Detailed Description

The PPU driver provides APIs to configure and control default power policy behavior and dynamic transition settings for supported PPU instances.

Features:

• Configure default power policy using ppu_set_power_mode.
• Enable or disable dynamic transition behavior using ppu_set_dynamic_transition.
• Per-instance validation and register programming through the PPU driver context.

Configuration Considerations

Typical usage flow:

1. Select the target PPU instance identifier (for example, PPU_INSTANCE_0).
2. Configure default policy using ppu_set_power_mode.
3. Configure autonomous transition behavior using ppu_set_dynamic_transition.

Usage Examples

Set Baseline Power Mode

if (ppu_set_power_mode(PPU_INSTANCE_0, PM_STATE_MEM_RET) != 0) {
    /* handle error */
}

Enable Dynamic Transition

if (ppu_set_dynamic_transition(PPU_INSTANCE_0, true) != 0) {
    /* handle error */
}
