Re: 601 vs PowerPC for NetBSD

[Andrew Cagney <cagney%tpgi.com.au@localhost>]

Hello,

I'll dare to make the following synopsis of the descussion (adding my on
opinions):

        o       The 601 included, at the user level
                a number of POWER compatible
                registers and instructions.

                Since NetBSD is a new port and does
                not use any of these features there is
                need to be concerned by this.
                (Unless of course you are foolish
                enough to attempt AIX compatibility :-)


        o       The 601 timer

                Yep that would be a problem but only a
                minor one.


        o       The 601 vm and cache

                The VM  and a few
                other querks could produce a few
                problems.  However the underlying
                VM architecture is still fairly close.

        enjoy,
                Andrew
