It looks like POWER Linux systems have differences in /sys as compared
to AMD / Intel systems. Attached is a tarball from a SLES9/SP3
machine that had its kernel upgraded to a kernel.org 2.6.18.1. The
machine has 4 sockets, each with 2 SMT threads and 1 core.
PLPA is currently looking for the following files:
/sys/devices/system/cpu/cpuX/online
core_id
physical_package_id
But this POWER /sys filesystem doesn't have core_id or
physical_package_id. Instead, it has "physical_id". I notice that
there's also a "topology" directory under .../cpu/cpuX, but it's empty.
Are there any POWER experts out there?
More specifically, it looks like different chips have different things
in /sys. Ugh. Is there a way that PLPA can at least determine
whether it's on a sys that it understands?
