Hello, I sent a patch earlier to add a new PIPE_CAP about disallowing mixed fb cbuf/zsbuf sizes, which would be used to disable ARB_fbo. I think people were generally in favor, but I didn't see any actual Reviewed-By's, I'll resend it with updated nouveau directories (I guess everything got moved for some reason) and help text that more accurately describes the situation.
However, as it turns out, that doesn't go quite far enough. The bpp of cbuf/zsbuf has to match up as well, which apparently can happen even without ARB_fbo. Currently st_validate_framebuffer has special logic to deal with PIPE_CAP_MIXED_COLORBUFFER_FORMATS and return FRAMEBUFFER_UNSUPPORTED as necessary. I was thinking this could be handled by adding a pipe_screen->validate_fb() hook, and folding the MIXED_COLORBUFFER_FORMATS stuff into it (as well as implementing the nv30-specific logic as well). I could alternatively add another PIPE_CAP, but I think it's getting to be too much. Thoughts? Alternate proposals? Thanks for any feedback, -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
