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