/*
* The ereport and fault events are declared at multiple levels:
* some set of @chip, @core, and @strand resources since this is
* a generic DE and must be flexible and handle present and future
* sun4v platforms. For example, one processor may have an L2
* cache per chip, another may have an L2 per core.
*
* For UE errors, faults are produced immediately.
*
* For CE errors, the errors are put through a SERD engine. If
* the SERD engine trips, the fault is produced. SERD engine
* names are of the format:
* serd.cpu.generic-sparc.<resource><suffix>
* Ex: serd.cpu.generic-sparc.chipitlb
* SERD N/T values are set to default values, but can be
* overridden via the ereport or the eft.conf file. The
* order or precedence of the SERD N/T values is:
* - the 'serd_override' tunable via eft.conf
* - the 'serd_n' and 'serd_t' payload members in the
* incoming ereport
* - the built-in default values
*
* The increment rate of the SERD engines can also be
* controlled via the ereport payload using the 'filter_ratio'
* payload member. N in incremented by the value of
* 'filter_ratio' if the payload member is present, 1 otherwise.
