- * SCT(System Cache Table) entry contains of the following members:
- * usecase_id: Unique id for the client's use case
- * slice_id: llcc slice id for each client
- * max_cap: The maximum capacity of the cache slice provided in KB
- * priority: Priority of the client used to select victim line for replacement
- * fixed_size: Boolean indicating if the slice has a fixed capacity
- * bonus_ways: Bonus ways are additional ways to be used for any slice,
- * if client ends up using more than reserved cache ways. Bonus
- * ways are allocated only if they are not reserved for some
- * other client.
- * res_ways: Reserved ways for the cache slice, the reserved ways cannot
- * be used by any other client than the one its assigned to.
- * cache_mode: Each slice operates as a cache, this controls the mode of the
- * slice: normal or TCM(Tightly Coupled Memory)
- * probe_target_ways: Determines what ways to probe for access hit. When
- * configured to 1 only bonus and reserved ways are probed.
- * When configured to 0 all ways in llcc are probed.
- * dis_cap_alloc: Disable capacity based allocation for a client
- * retain_on_pc: If this bit is set and client has maintained active vote
- * then the ways assigned to this client are not flushed on power
- * collapse.
- * activate_on_init: Activate the slice immediately after the SCT is programmed
