Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch-set follows the main idea discussed at 2012 LSFMMS session:
"Ballooning for transparent huge pages" -- http://lwn.net/Articles/490114/
to introduce the required changes to the virtio_balloon driver, as well as
the changes to the core compaction & migration bits, in order to make those
subsystems aware of ballooned pages and allow memory balloon pages become
movable within a guest, thus avoiding the aforementioned fragmentation issue

Following are numbers that prove this patch benefits on allowing compaction
to be more effective at memory ballooned guests.

Results for STRESS-HIGHALLOC benchmark, from Mel Gorman's mmtests suite,
running on a 4gB RAM KVM guest which was ballooning 512mB RAM in 64mB chunks,
at every minute (inflating/deflating), while test was running:

This patch introduces MIGRATEPAGE_SUCCESS as the default return code
for address_space_operations.migratepage() method and documents the
expected return code for the same method in failure cases.

  To: linux-mm
  Cc: linux-kernel, virtualization, Andrew Morton, Mel Gorman,
	Michael S. Tsirkin, Minchan Kim, Rik van Riel, Rusty Russell,
	aquini

This patch introduces MIGRATEPAGE_SUCCESS as the default return code
for address_space_operations.migratepage() method and documents the
expected return code for the same method in failure cases.

This patch overhauls struct address_space.assoc_mapping renaming it to
address_space.private_data and its type is redefined to void*.
By this approach we consistently name the .private_* elements from
struct address_space as well as allow extended usage for address_space
association with other data structures through ->private_data.

Also, all users of old ->assoc_mapping element are converted to reflect
its new name and type change (->private_data).

This patch overhauls struct address_space.assoc_mapping renaming it to
address_space.private_data and its type is redefined to void*.
By this approach we consistently name the .private_* elements from
struct address_space as well as allow extended usage for address_space
association with other data structures through ->private_data.

Also, all users of old ->assoc_mapping element are converted to reflect
its new name and type change (->private_data).

* [PATCH v12 3/7] mm: introduce a common interface for balloon pages mobility

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch introduces a common interface to help a balloon driver on
making its page set movable to compaction, and thus allowing the system
to better leverage the compation efforts on memory defragmentation.

+ * Common interface definitions for making balloon pages movable by compaction.
+ *
+ * Despite being perfectly possible to perform ballooned pages migration, they
+ * make a special corner case to compaction scans because balloon pages are not
+ * enlisted at any LRU list like the other pages we do compact / migrate.
+ *
+ * As the page isolation scanning step a compaction thread does is a lockless
+ * procedure (from a page standpoint), it might bring some racy situations while
+ * performing balloon page compaction. In order to sort out these racy scenarios
+ * and safely perform balloon's page compaction and migration we must, always,
+ * ensure following these three simple rules:
+ *
+ *   i. when updating a balloon's page ->mapping element, strictly do it under
+ *      the following lock order, independently of the far superior
+ *      locking scheme (lru_lock, balloon_lock):
+ *	    +-page_lock(page);
+ *	      +--spin_lock_irq(&b_dev_info->pages_lock);
+ *	            ... page->mapping updates here ...
+ *
+ *  ii. before isolating or dequeueing a balloon page from the balloon device
+ *      pages list, the page reference counter must be raised by one and the
+ *      extra refcount must be dropped when the page is enqueued back into
+ *      the balloon device page list, thus a balloon page keeps its reference
+ *      counter raised only while it is under our special handling;
+ *
+ * iii. after the lockless scan step have selected a potential balloon page for
+ *      isolation, re-test the page->mapping flags and the page ref counter
+ *      under the proper page lock, to ensure isolating a valid balloon page
+ *      (not yet isolated, nor under release procedure)
+ *
+ * The functions provided by this interface are placed to help on coping with
+ * the aforementioned balloon page corner case, as well as to ensure the simple
+ * set of exposed rules are satisfied while we are dealing with balloon pages
+ * compaction / migration.

