>What is the current level of large page support implemented >for Linux ?
Linux currently doesn't support "large" pages ... but it does support "huge" ones. On ia64 there is a kernel compile-time choice for the regular page size between 4k, 8k, 16k and 64k. The default is 16k. Huge page size is selectable via a boot-time parameter "hugepagesz=", choices are just about anything supported by h/w (current implementations of Itanium 2 support even powers of two up to 4G). Default is 256MB. >Can applications specify a certain page-size to use for >their private mappings ? Is this limited to any particular page-size ? No ... normal allocations are done using the default system page size. To see how to use huge pages, read Documentation/vm/hugetlbpage.txt in the Linux kernel sources. >Is smart-demotion implemented ? No. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
