Introduction
============
DAMON is a data access monitoring framework subsystem for the Linux kernel.
The core mechanisms of DAMON called 'region based sampling' and 'adaptive
regions adjustment' (refer to 'mechanisms.rst' in the 11th patch of this
patchset for the detail) make it
- accurate (The monitored information is useful for DRAM level memory
management. It might not appropriate for Cache-level accuracy, though.),
- light-weight (The monitoring overhead is low enough to be applied online
while making no impact on the performance of the target workloads.), and
- scalable (the upper-bound of the instrumentation overhead is controllable
regardless of the size of target workloads.).
Using this framework, therefore, the kernel's core memory management mechanisms
such as reclamation and THP can be optimized for better memory management. The
experimental memory management optimization works that incurring high
instrumentation overhead will be able to have another try. In user space,
meanwhile, users who have some special workloads will be able to write
personalized tools or applications for deeper understanding and specialized
optimizations of their systems.
Evaluations
===========
We evaluated DAMON's overhead, monitoring quality and usefulness using 25
realistic workloads on my QEMU/KVM based virtual machine running a kernel that
v16 DAMON patchset is applied.
DAMON is lightweight. It increases system memory usage by only -0.25% and
consumes less than 1% CPU time in most case. It slows target workloads down by
only 0.94%.
DAMON is accurate and useful for memory management optimizations. An
experimental DAMON-based operation scheme for THP, ‘ethp’, removes 31.29% of
THP memory overheads while preserving 60.64% of THP speedup. Another
experimental DAMON-based ‘proactive reclamation’ implementation, ‘prcl’,
reduces 87.95% of residential sets and 29.52% of system memory footprint while
incurring only 2.15% runtime overhead in the best case (parsec3/freqmine).
NOTE that the experimentail THP optimization and proactive reclamation are not
for production, just only for proof of concepts.
Please refer to the official document[1] or "Documentation/admin-guide/mm: Add
a document for DAMON" patch in this patchset for detailed evaluation setup and
results.

Baseline and Complete Git Trees
===============================
The patches are based on the v5.7. You can also clone the complete git
tree:
$ git clone git://github.com/sjp38/linux -b damon/patches/v16
The web is also available:
https://github.com/sjp38/linux/releases/tag/damon/patches/v16
There are a couple of trees for entire DAMON patchset series. It includes
future features. The first one[1] contains the changes for latest release,
while the other one[2] contains the changes for next release.

Sequence Of Patches
===================
The 1st patch exports 'lookup_page_ext()' to GPL modules so that it can be used
by DAMON even though it is built as a loadable module.
Next four patches implement the target address space independent core logics of
DAMON and it's programming interface. The 2nd patch introduces DAMON module,
it's data structures, and data structure related common functions. Following
three patches (3rd to 5th) implements the core mechanisms of DAMON, namely
regions based sampling (patch 3), adaptive regions adjustment (patch 4), and
dynamic memory mapping chage adoption (patch 5).
The following one (patch 6) implements the virtual memory address space
specific functions.
Following four patches are for more user friendly interfaces. The 7th patch
implements recording of access patterns in DAMON. Each of next two patches
(8th and 9th) respectively adds a tracepoint for other tracepoints supporting
tracers such as perf, and a debugfs interface for privileged people and/or
programs in user space.
Two patches for high level users of DAMON follows. To provide a minimal
reference to the debugfs interface and for high level use/tests of the DAMON,
the next patch (10th) implements an user space tool. The 11th patch adds a
document for administrators of DAMON.
Next two patches are for tests. The 12th patch provides unit tests (based on
the kunit) while the 13th patch adds user space tests (based on the kselftest).
Finally, the last patch (14th) updates the MAINTAINERS file.
Patch History
=============
This version of patchset merges first, second, and sixth patches in the CDAMON
patchset[1] for better readability. As the changes are not subtle,
'Reviewed-by's I previously received on the changes affected patches are also
dropped.

2.17.1
From: SeongJae Park <[email protected]>
This commit adds a debugfs interface for DAMON. It works for the
virtual address spaces monitoring.
DAMON exports four files, ``attrs``, ``pids``, ``record``, and
``monitor_on`` under its debugfs directory, ``<debugfs>/damon/``.
Attributes
----------
Users can read and write the ``sampling interval``, ``aggregation
interval``, ``regions update interval``, and min/max number of
monitoring target regions by reading from and writing to the ``attrs``
file. For example, below commands set those values to 5 ms, 100 ms,
1,000 ms, 10, 1000 and check it again::
# cd <debugfs>/damon
# echo 5000 100000 1000000 10 1000 > attrs
# cat attrs
5000 100000 1000000 10 1000
Target PIDs
-----------
Users can read and write the pids of current monitoring target processes
by reading from and writing to the ``pids`` file. For example, below
commands set processes having pids 42 and 4242 as the processes to be
monitored and check it again::
# cd <debugfs>/damon
# echo 42 4242 > pids
# cat pids
42 4242
Note that setting the pids doesn't start the monitoring.
Record
------
DAMON supports direct monitoring result record feature. The recorded
results are first written to a buffer and flushed to a file in batch.
Users can set the size of the buffer and the path to the result file by
reading from and writing to the ``record`` file. For example, below
commands set the buffer to be 4 KiB and the result to be saved in
'/damon.data'.
# cd <debugfs>/damon
# echo 4096 /damon.data > pids
# cat record
4096 /damon.data
Turning On/Off
--------------
You can check current status, start and stop the monitoring by reading
from and writing to the ``monitor_on`` file. Writing ``on`` to the file
starts DAMON to monitor the target processes with the attributes.
Writing ``off`` to the file stops DAMON. DAMON also stops if every
target processes is terminated. Below example commands turn on, off,
and check status of DAMON::
# cd <debugfs>/damon
# echo on > monitor_on
# echo off > monitor_on
# cat monitor_on
off
Please note that you cannot write to the ``attrs`` and ``pids`` files
while the monitoring is turned on. If you write to the files while
DAMON is running, ``-EINVAL`` will be returned.