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch introduces a common interface to help a balloon driver on
making its page set movable to compaction, and thus allowing the system
to better leverage the compation efforts on memory defragmentation.

+ *
+ * Common interface definitions for making balloon pages movable by compaction.
+ *
+ * Despite being perfectly possible to perform ballooned pages migration, they
+ * make a special corner case to compaction scans because balloon pages are not
+ * enlisted at any LRU list like the other pages we do compact / migrate.
+ *
+ * As the page isolation scanning step a compaction thread does is a lockless
+ * procedure (from a page standpoint), it might bring some racy situations while
+ * performing balloon page compaction. In order to sort out these racy scenarios
+ * and safely perform balloon's page compaction and migration we must, always,
+ * ensure following these three simple rules:
+ *
+ *   i. when updating a balloon's page ->mapping element, strictly do it under
+ *      the following lock order, independently of the far superior
+ *      locking scheme (lru_lock, balloon_lock):
+ *	    +-page_lock(page);
+ *	      +--spin_lock_irq(&b_dev_info->pages_lock);
+ *	            ... page->mapping updates here ...
+ *
+ *  ii. before isolating or dequeueing a balloon page from the balloon device
+ *      pages list, the page reference counter must be raised by one and the
+ *      extra refcount must be dropped when the page is enqueued back into
+ *      the balloon device page list, thus a balloon page keeps its reference
+ *      counter raised only while it is under our special handling;
+ *
+ * iii. after the lockless scan step have selected a potential balloon page for
+ *      isolation, re-test the page->mapping flags and the page ref counter
+ *      under the proper page lock, to ensure isolating a valid balloon page
+ *      (not yet isolated, nor under release procedure)
+ *
+ * The functions provided by this interface are placed to help on coping with
+ * the aforementioned balloon page corner case, as well as to ensure the simple
+ * set of exposed rules are satisfied while we are dealing with balloon pages
+ * compaction / migration.

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch introduces a common interface to help a balloon driver on
making its page set movable to compaction, and thus allowing the system
to better leverage the compation efforts on memory defragmentation.

+ * include/linux/balloon_compaction.h
+ *
+ * Common interface definitions for making balloon pages movable by compaction.
+ *
+ * Despite being perfectly possible to perform ballooned pages migration, they
+ * make a special corner case to compaction scans because balloon pages are not
+ * enlisted at any LRU list like the other pages we do compact / migrate.
+ *
+ * As the page isolation scanning step a compaction thread does is a lockless
+ * procedure (from a page standpoint), it might bring some racy situations while
+ * performing balloon page compaction. In order to sort out these racy scenarios
+ * and safely perform balloon's page compaction and migration we must, always,
+ * ensure following these three simple rules:
+ *
+ *   i. when updating a balloon's page ->mapping element, strictly do it under
+ *      the following lock order, independently of the far superior
+ *      locking scheme (lru_lock, balloon_lock):
+ *	    +-page_lock(page);
+ *	      +--spin_lock_irq(&b_dev_info->pages_lock);
+ *	            ... page->mapping updates here ...
+ *
+ *  ii. before isolating or dequeueing a balloon page from the balloon device
+ *      pages list, the page reference counter must be raised by one and the
+ *      extra refcount must be dropped when the page is enqueued back into
+ *      the balloon device page list, thus a balloon page keeps its reference
+ *      counter raised only while it is under our special handling;
+ *
+ * iii. after the lockless scan step have selected a potential balloon page for
+ *      isolation, re-test the page->mapping flags and the page ref counter
+ *      under the proper page lock, to ensure isolating a valid balloon page
+ *      (not yet isolated, nor under release procedure)
+ *
+ * The functions provided by this interface are placed to help on coping with
+ * the aforementioned balloon page corner case, as well as to ensure the simple
+ * set of exposed rules are satisfied while we are dealing with balloon pages
+ * compaction / migration.

