This series provides an asynchronous means of reporting to a hypervisor
that a guest page is no longer in use and can have the data associated
with it dropped. To do this I have implemented functionality that allows
for what I am referring to as unused page reporting. The advantage of
unused page reporting is that we can support a significant amount of
memory over-commit with improved performance as we can avoid having to
write/read memory from swap as the VM will instead actively participate
in freeing unused memory so it doesn't have to be written.

The functionality for this is fairly simple. When enabled it will allocate
statistics to track the number of reported pages in a given free area.
When the number of free pages exceeds this value plus a high water value,
currently 32, it will begin performing page reporting which consists of
pulling non-reported pages off of the free lists of a given zone and
placing them into a scatterlist. The scatterlist is then given to the page
reporting device and it will perform the required action to make the pages
"reported", in the case of virtio-balloon this results in the pages being
madvised as MADV_DONTNEED. After this they are placed back on their
original free list. If they are not merged in freeing an additional bit is
set indicating that they are a "reported" buddy page instead of a standard
buddy page. The cycle then repeats with additional non-reported pages
being pulled until the free areas all consist of reported pages.

In order to try and keep the time needed to find a non-reported page to
a minimum we maintain a "reported_boundary" pointer. This pointer is used
by the get_unreported_pages iterator to determine at what point it should
resume searching for non-reported pages. In order to guarantee pages do
not get past the scan I have modified add_to_free_list_tail so that it
will not insert pages behind the reported_boundary.

If another process needs to perform a massive manipulation of the free
list, such as compaction, it can either reset a given individual boundary
which will push the boundary back to the list_head, or it can clear the
bit indicating the zone is actively processing which will result in the
reporting process resetting all of the boundaries for a given zone.

I am leaving a number of things hard-coded such as limiting the lowest
order processed to pageblock_order, and have left it up to the guest to
determine what the limit is on how many pages it wants to allocate to
process the hints. The upper limit for this is based on the size of the
queue used to store the scatterlist.

I wanted to avoid gaming the performance testing for this. As far as
possible gain a significant performance improvement should be visible in
cases where guests are forced to write/read from swap. As such, testing
it would be more of a benchmark of copying a page from swap versus just
allocating a zero page. I have been verifying that the memory is being
freed using memhog to allocate all the memory on the guest, and then
watching /proc/meminfo to verify the host sees the memory returned after
the test completes.

As far as possible regressions I have focused on cases where performing
the hinting would be non-optimal, such as cases where the code isn't
needed as memory is not over-committed, or the functionality is not in
use. I have been using the will-it-scale/page_fault1 test running with 16
vcpus and have modified it to use Transparent Huge Pages. With this I see
almost no difference with the patches applied and the feature disabled.
Likewise I see almost no difference with the feature enabled, but the
madvise disabled in the hypervisor due to a device being assigned. With
the feature fully enabled in both guest and hypervisor I see a regression
between -1.86% and -8.84% versus the baseline. I found that most of the
overhead was due to the page faulting/zeroing that comes as a result of
the pages having been evicted from the guest.

For info on earlier versions you will need to follow the links provided
with the respective versions.

Significant rewrite of page reporting functionality
  Updated logic to support interruptions from compaction
  get_unreported_page will now walk through reported sections
  Moved free_list manipulators out of mmzone.h and into page_alloc.c
  Removed page_reporting.h include from mmzone.h
  Split page_reporting.h between include/linux/ and mm/
  Added #include <asm/pgtable.h>" to mm/page_reporting.h

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

Move the head/tail adding logic out of the shuffle code and into the
__free_one_page function since ultimately that is where it is really
needed anyway. By doing this we should be able to reduce the overhead
and can consolidate all of the list addition bits in one spot.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

In order to enable the use of the zone from the list manipulator functions
I will need access to the zone pointer. As it turns out most of the
accessors were always just being directly passed &zone->free_area[order]
anyway so it would make sense to just fold that into the function itself
and pass the zone and order as arguments instead of the free area.

In order to be able to reference the zone we need to move the declaration
of the functions down so that we have the zone defined before we define the
list manipulation functions. Since the functions are only used in the file
mm/page_alloc.c we can just move them there to reduce noise in the header.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

In order to pave the way for free page reporting in virtualized
environments we will need a way to get pages out of the free lists and
identify those pages after they have been returned. To accomplish this,
this patch adds the concept of a Reported Buddy, which is essentially
meant to just be the Uptodate flag used in conjunction with the Buddy
page type.

