Notes:
1. The IA32_MC0_MISC register details will be available upon implementation in a future processor stepping.
2. The MCi_ADDR and MCi_MISC registers for machine check banks 2 & 4 are not implemented on the processors. The MCi_CTL
register for machine check bank 2 is also not implemented.
3. The PECI host must determine the total number of machine check banks and the validity of the MCi_ADDR and MCi_MISC
register contents prior to issuing a read to the machine check bank similar to standard machine check architecture
enumeration and accesses.
4. The information presented in Table 2-11 is applicable to the processor only. No association between bank numbers and logical
functions should be assumed for any other processor devices (past, present or future) based on the information presented in
Table 2-11.
5. The processor machine check banks 4 through 19 reside in the processor uncore and hence will return the same value
independent of the processor ID used to access these banks.
6. The IA32_MCG_STATUS, IA32_MCG_CONTAIN and IA32_MCG_CAP are located in the uncore and will return the same value
independent of the processor ID used to access them.
7. The processor machine check banks 0 through 3 are core-specific. Since the processor ID is thread-specific and not core-
specific, machine check banks 0 through 3 will return the same value for a particular core independent of the thread
referenced by the processor ID.
8. PECI accesses to the machine check banks may not be possible in the event of a core hang. A warm reset of the processor
may be required to read any sticky machine check banks.
9. Valid processor ID values may be obtained by using the enumeration methods described in Section 2.5.2.7.2.
10. Reads to a machine check bank within a core or thread that is disabled will return all zeroes with a completion code of 0x90.
11. For SKUs where Intel QPI is disabled or absent, reads to the corresponding machine check banks will return all zeros with a
completion code of 0x40.
