[Xen-devel] [PATCH 4] MCA physical address check when calculate domain |
Before Nehalem memory errors were reported via NMI ... use of
MCA for this (and thus use of MCi_ADDR) begins with the memory
controller moving on-die.
So if you are interested in memory errors - you are out of luck
on pre-NHM systems.
MCi_ADDR on the pre-NHM systems was sometimes used to report
cache errors (index/rank/...)
