/*
* 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().
