Abstract
Trace logging based on an upper cache layer determining how to log an influx by a lower cache layer. A second cache receives, from a lower layer first cache, a logging request referencing a memory address. The second cache determines whether it has a cache line for the memory address. When the cache line is present, the second cache either forwards the request to a next logging cache layer or causes the cache line to be logged if second cache is the outermost logging layer. When the cache line isn't present, the second cache causes the cache line to be logged when the cache line isn't determined by the second cache to be logged, or when it is determined by the second cache to be logged but it is not determined whether the first cache is aware of a current value of the cache line in the second cache.
