[dpdk-dev] DPDK memory error check and offline bad pages

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
