[Disclaimer: I have very limited experience with this, but hope some hint is better than none.] The software renderers obviously output to internal system memory buffers. You need to pick a mechanism to blit those bits to your own output buffer for scanout (or otherwise display). As one example, look at the X server's glx/glxdriswrast.c:__glXDRIscreenProbe() where you can trace down how the DRI mechanism connects swrast output images to X drawable memory. (It is quite convoluted, likely there are better examples than that mechanism, but I don't know them.) -Nathan _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
