This version of the patch is pretty close to the _f blend functions in vc4, so it should be at least partially drop-in. I'd love to get the corresponding Panfrost code upstreamed as well, but for $REASONS that probably can't happen yet. > I'm also hoping that at some point I can figure out how to represent > the TLB loads properly in NIR (with respect to multisampling, in > particular) so that we can move the whole blend pipeline up. It's worth noting that for us, because we're in the wacky dedicated shader stage, it's unclear whether that would actually help. I'll need to poke harder, I guess ;) I haven't considered how MSAA interacts with this, ick... _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
