 ## Usage
-The preferred way to configure the miner is the [JSON config file](src/config.json) as it is more flexible and human friendly. The command line interface does not cover all features, such as mining profiles for different algorithms. Important options can be changed during runtime without miner restart by editing the config file or executing API calls.

+# Embedded benchmark
+
+You can run with XMRig with the following commands:
+```
+xmrig --bench=1M
+xmrig --bench=10M
+xmrig --bench=1M -a rx/wow
+xmrig --bench=10M -a rx/wow
+```
+This will run between 1 and 10 million RandomX hashes, depending on `bench` parameter, and print the time it took. First two commands use Monero variant (2 MB per thread, best for Zen2/Zen3 CPUs), second two commands use Wownero variant (1 MB per thread, useful for Intel and 1st gen Zen/Zen+ CPUs).
+
+Checksum of all the hashes will be also printed to check stability of your hardware: if it's green then it's correct, if it's red then there was hardware error during computation. No Internet connection is required for the benchmark.
+
+Double check that you see `Huge pages 100%` both for dataset and for all threads, and also check for `msr register values ... has been set successfully` - without this result will be far from the best. Running as administrator is required for MSR and huge pages to be set up properly.
+
+![Benchmark example](https://i.imgur.com/PST3BYc.png)
+
+### Benchmark with custom config
+
+You can run benchmark with any configuration you want. Just start without command line parameteres, use regular config.json and add `"benchmark":"1M",` on the next line after pool url. 
+
+# Stress test
+
+You can also run continuous stress-test that is as close to the real RandomX mining as possible and doesn't require any configuration:
+```
+xmrig --stress
+xmrig --stress -a rx/wow
+```
+This will require Internet connection and will run indefinitely.

+Use AVX2 for dataset initialization. Faster on some CPUs. Auto-detect (`-1`), disabled (`0`), always enabled on CPUs that support AVX2 (`1`).
+
+#### `mode`
+RandomX mining mode: `auto`, `fast` (2 GB memory), `light` (256 MB memory).
+
+#### `1gb-pages`
+Use 1GB hugepages for RandomX dataset (Linux only). Enabled (`true`) or disabled (`false`). It gives 1-3% speedup.
+
+#### `wrmsr`
+[MSR mod](https://xmrig.com/docs/miner/randomx-optimization-guide/msr). Enabled (`true`) or disabled (`false`).

+#### `rdmsr`
+Restore MSR register values to their original values on exit. Used together with `wrmsr`. Enabled (`true`) or disabled (`false`).
+
+#### `cache_qos`

+
+#### `scratchpad_prefetch_mode`
+Which instruction to use in RandomX loop to prefetch data from scratchpad. `1` is default and fastest in most cases. Can be off (`0`), `prefetcht0` instruction (`1`), `prefetchnta` instruction (`2`, a bit faster on Coffee Lake and a few other CPUs), `mov` instruction (`3`).

+
+    Inspired by `gsl::span` and/or `boost::iterator_range`. This class is
+    intended to be used as a parameter type for functions that need to take a
+    writable or read-only sequence of data. Most common cases are `span<char>`
+    and `span<std::uint8_t>`. Using as a class member is only recommended if
+    clearly documented as not doing a deep-copy. C-arrays are easily convertible
+    to this type.
+
+    \note Conversion from C string literal to `span<const char>` will include
+      the NULL-terminator.
+    \note Never allows derived-to-base pointer conversion; an array of derived
+      types is not an array of base types.

