AMD Athlon™ Processor Model 6 Revision Guide

24332E— December2002

17Deadlock 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.
