Way partitioning for a system-level cache

A system comprising:

• multiple integrated client devices;
• a memory controller configured to read data from a memory device;
• and
• a system-level cache configured to cache data requests through the memory controller for each of the multiple integrated client devices,
• wherein the system-level cache comprises a cache memory having multiple ways, each way of the multiple ways being a primary way or a secondary way,
• wherein each primary way is dedicated to a single respective partition corresponding to a memory buffer accessed by one or more client devices, and
• wherein each secondary way is shared by a group of multiple partitions corresponding to multiple memory buffers accessed by a group of client devices, and
• wherein the system-level cache is configured to maintain a mapping between partitions and priority levels and is configured to allocate primary ways to respective enabled partitions in an order corresponding to the respective priority levels assigned to the enabled partitions.
