+ * Fault Management Architecture (FMA) Resource and Protocol Support
+ *
+ * The routines contained herein provide services to support kernel subsystems
+ * in publishing fault management telemetry (see PSARC 2002/412 and 2003/089).
+ *
+ * Name-Value Pair Lists
+ *
+ * The embodiment of an FMA protocol element (event, fmri or authority) is a
+ * name-value pair list (nvlist_t). FMA-specific nvlist construtor and
+ * destructor functions, fm_nvlist_create() and fm_nvlist_destroy(), are used
+ * to create an nvpair list using custom allocators. Callers may choose to
+ * allocate either from the kernel memory allocator, or from a preallocated
+ * buffer, useful in constrained contexts like high-level interrupt routines.
+ *
+ * Protocol Event and FMRI Construction
+ *
+ * Convenience routines are provided to construct nvlist events according to
+ * the FMA Event Protocol and Naming Schema specification for ereports and
+ * FMRIs for the dev, cpu, hc, mem, legacy hc and de schemes.
+ *
+ * ENA Manipulation
+ *
+ * Routines to generate ENA formats 0, 1 and 2 are available as well as
+ * routines to increment formats 1 and 2. Individual fields within the
+ * ENA are extractable via fm_ena_time_get(), fm_ena_id_get(),
+ * fm_ena_format_get() and fm_ena_gen_get().
