------------------------------
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)
