It doesn't have to be. Book3 2.02 says: "Read access to the PIR is privileged; write access, if provided, is described in the Book IV, PowerPC Implementation Features document for the implementation". In other words, it's up to the implemenation if it's writable or not, and how it's writable: Chip in init scans, mtspr or other ways. -Olof _______________________________________________ Xen-ppc-devel mailing list Xenfirstname.lastname@example.org http://lists.xensource.com/xen-ppc-devel