It adds a set of pointers we shall call "reported_boundary" which
represent the upper boundary between the unreported and reported pages.
The general idea is that in order for a page to cross from one side of the
boundary to the other it will need to verify that it went through the
reporting process. Ultimately a free list has been fully processed when
the boundary has been moved from the tail all they way up to occupying the
first entry in the list.

One limitation to this approach is that it is essentially a linear search
and in the case of the free lists we can have pages added to either the
head or the tail of the list. In order to place limits on this we only
allow pages to be added before the reported_boundary instead of adding
to the tail itself. An added advantage to this approach is that we should
be reducing the overall memory footprint of the guest as it will be more
likely to recycle warm pages versus trying to allocate the reported pages
that were likely evicted from the guest memory.

Since we will only be reporting one zone at a time we keep the boundary
limited to being defined for just the zone we are currently reporting pages
from. Doing this we can keep the number of additional pointers needed quite
small. To flag that the boundaries are in place we use a single bit
in the zone to indicate that reporting and the boundaries are active.

We store the index of the boundary pointer used to track the reported page
in the page->index value. Doing this we can avoid unnecessary computation
to determine the index value again. There should be no issues with this as
the value is unused when the page is in the buddy allocator, and is reset
as soon as the page is removed from the free list.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

With this patch we are adding the pieces needed to enable the reporting of
pages to a specific device. That device needs to register a page reporting
device that can be used to handle notifications that that pages are unused.

Registering the device will in turn enable the notifications and allow page
reporting to be active. When the the device is unregistered it will disable
page reporting notifications. For now we only allow one page reporting
device to be registered at a time.

The determination of when to start reporting is based on the tracking of
the number of free pages in a given area versus the number of reported
pages in that area. We keep track of the number of reported pages per
free_area in a separate zone specific area. We do this to avoid modifying
the free_area structure as this can lead to false sharing for the highest
order with the zone lock which leads to a noticeable performance
degradation.

Once reporting has started get_unreported_pages will use the
reported_boundary pointers to track where it should resume processing the
free lists. It will go through and either set the index if it finds a
reported page, or it will attempt to isolate the page so that it can be
reported.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

Currently the page poisoning setting wasn't being enabled unless free page
hinting was enabled. However we will need the page poisoning tracking logic
as well for unused page reporting. As such pull it out and make it a
separate bit of config in the probe function.

In addition we can actually wrap the code in a check for NO_SANITY. If we
don't care what is actually in the page we can just default to 0 and leave
it there.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

Add support for the page reporting feature provided by virtio-balloon.
Reporting differs from the regular balloon functionality in that is is
much less durable than a standard memory balloon. Instead of creating a
list of pages that cannot be accessed the pages are only inaccessible
while they are being indicated to the virtio interface. Once the
interface has acknowledged them they are placed back into their respective
free lists and are once again accessible by the guest system.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

We need to make certain to advertise support for page poison tracking if
we want to actually get data on if the guest will be poisoning pages. So
if free page hinting is active we should add page poisoning support and
let the guest disable it if it isn't using it.

Page poisoning will result in a page being dirtied on free. As such we
cannot really avoid having to copy the page at least one more time since
we will need to write the poison value to the destination. As such we can
just ignore free page hinting if page poisoning is enabled as it will
actually reduce the work we have to do.

Add a bit for the page reporting feature provided by virtio-balloon.

This patch should be replaced once the feature is added to the Linux kernel
and the bit is backported into this exported kernel header.

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

Add support for what I am referring to as "unused page reporting".
Basically the idea is to function very similar to how the balloon works
in that we basically end up madvising the page as not being used. However
we don't really need to bother with any deflate type logic since the page
will be faulted back into the guest when it is read or written to.

This is meant to be a simplification of the existing balloon interface
to use for providing hints to what memory needs to be freed. I am assuming
this is safe to do as the deflate logic does not actually appear to do very
much other than tracking what subpages have been released and which ones
haven't.

I think this one can go in directly. Do you want me to merge it now?

That sounds good to me.

Do you know if you can also pull in QEMU 1/3 into QEMU as well since the
feature wasn't pulled into QEMU originally?

Thanks.

