            Bug ID: 1370
           Summary: DTS: configure hugepage size as well as quantity
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: dts
          Assignee: dev@dpdk.org
          Reporter: jspewock@iol.unh.edu
                CC: juraj.linkes@pantheon.tech, probb@iol.unh.edu
  Target Milestone: ---

Currently the config file we have allows you to configure the number of huge
pages (defaulted to 256), but it doesn't do anything to change the size.
Creating 256 2M hugepages is very different from creating 256 1G hugepages and
if you run this default config on a host where you have the default hugepage
size set to 1G, this would cause major problems for hosts without enough memory
to support 256gb of hugepages.Of course this configuration is optional, but
still would be ideal if it were slightly more configurable so that you can
control what you mean by 256 hugepages.
