Copyright (C) 2011-2012 Nai Xia -+ * -+ * This is an improvement upon KSM. Some basic data structures and routines -+ * are borrowed from ksm.c . -+ * -+ * Its new features: -+ * 1. Full system scan: -+ * It automatically scans all user processes' anonymous VMAs. Kernel-user -+ * interaction to submit a memory area to KSM is no longer needed. -+ * -+ * 2. Rich area detection: -+ * It automatically detects rich areas containing abundant duplicated -+ * pages based. Rich areas are given a full scan speed. Poor areas are -+ * sampled at a reasonable speed with very low CPU consumption. -+ * -+ * 3. Ultra Per-page scan speed improvement: -+ * A new hash algorithm is proposed. As a result, on a machine with -+ * Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it -+ * can scan memory areas that does not contain duplicated pages at speed of -+ * 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of -+ * 477MB/sec ~ 923MB/sec. -+ * -+ * 4. Thrashing area avoidance: -+ * Thrashing area(an VMA that has frequent Ksm page break-out) can be -+ * filtered out. My benchmark shows it's more efficient than KSM's per-page -+ * hash value based volatile page detection. -+ * -+ * -+ * 5. Misc changes upon KSM: -+ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page -+ * comparison. It's much faster than default C version on x86. -+ * * rmap_item now has an struct *page member to loosely cache a -+ * address-->page mapping, which reduces too much time-costly -+ * follow_page(). -+ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. -+ * * try_to_merge_two_pages() now can revert a pte if it fails. No break_ -+ * ksm is needed for this case. -+ * -+ * 6.

Copyright (C) 2011-2012 Nai Xia -+ * -+ * This is an improvement upon KSM. Some basic data structures and routines -+ * are borrowed from ksm.c . -+ * -+ * Its new features: -+ * 1. Full system scan: -+ * It automatically scans all user processes' anonymous VMAs. Kernel-user -+ * interaction to submit a memory area to KSM is no longer needed. -+ * -+ * 2. Rich area detection: -+ * It automatically detects rich areas containing abundant duplicated -+ * pages based. Rich areas are given a full scan speed. Poor areas are -+ * sampled at a reasonable speed with very low CPU consumption. -+ * -+ * 3. Ultra Per-page scan speed improvement: -+ * A new hash algorithm is proposed. As a result, on a machine with -+ * Core(TM)2 Quad Q9300 CPU in 32-bit mode and 800MHZ DDR2 main memory, it -+ * can scan memory areas that does not contain duplicated pages at speed of -+ * 627MB/sec ~ 2445MB/sec and can merge duplicated areas at speed of -+ * 477MB/sec ~ 923MB/sec. -+ * -+ * 4. Thrashing area avoidance: -+ * Thrashing area(an VMA that has frequent Ksm page break-out) can be -+ * filtered out. My benchmark shows it's more efficient than KSM's per-page -+ * hash value based volatile page detection. -+ * -+ * -+ * 5. Misc changes upon KSM: -+ * * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page -+ * comparison. It's much faster than default C version on x86. -+ * * rmap_item now has an struct *page member to loosely cache a -+ * address-->page mapping, which reduces too much time-costly -+ * follow_page(). -+ * * The VMA creation/exit procedures are hooked to let the Ultra KSM know. -+ * * try_to_merge_two_pages() now can revert a pte if it fails. No break_ -+ * ksm is needed for this case. -+ * -+ * 6. Full Zero Page consideration(contributed by Figo Zhang) -+ * Now uksmd consider full zero pages as special pages and merge them to an -+ * special unswappable uksm zero page. -+ */ -+ -+#include <linux/errno.h> -+#include <linux/mm.h> -+#include <linux/fs.h> -+#include <linux/mman.h> -+#include <linux/sched.h> -+#include <linux/sched/mm.h> -+#include <linux/sched/coredump.h> -+#include <linux/sched/cputime.h> -+#include <linux/rwsem.h> -+#include <linux/pagemap.h> -+#include <linux/rmap.h> -+#include <linux/spinlock.h> -+#include <linux/jhash.h> -+#include <linux/delay.h> -+#include <linux/kthread.h> -+#include <linux/wait.h> -+#include <linux/slab.h> -+#include <linux/rbtree.h> -+#include <linux/memory.h> -+#include <linux/mmu_notifier.h> -+#include <linux/swap.h> -+#include <linux/ksm.h> -+#include <linux/crypto.h> -+#include <linux/scatterlist.h> -+#include <crypto/hash.h> -+#include <linux/random.h> -+#include <linux/math64.h> -+#include <linux/gcd.h> -+#include <linux/freezer.h> -+#include <linux/oom.h> -+#include <linux/numa.h> -+#include <linux/sradix-tree.h> -+ -+#include <asm/tlbflush.h> -+#include "internal.h" -+ -+#ifdef CONFIG_X86 -+#undef memcmp -+ -+#ifdef CONFIG_X86_32 -+#define memcmp memcmpx86_32 -+/* -+ * Compare 4-byte-aligned address s1 and s2, with length n -+ */ -+int memcmpx86_32(void *s1, void *s2, size_t n) -+{ -+ size_t num = n / 4;
