 ## Usage
-### Basic example
-```
-xmrig.exe -o pool.monero.hashvault.pro:5555 -u YOUR_WALLET -p x -k
-```
-
-### Failover
-```
-xmrig.exe -o pool.monero.hashvault.pro:5555 -u YOUR_WALLET1 -p x -k -o pool.supportxmr.com:5555 -u YOUR_WALLET2 -p x -k
-```
-For failover you can add multiple pools, maximum count not limited.
+Preferend way to configure miner is [JSON config file](src/config.json) as more flexible and human frendly, command line interface not cover all features, for example mining profiles for different algorithms. Most impotant options can be changed in runtime without miner restart by editing config or via API.

-Also you can use configuration via config file, default **config.json**. You can load multiple config files and combine it with command line options.
-
-## Algorithm variations
-Since version 0.8.0.
-* `--av=1` For CPUs with hardware AES.
-* `--av=2` Lower power mode (double hash) of `1`.
-* `--av=3` Software AES implementation.
-* `--av=4` Lower power mode (double hash) of `3`.
-
-## Common Issues
-### HUGE PAGES unavailable
-* Run XMRig as Administrator.
-* Since version 0.8.0 XMRig automatically enables SeLockMemoryPrivilege for current user, but reboot or sign out still required. [Manual instruction](https://msdn.microsoft.com/en-gb/library/ms190730.aspx).
-
-## Other information
-* No HTTP support, only stratum protocol support.
-* No TLS support.
-* Default donation 5% (5 minutes in 100 minutes) can be reduced to 1% via command line option `--donate-level`.
-
-
-### CPU mining performance
-* **Intel i7-7700** - 307 H/s (4 threads)
-* **AMD Ryzen 7 1700X** - 560 H/s (8 threads)
-
-Please note performance is highly dependent on system load. The numbers above are obtained on an idle system. Tasks heavily using a processor cache, such as video playback, can greatly degrade hashrate. Optimal number of threads depends on the size of the L3 cache of a processor, 1 thread requires 2 MB of cache.
-
-### Maximum performance checklist
-* Idle operating system.
-* Do not exceed optimal thread count.
-* Use modern CPUs with AES-NI instruction set.
-* Try setup optimal cpu affinity.
-* Enable fast memory (Large/Huge pages).
-
 ## Donations
+* Default donation 5% (5 minutes in 100 minutes) can be reduced to 1% via option `donate-level` or disabled in source code.

+Since version 3 mining [algorithm](#algorithm-names) should specified for each pool separately (`algo` option), earlier versions was use one global `algo` option and per pool `variant` option (this option was removed in v3). If your pool support [mining algorithm negotiation](https://github.com/xmrig/xmrig-proxy/issues/168) you may not specify this option at all.

+# HTTP API
+
+If you want use HTTP API you need enable it (`"enabled": true,`) then choice `port` and optionaly `host`. API not available if miner built without HTTP support (`-DWITH_HTTP=OFF`).
+
+Offical HTTP client for API: http://workers.xmrig.info/
+
+Example configuration:
+
+```json
+"api": {
+	"id": null,
+	"worker-id": null,
+},
+"http": {
+	"enabled": false,
+	"host": "127.0.0.1",
+	"port": 0,
+	"access-token": null,
+	"restricted": true
+}
+```
+
+#### Global API options
+* **id** Miner ID, if not set created automatically.
+* **worker-id** Optional worker name, if not set will be detected automatically.
+
+#### HTTP API options,
+* **enabled** Enable (`true`) or disable (`false`) HTTP API.
+* **host** Host for incoming connections `http://<host>:<port>`, to allow connections from all interfaces use `0.0.0.0` (IPv4) or `::` (IPv4+IPv6).
+* **port** Port for incoming connections `http://<host>:<port>`, zero port is valid option and means random port.
+* **access-token** [Bearer](https://gist.github.com/xmrig/c75fdd1f8e0f3bac05500be2ab718f8e#file-api-html-L54) access token to secure access to API. Miner support this token only via `Authorization` header.
+* **restricted** Use `false` to allow remote configuration.
+
+If you prefer use command line options instead of config file, you can use options: `--api-id`, `--api-worker-id`, `--http-enabled`, `--http-host`, `--http-access-token`, `--http-port`, `--http-no-restricted`.
+
+Versions before 2.15 was use another options for API https://github.com/xmrig/xmrig/issues/1007
+
+## Endpoints
+
+### GET /1/summary
+
+Get miner summary information. [Example](api/1/summary.json).
+
+### GET /1/threads
+
+Get detailed information about miner threads. [Example](api/1/threads.json).
+
+
+## Restricted endpoints
+
+All API endpoints below allow access to sensitive information and remote configure miner. You should set `access-token` and allow unrestricted access (`"restricted": false`).
+
+### GET /1/config
+
+Get current miner configuration. [Example](api/1/config.json).
+
+
+### PUT /1/config
+
+Update current miner configuration. Common use case, get current configuration, make changes, and upload it to miner.
+
+Curl example:
+
+```
+curl -v --data-binary @config.json -X PUT -H "Content-Type: application/json" -H "Authorization: Bearer SECRET" http://127.0.0.1:44444/1/config