2.17.1
From: SeongJae Park <[email protected]>
This commit implements the recording feature of DAMON. If this feature
is enabled, DAMON writes the monitored access patterns in its binary
format into a file which specified by the user. This is already able to
be implemented by each user using the callbacks. However, as the
recording is expected to be used widely, this commit implements the
feature in the DAMON, for more convenience and efficiency.

+ * Test damon_three_regions_in_vmas() function

+ * DAMON converts the complex and dynamic memory mappings of each target task
+ * to three discontiguous regions which cover every mapped areas. However, the
+ * three regions should not include the two biggest unmapped areas in the
+ * original mapping, because the two biggest areas are normally the areas
+ * between 1) heap and the mmap()-ed regions, and 2) the mmap()-ed regions and
+ * stack. Because these two unmapped areas are very huge but obviously never
+ * accessed, covering the region is just a waste.
+ *
+ * 'damon_three_regions_in_vmas() receives an address space of a process. It
+ * first identifies the start of mappings, end of mappings, and the two biggest
+ * unmapped areas. After that, based on the information, it constructs the
+ * three regions and returns. For more detail, refer to the comment of
+ * 'damon_init_regions_of()' function definition in 'mm/damon.c' file.
+ *
+ * For example, suppose virtual address ranges of 10-20, 20-25, 200-210,
+ * 210-220, 300-305, and 307-330 (Other comments represent this mappings in
+ * more short form: 10-20-25, 200-210-220, 300-305, 307-330) of a process are
+ * mapped. To cover every mappings, the three regions should start with 10,
+ * and end with 305. The process also has three unmapped areas, 25-200,
+ * 220-300, and 305-307. Among those, 25-200 and 220-300 are the biggest two
+ * unmapped areas, and thus it should be converted to three regions of 10-25,

2.17.1
From: SeongJae Park <[email protected]>
This commit adds a tracepoint for DAMON. It traces the monitoring
results of each region for each aggregation interval. Using this, DAMON
will be easily integrated with any tracepoints supporting tools such as
perf.

+Evaluation
+==========
+
+DAMON is lightweight. It increases system memory usage by only -0.25% and
+consumes less than 1% CPU time in most case. It slows target workloads down by
+only 0.94%.
+
+DAMON is accurate and useful for memory management optimizations. An
+experimental DAMON-based operation scheme for THP, 'ethp', removes 31.29% of
+THP memory overheads while preserving 60.64% of THP speedup. Another
+experimental DAMON-based 'proactive reclamation' implementation, 'prcl',
+reduces 87.95% of residential sets and 29.52% of system memory footprint while
+incurring only 2.15% runtime overhead in the best case (parsec3/freqmine).
+
+Setup
+=====
+
+On a QEMU/KVM based virtual machine utilizing 20GB of RAM and hosted by an
+Intel i7 machine running Ubuntu 18.04, I measure runtime and consumed system
+memory while running various realistic workloads with several configurations.
+I use 13 and 12 workloads in PARSEC3 [3]_ and SPLASH-2X [4]_ benchmark suites,
+respectively. I use another wrapper scripts [5]_ for convenient setup and run
+of the workloads.
+
+Measurement
+-----------
+
+For the measurement of the amount of consumed memory in system global scope, I
+drop caches before starting each of the workloads and monitor 'MemFree' in the
+'/proc/meminfo' file. To make results more stable, I repeat the runs 5 times
+and average results.
+
+Configurations
+--------------
+
+The configurations I use are as below.
+
+- orig: Linux v5.7 with 'madvise' THP policy
+- rec: 'orig' plus DAMON running with virtual memory access recording
+- prec: 'orig' plus DAMON running with physical memory access recording
+- thp: same with 'orig', but use 'always' THP policy
+- ethp: 'orig' plus a DAMON operation scheme, 'efficient THP'
+- prcl: 'orig' plus a DAMON operation scheme, 'proactive reclaim [6]_'
+
+I use 'rec' for measurement of DAMON overheads to target workloads and system
+memory. 'prec' is for physical memory monitroing and recording. It monitors
+17GB sized 'System RAM' region. The remaining configs including 'thp', 'ethp',
+and 'prcl' are for measurement of DAMON monitoring accuracy.
+
+'ethp' and 'prcl' are simple DAMON-based operation schemes developed for
+proof of concepts of DAMON. 'ethp' reduces memory space waste of THP by using
+DAMON for the decision of promotions and demotion for huge pages, while 'prcl'
+is as similar as the original work. Those are implemented as below::
+
+ # format: <min/max size> <min/max frequency (0-100)> <min/max age> <action>
+ # ethp: Use huge pages if a region shows >=5% access rate, use regular
+ # pages if a region >=2MB shows <5% access rate for >=13 seconds
+ null null 5 null null null hugepage
+ 2M null null null 13s null nohugepage
+
+ # prcl: If a region >=4KB shows <=5% access rate for >=7 seconds, page out.
+ 4K null null 5 7s null pageout
+
+Note that both 'ethp' and 'prcl' are designed with my only straightforward
+intuition because those are for only proof of concepts and monitoring accuracy
+of DAMON. In other words, those are not for production. For production use,
+those should be more tuned.

