Subject: [dpdk-dev] DPDK memory error check and offline bad pages
Date: Wed, 08 Nov 2017 05:13:01 +0800 [thread overview]
Message-ID: <8585190C-A984-4563-BF89-97CEFE6B87AB@alibaba-inc.com> (raw)
Hi dpdk developers,
I have a question regarding how DPDK memory module treats memory errors.
In Linux kernel, it has mechanism (mcelog and EDAC) to monitor the memory controller and report correctable/uncorrectable memory errors. Using some configurations, if memory errors exceed threshold, system can offline bad memory pages and avoid applications to access/crash.
Do we have similar mechanism in DPDK?
Thanks,
Jianjian
