My sponsor request for
6414867 Revive UltraSPARC I support
http://www.opensolaris.org/jive/thread.jspa?threadID=8028&tstart=0
hasn't yet triggered any response, but since there are a couple of open
questions, I'd like to raise them here:
* Until US-I support was removed, you had to force 64-bit support on in
/platform/sun4u/boot.conf. The question is: should ufsboot/inetboot warn
in some way if booted on US-I or just continue?
* 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.
* uts/common/krtld/kobj.c forcibly handles all US-I and US-II CPUs as US-II.
This change is inappropriate when US-I CPUs are supported again. I
haven't found how this was done in the Solaris 9 sources (if at all) and
what the real problems is, do I don't know how to handle this.
Can someone with access to the pre-OpenSolaris sources (i.e. between S9 FCS
and the June 2005 snv build) comment?
Thanks.
Rainer