+
+DAMON Overheads
+---------------
+
+In total, DAMON virtual memory access recording feature ('rec') incurs 0.94%
+runtime overhead and -0.25% memory space overhead. Even though the size of the
+monitoring target region becomes much larger with the physical memory access
+recording ('prec'), it still shows only modest amount of overhead (1.10% for
+runtime and -3.09% for memory footprint).
+
+For a convenience test run of 'rec' and 'prec', I use a Python wrapper. The
+wrapper constantly consumes about 10-15MB of memory. This becomes a high
+memory overhead if the target workload has a small memory footprint.
+Nonetheless, the overheads are not from DAMON, but from the wrapper, and thus
+should be ignored. This fake memory overhead continues in 'ethp' and 'prcl',
+as those configurations are also using the Python wrapper.
+
+
+Efficient THP
+-------------
+
+THP 'always' enabled policy achieves 6.20% speedup but incurs 6.04% memory
+overhead. It achieves 44.76% speedup in the best case, but 81.15% memory
+overhead in the worst case. Interestingly, both the best and worst-case are
+with 'splash2x/ocean_ncp').
+
+The 2-lines implementation of data access monitoring based THP version ('ethp')
+shows 3.76% speedup and 4.15% memory overhead. In other words, 'ethp' removes
+31.29% of THP memory waste while preserving 60.64% of THP speedup in total. In
+the case of the 'splash2x/ocean_ncp', 'ethp' removes 82.66% of THP memory waste
+while preserving 52.85% of THP speedup.
+
+
+Proactive Reclamation
+---------------------
+
+As similar to the original work, I use 4G 'zram' swap device for this
+configuration.
+
+In total, our 1 line implementation of Proactive Reclamation, 'prcl', incurred
+6.48% runtime overhead in total while achieving 5.12% system memory usage
+reduction.
+
+Nonetheless, as the memory usage is calculated with 'MemFree' in
+'/proc/meminfo', it contains the SwapCached pages. As the swapcached pages can
+be easily evicted, I also measured the residential set size of the workloads::

+==========================
+Frequently Asked Questions
+==========================
+
+Why a new module, instead of extending perf or other user space tools?
+======================================================================
+
+First, because it needs to be lightweight as much as possible so that it can be
+used online, any unnecessary overhead such as kernel - user space context
+switching cost should be avoided. Second, DAMON aims to be used by other
+programs including the kernel. Therefore, having a dependency on specific
+tools like perf is not desirable. These are the two biggest reasons why DAMON
+is implemented in the kernel space.
+
+
+Can 'idle pages tracking' or 'perf mem' substitute DAMON?
+=========================================================
+
+Idle page tracking is a low level primitive for access check of each physical
+page frame. 'perf mem' is similar, though it can use sampling to minimize the
+overhead. DAMON is a higher-level framework for access patterns of data objects
+that focused on memory management optimization and providing sophisticated
+features for that including the overhead handling. Therefore, 'idle pages
+tracking' and 'perf mem' could provide a subset of DAMON's output, but cannot
+substitute DAMON. Rather than that, DAMON could use those as it's low-level
+primitives.
+
+
+How can I optimize my system's memory management using DAMON?
+=============================================================
+
+Because there are several ways for the DAMON-based optimizations, we wrote a
+separate document, :doc:`guide`. Please refer to that.
+
+
+Does DAMON support virtual memory only?
+========================================
+
+For now, yes. But, DAMON will be able to support various address spaces
+including physical memory in near future. An RFC patchset [1]_ for this
+extension is already available. Please refer :doc:`plans` for detailed plan
+for this.

