/cacheline qualifier informs KAP of the width of
the memory channel in bytes between cache and main memory.
/cacheline qualifier can take a second argument,
When two arguments are specified, the first argument gives the width of the memory channel between the primary cache and the secondary cache and the second argument gives the width of the memory channel between the secondary cache and main memory. Omitting the second argument, or specifying it as 32 (the default), tells KAP to not optimize secondary cache usage.
