#  This file is a modified version of dev-hugepages.mount from systemd.
#
#  With this unit file enabled you can set 1GB hugepages using kernel args
#  and have them auto mounted, just as you would with 2MB hugepages.
#
#  For normal systems use "hugepagesz=1G hugepages=16"
#  to allocate 16 hugepages with a pagesize of 1GB
#  
#  For systems with numa nodes use "hugepagesz=1G hugepages=0:16"
#  to allocate 16 hugepages on numa node 0 with a pagesize of 1GB
# 
#  For more info, consult the kernel.org documentation linked in this file