+
+Features
+--------
+
+* Simple `format API <https://fmt.dev/latest/api.html>`_ with positional arguments
+  for localization
+* Implementation of `C++20 std::format
+  <https://en.cppreference.com/w/cpp/utility/format>`__
+* `Format string syntax <https://fmt.dev/latest/syntax.html>`_ similar to Python's
+  `format <https://docs.python.org/3/library/stdtypes.html#str.format>`_
+* Fast IEEE 754 floating-point formatter with correct rounding, shortness and
+  round-trip guarantees.
+* Safe `printf implementation
+  <https://fmt.dev/latest/api.html#printf-formatting>`_ including the POSIX
+  extension for positional arguments
+* Extensibility: `support for user-defined types
+  <https://fmt.dev/latest/api.html#formatting-user-defined-types>`_
+* High performance: faster than common standard library implementations of
+  ``(s)printf``, iostreams, ``to_string`` and ``to_chars``, see `Speed tests`_
+  and `Converting a hundred million integers to strings per second
+  <http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html>`_
+* Small code size both in terms of source code with the minimum configuration
+  consisting of just three files, ``core.h``, ``format.h`` and ``format-inl.h``,
+  and compiled code; see `Compile time and code bloat`_
+* Reliability: the library has an extensive set of `tests
+  <https://github.com/fmtlib/fmt/tree/master/test>`_ and is `continuously fuzzed
+  <https://bugs.chromium.org/p/oss-fuzz/issues/list?colspec=ID%20Type%20
+  Component%20Status%20Proj%20Reported%20Owner%20Summary&q=proj%3Dlibfmt&can=1>`_
+* Safety: the library is fully type safe, errors in format strings can be
+  reported at compile time, automatic memory management prevents buffer overflow
+  errors
+* Ease of use: small self-contained code base, no external dependencies,
+  permissive MIT `license
+  <https://github.com/fmtlib/fmt/blob/master/LICENSE.rst>`_
+* `Portability <https://fmt.dev/latest/index.html#portability>`_ with
+  consistent output across platforms and support for older compilers
+* Clean warning-free codebase even on high warning levels such as
+  ``-Wall -Wextra -pedantic``
+* Locale-independence by default
+* Optional header-only configuration enabled with the ``FMT_HEADER_ONLY`` macro
+
+See the `documentation <https://fmt.dev>`_ for more details.
+
+Examples
+--------
+
+**Print to stdout** (`run <https://godbolt.org/z/Tevcjh>`_)
+
+.. code:: c++
+
+    #include <fmt/core.h>
+
+    int main() {
+      fmt::print("Hello, world!\n");
+    }
+
+**Format a string** (`run <https://godbolt.org/z/oK8h33>`_)
+
+.. code:: c++
+
+    std::string s = fmt::format("The answer is {}.", 42);
+    // s == "The answer is 42."
+
+**Format a string using positional arguments** (`run <https://godbolt.org/z/Yn7Txe>`_)
+
+.. code:: c++
+
+    std::string s = fmt::format("I'd rather be {1} than {0}.", "right", "happy");
+    // s == "I'd rather be happy than right."
+
+**Print chrono durations** (`run <https://godbolt.org/z/K8s4Mc>`_)
+
+.. code:: c++
+
+    #include <fmt/chrono.h>
+
+    int main() {
+      using namespace std::literals::chrono_literals;
+      fmt::print("Default format: {} {}\n", 42s, 100ms);
+      fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
+    }
+
+Output::
+
+    Default format: 42s 100ms
+    strftime-like format: 03:15:30
+
+**Print a container** (`run <https://godbolt.org/z/MjsY7c>`_)
+
+.. code:: c++
+
+    #include <vector>
+    #include <fmt/ranges.h>
+
+    int main() {
+      std::vector<int> v = {1, 2, 3};
+      fmt::print("{}\n", v);
+    }
+
+Output::
+
+    {1, 2, 3}
+
+**Check a format string at compile time**
+
+.. code:: c++
+
+    std::string s = fmt::format(FMT_STRING("{:d}"), "don't panic");
+
+This gives a compile-time error because ``d`` is an invalid format specifier for
+a string.
+
+**Write a file from a single thread**
+
+.. code:: c++
+
+    #include <fmt/os.h>
+
+    int main() {
+      auto out = fmt::output_file("guide.txt");
+      out.print("Don't {}", "Panic");
+    }
+
+This can be `5 to 9 times faster than fprintf
+<http://www.zverovich.net/2020/08/04/optimal-file-buffer-size.html>`_.
+
+**Print with colors and text styles**
+
+.. code:: c++
+
+    #include <fmt/color.h>
+
+    int main() {
+      fmt::print(fg(fmt::color::crimson) | fmt::emphasis::bold,
+                 "Hello, {}!\n", "world");
+      fmt::print(fg(fmt::color::floral_white) | bg(fmt::color::slate_gray) |
+                 fmt::emphasis::underline, "Hello, {}!\n", "мир");
+      fmt::print(fg(fmt::color::steel_blue) | fmt::emphasis::italic,
+                 "Hello, {}!\n", "世界");
+    }
+
+Output on a modern terminal:

+================= ============= ===========
+
+{fmt} is the fastest of the benchmarked methods, ~35% faster than ``printf``.
+
+The above results were generated by building ``tinyformat_test.cpp`` on macOS
+10.14.6 with ``clang++ -O3 -DNDEBUG -DSPEED_TEST -DHAVE_FORMAT``, and taking the
+best of three runs. In the test, the format string ``"%0.10f:%04d:%+g:%s:%p:%c:%%\n"``
+or equivalent is filled 2,000,000 times with output sent to ``/dev/null``; for
+further details refer to the `source
+<https://github.com/fmtlib/format-benchmark/blob/master/tinyformat_test.cpp>`_.
+
+{fmt} is up to 10x faster than ``std::ostringstream`` and ``sprintf`` on
+floating-point formatting (`dtoa-benchmark <https://github.com/fmtlib/dtoa-benchmark>`_)
+and faster than `double-conversion <https://github.com/google/double-conversion>`_:

+
+Compile time and code bloat
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The script `bloat-test.py
+<https://github.com/fmtlib/format-benchmark/blob/master/bloat-test.py>`_
+from `format-benchmark <https://github.com/fmtlib/format-benchmark>`_
+tests compile time and code bloat for nontrivial projects.
+It generates 100 translation units and uses ``printf()`` or its alternative
+five times in each to simulate a medium sized project.  The resulting
+executable size and compile time (Apple LLVM version 8.1.0 (clang-802.0.42),
+macOS Sierra, best of three) is shown in the following tables.

+
+As you can see, {fmt} has 60% less overhead in terms of resulting binary code
+size compared to iostreams and comes pretty close to ``printf``. Boost Format
+and Folly Format have the largest overheads.
+
+``printf+string`` is the same as ``printf`` but with extra ``<string>``
+include to measure the overhead of the latter.

+
+Motivation
+----------
+
+So why yet another formatting library?
+
+There are plenty of methods for doing this task, from standard ones like
+the printf family of function and iostreams to Boost Format and FastFormat
+libraries. The reason for creating a new library is that every existing
+solution that I found either had serious issues or didn't provide
+all the features I needed.
+
+printf
+~~~~~~
+
+The good thing about ``printf`` is that it is pretty fast and readily available
+being a part of the C standard library. The main drawback is that it
+doesn't support user-defined types. ``printf`` also has safety issues although
+they are somewhat mitigated with `__attribute__ ((format (printf, ...))
+<https://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html>`_ in GCC.
+There is a POSIX extension that adds positional arguments required for
+`i18n <https://en.wikipedia.org/wiki/Internationalization_and_localization>`_
+to ``printf`` but it is not a part of C99 and may not be available on some
+platforms.
+
+iostreams
+~~~~~~~~~
+
+The main issue with iostreams is best illustrated with an example:
+
+.. code:: c++
+
+    std::cout << std::setprecision(2) << std::fixed << 1.23456 << "\n";
+
+which is a lot of typing compared to printf:
+
+.. code:: c++
+
+    printf("%.2f\n", 1.23456);
+
+Matthew Wilson, the author of FastFormat, called this "chevron hell". iostreams
+don't support positional arguments by design.
+
+The good part is that iostreams support user-defined types and are safe although
+error handling is awkward.
+
+Boost Format
+~~~~~~~~~~~~
+
+This is a very powerful library which supports both ``printf``-like format
+strings and positional arguments. Its main drawback is performance. According to
+various, benchmarks it is much slower than other methods considered here. Boost
+Format also has excessive build times and severe code bloat issues (see
+`Benchmarks`_).
+
+FastFormat
+~~~~~~~~~~
+
+This is an interesting library which is fast, safe and has positional arguments.
+However, it has significant limitations, citing its author:
+
+    Three features that have no hope of being accommodated within the
+    current design are:
+
+    * Leading zeros (or any other non-space padding)
+    * Octal/hexadecimal encoding
+    * Runtime width/alignment specification
+
+It is also quite big and has a heavy dependency, STLSoft, which might be too
+restrictive for using it in some projects.
+
+Boost Spirit.Karma
+~~~~~~~~~~~~~~~~~~
+
+This is not really a formatting library but I decided to include it here for
+completeness. As iostreams, it suffers from the problem of mixing verbatim text
+with arguments. The library is pretty fast, but slower on integer formatting
+than ``fmt::format_to`` with format string compilation on Karma's own benchmark,
+see `Converting a hundred million integers to strings per second
+<http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html>`_.