+# CPU backend
+
+All CPU related settings contains in one `cpu` object in config file, CPU backend allow specify multiple profiles and allow switch between them without restrictions by pool request or config change. Default auto-configuration create reasonable minimum of profiles which cover all supported algorithms.
+
+### Example
+
+Example below demonstrate all primary ideas of flexible profiles configuration:
+
+* `"rx/wow"` Exact match to algorithm `rx/wow`, defined 4 threads without CPU affinity.
+* `"cn"` Default failback profile for all `cn/*` algorithms, defined 2 threads with CPU affinity, another failback profiles is `cn-lite`, `cn-heavy` and `rx`.
+* `"cn-lite"` Default failback profile for all `cn-lite/*` algorithms, defined 2 double threads with CPU affinity.
+* `"cn-pico"` Alternative short object format.
+* `"custom-profile"` Custom user defined profile.
+* `"*"` Failback profile for all unhandled by other profiles algorithms.
+* `"cn/r"` Exact match, alias to profile `custom-profile`.
+* `"cn/0"` Exact match, disabled algorithm.
+
+```json

+        "cn/0": false
+    }
+}
+```
+
+## Threads definition
+Threads can be defined in 3 formats.
+
+#### Array format
+```json
+[
+    [1, 0],
+    [1, 2],
+    [1, -1],
+    [2, -1]
+]
+```
+Each line represent one thread, first element is intensity, this option was known as `low_power_mode`, possible values is range from 1 to 5, second element is CPU affinity, special value `-1` means no affinity.
+
+#### Short array format
+```json
+[-1, -1, -1, -1]
+```
+Each number represent one thread and means CPU affinity, this is default format for algorithm with maximum intensity 1, currently it all RandomX variants and cryptonight-gpu.
+
+#### Short object format
+```json
+{
+    "intensity": 2,
+    "threads": 8,
+    "affinity": -1
+}
+```
+Internal format, but can be user defined.
+
+## Shared options
+
+#### `enabled`
+Enable (`true`) or disable (`false`) CPU backend, by default `true`.
+
+#### `huge-pages`
+Enable (`true`) or disable (`false`) huge pages support, by default `true`.
+
+#### `hw-aes`
+Force enable (`true`) or disable (`false`) hardware AES support. Default value `null` means miner autodetect this feature. Usually don't need change this option, this option useful for some rare cases when miner can't detect hardware AES, but it available. If you force enable this option, but your hardware not support it, miner will crash.
+
+#### `priority`
+Mining threads priority, value from `1` (lowest priority) to `5` (highest possible priority). Default value `null` means miner don't change threads priority at all.
+
+#### `asm`
+Enable/configure or disable ASM optimizations. Possible values: `true`, `false`, `"intel"`, `"ryzen"`, `"bulldozer"`.
+
+#### `argon2-impl` (since v3.1.0)
+Allow override automatically detected Argon2 implementation, this option added mostly for debug purposes, default value `null` means autodetect. Other possible values: `"x86_64"`, `"SSE2"`, `"SSSE3"`, `"XOP"`, `"AVX2"`, `"AVX-512F"`. Manual selection has no safe guards, if you CPU not support required instuctions, miner will crash.

