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

[Jianjian Huo]

Anyone has any idea on this?
Can’t believe DPDK doesn’t support such an important feature. This is going to be a show stopper for real production system.

    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,
