I read the following about the /proc/sys/vm/swapctl values:
* If the page was used since the last time we scanned, its age is increased by sc_page_advance (default 3). Where the maximum value is given by sc_max_page_age (default 20).
* Otherwise (meaning it wasn't used) its age is decreased by sc_page_decline (default 1).
How can the intel hardware detect page access if the page is mapped into the process VM(and resident in RAM)? If detecting such access is impossible, then how does kswapd decide the page "age" in this case? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