+# Argon2 [![Build Status](https://travis-ci.org/WOnder93/argon2.svg?branch=master)](https://travis-ci.org/WOnder93/argon2)
+A multi-arch library implementing the Argon2 password hashing algorithm.
+
+This project is based on the [original source code](https://github.com/P-H-C/phc-winner-argon2) by the Argon2 authors. The goal of this project is to provide efficient Argon2 implementations for various HW architectures (x86, SSE, ARM, PowerPC, ...).
+
+For the x86_64 architecture, the library implements a simple CPU dispatch which automatically selects the best implementation based on CPU flags and quick benchmarks.
+
+# Building
+## Using GNU autotools
+
+To prepare the build environment, run:
+```bash
+autoreconf -i
+./configure
+```
+
+After that, just run `make` to build the library.
+
+### Running tests
+After configuring the build environment, run `make check` to run the tests.
+
+### Architecture options
+You can specify the target architecture by passing the `--host=...` flag to `./configure`.
+
+Supported architectures:
+ * `x86_64` – 64-bit x86 architecture
+ * `generic` – use generic C impementation
+
+## Using CMake
+
+To prepare the build environment, run:
+```bash
+cmake -DCMAKE_BUILD_TYPE=Release .
+```
+
+Then you can run `make` to build the library.
+
+## Using QMake/Qt Creator
+A [QMake](http://doc.qt.io/qt-4.8/qmake-manual.html) project is also available in the `qmake` directory. You can open it in the [Qt Creator IDE](http://wiki.qt.io/Category:Tools::QtCreator) or build it from terminal:
+```bash
+cd qmake
+# see table below for the list of possible ARCH and CONFIG values
+qmake ARCH=... CONFIG+=...
+make
+```
+
+### Architecture options
+For QMake builds you can configure support for different architectures. Use the `ARCH` variable to choose the architecture and the `CONFIG` variable to set additional options.
+
+Supported architectures:
+ * `x86_64` – 64-bit x86 architecture
+   * QMake config flags:
+     * `USE_SSE2` – use SSE2 instructions
+     * `USE_SSSE3` – use SSSE3 instructions
+     * `USE_XOP` – use XOP instructions
+     * `USE_AVX2` – use AVX2 instructions
+     * `USE_AVX512F` – use AVX-512F instructions
+ * `generic` – use generic C impementation

+ * Example code for a decoder and encoder of "hash strings", with Argon2
+ * parameters.
+ *
+ * This code comprises three sections:
+ *
+ *   -- The first section contains generic Base64 encoding and decoding
+ *   functions. It is conceptually applicable to any hash function
+ *   implementation that uses Base64 to encode and decode parameters,
+ *   salts and outputs. It could be made into a library, provided that
+ *   the relevant functions are made public (non-static) and be given
+ *   reasonable names to avoid collisions with other functions.
+ *
+ *   -- The second section is specific to Argon2. It encodes and decodes
+ *   the parameters, salts and outputs. It does not compute the hash
+ *   itself.
+ *
+ * The code was originally written by Thomas Pornin <pornin@bolet.org>,
+ * to whom comments and remarks may be sent. It is released under what
+ * should amount to Public Domain or its closest equivalent; the
+ * following mantra is supposed to incarnate that fact with all the

