It makes sense to use the kernel's performance events 
logging framework when we are logging events about how the 
system performs.

Furthermore it's NMI safe, offers structured logging, has 
various streaming, multiplexing and filtering capabilities 
that come handy for RAS purposes and more.

The other option would be to use an ad-hoc logging 
implementation, only used for EDAC/RAS, which couldnt be 
mixed with other system events. That approach has various 
obvious disadvanteges so we are aiming for a unified 
approach.

Thanks,
