It is basically non-pageable (permanent) memory, including OpenBoot PROM (OBP) and kernel memory. To remove permanent memory from the system, we have to go through a so-called "copy-rename" process to copy the content of the permanent memory to another range of memory, then change their virtual address. To support Dynamic Reconfiguration (DR), we try to keep all the permanent memory on one board to minimize the need for "copy-rename". Hope that helps. :) Sherry -- [EMAIL PROTECTED], Solaris Kernel Development, http://blogs.sun.com/sherrym _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