+====================
+The Beginner's Guide
+====================
+
+This document is to help you estimating the amount of benefit that you could
+get from DAMON, and to let you know how you could maximize the improvement.
+You are assumed to already read :doc:`start`.
+
+
+Check The Signs
+===============
+
+DAMON cannot provide the same amount of benefit to every workload. Therefore
+you should first guess how much improvements you could get using DAMON. If
+some of the below conditions match your situation, you could consider the use
+of DAMON.
+
+
+- *Low IPC and High Cache Miss Ratios.* Low IPC means most of the CPU time is
+ spent waiting for the completion of time-consuming operations such as memory
+ access, while high cache miss ratios mean the caches don't help it well.
+ DAMON is not for cache level optimization, but DRAM level. However,
+ improving DRAM management will also help this case by reducing the memory
+ operation latency.
+- *Memory Over-commitment and Unknown Users.* If you are doing memory
+ overcommitment and you cannot control every user of your system, a memory
+ bank run could happen at any time. You can estimate when it will happen
+ based on DAMON's monitoring results and act earlier to avoid or deal better
+ with the crisis.
+- *Frequent Memory Pressure.* Frequent memory pressure means the wrong
+ configuration or existence of memory hogs. DAMON will help you find the
+ right configuration and/or the criminals.
+- *Heterogeneous Memory System.* If your system is utilizing memory devices
+ that placed between DRAM and traditional hard disks, such as non-volatile
+ memory or fast SSDs, DAMON could help you utilizing the devices more
+ efficiently.
+
+
+Profile
+=======
+
+If you found some positive signals, you could start by profiling your workloads
+using DAMON. Find major workloads on your systems and analyze their data
+access pattern to find something wrong or can be improved. The DAMON user
+space tool (``damo``) will be enough for this.
+
+We recommend you to start from working set size distribution check using ``damo
+report wss``. If the distribution is ununiform or quite different from what
+you estimated, you could consider `Memory Configuration`_ optimization.
+
+Then, review the overall access pattern in heatmap form using ``damo report
+heats``. If it shows a simple pattern consists of a small number of memory
+regions having high contrast of access temperature, you could consider `Manual
+Program Optimization`_.
+
+You don't need to take only one approach among the above plans, but you could
+use multiple of the above approaches to maximize the benefit. If you still
+want to absorb more benefits, you should develop `Personalized DAMON
+Application`_ for your special case.
+
+
+Optimize
+========
+
+If the profiling result also says it's worth trying some optimization, you
+could consider the below approaches. Note that some of the below approaches
+assume that your systems are configured with swap devices or other types of
+auxiliary memory so that you don't need to accommodate the whole working set in
+the main memory. Most of the detailed optimization should be made on your
+concrete understanding of your swap and/or your auxiliary memory performance.
+
+
+Memory Configuration
+--------------------
+
+DRAM is highly performance critical but expensive and heavily consumes the
+power. However, knowing the real important working set size is hard and thus
+people usually equips unnecessarily large or too small DRAM. So many problems
+come from such wrong configurations.
+
+Using the working set size distribution report provided by ``damo report wss``,
+you can know the real needs and make reasonable tradeoffs. For example,
+roughly speaking, if you worry about only 95 percentile latency, you don't need
+to equip DRAM of a size larger than 95 percentile working set size. If you
+were suffered from frequent memory pressure, you will also easily know how much
+DRAM you should buy.
+
+Let's see a real example. Below are the heatmap and the working set size
+distributions/changes of ``freqmine`` workload in PARSEC3 benchmark suite. The
+working set size spikes up to 700 MiB, but keeps smaller than 100 MiB for more
+than 95% of the time. Even though you give only 100 MiB of memory space to the
+workload, it will work well for 95% of the time. Meanwhile, you can save the
+600 MiB of memory space.

+
+
+Program Modification
+--------------------
+
+If the data access pattern heatmap plotted using ``damo report heats`` is quite
+simple and clear, you could be able to know how the thing is going in the
+workload, and how you could make optimize memory management.
+
+For example, suppose that the workload has two big memory object but only one
+object is frequently accessed while the other is only occasionally scanned.
+Then, you could modify the program source code to invoke ``mlock()`` or
+``madvise()`` with ``WILLNEED`` system call for the hot object. Or, you could
+use ``madvise()`` with ``MADV_COLD`` or ``MADV_PAGEOUT`` for the cold objects.
+Using both together would be also worth trying.
+
+A previous work [1]_ using the ``mlock()`` achieved up to 2.55x performance
+speedup.
+
+Let's see another realistic example access pattern for this kind of
+optimizations. Below are the visualized access patterns of streamcluster
+workload in PARSEC3 benchmark suite. We can easily see a 100 MiB sized memory
+object is the hot object.

+
+
+Personalized DAMON Application
+------------------------------
+
+Below approaches will work well for many cases, but would not be able to
+squeeze the last benefit in some special cases because only very simple
+optimizations are available.
+
+If this is the case, it might be the time to forget the comfortable use of the
+user space tool and dive into the debugfs interface (refer to :doc:`usage` for
+the detail) of DAMON. Using the interface, you can control the DAMON more
+flexibly. Therefore, you can write your personalized DAMON application that
+controls the monitoring via the debugfs interface, analyzes the result, and
+apply complex optimizations itself. Using this, you will be able to make more
+creative and wise optimizations.
+
+If you are kernel space programmer, writing kernel space DAMON applications
+using the API (refer to :doc:`api` for more detail) would be also an option.
+
+
+Reference Practices
+===================
+
+Referencing previously done successful practices could help you getting the
+sense for this kind of optimizations. There is an academic paper [1]_
+previously reported the visualized access pattern and `Manual Program
+Optimization`_ results for a number of realistic workloads. You can also get
+the visualized access pattern [4]_, [5]_, [6]_ and `Automated DAMON-based
+Memory Operations`_ results for other realistic workloads that collected with
+latest version of DAMON [2]_, [3]_.