-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.

 0.9.
 
 
+Version 2.7.1
+-------------
+* Workaround crashes when virtual machines report incoherent x86 CPUID
+  information about numbers of cores and threads.
+  Thanks to Peter Bense for the report.
+* Use setenv() instead of putenv() when trying to force enable oneAPI L0
+  support, to avoid issues with applications that touch the environment,
+  thanks to Josh Hursey for the patch.
+* Add some warnings at the end of configure when GPU libraries are
+  missing on the system or their path is missing in the environment.
+
+
+Version 2.7.0
+-------------
+* Backends
+  + Add support for NUMA nodes and caches with more than 64 PUs across
+    multiple processor groups on Windows 11 and Windows Server 2022.
+  + Group objects are not created for Windows processor groups anymore,
+    except if HWLOC_WINDOWS_PROCESSOR_GROUP_OBJS=1 in the environment.
+  + Expose "Cluster" group objects on Linux kernel 5.16+ for CPUs
+    that share some internal cache or bus. This can be equivalent
+    to the L2 Cache level on some platforms (e.g. x86) or a specific
+    level between L2 and L3 on others (e.g. ARM Kungpeng 920).
+    Thanks to Jonathan Cameron for the help.
+    - HWLOC_DONT_MERGE_CLUSTER_GROUPS=1 may be set in the environment
+      to prevent these groups from being merged with identical caches, etc.
+  + Improve the oneAPI LevelZero backend:
+    - Expose subdevices such as "ze0.1" inside root OS devices ("ze0")
+      when the hardware contains multiple subdevices.
+    - Add many new attributes to describe device type, and the
+      numbers of slices, subslices, execution units and threads.
+    - Expose the memory information as LevelZeroHBM/DDR/MemorySize infos.
+  + Ignore the max frequencies of cores in Linux cpukinds when the
+    base frequencies are available (to avoid exposing hybrid CPUs
+    when Intel Turbo Boost Max 3.0 gives slightly different max
+    frequencies to CPU cores).
+    - May be reverted by setting HWLOC_CPUKINDS_MAXFREQ=1 in the environment.
+* Tools
+  + Add --grey and --palette options to switch lstopo to greyscale or
+    white-background-only graphics, or to tune individual colors.
+* Build
+  + Windows CMake builds now support non-MSVC compilers, detect several
+    features at build time, can build/run tests, etc.
+    Thanks to Michael Hirsch and Alexander Neumann .
+
+
+Version 2.6.0
+-------------
+* Backends
+  + Expose two cpukinds for energy-efficient cores (icestorm) and
+    high-performance cores (firestorm) on Apple M1 on Mac OS X.
+  + Use sysfs CPU "capacity" to rank hybrid cores by efficiency
+    on Linux when available (mostly on recent ARM platforms for now).
+  + Improve HWLOC_MEMBIND_BIND (without the STRICT flag) on Linux kernel
+    >= 5.15: If more than one node is given, the kernel may now use all
+    of them instead of only the first one before falling back to others.
+  + Expose cache os_index when available on Linux, it may be needed
+    when using resctrl to configure cache partitioning, memory bandwidth
+    monitoring, etc.
+  + Add a "XGMIHops" distances matrix in the RSMI backend for AMD GPU
+    interconnected through XGMI links.
+  + Expose AMD GPU memory information (VRAM and GTT) in the RSMI backend.
+  + Add OS devices such as "bxi0" for Atos/Bull BXI HCAs on Linux.
+* Tools
+  + lstopo has a better placement algorithm with respect to I/O
+    objects, see --children-order in the manpage for details.
+  + hwloc-annotate may now change object subtypes and cache or memory
+    sizes.
+* Build
+  + Allow to specify the ROCm installation for building the RSMI backend:
+    - Use a custom installation path if specified with --with-rocm=<dir>.
