Is the following a snv_19 bug or a feature:
pci devices that are *not* configured by the system's bios (esp. when the
bios runs in "PnP OS = YES" mode), but are configured by the snv_19 kernel
don't appear in the prom node tree printed by "prtconf -p" ; they are
included in the standard device tree only, which is printed by "prtconf".
pci devices configured by the system's bios are included both in the
"prtconf -p" and the "prtconf" device tree.
This is a change from previous Solaris releases upto s10 x86, where
"prtconf -p" was a reliable way to list all pci devices installed in a system.
With snv_19, you now have to use "prtconf" without the "-p" option to
list all pci devices available in a system.
Example: ASUS A7V mainboard, snv_19, with bios set to "PnP OS = YES":
there are 9 top level pci nodes in prom tree, 14 top level pci device nodes
in standard device tree (see the attached files).
