AMD Athlon Processor Model 6 Revision Guide
24332G—October 2003
Preliminary Information
17
Deadlock May Occur in a Two-Processor System in the Presence of Probe to Memory-
Mapped I/O
Products Affected.
A0, A2, A5
Normal Specified Operation.
Processor should not hang.
Non-conformance.
In a multiprocessor system, if one processor (A) is continuously writing to a cacheable
memory-mapped I/O block while the other processor (B) is trying to read the same cacheable I/O block,
and at the same time both processors are also trying to write a different memory-based cache block,
then processor B may hang. Should this occur and processor A fields an interrupt, the deadlock will be
resolved.
Potential Effect on System.
System will hang or exhibit performance degradation.
Suggested Workaround.
The current processor design assumes that memory-mapped I/O is incoherent and
does not handle all deadlock cases. System logic should not generate probes for memory mapped I/O
addresses.
Resolution Status.
No fix planned.