+HTTP Parser
+===========
+
+[![Build Status](https://api.travis-ci.org/nodejs/http-parser.svg?branch=master)](https://travis-ci.org/nodejs/http-parser)
+
+This is a parser for HTTP messages written in C. It parses both requests and
+responses. The parser is designed to be used in performance HTTP
+applications. It does not make any syscalls nor allocations, it does not
+buffer data, it can be interrupted at anytime. Depending on your
+architecture, it only requires about 40 bytes of data per message
+stream (in a web server that is per connection).
+
+Features:
+
+  * No dependencies
+  * Handles persistent streams (keep-alive).
+  * Decodes chunked encoding.
+  * Upgrade support
+  * Defends against buffer overflow attacks.
+
+The parser extracts the following information from HTTP messages:
+
+  * Header fields and values
+  * Content-Length
+  * Request method
+  * Response status code
+  * Transfer-Encoding
+  * HTTP version
+  * Request URL
+  * Message body
+
+
+Usage
+-----
+
+One `http_parser` object is used per TCP connection. Initialize the struct
+using `http_parser_init()` and set the callbacks. That might look something
+like this for a request parser:
+```c
+http_parser_settings settings;
+settings.on_url = my_url_callback;
+settings.on_header_field = my_header_field_callback;
+/* ... */
+
+http_parser *parser = malloc(sizeof(http_parser));
+http_parser_init(parser, HTTP_REQUEST);
+parser->data = my_socket;
+```
+
+When data is received on the socket execute the parser and check for errors.
+
+```c
+size_t len = 80*1024, nparsed;
+char buf[len];
+ssize_t recved;
+
+recved = recv(fd, buf, len, 0);
+
+if (recved < 0) {
+  /* Handle error. */
+}
+
+/* Start up / continue the parser.
+ * Note we pass recved==0 to signal that EOF has been received.
+ */
+nparsed = http_parser_execute(parser, &settings, buf, recved);
+
+if (parser->upgrade) {
+  /* handle new protocol */
+} else if (nparsed != recved) {
+  /* Handle error. Usually just close the connection. */
+}
+```
+
+`http_parser` needs to know where the end of the stream is. For example, sometimes
+servers send responses without Content-Length and expect the client to
+consume input (for the body) until EOF. To tell `http_parser` about EOF, give
+`0` as the fourth parameter to `http_parser_execute()`. Callbacks and errors
+can still be encountered during an EOF, so one must still be prepared
+to receive them.
+
+Scalar valued message information such as `status_code`, `method`, and the
+HTTP version are stored in the parser structure. This data is only
+temporally stored in `http_parser` and gets reset on each new message. If
+this information is needed later, copy it out of the structure during the
+`headers_complete` callback.
+
+The parser decodes the transfer-encoding for both requests and responses
+transparently. That is, a chunked encoding is decoded before being sent to
+the on_body callback.
+
+
+The Special Problem of Upgrade
+------------------------------
+
+`http_parser` supports upgrading the connection to a different protocol. An
+increasingly common example of this is the WebSocket protocol which sends
+a request like
+
+        GET /demo HTTP/1.1
+        Upgrade: WebSocket
+        Connection: Upgrade
+        Host: example.com
+        Origin: http://example.com
+        WebSocket-Protocol: sample
+
+followed by non-HTTP data.
+
+(See [RFC6455](https://tools.ietf.org/html/rfc6455) for more information the
+WebSocket protocol.)
+
+To support this, the parser will treat this as a normal HTTP message without a
+body, issuing both on_headers_complete and on_message_complete callbacks. However
+http_parser_execute() will stop parsing at the end of the headers and return.
+
+The user is expected to check if `parser->upgrade` has been set to 1 after
+`http_parser_execute()` returns. Non-HTTP data begins at the buffer supplied
+offset by the return value of `http_parser_execute()`.
+
+
+Callbacks
+---------
+
+During the `http_parser_execute()` call, the callbacks set in
+`http_parser_settings` will be executed. The parser maintains state and
+never looks behind, so buffering the data is not necessary. If you need to
+save certain data for later usage, you can do that from the callbacks.
+
+There are two types of callbacks:
+
+* notification `typedef int (*http_cb) (http_parser*);`
+    Callbacks: on_message_begin, on_headers_complete, on_message_complete.
+* data `typedef int (*http_data_cb) (http_parser*, const char *at, size_t length);`
+    Callbacks: (requests only) on_url,
+               (common) on_header_field, on_header_value, on_body;
+
+Callbacks must return 0 on success. Returning a non-zero value indicates
+error to the parser, making it exit immediately.
+
+For cases where it is necessary to pass local information to/from a callback,
+the `http_parser` object's `data` field can be used.
+An example of such a case is when using threads to handle a socket connection,
+parse a request, and then give a response over that socket. By instantiation
+of a thread-local struct containing relevant data (e.g. accepted socket,
+allocated memory for callbacks to write into, etc), a parser's callbacks are
+able to communicate data between the scope of the thread and the scope of the
+callback in a threadsafe manner. This allows `http_parser` to be used in
+multi-threaded contexts.
+
+Example:
+```c
+ typedef struct {
+  socket_t sock;
+  void* buffer;
+  int buf_len;
+ } custom_data_t;
+
+
+int my_url_callback(http_parser* parser, const char *at, size_t length) {
+  /* access to thread local custom_data_t struct.
+  Use this access save parsed data for later use into thread local
+  buffer, or communicate over socket
+  */
+  parser->data;
+  ...
+  return 0;
+}
+
+...
+
+void http_parser_thread(socket_t sock) {
+ int nparsed = 0;
+ /* allocate memory for user data */
+ custom_data_t *my_data = malloc(sizeof(custom_data_t));
+
+ /* some information for use by callbacks.
+ * achieves thread -> callback information flow */
+ my_data->sock = sock;
+
+ /* instantiate a thread-local parser */
+ http_parser *parser = malloc(sizeof(http_parser));
+ http_parser_init(parser, HTTP_REQUEST); /* initialise parser */
+ /* this custom data reference is accessible through the reference to the
+ parser supplied to callback functions */
+ parser->data = my_data;
+
+ http_parser_settings settings; /* set up callbacks */
+ settings.on_url = my_url_callback;
+
+ /* execute parser */
+ nparsed = http_parser_execute(parser, &settings, buf, recved);
+
+ ...
+ /* parsed information copied from callback.
+ can now perform action on data copied into thread-local memory from callbacks.
+ achieves callback -> thread information flow */
+ my_data->buffer;
+ ...
+}
+
+```
+
+In case you parse HTTP message in chunks (i.e. `read()` request line
+from socket, parse, read half headers, parse, etc) your data callbacks
+may be called more than once. `http_parser` guarantees that data pointer is only
+valid for the lifetime of callback. You can also `read()` into a heap allocated
+buffer to avoid copying memory around if this fits your application.
+
+Reading headers may be a tricky task if you read/parse headers partially.
+Basically, you need to remember whether last header callback was field or value
+and apply the following logic:
+
+    (on_header_field and on_header_value shortened to on_h_*)
+     ------------------------ ------------ --------------------------------------------
+    | State (prev. callback) | Callback   | Description/action                         |
+     ------------------------ ------------ --------------------------------------------
+    | nothing (first call)   | on_h_field | Allocate new buffer and copy callback data |
+    |                        |            | into it                                    |
+     ------------------------ ------------ --------------------------------------------
+    | value                  | on_h_field | New header started.                        |
+    |                        |            | Copy current name,value buffers to headers |
+    |                        |            | list and allocate new buffer for new name  |
+     ------------------------ ------------ --------------------------------------------
+    | field                  | on_h_field | Previous name continues. Reallocate name   |
+    |                        |            | buffer and append callback data to it      |
+     ------------------------ ------------ --------------------------------------------
+    | field                  | on_h_value | Value for current header started. Allocate |
+    |                        |            | new buffer and copy callback data to it    |
+     ------------------------ ------------ --------------------------------------------
+    | value                  | on_h_value | Value continues. Reallocate value buffer   |
+    |                        |            | and append callback data to it             |
+     ------------------------ ------------ --------------------------------------------
+
+
+Parsing URLs
+------------
+
+A simplistic zero-copy URL parser is provided as `http_parser_parse_url()`.
+Users of this library may wish to use it to parse URLs constructed from
+consecutive `on_url` callbacks.