+==========================
+DAMON: Data Access MONitor
+==========================
+
+DAMON is a data access monitoring framework subsystem for the Linux kernel.
+The core mechanisms of DAMON called 'region based sampling' and 'adaptive
+regions adjustment' (refer to :doc:`mechanisms` for the detail) make it
+
+ - *accurate* (The monitored information is useful for DRAM level memory
+ management; It might not appropriate for Cache-level accuracy, though),
+ - *ligfht-weight* (The monitoring overhead is low enough to be applied online
+ while making no impact on the performance of the target workloads), and
+ - *scalable* (The upper-bound of the instrumentation overhead is controllable
+ regardless of the size of target workloads).
+
+Using this framework, therefore, the kernel's core memory management mechanisms
+including reclamation and THP can be optimized for better memory management.
+The experimental memory management optimization works that incurring high

+==========
+Mechanisms
+==========
+
+This document describes the core mechanisms of DAMON and the five knobs for
+tuning, that is, ``sampling interval``, ``aggregation interval``, ``regions
+update interval``, ``minimum number of regions``, and ``maximum number of
+regions``.
+
+
+Basic Access Check
+==================
+
+The output of DAMON says what pages are how frequently accessed for a given
+duration. The resolution of the access frequency is controlled by setting
+``sampling interval`` and ``aggregation interval``. In detail,
+DAMON checks access to each page per ``sampling interval``, aggregates the
+results. In other words, counts the number of the accesses to each page.
+After each ``aggregation interval`` passes, DAMON signals users to read and
+save the aggregated access frequency if they want and then clears those. For
+the access check of each page, DAMON uses the Accessed bits of PTEs. This can
+be described in below simple pseudo-code::
+
+ while monitoring_on:
+ for page in monitoring_target:
+ if accessed(page):
+ nr_accesses[page] += 1
+ if time() % aggregation_interval == 0:
+ for page in monitoring_target:
+ nr_accesses[page] = 0
+ sleep(sampling interval)
+
+The monitoring overhead of this mechanism will arbitrarily increase as the
+size of the target workload grows.
+
+
+Region Based Sampling
+=====================
+
+To avoid the unbounded increase of the overhead, DAMON groups adjacent pages
+that assumed to have the same access frequencies into a region. As long as the
+assumption (pages in a region have the same access frequencies) is kept, only
+one page in the region is required to be checked. Thus, for each ``sampling
+interval``, DAMON randomly picks one page in each region, waits for one
+``sampling interval``, checks whether the page is accessed meanwhile, and
+increases the access frequency of the region if so. Therefore, the monitoring
+overhead is controllable by setting the number of regions. DAMON allows users
+to set the minimum and the maximum number of regions for the trade-off.
+
+This scheme, however, cannot preserve the quality of the output if the
+assumption is not guaranteed.
+
+
+Adaptive Regions Adjustment
+===========================
+
+At the beginning of the monitoring, DAMON constructs the initial regions by
+evenly splitting the monitoring target memory region into the user-specified
+minimum number of regions. In this initial state, the assumption is normally
+not kept and therefore the quality would be low. To keep the assumption as
+much as possible, DAMON adaptively merges and splits each region based on their
+access frequency.
+
+For each ``aggregation interval``, it compares the access frequencies of
+adjacent regions and merges those if the frequency difference is small. Then,
+after it reports and clears the aggregated access frequency of each region, it
+splits each region into two or three regions if the total number of regions
+will not exceed the user-specified maximum number of regions after the split.
+
+In this way, DAMON provides its best-effort quality and minimal overhead while
+keeping the bounds users set for their trade-off.
+
+
+Handling Virtual Memory Mappings
+================================
+
+This is for monitoring of virtual memory address space only. It is the only
+one address space that supported by DAMON as of now, but other address spaces
+will be supported in the future.
+
+Only small parts in the super-huge virtual address space of the processes are
+mapped to physical memory and accessed. Thus, tracking the unmapped address
+regions is just wasteful. However, because DAMON can deal with some level of
+noise using the adaptive regions adjustment mechanism, tracking every mapping
+is not strictly required but could even incur a high overhead in some cases.
+That said, too huge unmapped areas inside the monitoring target should be
+removed to not take the time for the adaptive mechanism.
+
+For the reason, DAMON converts the complex mappings to three distinct regions
+that cover every mapped area of the address space. Also, the two gaps between
+the three regions are the two biggest unmapped areas in the given address
+space. The two biggest unmapped areas might be the gap between the heap and
+the uppermost mmap()-ed region, and the gap between the lowermost mmap()-ed
+region and the stack will be two biggest unmapped regions. Because these gaps
+are exceptionally huge areas in usual address space, excluding these two
+biggest unmapped regions will be sufficient to make a trade-off. Below shows
+this in detail::
+
+ <heap>
+ <BIG UNMAPPED REGION 1>
+ <uppermost mmap()-ed region>
+ (small mmap()-ed regions and munmap()-ed regions)
+ <lowermost mmap()-ed region>
+ <BIG UNMAPPED REGION 2>
+ <stack>
+
+To further minimize dynamic mapping changes applying overhead, DAMON checks the
+dynamic memory mapping changes and applies it to the abstracted target area
+only for each of a user-specified time interval (``regions update interval``).

+Future Plans
+============
+
+DAMON is still on its first stage. Below plans are still under development.
+
+
+Automate Data Access Monitoring-based Memory Operation Schemes Execution
+========================================================================
+
+The ultimate goal of DAMON is being used as a building block of the data access
+pattern aware kernel memory management subsystem optimization. However, as
+always, some users having very special workloads will want to do their
+optimization. DAMON will automate most of the tasks for such manual
+optimizations soon. Users will be required to only describe what kind of data
+access pattern-based operation schemes they want in a simple form.
+
+By applying a very simple scheme for THP promotion/demotion with a prototype
+implementation, DAMON reduced 60% of THP memory footprint overhead while
+preserving 50% of the THP performance benefit. The detailed results can be
+seen on an external web page [1]_.
+
+Several RFC patchsets for this plan are available [2]_.
+
+
+Support Various Address Spaces
+==============================
+
+Currently, DAMON supports only virtual memory address spaces because it
+utilizes PTE Accessed bits as its low-level access check primitive and ``struct
+vma`` as a way to address the monitoring target regions. However, the core
+idea of DAMON is in a separate higher layer. Therefore, DAMON can support
+other various address spaces by changing the two low primitives to others for
+the address spaces.
+
+In the future, DAMON will make the lower level primitives configurable so that
+it can support various address spaces including physical memory. The
+configuration will be highly flexible so that users can even implement the
+primitives by themselves for their special use cases. Monitoring of
+clean/dirty/entire page cache, NUMA nodes, specific files, or block devices
+would be examples of such use cases.
+
+An RFC patchset for this plan is available [3]_.

