We can force any MMIO accesses to any rope with "Directed Ranges" on Astro. We can NOT force IO Port accesses to anything. > If it's feasible, I'm willing to take some time to look into this. I'm not sure it's "feasible" unless we can get around IO Port space routing issues. grant > > Cheers, > -- > Kyle McMartin _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
