I've been meaning to take a look at the NIR->TGSI pass and see if there's an easy way to hook it up to the radeon drivers, but I wanted to be able to get shader-db up and running on that hardware first so that we could get some before/after numbers (I'm assuming that R600 w/o SB will be the main radeon driver that benefits, but I'd love to be proven wrong). --Aaron > --Jason > > > - Bruno > > > >> --Jason > >> _______________________________________________ > >> mesa-dev mailing list > >> mesa-dev@lists.freedesktop.org > >> http://lists.freedesktop.org/mailman/listinfo/mesa-dev > > > > > _______________________________________________ > mesa-dev mailing list > mesa-dev@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/mesa-dev >
