Cache Information
This tab displays information about the processor's cache. There are two types of information listed, explicit and non-explicit. The CPUID instruction has two different cache information calls, one for getting the explicit information (e.g. cache level, number of ways, line size, etc.) about each cache and another which is an array of 8-bit identifiers used to identify the cache information.
The explicit cache information is useful for calculating the size of a cache in the event of the programmer wanting to limit data to certain sizes (i.e. limiting the amount of data being worked on at any given time to avoid thrashing the cache). The non-explicit cache information is purely for informational purposes.
CLFLUSH Line Size specifies the number of bytes that gets flushed from the cache when issuing the CLFLUSH instruction. This is typically the same as the actual line size of the cache and is naturally aligned to the number of bytes specified.
