[fm-discuss] FMA changes for UltraSPARC I revival

[Rainer Orth]

I've just raised a couple of questions about the proposed UltraSPARC I
revival.  One of the issues affects an FMA header, so Jonathan Adams
suggested to raise it here:

	http://mail.opensolaris.org/pipermail/opensolaris-code/2006-May/000822.html

* When UltraSPARC I support is resurrected, it seems to be correct to
  rename /usr/include/sys/fm/cpu/UltraSPARC-II.h to UltraSPARC.h (or
  UltraSPARC-I.h) since this file already refers to both CPU types.

What do you think about such a change?

Btw., speaking of US-I revival, there has been a question in the past about
proper FMA support for US-I/II CPUs, and Mike Shapiro posted an excellent
overview about what would be required for this:

	http://www.opensolaris.org/jive/thread.jspa?threadID=1427&tstart=0

Is anyone already working on this?  It would be really helpful for revived
US-I support as well.

Regards.
	Rainer
