+#### `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`).

 #### `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.

+Use continuous, persistent memory block for mining threads, useful for preserve huge pages allocation while algorithm swithing. Possible values `false` (feature disabled, by default) or `true` or specific count of 2 MB huge pages. It helps to avoid loosing huge pages for scratchpads when RandomX dataset is updated and mining threads restart after a 2-3 days of mining.

 0.9.


+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.

+ *
+ * The number of kinds may be obtained with hwloc_cpukinds_get_nr().

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

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

+ *  see \ref topoattrs_cpukinds).

+ * A higher efficiency value means intrinsic greater performance
+ * (and possibly less performance/power efficiency).
+ * Kinds with lower efficiency are ranked first:
+ * Passing 0 as \p kind_index to hwloc_cpukinds_get_info() will

+ * When available, efficiency values are gathered from the operating
+ * system (when \p cpukind_efficiency is set in the

+ * by comparing CPU kinds using frequencies (on ARM),

+ * The environment variable HWLOC_CPUKINDS_RANKING may be used
+ * to change this heuristics, see \ref envvar.
+ *
+ * If hwloc fails to rank any kind, for instance because the operating

+ *
+ * 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.

- * \version  0.4.0
- *
- * Version history:
- *
- * * 0.1.0 (2008-10-15): initial adaptation from wxfractgui sources
- * * 0.1.1 (2009-07-06): Added intel_fn11 fields to cpu_raw_data_t to handle
- *                       new processor topology enumeration required on Core i7
- * * 0.1.2 (2009-09-26): Added support for MSR reading through self-extracting
- *                       kernel driver on Win32.
- * * 0.1.3 (2010-04-20): Added support for greater more accurate CPU clock
- *                       measurements with cpu_clock_by_ic()
- * * 0.2.0 (2011-10-11): Support for AMD Bulldozer CPUs, 128-bit SSE unit size
- *                       checking. A backwards-incompatible change, since the
- *                       sizeof cpu_id_t is now different.
- * * 0.2.1 (2012-05-26): Support for Ivy Bridge, and detecting the presence of

- * * 0.3.0 (2016-07-09): Support for Skylake; MSR ops in FreeBSD; INFO_VOLTAGE
- *                       for AMD CPUs. Level 4 cache support for Crystalwell
- *                       (a backwards-incompatible change since the sizeof
- *                        cpu_raw_data_t is now different).
- * * 0.4.0 (2016-09-30): Better detection of AMD clock multiplier with msrinfo.
- *                       Support for Intel SGX detection
- *                       (a backwards-incompatible change since the sizeof
- *                        cpu_raw_data_t and cpu_id_t is now different).

-/** @mainpage A simple libcpuid introduction
- * 
- * LibCPUID provides CPU identification and access to the CPUID and RDTSC
- * instructions on the x86.
- * <p>
- * To execute CPUID, use \ref cpu_exec_cpuid <br>
- * To execute RDTSC, use \ref cpu_rdtsc <br>
- * To fetch the CPUID info needed for CPU identification, use
- *   \ref cpuid_get_raw_data <br>
- * To make sense of that data (decode, extract features), use \ref cpu_identify <br>
- * To detect the CPU speed, use either \ref cpu_clock, \ref cpu_clock_by_os,
- * \ref cpu_tsc_mark + \ref cpu_tsc_unmark + \ref cpu_clock_by_mark,
- * \ref cpu_clock_measure or \ref cpu_clock_by_ic.
- * Read carefully for pros/cons of each method. <br>
- * 
- * To read MSRs, use \ref cpu_msr_driver_open to get a handle, and then
- * \ref cpu_rdmsr for querying abilities. Some MSR decoding is available on recent
- * CPUs, and can be queried through \ref cpu_msrinfo; the various types of queries
- * are described in \ref cpu_msrinfo_request_t.
