x86: Fault Management For Next Generation AMD Opteron Processors

The fault management feature introduces error-handling and fault-management support for CPUs and memory in systems that use AMD (TM) Opteron and Athlon 64 Rev F processors. These processors are used in the “M2” products from Sun such as the Sun Fire X2200 M2 and Ultra 20 M2. Previous Solaris releases provided fault management support for Opteron and Athlon 64 revisions B through E.

Fault management support is enabled by default. The fault management service detects correctable CPU and memory errors, the resulting telemetry is analyzed by diagnosis engines, and errors and faults are corrected whenever possible. When errors cannot be corrected by the system, the extended telemetry provides greater assistance to the system administrator.