+Introduction
+
+The Hardware Locality (hwloc) software project aims at easing the process of
+discovering hardware resources in parallel architectures. It offers
+command-line tools and a C API for consulting these resources, their locality,
+attributes, and interconnection. hwloc primarily aims at helping
+high-performance computing (HPC) applications, but is also applicable to any
+project seeking to exploit code and/or data locality on modern computing
+platforms.
+
+hwloc is actually made of two subprojects distributed together:
+
+  * The original hwloc project for describing the internals of computing nodes.
+ It is described in details starting at section Hardware Locality (hwloc)
+ Introduction.
+  * The network-oriented companion called netloc (Network Locality), described
+ in details starting with section Network Locality (netloc).
+
+See also the Related pages tab above for links to other sections.
+
+Netloc may be disabled, but the original hwloc cannot. Both hwloc and netloc
+APIs are documented after these sections.
+
+Installation
+
+hwloc (http://www.open-mpi.org/projects/hwloc/) is available under the BSD
+license. It is hosted as a sub-project of the overall Open MPI project (http://
+www.open-mpi.org/). Note that hwloc does not require any functionality from
+Open MPI -- it is a wholly separate (and much smaller!) project and code base.
+It just happens to be hosted as part of the overall Open MPI project.
+
+Basic Installation
+
+Installation is the fairly common GNU-based process:

+shell$ ./configure --prefix=...
+shell$ make
+shell$ make install
+
+hwloc- and netloc-specific configure options and requirements are documented in
+sections hwloc Installation and Netloc Installation respectively.
+
+Also note that if you install supplemental libraries in non-standard locations,
+hwloc's configure script may not be able to find them without some help. You
+may need to specify additional CPPFLAGS, LDFLAGS, or PKG_CONFIG_PATH values on
+the configure command line.
+
+For example, if libpciaccess was installed into /opt/pciaccess, hwloc's
+configure script may not find it be default. Try adding PKG_CONFIG_PATH to the
+./configure command line, like this:
+
+./configure PKG_CONFIG_PATH=/opt/pciaccess/lib/pkgconfig ...
+
+Running the "lstopo" tool is a good way to check as a graphical output whether
+hwloc properly detected the architecture of your node. Netloc command-line
+tools can be used to display the network topology interconnecting your nodes.
+
+Installing from a Git clone
+
+Additionally, the code can be directly cloned from Git:
+
+shell$ git clone https://github.com/open-mpi/hwloc.git
+shell$ cd hwloc
+shell$ ./autogen.sh
+
+Note that GNU Autoconf >=2.63, Automake >=1.11 and Libtool >=2.2.6 are required
+when building from a Git clone.
+
+Nightly development snapshots are available on the web site, they can be
+configured and built without any need for Git or GNU Autotools.
+
+Questions and Bugs
+
+Bugs should be reported in the tracker (https://github.com/open-mpi/hwloc/
+issues). Opening a new issue automatically displays lots of hints about how to
+debug and report issues.
+
+Questions may be sent to the users or developers mailing lists (http://
+www.open-mpi.org/community/lists/hwloc.php).
+
+There is also a #hwloc IRC channel on Freenode (irc.freenode.net).

+/** \defgroup hwlocality_bitmap The bitmap API
+ *
+ * The ::hwloc_bitmap_t type represents a set of integers (positive or null).
+ * A bitmap may be of infinite size (all bits are set after some point).
+ * A bitmap may even be full if all bits are set.
+ *
+ * Bitmaps are used by hwloc for sets of OS processors
+ * (which may actually be hardware threads) as by ::hwloc_cpuset_t
+ * (a typedef for ::hwloc_bitmap_t), or sets of NUMA memory nodes
+ * as ::hwloc_nodeset_t (also a typedef for ::hwloc_bitmap_t).
+ * Those are used for cpuset and nodeset fields in the ::hwloc_obj structure,
+ * see \ref hwlocality_object_sets.
+ *
+ * <em>Both CPU and node sets are always indexed by OS physical number.</em>
+ * However users should usually not build CPU and node sets manually
+ * (e.g. with hwloc_bitmap_set()).
+ * One should rather use existing object sets and combine them with
+ * hwloc_bitmap_or(), etc.
+ * For instance, binding the current thread on a pair of cores may be performed with:
+ * \code
+ * hwloc_obj_t core1 = ... , core2 = ... ;
+ * hwloc_bitmap_t set = hwloc_bitmap_alloc();
+ * hwloc_bitmap_or(set, core1->cpuset, core2->cpuset);
+ * hwloc_set_cpubind(topology, set, HWLOC_CPUBIND_THREAD);
+ * hwloc_bitmap_free(set);
+ * \endcode
+ *
+ * \note Most functions below return an int that may be negative in case of
+ * error. The usual error case would be an internal failure to realloc/extend
+ * the storage of the bitmap (\p errno would be set to \c ENOMEM).
+ *
+ * \note Several examples of using the bitmap API are available under the
+ * doc/examples/ directory in the source tree.
+ * Regression tests such as tests/hwloc/hwloc_bitmap*.c also make intensive use
+ * of this API.

+ *
+ * Applications that manipulate many similar topologies, for instance
+ * one for each node of a homogeneous cluster, may want to compress
+ * topologies to reduce the memory footprint.
+ *
+ * This file offers a way to manipulate the difference between topologies
+ * and export/import it to/from XML.
+ * Compression may therefore be achieved by storing one topology
+ * entirely while the others are only described by their differences
+ * with the former.
+ * The actual topology can be reconstructed when actually needed by
+ * applying the precomputed difference to the reference topology.
+ *
+ * This interface targets very similar nodes.
+ * Only very simple differences between topologies are actually
+ * supported, for instance a change in the memory size, the name
+ * of the object, or some info attribute.
+ * More complex differences such as adding or removing objects cannot
+ * be represented in the difference structures and therefore return
+ * errors.
+ * Differences between object sets or topology-wide allowed sets,
+ * cannot be represented either.
+ *
+ * It means that there is no need to apply the difference when
+ * looking at the tree organization (how many levels, how many
+ * objects per level, what kind of objects, CPU and node sets, etc)
+ * and when binding to objects.
+ * However the difference must be applied when looking at object
+ * attributes such as the name, the memory size or info attributes.