+    - Use /opt/rocm-<version> if specified with --with-rocm-version=<version>
+      or the ROCM_VERSION environment variable.
+    - Try /opt/rocm if it exists.
+    - See "How do I enable ROCm SMI and select which version to use?"
+      in the FAQ for details.
+  + Add a CMakeLists for Windows under contrib/windows-cmake/ .
+* Documentation
+  + Add FAQ entry "How do I create a custom heterogeneous and
+     asymmetric topology?"
+
+
+Version 2.5.0
+-------------
+* API
+  + Add hwloc/windows.h to query Windows processor groups.
+  + Add hwloc_get_obj_with_same_locality() to convert between objects
+    with same locality, for instance NUMA nodes and Packages,
+    or OS devices within a PCI device.
+  + Add hwloc_distances_transform() to modify distances structures.
+    - hwloc-annotate and lstopo have new distances-transform options.
+  + hwloc_distances_add() is replaced with _add_create() followed by
+    _add_values() and _add_commit(). See hwloc/distances.h for details.
+  + Add topology flags to mitigate binding modifications during
+    hwloc discovery, especially on Windows:
+    - HWLOC_TOPOLOGY_FLAG_RESTRICT_TO_CPUBINDING and _MEMBINDING
+      restrict discovery to PUs and NUMA nodes inside the binding.
+    - HWLOC_TOPOLOGY_FLAG_DONT_CHANGE_BINDING prevents from ever
+      changing the binding during discovery.
+* Backends
+  + Add a levelzero backend for oneAPI L0 devices, exposed as OS devices
+    of subtype "LevelZero" and name such as "ze0".
+    - Add hwloc/levelzero.h for interoperability between converting
+      between L0 API devices and hwloc cpusets or OS devices.
+  + Expose NEC Vector Engine cards on Linux as OS devices of subtype
+    "VectorEngine" and name "ve0", etc.
+    Thanks to Anara Kozhokanova, Tim Cramer and Erich Focht for the help.
+  + Add a NVLinkBandwidth distances structure between NVIDIA GPUs
+    (and POWER processor or NVSwitches) in the NVML backend,
+    and a XGMIBandwidth distances structure between AMD GPUs
+    in the RSMI backends.
+    - See "Topology Attributes: Distances, Memory Attributes and CPU Kinds"
+      in the documentation for details about these new distances.
+  + Add support for NUMA node 0 being offline in Linux, thanks to Jirka Hladky.
+* Build
+  + Add --with-cuda-version=<version> or look at the CUDA_VERSION
+    environment variable to find the appropriate CUDA pkg-config files.
+    Thanks to Stephen Herbein for the suggestion.
+    - Also add --with-cuda=<dir> to specify the CUDA installation path
+      manually (and its NVML and OpenCL components).
+      Thanks to Andrea Bocci for the suggestion.
+    - See "How do I enable CUDA and select which CUDA version to use?"
+      in the FAQ for details.
+* Tools
+  + lstopo now has a --windows-processor-groups option on Windows.
+  + hwloc-ps now has a --short-name option to avoid long/truncated
+    command path.
+  + hwloc-ps now has a --single-ancestor option to return a single
+    (possibly too large) object where a process is bound.
+  + hwloc-ps --pid-cmd may now query environment variables,
+    including MPI-specific variables to find out process ranks.
+
+
+Version 2.4.1
+-------------
+* Fix AMD OpenCL device locality when PCI bus or device number >= 128.
+  Thanks to Edgar Leon for reporting the issue.
+  + Applications using any of the following inline functions must
+    be recompiled to get the fix: hwloc_opencl_get_device_pci_busid()
+    hwloc_opencl_get_device_cpuset(), hwloc_opencl_get_device_osdev().
+* Fix the ranking of cpukinds on non-Windows systems,
+  thanks to Ivan Kochin for the report.
+* Fix the insertion of custom Groups after loading the topology,
+  thanks to Scott Hicks.
+* Add support for CPU0 being offline in Linux, thanks to Garrett Clay.
