## Type Definitions

### `AcdbSubgraphProcPair`

```cpp theme={null}
typedef struct _acdb_subgraph_proc_pair_t AcdbSubgraphProcPair
```

### `AcdbProcSubgraphPersistCalReq`

```cpp theme={null}
typedef struct _acdb_proc_subgraph_persist_cal_req_t AcdbProcSubgraphPersistCalReq
```

## Macros

### `ACDB_CMD_GET_PROC_SUBGRAPH_CAL_DATA_PERSIST`

Retrieves subgraph calibration data for persistent parameters under a given processor.

```c theme={null}
#define ACDB_CMD_GET_PROC_SUBGRAPH_CAL_DATA_PERSIST ACDB_CMD_ID(29)
```

### `ACDB_HW_ACCEL_MEM_TYPE_MASK`

Extracts the hardware acceleration memory type from the processor domain ID.

```c theme={null}
#define ACDB_HW_ACCEL_MEM_TYPE_MASK (proc_id + (mem_type << 30))
```

### `ACDB_HW_ACCEL_MEM_TYPE`

Extracts proc id from processor domain ID.

```c theme={null}
#define ACDB_HW_ACCEL_MEM_TYPE ((AcdbHwAccelMemType)(proc_id >> 30))
```

### `ACDB_HW_ACCEL_PROC_ID`

```c theme={null}
#define ACDB_HW_ACCEL_PROC_ID (proc_id & 0x3FFFFFFF)
```
