Subject: [PATCH] eal/linux: enable the hugepage mem dump
Date: Tue, 8 Mar 2022 17:41:25 +0800 [thread overview]
Message-ID: <20220308094125.2716847-1-fengli@smartx.com> (raw)
These hugepages include important structures. We should dump these
hugepages into a coredump file for debugging when generating a coredump.