+* Fix missing x86 Package and Core objects FreeBSD/NetBSD.
+  Thanks to Thibault Payet and Yuri Victorovich for the report.
+* Fix the import of very large distances with heterogeneous object types.
+* Fix a memory leak in the Linux backend,
+  thanks to Perceval Anichini.
+
+
+Version 2.4.0
+-------------
+* API
+  + Add hwloc/cpukinds.h for reporting information about hybrid CPUs.
+    - Use Linux cpufreq frequencies to rank cores by efficiency.
+    - Use x86 CPUID hybrid leaf and future Linux kernels sysfs CPU type
+      files to identify Intel Atom and Core cores.
+    - Use the Windows native EfficiencyClass to separate kinds.
+* Backends
+  + Properly handle Linux kernel 5.10+ exposing ACPI HMAT information
+    with knowledge of Generic Initiators.
+* Tools
+  + lstopo has new --cpukinds and --no-cpukinds options for showing
+    CPU kinds or not in textual and graphical modes respectively.
+  + hwloc-calc has a new --cpukind option for filtering PUs by kind.
+  + hwloc-annotate has a new cpukind command for modifying CPU kinds.
+* Misc
+  + Fix hwloc_bitmap_nr_ulongs(), thanks to Norbert Eicker.
+  + Add a documentation section about
+    "Topology Attributes: Distances, Memory Attributes and CPU Kinds".
+  + Silence some spurious warnings in the OpenCL backend and when showing
+    process binding with lstopo --ps.
+
+
+Version 2.3.0
+-------------
+* API
+  + Add hwloc/memattrs.h for exposing latency/bandwidth information
+    between initiators (CPU sets for now) and target NUMA nodes,
+    typically on heterogeneous platforms.
+    - When available, bandwidths and latencies are read from the ACPI HMAT
+      table exposed by Linux kernel 5.2+.
+    - Attributes may also be customized to expose user-defined performance
+      information.
+  + Add hwloc_get_local_numanode_objs() for listing NUMA nodes that are
+    local to some locality.
+  + The new topology flag HWLOC_TOPOLOGY_FLAG_IMPORT_SUPPORT causes
+    support arrays to be loaded from XML exported with hwloc 2.3+.
+    - hwloc_topology_get_support() now returns an additional "misc"
+      array with feature "imported_support" set when support was imported.
+  + Add hwloc_topology_refresh() to refresh internal caches after modifying
+    the topology and before consulting the topology in a multithread context.
+* Backends
+  + Add a ROCm SMI backend and a hwloc/rsmi.h helper file for getting
+    the locality of AMD GPUs, now exposed as "rsmi" OS devices.
+    Thanks to Mike Li.
+  + Remove POWER device-tree-based topology on Linux,
+    (it was disabled by default since 2.1).
+* Tools
+  + Command-line options for specifying flags now understand comma-separated
+    lists of flag names (substrings).
+  + hwloc-info and hwloc-calc have new --local-memory --local-memory-flags
+    and --best-memattr options for reporting local memory nodes and filtering
+    by memory attributes.
+  + hwloc-bind has a new --best-memattr option for filtering by memory attributes
+    among the memory binding set.
+  + Tools that have a --restrict option may now receive a nodeset or
+    some custom flags for restricting the topology.
+  + lstopo now has a --thickness option for changing line thickness in the
+    graphical output.
+  + Fix lstopo drawing when autoresizing on Windows 10.
+  + Pressing the F5 key in lstopo X11 and Windows graphical/interactive outputs
+    now refreshes the display according to the current topology and binding.
+  + Add a tikz lstopo graphical backend to generate picture easily included into
+    LaTeX documents. Thanks to Clement Foyer.
+* Misc
+  + The default installation path of the Bash completion file has changed to
+    ${datadir}/bash-completion/completions/hwloc. Thanks to Tomasz Kłoczko.

