Hello,

since there has been a lot of recent activity around the Linux kernel on SPARC
and there are also a lot of issues to be dealt with and unmerged patches, I have
decided to summarize the current state of the Linux kernel on SPARC to bring
anyone interested up to date.



      I want to thank you for the incredible support and work that you do.


You're welcome.


      It seems clear to me that testing anything on old Sun hardware is
      likely a waste of time. That hardware is for a museum or perhaps
      just a recycle pile. Experiments done on such hardware is a waste
      of time regardless if it works or not.


Well, you should at least give me the time to response before you rage-quit ;-).



Nothing quite so dramatic.
Mostly just some mild curseing at my coffee cup.


I have replied to your previous mail and I think the problem is that you just
misconfigured SILO and also made some wrong assumptions on how it works.


      I think a modern server such a the ORACLE S7 is a better direction
      wherein the work done has future value. Even the Fujitsu M4000 type
      machines are getting very long in the tooth.


People have successfully verified the patched kernel on UltraSPARC II machines,
so I think it should work on your machine as well.



I am making progress I think. Thank you. However the point still stands
that these old machines are really not very useful. I will try to get my
hands on something with a lot more modern capability.
