[Mesa3d-dev] Remove static_dispatch=false from GL functions exported by ATI or nVidia?
Currently, there are several functions where static dispatch has been disabled, but that are exported by either ATI, nVidia or both lib. To prevent compatibility issues, it seems a good idea to export those too at least. What do you think? Should we export all function exported by both nVidia and ATI, those exported by any of them, or even just export all functions? static_dispatch=false but exported by both ATI and nVidia: glBlendEquationSeparateEXT glBlitFramebufferEXT glGetQueryObjecti64vEXT glGetQueryObjectui64vEXT glProgramEnvParameters4fvEXT glProgramLocalParameters4fvEXT static_dispatch=false but exported by ATI, not by nVidia: glGetHistogramEXT glGetHistogramParameterfvEXT glGetHistogramParameterivEXT glGetMinmaxEXT glGetMinmaxParameterfvEXT glGetMinmaxParameterivEXT glGetTexParameterPointervAPPLE glHistogramEXT glMinmaxEXT glResetHistogramEXT glResetMinmaxEXT glStencilFuncSeparateATI glStencilOpSeparateATI glTextureRangeAPPLE static_dispatch=false but exported by nVidia, not by ATI: glActiveStencilFaceEXT glColorSubTableEXT glDeleteFencesNV glDepthBoundsEXT glFinishFenceNV glGenFencesNV glGetFenceivNV glIsFenceNV glSetFenceNV glTestFenceNV -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Mesa3d-dev mailing list Mesa3d-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mesa3d-dev

No. The libGL ABI is well defined: http://www.opengl.org/registry/ABI/ -- Earthling Michel Dänzer |http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Mesa3d-dev mailing list Mesa3d-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mesa3d-dev

No. The libGL ABI is well defined: http://www.opengl.org/registry/ABI/ Does the ABI forbid exporting additional functions from libGL.so? As far as I can tell, it doesn't, and only says what is required to be exported, and that applications shouldn't statically link to other functions. The way things are now, some applications that work with nVidia or ATI implementations will fail to link or fail to load with Mesa, which seems undesirable. A bug on this has just been reported. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Mesa3d-dev mailing list Mesa3d-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mesa3d-dev

As far as I can tell, it doesn't, Of course it doesn't, but what's the point? They can't be relied on anyway. and only says what is required to be exported, and that applications shouldn't statically link to other functions. The way things are now, some applications that work with nVidia or ATI implementations will fail to link or fail to load with Mesa, which seems undesirable. Applications relying on things not guaranteed by the ABI are broken. A bug on this has just been reported. Sounds like not our bug. -- Earthling Michel Dänzer |http://www.vmware.com Libre software enthusiast | Debian, X and DRI developer -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Mesa3d-dev mailing list Mesa3d-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mesa3d-dev
