 Reserving Hugepages for DPDK Use
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-The allocation of hugepages should be done at boot time or as soon as possible after system boot
-to prevent memory from being fragmented in physical memory.
+The reservation of hugepages can be performed at run time. This is done by
+echoing the number of hugepages required to a ``nr_hugepages`` file in the
+``/sys/kernel/`` directory corresponding to a specific page size (in
+Kilobytes). For a single-node system, the command to use is as follows
+(assuming that 1024 of 2MB pages are required)::
+
+    echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
+
+On a NUMA machine, the above command will usually divide the number of hugepages
+equally across all NUMA nodes (assuming there is enough memory on all NUMA
+nodes). However, pages can also be reserved explicitly on individual NUMA
+nodes using a ``nr_hugepages`` file in the ``/sys/devices/`` directory::
+
+    echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
+    echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages

+    Some kernel versions may not allow reserving 1 GB hugepages at run time, so

+
+In the general case, reserving hugepages at run time is perfectly fine, but in

+physical memory from becoming heavily fragmented.

 To reserve hugepages at boot time, a parameter is passed to the Linux kernel on the kernel command line.
 
 For 2 MB pages, just pass the hugepages option to the kernel. For example, to reserve 1024 pages of 2 MB, use::

 Using Hugepages with the DPDK
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-Once the hugepage memory is reserved, to make the memory available for DPDK use, perform the following steps::
+If secondary process support is not required, DPDK is able to use hugepages
+without any configuration by using "in-memory" mode. Please see
+:ref:`linux_eal_parameters` for more details.
+
+If secondary process support is required, mount points for hugepages need to be
+created. On modern Linux distributions, a default mount point for hugepages is provided
+by the system and is located at ``/dev/hugepages``. This mount point will use the
+default hugepage size set by the kernel parameters as described above.
+
+However, in order to use hugepage sizes other than the default, it is necessary
+to manually create mount points for those hugepage sizes (e.g. 1GB pages).
+
+To make the hugepages of size 1GB available for DPDK use, perform the following steps::
 
     mkdir /mnt/huge
-    mount -t hugetlbfs nodev /mnt/huge
+    mount -t hugetlbfs pagesize=1GB /mnt/huge
 
 The mount point can be made permanent across reboots, by adding the following line to the ``/etc/fstab`` file::
 
-    nodev /mnt/huge hugetlbfs defaults 0 0
-
-For 1GB pages, the page size must be specified as a mount option::
-
-    nodev /mnt/huge_1GB hugetlbfs pagesize=1GB 0 0
+    nodev /mnt/huge hugetlbfs pagesize=1GB 0 0
