Product: DPDK
Version: 18.11
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: maaaah@mail.ru
Target Milestone: ---
I am trying to allocate 32Gb memory via rte_calloc applying config changes
advised in https://bugs.dpdk.org/show_bug.cgi?id=608. I am using 1Gb hugepages.
However, in order to success, the system requires to reserve 66 pages which is
too much - we just don't have enough RAM on our production hosts.
Please advise.
