== Introduction==
|
||||
|
||||
LLCC (Last Level Cache Controller) provides last level of cache memory in SOC,
|
||||
that can be shared by multiple clients. Clients here are different cores in the
|
||||
SOC, the idea is to minimize the local caches at the clients and migrate to
|
||||
common pool of memory. Cache memory is divided into partitions called slices
|
||||
which are assigned to clients. Clients can query the slice details, activate
|
||||
and deactivate them.
|
||||
|
||||
Properties:
|
||||
- compatible:
|
||||
Usage: required
|
||||
Value type: <string>
|
||||
Definition: must be "qcom,sdm845-llcc"
|
||||
|
||||
- reg:
|
||||
Usage: required
|
||||
Value Type: <prop-encoded-array>
|
||||
Definition: The first element specifies the llcc base start address and
|
||||
the size of the register region. The second element specifies
|
||||
the llcc broadcast base address and size of the register region.
|
||||
|
||||
- reg-names:
|
||||
Usage: required
|
||||
Value Type: <stringlist>
|
||||
Definition: Register region names. Must be "llcc_base", "llcc_broadcast_base".
|
||||
|
||||
- interrupts:
|
||||
Usage: required
|
||||
Definition: The interrupt is associated with the llcc edac device.
|
||||
It's used for llcc cache single and double bit error detection
|
||||
and reporting.
|
||||
|
||||
Example:
|
||||
|
||||
cache-controller@1100000 {
|
||||
compatible = "qcom,sdm845-llcc";
|
||||
reg = <0x1100000 0x200000>, <0x1300000 0x50000> ;
|
||||
reg-names = "llcc_base", "llcc_broadcast_base";
|
||||
interrupts = <GIC_SPI 582 IRQ_TYPE_LEVEL_HIGH>;

* 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