+===============
+Getting Started
+===============
+
+This document briefly describes how you can use DAMON by demonstrating the user
+space tool. Please note that this document describes only a part of the
+features for brevity. Please refer to :doc:`usage` for more details.
+
+
+TL; DR
+======
+
+Simply follow below 5 commands. Don't forget replacing ``<your workload>``
+with your *real* workload, though. ::
+
+ $ git clone https://github.com/sjp38/linux -b damon/master
+ /* build the kernel with CONFIG_DAMON=y, install, reboot */
+ $ cd linux/tools/damon
+ $ ./damo record $(pidof <your workload>)
+ $ ./damo report heats --heatmap access_pattern.pdf
+ $ ./damo report wss --range 0 101 1 --plot wss_dist.pdf
+
+
+Prerequisites
+=============
+
+Kernel
+------
+
+You should first ensure your system is running on a kernel built with
+``CONFIG_DAMON``. If the value is set as ``m``, you should load the module
+first::
+
+ # modprobe damon
+
+
+User Space Tool
+---------------
+
+For the demonstration, we will use a user space tool for the convenient use of
+DAMON, called DAMON Operator (DAMO). It is located at ``tools/damon/damo`` of
+the kernel source tree. We assume that you set ``$PATH`` to point it. The
+``$PATH`` setting is not mandatory but we make the assumption here for the
+brevity of the below examples.
+
+Because DAMO is using the debugfs interface (refer to :doc:`usage` for the
+detail) of DAMON, you should also ensure debugfs is mounted. Mount it manually
+as below::
+
+ # mount -t debugfs none /sys/kernel/debug/
+
+or append below line to your ``/etc/fstab`` file so that your system can
+automatically mount debugfs from next booting::
+
+ debugfs /sys/kernel/debug debugfs defaults 0 0
+
+
+Recording Data Access Patterns
+==============================
+
+Below commands record memory access pattern of a program, ``masim``, and save
+it in a file, ``damon.data``. The program will access two 100 MiB memory
+regions one by one. ::
+
+ $ git clone https://github.com/sjp38/masim
+ $ cd masim; make; ./masim ./configs/zigzag.cfg &
+ $ sudo damo record -o damon.data $(pidof masim)
+
+The first two lines of commands start the monitoring target process in the
+background. You can substitute this with your real workload. The last line
+asks ``damo record`` to record the access pattern.
+
+
+Visualizing Recorded Patterns
+=============================
+
+Below three commands visualize the recorded access patterns into three
+image files, ``access_pattern_heatmap.png``, ``wss_dist.png``, and
+``wss_chron_change.png``. ::
+
+ $ damo report heats --heatmap -i damon.data access_pattern_heatmap.png
+ $ damo report wss --range 0 101 1 --plot wss_dist.png
+ $ damo report wss --range 0 101 1 --sortby time --plot wss_chron_change.png
+
+- ``access_pattern_heatmap.png`` will show the data access pattern in a
+ heatmap, which shows when (x-axis) what memory region (y-axis) is how
+ frequently accessed (color).
+- ``wss_dist.png`` will show the distribution of the working set size.
+- ``wss_chron_change.png`` will show how the working set size has
+ chronologically changed.
+
+Below are the three images. You can show those made with other realistic
+workloads at external web pages [1]_ [2]_ [3]_.

