen8+, nvc0, radeonsi, softpipe, llvmpipe
  • GL_ARB_shader_ballot on nvc0, radeonsi
  • GL_ARB_shader_clock on nv50, nvc0, radeonsi
  • GL_ARB_shader_group_vote on radeonsi
  • GL_ARB_shader_precision on i965/ivb
  • GL_ARB_shader_viewport_layer_array on radeonsi
  • GL_ARB_sparse_buffer on radeonsi/CIK+
  • GL_ARB_transform_feedback2 on i965/gen6
  • GL_ARB_transform_feedback_overflow_query on i965/gen6+
  • GL_ARB_vertex_attrib_64bit on i965/ivb
  • GL_NV_fill_rectangle on nvc0
  • Geometry shaders enabled on swr
