Errata

Specification Update
corresponds to 64K bytes for 16 bit address size and 4G bytes for 32 bit
address size.
Implication: (E)CX may contain an incorrect count which may cause some of the STOS
operations to re-execute. Intel has not observed this erratum with any
commercially available software.
Workaround: Do not use values in (E)CX that when multiplied by the data size give values
larger than the address space size (64K for 16-bit address size and 4G for
32-bit address size).
Status: For the steppings affected, see the Summary Tables of Changes.
AI102. Performance Monitoring Event BR_INST_RETIRED May Count CPUID
Instructions as Branches
Problem: Performance monitoring event BR_INST_RETIRED (C4H) counts retired
branch instructions. Due to this erratum, two of its sub-events mistakenly
count for CPUID instructions as well. Those sub events are:
BR_INST_RETIRED.PRED_NOT_TAKEN (Umask 01H) and
BR_INST_RETIRED.ANY (Umask 00H).
Implication: The count value returned by the performance monitoring event
BR_INST_RETIRED.PRED_NOT_TAKEN or BR_INST_RETIRED.ANY may be
higher than expected. The extent of over counting depends on the occurrence
of CPUID instructions, while the counter is active.
Workaround: None identified.
Status: For the steppings affected, see the Summary Tables of Changes.
AI103. Performance Monitoring Event MISALIGN_MEM_REF May Over Count
Problem: Performance monitoring event MISALIGN_MEM_REF (05H) is used to count
the number of memory accesses that cross an 8-byte boundary and are
blocked until retirement. Due to this erratum, the performance monitoring
event MISALIGN_MEM_REF also counts other memory accesses.
Implication: The performance monitoring event MISALIGN_MEM_REF may over count. The
extent of over counting depends on the number of memory accesses retiring
while the counter is active.
Workaround: None identified.
Status: For the steppings affected, see the Summary Tables of Changes.
AI104. A REP STOS/MOVS to a MONITOR/MWAIT Address Range May
Prevent Triggering of the Monitoring Hardware
Problem: The MONITOR instruction is used to arm the address monitoring hardware for
the subsequent MWAIT instruction. The hardware is triggered on subsequent
memory store operations to the monitored address range. Due to this
erratum, REP STOS/MOVS fast string operations to the monitored address