+ * Platforms with heterogeneous CPUs may have some cores with

+ *
+ * The number of kinds may be obtained with hwloc_cpukinds_get_nr().
+ * If the platform is homogeneous, there may be a single kind

+ *
+ * The index of the kind that describes a given CPU set

+ *
+ * From the index of a kind, it is possible to retrieve information

+ * (for instance the "CoreType" and "FrequencyMaxMHz",
+ *  see \ref topoattrs_cpukinds).
+ *
+ * A higher efficiency value means greater intrinsic performance
+ * (and possibly less performance/power efficiency).
+ * Kinds with lower efficiency values are ranked first:
+ * Passing 0 as \p kind_index to hwloc_cpukinds_get_info() will
+ * return information about the CPU kind with lower performance
+ * but higher energy-efficiency.

+ * This is currently available on Windows 10, Mac OS X (Darwin),
+ * and on some Linux platforms where core "capacity" is exposed in sysfs.
+ *
+ * If the operating system does not expose core efficiencies natively,

+ * frequencies (on ARM), or core types and frequencies (on other architectures).
+ * The environment variable HWLOC_CPUKINDS_RANKING may be used
+ * to change this heuristics, see \ref envvar.
+ *

+/** \defgroup hwlocality_memattrs Comparing memory node attributes for finding where to allocate on
+ *
+ * Platforms with heterogeneous memory require ways to decide whether
+ * a buffer should be allocated on "fast" memory (such as HBM),
+ * "normal" memory (DDR) or even "slow" but large-capacity memory
+ * (non-volatile memory).
+ * These memory nodes are called "Targets" while the CPU accessing them
+ * is called the "Initiator". Access performance depends on their
+ * locality (NUMA platforms) as well as the intrinsic performance
+ * of the targets (heterogeneous platforms).
+ *
+ * The following attributes describe the performance of memory accesses
+ * from an Initiator to a memory Target, for instance their latency
+ * or bandwidth.
+ * Initiators performing these memory accesses are usually some PUs or Cores
+ * (described as a CPU set).
+ * Hence a Core may choose where to allocate a memory buffer by comparing
+ * the attributes of different target memory nodes nearby.
+ *
+ * There are also some attributes that are system-wide.
+ * Their value does not depend on a specific initiator performing
+ * an access.
+ * The memory node Capacity is an example of such attribute without
+ * initiator.
+ *
+ * One way to use this API is to start with a cpuset describing the Cores where
+ * a program is bound. The best target NUMA node for allocating memory in this
+ * program on these Cores may be obtained by passing this cpuset as an initiator
+ * to hwloc_memattr_get_best_target() with the relevant memory attribute.
+ * For instance, if the code is latency limited, use the Latency attribute.
+ *
+ * A more flexible approach consists in getting the list of local NUMA nodes
+ * by passing this cpuset to hwloc_get_local_numanode_objs().
+ * Attribute values for these nodes, if any, may then be obtained with
+ * hwloc_memattr_get_value() and manually compared with the desired criteria.
+ *
+ * \note The API also supports specific objects as initiator,
+ * but it is currently not used internally by hwloc.
+ * Users may for instance use it to provide custom performance
+ * values for host memory accesses performed by GPUs.
+ *
+ * \note The interface actually also accepts targets that are not NUMA nodes.