+Detailed Usages
+===============
+
+DAMON provides below three interfaces for various use cases.
+
+- *DAMON user space tool.*
+ This is for privileged people such as system administrators who want a
+ just-working human-friendly interface. This interface is a reference
+ implementation of the DAMON debugfs wrapper user space tool. Using this
+ tool, you can easily use the DAMON’s major features in a human-friendly way,
+ though it may not be highly tuned for your specific use-cases.
+- *debugfs interface.*
+ This is for user space programmers who want optimized use of DAMON. Using
+ this interface, you can use DAMON’s major features by reading from and
+ writing to specific debugfs files. Of course, you can write and use your
+ personalized DAMON debugfs wrapper user space tool that reads/writes the
+ debugfs files instead of you and provides a more human-friendly interface.
+- *Kernel Space Programming Interface.*
+ This is for kernel space programmers. Using this, you can utilize every
+ feature of DAMON most flexibly and efficiently by writing kernel space
+ DAMON application programs for you.
+
+We recommend you to start with the DAMON user space tool and move to debugfs
+interface only if the real requirement is found, and prohibit the use of the
+kernel space programming interface unless you need it, for the following
+reasons. First of all, there will be no big difference between the overheads
+of these three interfaces, unless the use case is so special. Also, all these
+three interfaces support all major features of DAMON.
+
+This document, therefore, does not describe the kernel space programming
+interface in detail. For the programming interface, please refer to :doc:`api`
+or ``include/linux/damon.h`` file in the kernel source tree.
+
+
+
+User Space Tool for DAMON
+=========================
+
+A reference implementation of the DAMON user space tool which provides a
+convenient user interface is located at ``tools/damon/damo`` in the kernel
+source tree. Please note that this is initially aimed to be used for minimal
+reference of the DAMON's debugfs interfaces and for tests of the DAMON itself.
+Based on the debugfs interface, you can create another cool and more convenient
+user space tools.
+
+The interface of the tool is basically subcommand based. You can almost always
+use ``-h`` option to get the help of the use of each subcommand. Currently, it
+supports two subcommands, ``record`` and ``report``.
+
+Below example commands assume you set ``$PATH`` to points ``tools/damon/`` for
+brevity. It is not mandatory for use of ``damo``, though.
+
+
+Recording Data Access Pattern
+-----------------------------
+
+The ``record`` subcommand records the data access pattern of target processes
+in a file (``./damon.data`` by default). You can specify the target as either
+pid of running target or a command for execution of the process. Below example
+shows a command target usage::
+
+ # cd <kernel>/tools/damon/
+ # damo record "sleep 5"
+
+The tool will execute ``sleep 5`` by itself and record the data access patterns
+of the process. Below example shows a pid target usage::
+
+ # sleep 5 &
+ # damo record `pidof sleep`
+
+You can tune this by setting the monitoring attributes and path to the record
+file using optional arguments to the subcommand. To know about the monitoring
+attributes in detail, please refer to :doc:`mechanisms`.
+
+
+Analyzing Data Access Pattern
+-----------------------------
+
+The ``report`` subcommand reads a data access pattern record file (if not
+explicitly specified, reads ``./damon.data`` file by default) and generates
+human-readable reports of various types. You can specify what type of report
+you want using a sub-subcommand to ``report`` subcommand. ``raw``, ``heats``,
+and ``wss`` report types are supported for now.
+
+
+raw
+~~~
+
+``raw`` sub-subcommand simply transforms the binary record into human-readable
+text. For example::
+
+ $ damo report raw
+ start_time: 193485829398
+ rel time: 0
+ nr_tasks: 1
+ pid: 1348
+ nr_regions: 4
+ 560189609000-56018abce000( 22827008): 0
+ 7fbdff59a000-7fbdffaf1a00( 5601792): 0
+ 7fbdffaf1a00-7fbdffbb5000( 800256): 1
+ 7ffea0dc0000-7ffea0dfd000( 249856): 0
+
+ rel time: 100000731
+ nr_tasks: 1
+ pid: 1348
+ nr_regions: 6
+ 560189609000-56018abce000( 22827008): 0
+ 7fbdff59a000-7fbdff8ce933( 3361075): 0
+ 7fbdff8ce933-7fbdffaf1a00( 2240717): 1
+ 7fbdffaf1a00-7fbdffb66d99( 480153): 0
+ 7fbdffb66d99-7fbdffbb5000( 320103): 1
+ 7ffea0dc0000-7ffea0dfd000( 249856): 0
+
+The first line shows the recording started timestamp (nanosecond). Records of
+data access patterns are following this. Each record is separated by a blank
+line. Each record first specifies the recorded time (``rel time``), the number
+of monitored tasks in this record (``nr_tasks``). A numbers of records of data
+access patterns for each task follow. Each data access pattern for each task
+shows it's pid (``pid``) and a number of monitored virtual address regions in
+this access pattern (``nr_regions``) first. After that, each line shows the
+start/end address, size, and the number of monitored accesses to the region for
+each of the regions.
+
+
+heats
+~~~~~
+
+The ``raw`` output is very detailed but hard to manually read and analyze.
+``heats`` sub-subcommand plots the data in 3-dimensional form, which represents
+the time in x-axis, virtual address in y-axis, and the access frequency in
+z-axis. Users can set the resolution of the map (``--tres`` and ``--ares``)
+and start/end point of each axis (``--tmin``, ``--tmax``, ``--amin``, and
+``--amax``) via optional arguments. For example::
+
+ $ damo report heats --tres 3 --ares 3
+ 0 0 0.0
+ 0 7609002 0.0
+ 0 15218004 0.0
+ 66112620851 0 0.0
+ 66112620851 7609002 0.0
+ 66112620851 15218004 0.0
+ 132225241702 0 0.0
+ 132225241702 7609002 0.0
+ 132225241702 15218004 0.0
+
+This command shows a recorded access pattern in heatmap of 3x3 resolution.
+Therefore it shows 9 data points in total. Each line shows each of the data
+points. The three numbers in each line represent time in nanosecond, virtual
+address in bytes, and the observed access frequency.
+
