Managing a programmable cache control mapping table in a system level cache

A system, comprising:

• a memory;
• a plurality of cache memory clients that is coupled to the memory;
• a mapping table that maps a client type identifier and a buffer type associated with a request to a table entry index;
• a cache memory policy manager configured to:
• monitor telemetric data that measures a system state of the system;
• determine whether the system state is consistent with a previously identified system state included in a set of previously identified system states;
• and
• if the system state is consistent with a first previously identified system state included in the set of previously identified system states, then:
• update the mapping table with table entry indices appropriate for each combination of client type identifier and buffer type for the first previously identified system state, or
• if the system state is not consistent with any previously identified system state included in the set of previously identified system states, then:
• update the mapping table with the table entry indices appropriate for each combination of client type identifier and buffer type for a default system state;
• and
• a cache memory controller configured to:
• read one or more cache control parameters from a table entry referenced by a first table entry index included in the table entry indices.