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch introduces the helper functions as well as the necessary changes
to teach compaction and migration bits how to cope with pages which are
part of a guest memory balloon, in order to make them movable by memory
compaction procedures.

* [PATCH v12 4/7] mm: introduce compaction and migration for ballooned pages

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch introduces the helper functions as well as the necessary changes
to teach compaction and migration bits how to cope with pages which are
part of a guest memory balloon, in order to make them movable by memory
compaction procedures.

Memory fragmentation introduced by ballooning might reduce significantly

thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

Besides making balloon pages movable at allocation time and introducing
the necessary primitives to perform balloon page migration/compaction,
this patch also introduces the following locking scheme, in order to
enhance the syncronization methods for accessing elements of struct
virtio_balloon, thus providing protection against concurrent access
introduced by parallel memory migration threads.

 - balloon_lock (mutex) : synchronizes the access demand to elements of
                          struct virtio_balloon and its queue operations;

* [PATCH v12 5/7] virtio_balloon: introduce migration primitives to balloon pages

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

Besides making balloon pages movable at allocation time and introducing
the necessary primitives to perform balloon page migration/compaction,
this patch also introduces the following locking scheme, in order to
enhance the syncronization methods for accessing elements of struct
virtio_balloon, thus providing protection against concurrent access
introduced by parallel memory migration threads.

 - balloon_lock (mutex) : synchronizes the access demand to elements of
                          struct virtio_balloon and its queue operations;

* [PATCH v12 6/7] mm: introduce putback_movable_pages()

The PATCH "mm: introduce compaction and migration for virtio ballooned pages"
hacks around putback_lru_pages() in order to allow ballooned pages to be
re-inserted on balloon page list as if a ballooned page was like a LRU page.

As ballooned pages are not legitimate LRU pages, this patch introduces
putback_movable_pages() to properly cope with cases where the isolated
pageset contains ballooned pages and LRU pages, thus fixing the mentioned
inelegant hack around putback_lru_pages().

* [PATCH v12 6/7] mm: introduce putback_movable_pages()

The PATCH "mm: introduce compaction and migration for virtio ballooned pages"
hacks around putback_lru_pages() in order to allow ballooned pages to be
re-inserted on balloon page list as if a ballooned page was like a LRU page.

As ballooned pages are not legitimate LRU pages, this patch introduces
putback_movable_pages() to properly cope with cases where the isolated
pageset contains ballooned pages and LRU pages, thus fixing the mentioned
inelegant hack around putback_lru_pages().

Andrew, 

could you drop the earlier review (v11) and pick this submission (v12) instead,
please?


Aside: before submitting I rebased the series on -next-20121109, after reverting
the v11 commits, to make those clean-up hunks from PATCH 01 apply smoothly.

My guess is that we see those because of a race during the check in

Sasha, could you share your .config and steps you did used with trinity? So I
can attempt to reproduce this issue you reported.

Howdy Sasha,

After several hours since last Sunday running trinity tests on a traditional
KVM-QEMU guest as well as running it on a lkvm guest (both running
next-20121115) I couldn't hit a single time the crash you've reported,
(un)fortunately.

Also, the .config you gave me, applied on top of next-20121115, haven't produced
the same bin you've running and hitting the mentioned bug, apparently.

Here's the RIP for your crash:
[ 1642.783728] BUG: unable to handle kernel NULL pointer dereference at
0000000000000194
[ 1642.785083] IP: [<ffffffff8122b354>] isolate_migratepages_range+0x344/0x7b0


And here's the symbol address for the next-20121115 with your .config I've been
running tests on:
[raquini@x61 linux]$ nm -n vmlinux | grep isolate_migratepages_range 
ffffffff8122d890 T isolate_migratepages_range

Also, it seems quite clear I'm missing something from your tree, as applying the
RIP displacement (0x344) to my local isolate_migratepages_range sym addr leads
me to the _middle_ of a instruction opcode that does not dereference any
pointers at all.

So, if you're consistently reproducing the same crash, consider to share with us
a disassembled dump from the isolate_migratepages_range() you're running along
with the crash stack-dump, please.

