Thanks that explains why kernel and utilities such as prtdiag seem to work fine.
$ ldd /usr/sbin/prtdiag
libsmbios.so.1 =>/usr/lib/libsmbios.so.1
I suppose fixing DDU is low priority, I can certainly live with empty CPU info
in DDU.
A nice project could indeed be modifying dmi_info to use libsmbios.
$ pkg search prtdiag
INDEX ACTION VALUEPACKAGE
basename file usr/sbin/prtdiag pkg:/SUNWcs@0.5.11-2020.0.1.20570
Perhaps SUNWcs core system (Core Solaris) could deliver dmi_info ?
The DDU gui is nice and I was wondering where it gets its info from.
Thanks,
David Stes