[-- Attachment #1: Type: text/plain, Size: 17391 bytes --]

Greeting,

FYI, we noticed a -1.2% regression of will-it-scale.per_process_ops due to commit:


commit: 0f5b256b2c35bf7d0faf874ed01227b4b7cb0118 ("[PATCH v10 3/6] mm: Introduce Reported pages")
url: https://github.com/0day-ci/linux/commits/Alexander-Duyck/mm-virtio-Provide-support-for-unused-page-reporting/20190919-015544


in testcase: will-it-scale
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:

	nr_task: 100%
	mode: process
	test: page_fault2
	cpufreq_governor: performance
	ucode: 0xb000036

test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale



If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen@intel.com>

So this seems to be costly.
I'm guessing it's the access to flags:


        /* zone flags, see below */
        unsigned long           flags;

        /* Primarily protects free_area */
        spinlock_t              lock;



which is in the same cache line as the lock.

I'm not sure what you mean by this being costly?

Also, at least on my system, pahole seems to indicate they are in
different cache lines.

/* --- cacheline 3 boundary (192 bytes) --- */
struct zone_padding        _pad1_;               /*   192     0 */
struct free_area           free_area[11];        /*   192  1144 */
/* --- cacheline 20 boundary (1280 bytes) was 56 bytes ago --- */
long unsigned int          flags;                /*  1336     8 */
/* --- cacheline 21 boundary (1344 bytes) --- */
spinlock_t                 lock;                 /*  1344     4 */

Basically these flags aren't supposed to be touched unless we are
holding the lock anyway so I am not sure it would be all that costly
for this setup. Basically we are holding the lock when the flag is set
or cleared, and we only set it if it is not already set. If needed
though I suppose I could look at moving the flags if you think that is
an issue. However I would probably need to add some additional padding
to prevent the lock from getting into the same cache line as the
free_area values.

I've just been wondering why does will it scale report a 1.5% regression
with this patch.

Are you talking about data you have collected from a test you have
run, or the data I have run?

In the case of the data I have run I notice almost no difference as
long as the pages are not actually being madvised. Once I turn on the
madvise then I start seeing the regression, but almost all of that is
due to page zeroing/faulting. There isn't expected to be a gain from
this patchset until you start having guests dealing with memory
overcommit on the host. Then at that point the patch set should start
showing gains when the madvise bits are enabled in QEMU.

Also the test I have been running is a modified version of the
page_fault1 test to specifically target transparent huge pages in
order to make this test that much more difficult, the standard
page_fault1 test wasn't showing much of anything since the overhead
for breaking a 2M page into 512 4K pages and zeroing those
individually in the guest  was essentially drowning out the effect of
the patches themselves.

About the kernel test robot auto report that was sent recently.

And if I'm correct, that regression is observable in case reporting is
not enabled. (so with this patch applied only, e.g., on a bare-metal system)

To be even more precise: # CONFIG_PAGE_REPORTING is not set

Even if it was, I'd hope for 0 overhead when not present runtime.

Right, because it will be included mostly in all kernels that support
virtio-balloon, so it applies to most distributions.

Thanks. For whatever reason it looks like my gmail decided to pop it
out of the thread so I hadn't seen it yet this morning.

I'll have to look into it. It doesn't make much sense to me why this
would have this much impact since especially in the disabled case the
changes should be quite small.

Is this any different from the previous version? The last review
feedback (both from me and Mel) was that we are not happy to have an
externally imposed constrains on how the page allocator is supposed to
maintain its free lists.

If this is really the only way to go forward then I would like to hear
very convincing arguments about other approaches not being feasible.
There are none in this cover letter unfortunately. This will be really a
hard sell without them.

The main change for v10 versus v9 is that I allow the page reporting
boundary to be overridden. Specifically there are two approaches that
can be taken.

The first is to simply reset the iterator for whatever list is
updated. What this will do is reset the iterator back to list_head and
then you can do whatever you want with that specific list.

The other option is to simply clear the ZONE_PAGE_REPORTING_ACTIVE
bit. That will essentially notify the page reporting code that any/all
hints that were recorded have been discarded and that it needs to
start over.

All I am trying to do with this approach is reduce the work. Without
doing this the code has to walk the entire free page list for the
higher orders every iteration and that will not be cheap. Admittedly
it is a bit more invasive than the cut/splice logic used in compaction
which is taking the pages it has already processed and moving them to
the other end of the list. However, I have reduced things so that we
only really are limiting where add_to_free_list_tail can place pages,
and we are having to check/push back the boundaries if a reported page
is removed from a free_list.

So I had considered several different approaches.

What I started out with was logic that was performing the hinting as a
part of the architecture specific arch_free_page call. It worked but
had performance issues as we were generating a hint per page freed
which has fairly high overhead.

The approach Nitesh has been using is to try and maintain a separate
bitmap of "dirty" pages that have recently been freed. There are a few
problems I saw with that approach. First is the fact that it becomes
lossy in that pages could be reallocated out while we are waiting for
the iterator to come through and process the page. This results in
there being a greater amount of work as we have to hunt and peck for
the pages, as such the zone lock has to be freed and reacquired often
which slows this approach down further. Secondly there is the
management of the bitmap itself and sparse memory which would likely
necessitate doing something similar to pageblock_flags on order to
support possible gaps in the zones.

I had considered trying to maintain a separate list entirely and have
the free pages placed there. However that was more invasive then this
solution. In addition modifying the free_list/free_area in any way is
problematic as it can result in the zone lock falling into the same
cacheline as the highest order free_area.

Ultimately what I settled on was the approach we have now where adding
a page to the head of the free_list is unchanged, adding a page to the
tail requires a check to see if the iterator is currently walking the
list, and removing the page requires pushing back the iterator if the
page is at the top of the reported list. I was trying to keep the
amount of code that would have to be touched in the non-reported case
to a minimum. With this we have to test for a bit in the zone flags if
adding to tail, and we have to test for a bit in the page on a
move/del from the freelist. So for the most common free/alloc cases we
would only have the impact of the one additional page flag check.

Adding to what Alexander said, I don't consider the other approaches
(especially the bitmap-based approach Nitesh is currently working on)
infeasible. There might be more rough edges (e.g., sparse zones) and
eventually sometimes a little more work to be done, but definitely
feasible. Incorporating stuff into the buddy might make some tasks
(e.g., identify free pages) more efficient.

I still somewhat like the idea of capturing hints of free pages (in
whatever data structure) and then going over the hints, seeing if the
pages are still free. Then only temporarily isolating the still-free
pages, reporting them, and un-isolating them after they were reported. I
like the idea that the pages are not fake-allocated but only temporarily
blocked. That works nicely e.g., with the movable zone (contain only
movable data).

But anyhow, after decades of people working on free page
hinting/reporting, I am happy with anything that gets accepted upstream :D

My plan was to get a framework ready which can perform decently and
is acceptable upstream (keeping core-mm changes to a minimum) and then keep
optimizing it for different use-cases.
Indeed, the bitmap-based approach may not be efficient for every available use
case. But then I am not sure if we want to target that, considering it may require
mm-changes.

One other change in this patch set is that I split the headers so that
there is an internal header that resides in the mm tree and an
external one that provides the page reporting device structure and the
register/unregister functions. All that virtio-balloon knows is that
it is registering a notifier and will be called with scatter gather
lists for memory that is not currently in use by the kernel. It has no
visibility into the internal free_areas or the current state of the
buddy allocator. Rather than having two blocks that are both trying to
maintain that state, I have consolidated it all into the buddy
allocator with page reporting.

Agreed. After working on this for 9 months I would be happy to get
something upstream that addresses this.

IBM upstreamed their proprietary solution - 45e576b1c3d0 ("S390] guest
page hinting light") - in 2008.

Rik has presented a generic approach in 2011 (!)
https://www.linux-kvm.org/images/f/ff/2011-forum-memory-overcommit.pdf

I think Nitesh has been working on this (initially as an Intern) since
Mid 2017.

So yeah, this stuff has quite some history :)

OK, this is slightly better than pushing the allocator to the corner.
The allocator really has to be under control of its data structures.
I would still be happier if the allocator wouldn't really have to bother
about somebody snooping its internal state to do its own thing. So
please make sure to describe why and how much this really matters.

Thanks this is certainly useful and it would have been even more so if
you gave some rough numbers to quantify how much overhead for different
solutions we are talking about here.

Okay I can try to do that. I suppose if nothing else I can put
together a test patch that reverts these bits and can add
documentation on the amount of regression seen without those bits. I
should be able to get that taken care of and a v11 out in the next few
days.

Well without this I believe the work goes from being O(n) to O(n^2) as
we would have to walk the list every time we pull the batch of pages,
so without the iterator we end up having walk the page list
repeatedly. I suspect it becomes more expensive the more memory we
have. I'll be able to verify it later today once I can generate some
numbers.

I'll see what I can do. As far as the bitmap solution I think Nitesh
has numbers for what he has been able to get out of it. At this point
I would assume his solution for the virtio/QEMU bits is probably
identical to mine so it should be easier to get an apples to apples
comparison.

Thanks.