Cheers!

Odd... I can see it happening here every couple of hours.

Yup, I carry another small fix to mpol (which is unrelated to this one).

Sure!

The call chain is:

	isolate_migratepages_range
		balloon_page_movable
			__is_movable_balloon_page
				mapping_balloon

mapping_balloon() fails because it checks for mapping to be non-null (and it is -
it's usually a small value like 0x50), and then it dereferences that.

The relevant assembly is:

static inline int mapping_balloon(struct address_space *mapping)
{
        return mapping && test_bit(AS_BALLOON_MAP, &mapping->flags);
    17ab:       48 85 c0                test   %rax,%rax
    17ae:       0f 84 4c 02 00 00       je     1a00 <isolate_migratepages_range+0x590>
    17b4:       48 8b 80 40 01 00 00    mov    0x140(%rax),%rax
    17bb:       a9 00 00 00 20          test   $0x20000000,%eax
    17c0:       0f 84 3a 02 00 00       je     1a00 <isolate_migratepages_range+0x590>

It dies on 17b4.

Let me know if you need anything else from me, I can also add debug code into the
kernel if it would help you...


Thanks,
Sasha

I've modified it a bit to decrease the noise:

And managed to reproduce it only once through last night, here is the dump I got
before the oops:

Thanks alot for following up this one Sasha.


We're stumbling across a private page -- seems something in your setup is doing
this particular usage, and that's probably why I'm not seeing the same here.

Regardless being a particular case or not, we shouldn't be poking at that
private page, so I figured the tests I'm doing at balloon_page_movable() are
incomplete and dumb.

Perhaps, a better way to proceed here would be assuring the NR_PAGEFLAGS
rightmost bits from page->flags are all cleared, as this is the state a page
coming from buddy to the balloon list will be, and this is the state the balloon
page flags will be kept as long as it lives as such (we don't play with any flag
at balloon level).


Here goes what I'll propose after you confirm it doesn't trigger your crash
anymore, as it simplifies the code and reduces the testing battery @
balloon_page_movable() -- ballooned pages have no flags set, 1 refcount and 0
mapcount, always.


Could you give this a try?

Thank you!

Thanks alot for following up this one Sasha.


We're stumbling across a private page -- seems something in your setup is doing
this particular usage, and that's probably why I'm not seeing the same here.

Regardless being a particular case or not, we shouldn't be poking at that
private page, so I figured the tests I'm doing at balloon_page_movable() are
incomplete and dumb.

Perhaps, a better way to proceed here would be assuring the NR_PAGEFLAGS
rightmost bits from page->flags are all cleared, as this is the state a page
coming from buddy to the balloon list will be, and this is the state the balloon
page flags will be kept as long as it lives as such (we don't play with any flag
at balloon level).


Here goes what I'll propose after you confirm it doesn't trigger your crash
anymore, as it simplifies the code and reduces the testing battery @
balloon_page_movable() -- ballooned pages have no flags set, 1 refcount and 0
mapcount, always.


Could you give this a try?

Thank you!

* [PATCH v12 0/7] make balloon pages movable by compaction
@ 2012-11-11 19:01 Rafael Aquini

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch-set follows the main idea discussed at 2012 LSFMMS session:
"Ballooning for transparent huge pages" -- http://lwn.net/Articles/490114/
to introduce the required changes to the virtio_balloon driver, as well as
the changes to the core compaction & migration bits, in order to make those
subsystems aware of ballooned pages and allow memory balloon pages become
movable within a guest, thus avoiding the aforementioned fragmentation issue

Following are numbers that prove this patch benefits on allowing compaction
to be more effective at memory ballooned guests.

Results for STRESS-HIGHALLOC benchmark, from Mel Gorman's mmtests suite,
running on a 4gB RAM KVM guest which was ballooning 512mB RAM in 64mB chunks,
at every minute (inflating/deflating), while test was running:
