Eh... build Mesa. Save the libGL and *_dri.so. Apply patch. Build again. Run applications with LD_PRELOAD and LIBGL_DRIVERS_PATH (or EGL_DRIVERS_PATH) set to mix the old and new. > Where is the ABI documented? I don't know this particular code that well, so this may be a non-issue. Generally, any structures that represent data that is accessed in both libGL (or libEGL) and *_dri.so are ABI. Usually these structures are versioned so that fields can be added... you just don't ever get to change or remove fields. The .h file is the documentation. include/GL/internal/dri_interface.h is the prime example _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
