The policy it implements - * is rudimentary and will likely improve over time, but it does work well - * enough today. - * - * Two functionalities are implemented here which both use "control theory" - * (feedback) to optimize memory utilization. In a virtualized environment - * such as Xen, RAM is often a scarce resource and we would like to ensure - * that each of a possibly large number of virtual machines is using RAM - * efficiently, i.e. using as little as possible when under light load - * and obtaining as much as possible when memory demands are high. - * Since RAM needs vary highly dynamically and sometimes dramatically, - * "hysteresis" is used, that is, memory target is determined not just - * on current data but also on past data stored in the system. - * - * "Selfballooning" creates memory pressure by managing the Xen balloon - * driver to decrease and increase available kernel memory, driven - * largely by the target value of "Committed_AS" (see /proc/meminfo). - * Since Committed_AS does not account for clean mapped pages (i.e. pages - * in RAM that are identical to pages on disk), selfballooning has the - * affect of pushing less frequently used clean pagecache pages out of - * kernel RAM and, presumably using cleancache, into Xen tmem where - * Xen can more efficiently optimize RAM utilization for such pages. - * - * When kernel memory demand unexpectedly increases faster than Xen, via - * the selfballoon driver, is able to (or chooses to) provide usable RAM, - * the kernel may invoke swapping. In most cases, frontswap is able - * to absorb this swapping into Xen tmem. However, due to the fact - * that the kernel swap subsystem assumes swapping occurs to a disk, - * swapped pages may sit on the disk for a very long time; even if - * the kernel knows the page will never be used again. This is because - * the disk space costs very little and can be overwritten when - * necessary. When such stale pages are in frontswap, however, they - * are taking up valuable real estate. "Frontswap selfshrinking" works - * to resolve this: When frontswap activity is otherwise stable - * and the guest kernel is not under memory pressure, the "frontswap - * selfshrinking" accounts for this by providing pressure to remove some - * pages from frontswap and return them to kernel memory. - * - * For both "selfballooning" and "frontswap-selfshrinking", a worker - * thread is used and sysfs tunables are provided to adjust the frequency - * and rate of adjustments to achieve the goal, as well as to disable one - * or both functions independently. - * - * While some argue that this functionality can and should be implemented - * in userspace, it has been observed that bad things happen (e.g. OOMs). - * - * System configuration note: Selfballooning should not be enabled on - * systems without a sufficiently large swap device configured; for best - * results, it is recommended that total swap be increased by the size - * of the guest memory. Note, that selfballooning should be disabled by default - * if frontswap is not configured. Similarly selfballooning should be enabled - * by default if frontswap is configured and can be disabled with the - * "tmem.selfballooning=0" kernel boot option. Finally, when frontswap is - * configured, frontswap-selfshrinking can be disabled with the - * "tmem.selfshrink=0" kernel boot option. - * - * Selfballooning is disallowed in domain0 and force-disabled. - * - */ - -#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt - -#include <linux/kernel.h> -#include <linux/memblock.h> -#include <linux/swap.h> -#include <linux/mm.h> -#include <linux/mman.h> -#include <linux/workqueue.h> -#include <linux/device.h> -#include <xen/balloon.h> -#include <xen/tmem.h> -#include <xen/xen.h> - -/* Enable/disable with sysfs. */ -static int xen_selfballooning_enabled __read_mostly; - -/* - * Controls rate at which memory target (this iteration) approaches - * ultimate goal when memory need is increasing (up-hysteresis) or - * decreasing (down-hysteresis).

You can use the name of local variable, local data structure member (e.g. var->field, var.field2), local array with fixed index (e.g. array[1], var->array[0], var->pointer[2]), or kprobe-tracer argument format (e.g. $retval, %ax, etc). Note that the name of this argument will be set as the last member name if you specify a local data structure member (e.g. field2 for 'var->field1.field2'.) '$vars' and '$params' special arguments are also available for NAME, '$vars' is expanded to the local variables (including function parameters) which can access at given probe point. '$params' is expanded to only the function parameters. 'TYPE' casts the type of this argument (optional). If omitted, perf probe automatically set the type based on debuginfo (*). Currently, basic types (u8/u16/u32/u64/s8/s16/s32/s64), hexadecimal integers (x/x8/x16/x32/x64), signedness casting (u/s), "string" and bitfield are supported. (see TYPES for detail) On x86 systems %REG is always the short form of the register: for example %AX. %RAX or %EAX is not valid. +"@user" is a special attribute which means the LOCALVAR will be treated as a user-space memory. This is only valid for kprobe event.
