26 | * Fault Management Architecture (FMA) Resource and Protocol Support | |
27 | * | |
28 | * The routines contained herein provide services to support kernel subsystems | |
29 | * in publishing fault management telemetry (see PSARC 2002/412 and 2003/089). | |
30 | * | |
31 | * Name-Value Pair Lists | |
32 | * | |
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. | |
39 | * | |
40 | * Protocol Event and FMRI Construction | |
41 | * | |
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. | |
45 | * | |
46 | * ENA Manipulation | |
47 | * | |
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(). | |
