Abstract
Using way-locking to record plural execution contexts into independent execution traces. A processor partitions a cache into a first subset of ways that are locked to a first context recorded into a first trace and a second subset of ways that are locked to a second context recorded into a second trace. The processor also detects a memory operation by the first context into the second cache subset. The processor then performs at least one of: when the memory operation causes an influx into the second cache subset, initiating logging of the influx to the second trace; when the memory operation is a read from the second cache subset, initiating logging of the read to the first trace; or when the memory operation is a write to the second cache subset, performing one of initiating logging of the write to the second trace, or evicting a target cache line.
