------------------------------ Package information for PCSX2 ------------------------------ * The reasons given by upstream as to why they remove -fPIC are the following: - Code only supports the i386 architecture. - Code uses the ebx register and this is not compliant with -fPIC. - The use of -fPIC negatively impacts the performance of the program. - The .so file are not shared libraries but plug-ins. No program should try to link with them. ------------------------------------------ Information about the plug-ins for video ------------------------------------------ * The zzogl plug-in comes in two flavors: - The Nvidia Cg version which requires the non-free nvidia-cg-toolkit package. Since this package contains GPL-2+ code this plug-in can't be distributed without an GPL exception allowing linking with non-free libraries. If the user desires to try this flavor of the plug-in he/she must: + Install the nvidia-cg-dev or nvidia-cg-toolkit package from non-free. + Pass "-DGLSL_API=FALSE" to dh_auto_configure in the rules file. + Add "usr/lib/*/games/pcsx2/*.dat /usr/share/games/pcsx2/" to the install file. + Compile the program using dpkg-buildpackage. This plug-in currently provides the greatest compatibility with video cards and drivers. It currently works with open source drivers like radeon R600. - The OpenGL Shading Language (GLSL) version which currently only works with AMD video cards but support for other cards is being worked on. * The GSdx plug-in currently only supports the OpenGL software renderer. * The GSdx and zzogl GLSL plug-ins currently require a video card that supports at least OpenGL 3.0. A noninclusive list of cards that support OpenGL 3.0 is: - Radeon HD series (except HD2300) - GeForce 8, 9, 100-series, 200-series, 300-series, 400-series and 500-series - Intel Sandy Bridge HD Graphics 2000 and up * Currently the proprietary drivers for AMD and Nvidia have support for OpenGL 3.0 and above. The GSdx and/or zzogl GLSL plug-ins use the following extensions/commands that may or may not be completely implemented in the open source video stack: - OpenGL 3.0 (supported on Mesa 9.2) + glClearBuffer + glGetStringi + glVertexAttribI + GLX_ARB_create_context + GL_ARB_vertex_array_object + GL_ARB_framebuffer_object - OpenGL 3.1 (supported on Mesa 9.2) + GL_ARB_texture_rectangle (zzogl) + GL_ARB_uniform_buffer_object - OpenGL 3.2 + GL_ARB_geometry_shader4 + GL_ARB_draw_elements_base_vertex (GSdx) + GLX_ARB_create_context_profile + GLSL 150 - OpenGL 3.3 (supported on Mesa 9.2) + GL_ARB_blend_func_extended (GSdx) + GL_ARB_explicit_attrib_location + GL_ARB_sampler_objects (GSdx) - OpenGL 4.0 + GL_ARB_GPU_shader5 (GSdx, improve FXAA, optional) - OpenGL 4.1 + GL_ARB_separate_shader_objects - OpenGL 4.2 + GL_ARB_map_buffer_alignment + GL_ARB_shading_language_420pack + GL_ARB_texture_storage - OpenGL 4.3 + GL_ARB_copy_image (GSdx, optional) The current status for the open source drivers can be found at: - http://cgit.freedesktop.org/mesa/mesa/tree/docs/GL3.txt