+Users can easily convert this text output into a heatmap image (represent z-axis
+values with colors) or other 3D representations using various tools such as
+'gnuplot'. ``heats`` sub-subcommand also provides 'gnuplot' based heatmap
+image creation. For this, you can use ``--heatmap`` option. Also, note that
+because it uses 'gnuplot' internally, it will fail if 'gnuplot' is not
+installed on your system. For example::
+
+ $ ./damo report heats --heatmap heatmap.png
+
+Creates ``heatmap.png`` file containing the heatmap image. It supports
+``pdf``, ``png``, ``jpeg``, and ``svg``.
+
+If the target address space is virtual memory address space and you plot the
+entire address space, the huge unmapped regions will make the picture looks
+only black. Therefore you should do proper zoom in / zoom out using the axis
+boundary-setting optional arguments. To make this effort minimal, you can use
+``--guide`` option. For example::
+
+ $ ./damo report heats --guide
+ pid:1348
+ time: 193485829398-198337863555 (4852034157)
+ region 0: 00000094564599762944-00000094564622589952 (22827008)
+ region 1: 00000140454009610240-00000140454016012288 (6402048)
+ region 2: 00000140731597193216-00000140731597443072 (249856)
+
+The output shows unions of monitored regions (start and end addresses in byte)
+and union of monitored time duration (start and end time in nanoseconds) of
+each target task. Therefore, it would be wise to plot the data points in each
+union. If no axis boundary option is given, it will automatically find the
+biggest union in ``--guide`` output and plot for it.
+
+
+wss
+~~~
+
+The ``wss`` type extracts the distribution and chronological working set size
+changes from the records. For example::
+
+ $ ./damo report wss
+ # <percentile> <wss>
+ # pid 1348
+ # avr: 66228
+ 0 0
+ 25 0
+ 50 0
+ 75 0
+ 100 1920615
+
+Without any option, it shows the distribution of the working set sizes as
+above. It shows 0th, 25th, 50th, 75th, and 100th percentile and the average of
+the measured working set sizes in the access pattern records. In this case,
+the working set size was zero for 75th percentile but 1,920,615 bytes in max
+and 66,228 bytes on average.
+
+By setting the sort key of the percentile using '--sortby', you can show how
+the working set size has chronologically changed. For example::
+
+ $ ./damo report wss --sortby time
+ # <percentile> <wss>
+ # pid 1348
+ # avr: 66228
+ 0 0
+ 25 0
+ 50 0
+ 75 0
+ 100 0
+
+The average is still 66,228. And, because the access was spiked in very short
+duration but we use only 4 data points, we cannot show when the access spikes
+made. Users can specify the resolution of the distribution (``--range``). By
+giving more fine resolution, users will be able to see the short duration
+spikes.
+
+Similar to that of ``heats --heatmap``, it also supports 'gnuplot' based simple
+visualization of the distribution via ``--plot`` option.
+
+
+debugfs Interface
+=================
+
+DAMON exports four files, ``attrs``, ``pids``, ``record``, and ``monitor_on``
+under its debugfs directory, ``<debugfs>/damon/``.
+
+
+Attributes
+----------
+
+Users can get and set the ``sampling interval``, ``aggregation interval``,
+``regions update interval``, and min/max number of monitoring target regions by
+reading from and writing to the ``attrs`` file. To know about the monitoring
+attributes in detail, please refer to :doc:`mechanisms`. For example, below
+commands set those values to 5 ms, 100 ms, 1,000 ms, 10 and 1000, and then
+check it again::
+
+ # cd <debugfs>/damon
+ # echo 5000 100000 1000000 10 1000 > attrs
+ # cat attrs
+ 5000 100000 1000000 10 1000
+
+
+Target PIDs
+-----------
+
+Users can get and set the pids of monitoring target processes by reading from
+and writing to the ``pids`` file. For example, below commands set processes
+having pids 42 and 4242 as the processes to be monitored and check it again::
+
+ # cd <debugfs>/damon
+ # echo 42 4242 > pids
+ # cat pids
+ 42 4242
+
+Note that setting the pids doesn't start the monitoring.
+
+
+Record
+------
+
+This debugfs file allows you to record monitored access patterns in a regular
+binary file. The recorded results are first written to an in-memory buffer and
+flushed to a file in batch. Users can get and set the size of the buffer and
+the path to the result file by reading from and writing to the ``record`` file.
+For example, below commands set the buffer to be 4 KiB and the result to be
+saved in ``/damon.data``. ::
+
+ # cd <debugfs>/damon
+ # echo "4096 /damon.data" > record
+ # cat record
+ 4096 /damon.data
+
+
+Turning On/Off
+--------------
+
+Setting the attributes as described above doesn't incur effect unless you
+explicitly start the monitoring. You can start, stop, and check the current
+status of the monitoring by writing to and reading from the ``monitor_on``
+file. Writing ``on`` to the file make DAMON start monitoring of the target
+processes with the attributes. Recording will also start if requested before.
+Writing ``off`` to the file stops those. DAMON also stops if every target
+process is terminated. Below example commands turn on, off, and check the
+status of DAMON::
+
+ # cd <debugfs>/damon
+ # echo on > monitor_on
+ # echo off > monitor_on
+ # cat monitor_on
+ off
+
+Please note that you cannot write to the above-mentioned debugfs files while
+the monitoring is turned on. If you write to the files while DAMON is running,
+an error code such as ``-EBUSY`` will be returned.

From: SeongJae Park <[email protected]>
This commit adds a shallow wrapper python script, ``/tools/damon/damo``
that provides more convenient interface. Note that it is only aimed to
be used for minimal reference of the DAMON's debugfs interfaces and for
debugging of the DAMON itself.

Last week, this patchset received 5 'Reviewed-by' tags, but no further comments
for changes. I updated the documentation, but the change is only small. For
the reason, I'm only asking more reviews rather than posting the whole series
again. Any comment is welcome.
Thanks,
SeongJae Park

This is on my review TODO list and I will get to it in a couple of
days. No need to post new versions.
